The Critically Ill Infant: THE MISFITS
Trauma
* ‘T’ in the mnemonic stands for trauma, which includes both accidental and intentional causes.
* Considerations for Non-accidental Trauma:
* Stresses the importance of considering non-accidental trauma, especially given that it may not always present with obvious external signs.
* Anatomical Vulnerabilities:
* Highlights specific anatomical considerations for infants who suffer from trauma:
* Infants have proportionally larger heads, increasing their susceptibility to high cervical spine (c-spine) injuries.
* Their liver and spleen are less protected, making abdominal injuries potentially more severe.
Heart
* 5 T’s of Cyanotic Congenital Heart Disease: Introduces a mnemonic to help remember key right-sided ductal-dependent lesions:
* Truncus Arteriosus: Single vessel serving as both pulmonary and systemic outflow tract.
* Transposition of the Great Arteries: The pulmonary artery and aorta are switched, leading to improper circulation.
* Tricuspid Atresia: Absence of the tricuspid valve, leading to inadequate development of the right ventricle and pulmonary circulation issues.
* Tetralogy of Fallot: Comprises four defects—ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta.
* Total Anomalous Pulmonary Venous Connection (TAPVC): Pulmonary veins do not connect to the left atrium but rather to the right heart or veins, causing oxygen-rich blood to mix with oxygen-poor blood.
* Other Significant Conditions:
* Ebstein’s Anomaly: Malformation of the tricuspid valve affecting right-sided heart function.
* Pulmonary Atresia/Stenosis: Incomplete formation or narrowing of the pulmonary valve obstructs blood flow to the lungs.
* Left-sided Ductal-Dependent Lesions:
* Conditions such as aortic arch abnormalities (coarctation or interrupted arch), critical aortic stenosis, and hypoplastic left heart syndrome are highlighted. These generally present with less obvious cyanosis and more pallor.
* Diagnostic and Management Considerations:
* Routine prenatal ultrasounds detect most cases, but conditions like coarctation of the aorta and TAPVC might not be apparent until after birth when the ductus arteriosus closes.
* Emphasizes the importance of a thorough physical exam: checking for murmurs, assessing hepatosplenomegaly, feeling for femoral pulses, measuring pre- and post-ductal saturations,Wed, 01 May 2024 - 201 - Episode 195: ARDS

* Definition of ARDS:
* Non-cardiogenic pulmonary edema characterized by acute respiratory failure.
* Berlin criteria for diagnosis include acute onset within 7 days, bilateral pulmonary infiltrates on imaging, not fully explained by cardiac failure or fluid overload, and impaired oxygenation with PaO2/FiO2 ratio <300 mmHg, even with positive end-expiratory pressure (PEEP) >5 cm H2O.
* Severity based on oxygenation (Berlin criteria):
* Mild: PaO2/FiO2 200-300 mmHg
* Moderate: PaO2/FiO2 100-200 mmHg
* Severe: PaO2/FiO2 <100 mmHg
* Epidemiology:
* Occurs in up to 23% of mechanically ventilated patients.
* Mortality rate of 30-40%, primarily due to multiorgan failure.
* Differentiation from Cardiogenic Pulmonary Edema:
* Chest CT shows diffuse edema and pleural effusion in cardiogenic edema; patchy edema, dense consolidation in ARDS.
* Ultrasound may show diffuse B lines in cardiogenic edema; patchy B lines and normal A lines in ARDS.
* Pathophysiology:
* Exudative phase: Immune-mediated alveolar damage, pulmonary edema, cytokine release.
* Proliferative phase: Reabsorption of edema fluid.
* Fibrotic phase: Potential for prolonged ventilation.
* Etiology:
* Direct lung injury (pneumonia, toxins, aspiration, trauma, drowning) and indirect causes (sepsis, pancreatitis, transfusion reactions, certain drugs).
* Diagnostics:
* Comprehensive workup including imaging (chest X-ray, CT), laboratory tests (complete blood count, basic metabolic panel, blood gases), and specialized tests depending on suspected etiology.
* Management Strategies:
* Steroids: Beneficial in certain etiologies of ARDS, with specifics on dosing and duration.
* Fluid Management: Conservative fluid strategy, diuresis guided by patient condition.
* Ventilation: Non-invasive ventilation (NIV) preferred in specific cases; mechanical ventilation strategies to ensure lung-protective ventilation.
* Proning: Used in severe ARDS to improve oxygenation.
* Inhaled Vasodilators: Used for refractory hypoxemia and specific complications like right heart failure.
* Extracorporeal Membrane Oxygenation (ECMO): Considered for severe ARDS as salvage therapy.
* Supportive Care: Includes monitoring and management of complications, nutrition, and physical therapy.
* Ventilation Specifics:
* Tidal volume and pressure settings aim for lung-protective strategies to prevent ventilator-induced lung injury.
* Permissive hypercapnia, plateau pressure, PEEP,Mon, 01 Apr 2024 - 200 - Episode 194: Nitrous Oxide Toxicity

Patient Case Illustration
* Hypothetical case: 21-year-old male with no previous medical history, experiencing a month of progressively worsening numbness, tingling, and weakness. Initially starting in his toes and spreading to his hips, and later involving his hands, the symptoms eventually escalated to the point of immobilization. Despite initially denying drug use, the patient admitted to using 40-60 canisters of nitrous oxide (whippets) every weekend for the last three months.
Background and Recreational Use of Nitrous Oxide
* Nitrous oxide, a colorless, odorless gas with anesthetic properties.
* Synthesized in the 18th century.
* Its initial medical purpose expanded into recreational use due to its euphoric effects.
* Resurgence as a recreational drug during the COVID-19 lockdowns.
* Accessibility and legal status.
Public Misconceptions and Health Consequences
* There are widespread misconceptions about nitrous oxide
* Particularly the belief in its safety and lack of long-term health risks.
* Contrary to popular belief, frequent use of nitrous oxide can lead to significant, sometimes irreversible, health issues.
Neurological Examination and Diagnosis
* Key components of the examination include assessing strength, sensation, cranial nerves, and proprioception, with specific abnormalities such as symmetrically decreased strength in a stocking-glove pattern, upgoing Babinski reflex, and positive Romberg sign being indicative of potential toxicity.
Physical Exam Findings: Upper vs Lower Motor Neuron Lesions

Localize the Lesion- Differential Diagnoses for Extremity Weakness
MRI Findings and Subacute Combined Degeneration
* The MRI displayed symmetric high signal intensity in the dorsal columns, a diagnostic feature identified as the inverted V sign or inverted rabbit ear sign.
* Significance of the Inverted V Sign: This MRI sign is pathognomonic for subacute combined degeneration, indicating it is a distinct marker for this condition.
* T2 Weighted Axial Images: The inverted V sign is observed in T2 weighted axial MRI images, which are used to evaluate the presence and extent of demyelination within the spinal cord.
* Interpretation of Hyperintense Signals: Hyperintense signals on T2 weighted images generally indicate demyelination, where the protective myelin sheath around nerve fibers is damaged or destroyed.
* Anatomical Location: The dorsal columns,Fri, 01 Mar 2024 - 199 - Episode 193: Threatened Abortion

Background
* Defined as vaginal bleeding during early pregnancy (before 20 weeks) with a closed cervical os, no passage of fetal tissue, and IUP on ultrasound
* Occurs in 20-25% of all pregnancies.
Initial Assessment and Management
* Priority is to assess patient stability, establish good IV access, FAST may be helpful in identifying some ruptured ectopics early
* Broad differential diagnosis is crucial to avoid mistaking conditions like ectopic pregnancy for other emergencies.
* Importance of a detailed history and physical examination.
Diagnostic Approach
* Essential tests include HCG level, urinalysis, and possibly CBC + blood type/Rh status.
* Rhogam’s use is well-supported in second and third trimester bleeding; however, data is less robust for first trimester bleeding in preventing sensitization
* Importance of interpreting b-HCG with caution and understanding HCG discriminatory zones.
* Use of ultrasound imaging, both bedside and formal, to assess the pregnancy’s status.
Patient Counseling and Management
* Open and honest communication about the prognosis of threatened abortion.
* Addressing psychosocial aspects, including dispelling guilt and myths, and screening for intimate partner violence and mental health issues.
* Recommendations against bedrest and certain activities
* Lack of evidence supporting restrictions on sexual activity.
* Standard pregnancy guidelines: avoiding smoking, alcohol, drug use, and starting prenatal vitamins.
Follow-up and Precautions
* Adopting a wait-and-see approach for stable patients, with scheduled follow-ups for ultrasounds and beta-HCG tests.
* Educating patients on critical warning signs that require immediate medical attention.
* Emphasizing the importance of returning to the hospital if experiencing significant bleeding or other severe symptoms.
Take Home Points
* Threatened Abortion is defined as Experiencing abdominal pain and/or vaginal bleeding during early pregnancy (before 20 weeks), characterized by a closed cervical os and no expulsion of fetal tissue. In these cases, it is important to assess patient stability promptly.
* Keep your differential broad in these cases. The evaluation will in most cases involve a combination of labs and ultrasound imaging.
* Understand that the Rhogam certainly has a role in second and third trimester vaginal bleeding in the Rh-negative patient, and that there is a dearth of good data on its role in the first trimester – it will ultimately be a decision that is made by you, OBGYN, and the patient.Thu, 01 Feb 2024 - 198 - Episode 192: Syncope in Children

* ACE/ARB
* K+ Sparing diuretics
* NSAIDs
* Digoxin
* SUX – high risks in neuromuscular disease
Lab errors, hemolysis in samples
VBG vs Chem accuracy
When to repeat a hemolyzed sample
2023 study: Of the 145 children with hemolyzed hyperkalemia, 142 (97.9%) had a normal repeat potassium level. Three children (2.1%) had true hyperkalemia: one had known chronic renal failure and was referred to the ED due to concern for electrolyte abnormalities; the other 2 patients had diabetic ketoacidosis (DKA).
Clinical Presentation / eval
Symptomatic vs. Asymptomatic:
“First symptom of hyperkalemia is death”
If severe, ascending muscle weakness → paralysis
Point at which patients experience symptoms depends on chronicity
>7 mEq/L if chronic and can be lower if acute
Hyperkalemia can be a cause of non-specific GI symptoms
EKG Changes:
ECG findings may be the first marker the ER doc gets that something is wrong
Typical changes:
Peaked T-waves, shortened QT
Lengthening of PR interval and QRS duration
Bradycardia / Junctional rhythm
Hyperkalemia can produce bradycardia without other ECG findings

Introduction
* Host: Brian Gilberti, MD
* Guest: Catherine Jamin, MD
* Associate professor of Emergency Medicine at NYU Langone Health
* Vice Chair of Operations
* Triple-boarded in Emergency Medicine, Internal Medicine, and Critical Care Medicine
* Topic: Vasopressors: Essential agents for supporting critically ill patients in the ED
What Are Vasopressors and When to Use Them
* Two primary mechanisms to increase blood pressure:
* Increasing systemic vascular resistance via vasoconstriction
* Increasing cardiac output via augmenting inotropy and chronotropy
* Indicators for vasopressor use:
* MAP <65, systolic BP <90, or significant drop from baseline BP
* Signs of organ dysfunction like altered mental status, decreased urine output, elevated lactate
* Fluid resuscitation either ineffective or contraindicated (e.g., in CHF patients)
Commonly Used Vasopressors in the ED
* Norepinephrine
* Epinephrine
* Vasopressin
* Phenylephrine
Norepinephrine
* Mechanism: Stimulates alpha-1 (vasoconstriction) and beta-1 receptors (increases inotropy & chronotropy)
* Starting Dose: 10 mcg/min, titrate to MAP >65
* Max Dose: No strict limit but usually add a 2nd pressor at 15-20 mcg/min
* Situational Preference: First-line for most cases of shock (septic, undifferentiated, hypovolemic, cardiogenic)
* Pros: Can be infused peripherally via large bore IV
Vasopressin
* Mechanism: Activates V1a receptors causing vasoconstriction
* Dose: Fixed, non-titratable dose of 0.04 units/min
* Situational Preference: Second-line in septic shock
* Concerns: Potential for peripheral ischemia
Phenylephrine
* Mechanism: Stimulates alpha-1 receptors causing vasoconstriction
* Starting Dose: 100 mcg/min, titrate to MAP >65
* Situational Preference: High cardiac output states, tachyarrhythmias, peri-intubation
* Concerns: Increases afterload, can worsen low cardiac output states
Epinephrine
* Mechanism: Stimulates alpha-1, beta-1 and beta-2 receptors
* Starting Dose: 5-10 mcg/min, titrate to MAP >65
* Situational Preference: Anaphylactic shock, septic cardiomyopathy
* Limitations: Can induce tachycardia, may elevate lactate levels
Escalation Strategy in Refractory Shock
* Norepinephrine -> Vasopressin (with stress dose steroids) -> Epinephrine
* Consider POCUS, lactate, central venous saturation, and acid-base status

General
Pain in joint for pediatric patient has a broad differential, including transient synovitis and septic arthritis
Transient synovitis, also known as toxic synovitis, is a common condition affecting kids aged 3-10 and often occurs after a viral infection. It is typically self-limiting and not considered a serious condition.
Septic arthritis is an infection in the joint space, typically affecting only one joint. It is often difficult to diagnose due to the fact that many patients, particularly under the age of 3, may not be able to localize their pain to a specific joint.
Workup
Diagnostic work-up for septic arthritis begins with blood work, which includes a complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and blood cultures. Lyme disease studies may also be necessary since Lyme disease can cause joint pain.
Patients with transient synovitis typically have mild elevation in inflammatory markers, while those with septic arthritis usually show a significant elevation.
Imaging studies, including X-rays, ultrasound to evaluate for a joint effusion, and MRI to assess for associated osteomyelitis, are also part of the diagnostic approach.
The Kocher criteria, developed specifically for septic arthritis of the hip, are a useful tool for clinical decision-making. The criteria include fever above 38.5 C, inability to bear weight, ESR above 40, and a white blood cell count above 12,000.
1 criterion met = 3% probability of septic arthritis
2 criteria met = 40% probability of septic arthritis
3 criteria met = 93% probability of septic arthritis
4 criteria met = 99+% probability of septic arthritis
If septic arthritis is suspected, orthopedics should be consulted immediately. Joint fluid aspiration is necessary for diagnosis and should not be delayed. The fluid should be sent for cell count, gram stain, glucose, culture, and PCR if available.
Septic arthritis is most commonly caused by bacterial infections, with Staph aureus being the most common organism. In school-age children, other bacteria such as Strep pyogenes, Strep pneumoniae, and Haemophilus influenzae should also be considered. In preschool-aged children, K. kingae is also considered. In older children and neonates, the range of potential bacteria varies.

Congratulations to a wonderful group of physicians. It is a pleasure to recognize your great accomplishments in the presence of your friends, families, loved ones and the residents and faculty who have learned so much from and with you. I would first like to recognize those of you who are members of the Gold Humanism Honor Society.
There are a remarkable number of awardees in our graduating class of 2020.

GOLD HUMANISM CORE VALUES
Integrity, Excellence, Compassion, Altruism, Respect, Empathy, Service
These are the values you want as a doctor for yourself or a loved one,
* to have outstanding listening skills with patients
* to be at your side during a medical emergency,
* to have exceptional interest in service to the community,
* to have the highest standards of professionalism
* to integrate a humanistic approach in patient care.
These values are what brought all of you to NYU-Bellevue and that you have honed throughout your training. The remainder of this talk shows how all of you have been successful and demonstrated these values some of you were elected to the Gold Humanism—all of you have achieved humanistic success.
Your personal efforts in the face of uncertainty of the evolution of the pandemic, the inadequate supplies, the hospital and governmental problematic decisions are remarkable. In our country, the President did not mourn the loss of more than a 100,000 human beings and the needs of society. Nor did he provide the leadership and moral support that the country desperately needed to optimally handle this unprecedented crisis. You, in contrast, demonstrate unflappable commitment to address and overcome obstacles to care for your patients, assist your peers, educate and care for your families and friends, while also caring for yourselves. This is a tribute to your humanism. You created essential ways to help patients who were isolated from families and friends during the critical phases of COVID-19.Tue, 30 Jun 2020 - 5min - 183 - Episode 177.0 – Hemoptysis

Show Notes
Overview
Blunt neck trauma comprises 5% of all neck trauma
Mortality due to loss of airway more so than hemorrhage
Mechanism
MVCs with cervical hyperextension, flexion, rotation during rapid deceleration, direct impact
Strangulation: hanging, choking, clothesline injury (see section on strangulation in this chapter)
Direct blows: assault, sports, falls
Initial Management/Primary Survey
Airway
Evaluate for airway distress (stridor, hoarseness, dysphonia, dyspnea) or impending airway compromise
Early aggressive airway control: low threshold for intubation if unconscious patient, evidence of airway compromise including voice change, dyspnea, neurological changes, or pulmonary edema
Assume a difficult airway
* Breathing
Supplemental oxygen
Assess for bilateral breath sounds
Can use bedside US to evaluate for pneumothorax or hemothorax
* Circulation
Assess for open wounds, bleeding, hemorrhage
IV access
* Disability
Maintain C-spine immobilization
Calculate GCS
Look for seatbelt sign
Secondary Survey
Evaluate for specific signs of vascular, laryngotracheal, pharyngoesophageal, and cervical spinal injuries with inspection, palpation, and auscultation
Perform extremely thorough exam to evaluate for any concomitant injuries (e.g. stab wounds, gunshot wounds, intoxications/ ingestions, etc.)
Types of Injuries
Vascular injury
Overview
Carotid arteries (internal, external, common carotid) and vertebral arteries injured
Mortality rate ~60% for symptomatic blunt cerebral vascular injury
Mechanism
Hyperextension and lateral rotation of the neck, direct blunt force, strangulation, seat belt injuries, and chiropractic manipulation
Morbidity due to intimal dissections, thromboses, pseudoaneurysms, fistulas, and transections
Clinical Features
Most patients are asymptomatic and do not develop focal neurological deficits for days
if Horner’s syndrome, suspect disruption of thoracic sympathetic chain (wraps around carotid artery)
specific screening criteria are used to detect blunt cerebrovascular injury in asymptomatic patients (see below)

Background
* Among most common injuries evaluated in ED
* A sprain is an injury to 1 or more ligaments about the ankle joint
* Highest rate among teenagers and young adults
* Higher incidence among women than men
* Almost a half are sustained during sports
* Greatest risk factor is a history of prior ankle sprain
Anatomy
* Bone: Distal tibia and fibula over the talus → constitutes the ankle mortise
* Aside from malleoli, ligament complexes hold joint together
* Medial deltoid ligament
* Lateral ligament complex
* Anterior talofibular ligament
* Most commonly injured
* Weakest
* 85% of all ankle sprains
* Posterior talofibular ligament
* Calcaneofibular ligament
* Syndesmosis
Mechanism of Injury
* Lateral ankle sprains
* Most common among athletes
* ATFL most commonly injured
* Combined with CFL in 20% of injuries
* 2/2 inversion injuries
* Medial ankle sprains
* Less common than lateral because ligaments stronger and mechanism less frequent
* More likely to suffer avulsion fracture of medial malleolus than injure medial ligament
* 2/2 eversion +/- forced external rotation
* Typically landing on pronated foot -> external rotation
* High Ankle sprains
* Syndesmotic injury
* More common in collision sports (football, soccer, etc)
* Grade I
* Mild
* Stretch without “macroscopic” tearing
* Minimal swelling / tenderness
* No instability
* No disability associated with injury
* Grade II
* Moderate
* Partial tear of ligament
* Moderate swelling / tenderness
* Some instability and loss of ROM
* Difficulty ambulating / bearing weight
* Grade III
* Severe
* Complete rupture of ligaments
* Extensive swelling / ecchymosis / tenderness
* Mechanical instability on exam
* Inability to bear weight
Examination
* Beyond visual inspection for swelling, ecchymoses, abrasions, or lacerations
* Palpation
* Pain when palpating ligament is poorly specific but may indicate injury to structure
* Check sites for Ottawa ankle rules to evaluate if there may be an associated fracture with injury
* Posterior edge or tip of lateral malleolus (6 cm)
* Posterior edger or tip of medial malleolus (6 ...Mon, 04 Nov 2019 - 11min - 177 - Episode 171.0 – Vaping Associated Lung Injury

Why this matters
As of Oct 15, vaping has been associated with acute lung injury in over 1400 people
33 deaths have been confirmed in 24 states
70+% of those with VALI are young men
A large number of patients are requiring ICU/ intubation/ ECMO
4 main ingredients in solvent
+/- Flavor additives
+/- Nicotine or THC (Tetrahydrocannabinol)
Propylene Glycol (PG)
Vegetable Glycerin (VG)
CDC definition of VALI (Vaping Associated Lung Injury)
Using an e-cigarette (“vaping”) or dabbing* in 90 days prior to symptom onset AND
Pulmonary infiltrate, such as opacities, on plain film chest radiograph or ground-glass opacities on chest CT AND
Absence of pulmonary infection on initial work-up.
No evidence in the medical record of alternative plausible diagnoses (e.g., cardiac, rheumatologic, or neoplastic process).
*Dabbing allows the user to ingest a high concentration of THC. Butane Hash Oil (BHO), an oil or wax-like substance extracted from the marijuana plant, is placed on a “nail” attached to a specialized glass bong called a “rig.” A blow torch is used to heat the wax, which produces a vapor that can then be inhaled to supposedly produce an instantaneous effect.
Pathophysiology
At present, no single compound or ingredient has emerged as the cause, and there may be more than one cause
The only common thread among the cases is that ALL patients reported using e-cig or vaping products
Leading potential toxins:
Vaping products containing THC concentrates: most cases are linked to THC concentrates that were either purchased on the street or from other informal sources (meaning not from a dispensary)
Vitamin E acetate: nutritional supplement safe when ingested or applied to the skin (but likely not when inhaled) has been found in nearly all product samples of NY state cases of suspected VALI
vitamin E acetate is NOT an approved additive at least by NYS Medical Marijuana program
Other potential toxins:
IT CANNOT BE UNDERSTATED that a small percentage of persons w/ VALI have reported exclusive use of nicotine-containing vape products, such as JUUL; as such, we must consider the potential toxicity of standard e-liquid or vape juice
Flavor additives, that exists as chemical aldehydes: irritating and potentially damaging to lung tissue

Episode Produced by Audrey Bree Tse, MD
Background
Bacteria enters the joint by hematogenous spread due to absence of basement membrane in synovial space from invasive procedures, contiguous infection (e.g. osteomyelitis, cellulitis), or direct inoculation (e.g. plant thorns, nails)
WBCs migrate into joint → acute inflammatory process → synovial hyperplasia, prevents new cartilage from forming, pressure necrosis on surrounding joint, purulent effusion
Why do we care?
irreversible loss of function in up to 10% & mortality rate as high as 11%
Cartilage destruction can occur in a matter of hours
Complications include bacteremia, sepsis, and endocarditis
Etiology
Risk factors: extremes of age, RA, DJD, IVDA, endocarditis, GC, immunosuppression, trauma, or prosthesis
Organisms:
Staph: staph aureus (most common), MRSA, Staph epidermis
N gonorrhea: young healthy sexually active adults
Strep: group A & B
GNRs: IVDA, diabetics, elderly
Salmonella: sickle cell disease
Cutibacterium acnes: prosthetic shoulder infection
Consider mycobacterial & fungal in more indolent courses
Presentation
Typically a single, warm, erythematous, tender joint (#1: knee (50% of cases) → hip, shoulder, ankle)
*Any joint can be involved!
IVDA can involve sacroiliac, costochondral, & sternoclavicular joints
Classic teaching: very painful with ROM, but this is not always present!
Joint usually held in position of maximum joint volume
Prosthetic joints may have less pain than expected for a septic joint given changed anatomy and disrupted nerve endings
In 10-20% of cases, can see polyarticular involvement
GC typically monoarticular but commonly polyarticular
Often have fever & separate infection as well (only see fever in ~60% of cases)
Diagnostics
Arthrocentesis:
Gold standard
Tap joint even if acceptable ROM: septic joints can have normal motion so it does not exclude the diagnosis!
Use ultrasound if possible
Relative contraindications: overlying cellulitis (risk of seeding joint) or severe coagulopathies (weigh risk of creation or worsening of iatrogenic hemarthrosis)
Keep in mind that a “dry tap” may occur due to incorrect needle placement, absent/ minimal joint effusion, ort mechanical obstruction
Note: talk to ortho colleagues if prosthesis present prior to performing arthrocentesis

Background
* The most common type of seizure in children under 5 years of age
* Occur in 2-5% of children
* In children with a fever, aged 6 months to 5 years of age, and without a CNS infection
* Risk Factors
* 4 times more likely to have a febrile seizure if parent had one
* Also increase in risk if siblings or nieces / nephews had one
* Common associated infections
* Human Herpesvirus 6
* Human Herpesvirus 7
* Influenza A & B
* Simple Febrile Seizure
* Generalized tonic-clonic activity lasting less than 15 minutes in a child 6 months to 5 years of age
* Complex Febrile Seizure
* Lasts longer than 15 minutes, occurs in a child outside of this age range, are focal, or that recur within a 24-hour period.
Diagnostics / Workup
* Gather thorough history and perform thorough physical exam
* Most cases will not require labs, imaging or EEG
* If e/o meningitis, perform LP
* AAP suggests considering LP in:
* Children 6-12 months who are not immunized for H flu type B or strep pneumo
* Children who had been on antibiotics
* For complex seizures, clinician may have a lower threshold for obtaining labs
* Hyponatremia is more common in this group than in the general population.
* LPs are more commonly done by providers, but these are low yield with one study showing bacterial meningitis being diagnosed in just 0.9% (Kimia 2010), all of whom did not have a normal exam or negative cultures.
* Neuroimaging is also exceedingly low yield if the patient returns to baseline (Teng 2006)
* One study that showed that the duration of complex febrile seizure, being greater than 30 minutes, was associated with a higher incidence of bacterial meningitis. (Chin 2005)
* Of they have history and exam concerning for meningitis, they should get an LP
* If they look dehydrated or edematous, you would have more of a reason to get a chemistry
Treatment
* Benzodiazepine if seizure lasted for >5 minutes, either IV or IN
* Supportive care
* Tylenol or motrin if febrile
* Fluids if signs of dehydration
* Antipyretics “around the clock”
* A majority of data show no benefit in preventing recurrence of seizure
* One study (Murata 2018) found that giving tylenol q6h at 10 mg/kg for the first 24 hours following the initial seizure decreased the rate of recurrence when compared to children who did not receive antipyretics.

Background
* Most common tick-born illness in North America
* Endemic in Northeast, Upper Midwest, northwest California
* 80% to 90% in summer months
Pathophysiology
* Ixodes tick (deer tick) has a 3-stage life cycle (larvae, nymph, adult) & takes 1 blood meal per stage
* Deer tick feeds on an infected wild animal (infected with spirochete Borrelia burgodrferi) then bites humans
* On humans, they typically move until they encounter resistance (e.g. hairline, waistband, elastic, skin fold). It takes 24-48 hrs for B. Burgdorferi to move from the tick to the host
* Pathogenesis: organism induced local inflammation, cytokine release, autoimmunity
* No person to person transmission
Clinical Presentation
Stage 1: Early
* Symptom onset few days to a month after tick bite
* Erythema migrans rash: bulls eye rash seen in more than 90% of patients with Lyme disease (Irregular expanding annular lesion(s))
* Regional adenopathy, intermittent fevers, headache, myalgias, arthralgia, fatigue, malaise
Stage 2: disseminated/ secondary
* Days to weeks after tick bite
* Intermittent fluctuating sx that eventually resolve
* Triad of aseptic meningitis, cranial neuritis, and radiculoneuritis: bell palsy most common
* Cardiac symptoms: tachycardia, bradycardia, AV block, myopericarditis
Stage 3: tertiary/ late
* Symptoms occur >1 year after tick bite
* Acrodermatitis chronic atrophicans: Atrophic lesions on extensor surfaces of extremities (resembles scleroderma)
* Monoarthritis, oligoarthritis (knee > shoulder > elbow)
* GI: Hepatitis, RUQ pain
* Ocular: keratitis, uveitis, iritis, optic neuritis
* Neurological: Chronic axonal polyneuropathy or encephalopathy
Chronic Lyme disease (versus well-accepted Lyme disease sequelae):
* Continuation of symptoms after antibiotics
* Current recommendation for management is supportive care only
Pediatric considerations:
* More likely to be febrile than adults
* Facial palsy accompanied by aseptic meningitis in 1/3
* Untreated kids can develop keratitis
* Excellent prognosis if appropriately treated
History
* Travel, camping, woods, playing under leaves or in wood piles
* Living in endemic area (Northeastern area: Maine to Virginia; upper Midwestern: Wisconsin, Minnesota; Northwest California)
* Endemic in Northern Europe and Eastern Asia as well
* History of tick bite (- 30-50% of patients recall tick bite)Tue, 30 Jul 2019 - 15min - 173 - Episode 167.0 – Malaria

Background
* In 2017, there were 219 million cases and 435,000 people deaths from malaria
* Five species: Falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi.
* Falciparum, Vivax and Knowlesi can be fatal
* History of recent travel to Africa (69% of cases in US), particularly to west-Africa should raise suspicion for malaria
Clinical Manifestations
* Average incubation period for Falciparum is 12 days
* 95% will develop symptoms within 1 month
* Clinical findings with high likelihood ratios include periodic fevers, jaundice, splenomegaly, pallor.
* Can also have vomiting, headache, chills, abdominal pain, cough, and diarrhea
* Severe malaria has a mortality of 5% to 30%, even with therapy
* Diagnostic criteria for severe malaria:
Ashley 2018
* Most common manifestations of severe malaria affect the brain, lungs, and kidneys
* Patients with cerebral malaria can present encephalopathic or comatose, some severe enough to exhibit extensor posturing, or seizures
* Can have acute lung injury with a quarter of these patients progressing to ARDS
* Can have AKI from ATN and resultant acidosis
* Labs may be unremarkable but watch for anemia and thrombocytopenia
* Hgb <5 has an OR = 4.9 for death
* Severe thrombocytopenia has an OR = 2.8
* Anemia + Thrombocytopenia has an OR = 13.8 (Lampah 2015, PMID25170106)
* Watch for hypoglycemia
* Be mindful of co-infection with salmonella and HIV
* Obtain BCx, cover with ceftriaxone
Diagnosis
* Blood smear
* Thick smear to increase sensitivity for detecting parasites
* Thin smear for quantifying parasitemia and species
* The first smear is positive in over 90% of cases, but if suspicion is high, it has to be repeated BID for 2-3 days for proper exclusion of malaria (CDC 2019)
Management
* For uncomplicated, non-severe cases, most patients with falciparum should be admitted, especially those with no prior exposure to malaria parasites
* Malarone is one of the first line options
* Check out other suggested regimens from the CDC
* Important to note that when they take this, ensure they take with milk or food containing fat to enhance absorption
* Severe Malaria

Background:
* The most common infection seen in pediatrics and the most common reason these kids receive antibiotics
* The release of the PCV (pneumococcal conjugate vaccine), or Prevnar vaccine, has made a big difference since its release in 2000 (Marom 2014)
* This, along with more stringent criteria for what we are calling AOM, has led to a significant decrease in the number of cases seen since then
* 29% reduction in AOM caused by all pneumococcal serotypes among children who received PCV7 before 24 months of age
* The peak incidence is between 6 and 18 months of age
* Risk factors: winter season, genetic predisposition, day care, low socioeconomic status, males, reduced duration of or no breast feeding, and exposure to tobacco smoke.
* The predominant organisms: Streptococcus pneumoniae, non-typable Haemophilus influenzae (NTHi), and Moraxella catarrhalis.
* Prevalence rates of infections due to Streptococcus pneumoniae are declining due to widespread use of the Prevnar vaccine while the proportion of Moraxella and NTHi infection increases with NTHi now the most common causative bacterium
* Strep pneumo is associated with more severe illness, like worse fevers, otalgia and also increased incidence of complications like mastoiditis.
Diagnosis
* The diagnosis of acute otitis media is a clinical one without a gold standard in the ED (tympanocentesis)
* Ear pain (+LR 3.0-7.3), or in the preverbal child, ear-tugging or rubbing is going to be the most common symptom but far from universally present in children. Parents may also report fevers, excessive crying, decreased activity, and difficulty sleeping.
* Challenging especially in the younger patient, whose symptoms may be non-specific and exam is difficult
* Important to keep in mind that otitis media with effusion, which does not require antibiotics, can masquerade as AOM
AAP: Diagnosis of Acute Otitis Media (2013)*
* In 2013, the AAP came out with a paper to help guide the diagnosis of AOM
* Moderate-Severe bulging of the tympanic membrane or new-onset otorrhea not due to acute otitis externa (grade B)
* The presence of bulging is a specific sign and will help us distinguish between AOM and OME, the latter has opacification of the tympanic membrane or air-fluid level without bulging (Shaikh 2012, with algorithm)
* Bulging of the TM is the most important feature and one systematic review found that its presence had an adjusted LR of 51 (Rothman 2003)
* Classic triad is bulging along with impaired mobility and redness or cloudiness of TM

Episode Produced by Audrey Bree Tse, MD
Background:
* Why do we care about Jones fractures?
* Propensity for poor healing due to watershed area of blood supply
* Fifth metatarsal fractures account for 68% of metatarsal fractures in adults
* Proximal 5th metatarsal fractures are divided into 3 zones (93% zone 1, 4% zone 2, 3% zone 3)
* Zone 1 (pseudo-Jones):
* Tuberosity avulsion fracture
* Typically avulsion type injuries due to acute episode of forefoot supination with plantar flexion
* Typical fracture pattern is transverse to slightly oblique
* Zone 2 (Jones fracture):
* Fracture at the metaphyseal-diaphyseal junction of the fifth metatarsal
* Typically acute episode of large adduction force applied to forefoot with the ankle plantar flexed
* Zone 3:
* Proximal diaphyseal stress fracture
* Typically results from a fatigue or stress mechanism
Clinical Presentation:
* History of acute or repetitive trauma to forefoot
* Fracture type / pattern closely related to injury location
* Foot often swollen, ecchymotic, very tender to fifth metatarsal +/- crepitus, inability to hear weight
Diagnosis:
* Clinical exam:
* Evaluate skin integrity
* Check neurovascular status
* Evaluate toes/ feet/ ankles/ tib fib/ knees/ hips, involved tendon function, associated adjacent structures (Achilles, ankle ROM/ function, etc)
* 3 XR views: lateral, anteroposterior, 45* oblique
* Acute stress fractures are typically not detected on the standard 3 views; therefore, repeat XRs 10-14d after onset of sx (may see radiolucent reabsorption gap around fracture)
* For more complex mid foot trauma, consider CT to r/o Lisfranc
Treatment:
* Consider classification of fracture, patient demographics & activity level when deciding on treatment
* Tertiary care centers that have access to Orthopedics/Podiatry services
* Consider consultation for “true” Jones fractures, as some cases may be operatively managed acutely and/or for expedited follow-up to be arranged
* If working in community/rural locations: other than patients that present with “open” injuries, concerns for compartment syndrome (almost never), and “high-end”/professional athletes, there are generally no other circumstances that would require expedited transfer to a tertiary care center for immediate further evaluation.
* Less favorable outcomes associated with certain patient factors: female gender, DM, obesity

TAKE HOME POINTS
* Debriefing after a clinical case in the ED is a way to have an interprofessional, reflective conversation with a focus on improving for the next patient. We can debrief routine cases, challenging cases, or even cases that go well.
* Follow a structure when leading a debrief.
* The prebrief sets ground rules and informs the team that the debrief is optional and will only take 3-5 minutes.
* Introduce names and roles
* Then give a one-liner about what happened in the case, followed by a plus/ delta: address what went well and why, then how to improve
* Finally, wrap up with take home points
* Pitfalls to watch out for in clinical debriefing include:
* Avoid siloing or alienating any learners. Learn from all your colleagues on your team- it’s less about medicine and more about interprofessional and systems issues
* Don’t pick on individual performance. It’s not about shaming- it’s about improving patient care
* Avoid “guess what I’m thinking” questions; ask real questions
* Proceed with caution in order to dampen or avoid psychological trauma and second victim syndrome. The learner may ask “was this my fault?”; we never want a learner to feel this way. Ask, what systems supported or did not support you today? Talk about what happened. Avoid shame and blame.
* Have the right values and do it for the right reasons.

* Rash with dysuria should raise concern for SJS with associated urethritis
* Dysuria present in a majority of cases
* SJS is a mucocutaneous reaction caused by Type IV hypersensitivity
* Cytotoxic t-lymphocytes apoptose keratinocytes → blistering, bullae formation, and sloughing of the detached skin
* Disease spectrum
* SJS = <10% TBSA
* TEN = >30% TBSA
* SJS/ TEN Overlap = 10-30% TBSA
* Incidence is estimated at around 9 per 1 million people in the US
* Mortality is 10% for SJS and 30-50% for TEN
* Mainly 2/2 sepsis and end organ dysfunction.
* SJS can occur even without a precipitating medication
* Infection can set it off especially in patients with risk factors including HIV, lupus, underlying malignancy, and genetic factors
* SATAN for the most common drugs
* Sulfa, Allopurinol, Tetracyclines, Anticonvulsants, and NSAIDS
* Anti-epileptics include carbamazepine, lamictal, phenobarb, and phenytoin
* Can have a curious course
* Hypersensitivity reaction can develop while taking medication, or even one to four weeks after exposure
* In pediatric population, mycoplasma pneumonia and herpes simplex have been identified as precipitating infections
* Patients often have a prodrome 1-3 days prior to the skin lesions appearing
* May complain of fever, myalgias, headaches, URI symptoms, and malaise
* Rash may be the sole complaint
* Starts as dark purple or erythematous lesions with purpuric centers that progress to bullae
* Skin surrounding the lesions detaches from the dermis with just light pressure (Nikolsky Sign)
* Up to 95% of patients will have mucous membrane lesions
* ~85% will have conjunctival lesions
* Symptoms: Burning or itching eyes, a cough or sore throat, pain with eating, pain with urinating or defecating
Source: JAMA Dermatol. 2017
* Differential Diagnosis: SSSS, autoimmune bullous diseases, bullous fixed drug eruption, erythema multiforme, thermal burns, phototoxic reactions, and TSS
* SJS is a clinical diagnosis
* Basic workup: CBC, chemistry panel, LFTs, and a UA
* Treatment
* Supportive care
* IV fluid repletion guided by TBSA affected, as well as electrolyte, protein, and energy supplementation

* Subdissociative ketamine
* Nerve blocks
* Curb misuse and diversion through prescribing a short supply and perform I-STOP checks
* Narcan is not just for acute overdose treatment by EMS or within the ED anymore
* We can equip patients, family members and friends with Narcan kits prior to discharge
* In New York state, can prescribe Narcan to patients with near fatal overdoses or who screen positive for an opioid use disorder
* Intranasal formulation is cheaper and more commonly prescribed than IM
* Buprenorphine induction can be done in the ED for patients in active withdrawal, as calculated by the COWS score.
* MDcalc calculator: https://www.mdcalc.com/cows-score-opiate-withdrawal
* Providers do not need an X-waiver to give a dose of Buprenorphine in the ED for 3 days
* Home induction can be considered for patients not actively withdrawing but would like to enter medication assisted treatment
* Some considerations:
* Contraindicated in patients with severe liver dysfunction and with hypersensitivity reaction to drug
* Oversedation can occur with concurrent use of benzodiazepines and alcohol
* Will precipitate withdrawal if concurrently using full opioid agonists
* Longitudinal care has to be established for patients started on Buprenorphine

Background:
* 40% of all hand fractures
* A metacarpal fracture can occur at any point along the bone (head, neck, shaft, or base)
* “Boxer’s” fractures classically at neck
* Most common mechanism: direct axial load with a clenched fist
* Most common metacarpal injured is the 5th
* A majority of these injuries are isolated injuries, closed and stable
Examination:
* Ensure that this is an isolated injury
* May note a loss of knuckle contour or shortening
* A thorough evaluation of the skin is important
* Patients may also have fight bites and require irrigation and antibiotics
* Tender along the dorsum of the affected metacarpal
* Evaluate the range of motion as the commonly seen shortening results in extension lag
* For every 2 mm of shortening there is going to be a 7 degree decrease in ability to extend the joint
* Check rotational alignment of digits with the MCP and PIP at 50% flexion.
* Partially clench their fist and ensure that the axis of each digit converges near the scaphoid pole / mid wrist
* Deformity is often seen due to the imbalance of volar and dorsal forces
* Dorsal angulation
* AP, lateral and oblique views should be obtained on XR
* The degree of angulation is estimated with the lateral view
* NB: Normal angle between the metacarpal head and neck is 15 degrees
Management:
* Most may be splinted with an ulnar gutter splint
* Must be closed, not significantly angulated, and not malrotated
* When splinting, place the wrist in slight extension, MCP (knuckles) at 90 degrees and the DIP and PIP in a relaxed, slightly flexed position
* A closed reduction is indicated if there is significant angulation
* “20, 30, 40” rule
* If angulation is more than:
* 20 in the middle finger metacarpal
* 30 in the ring finger metacarpal
* 40 in the pinky finger metacarpal
* Analgesia with a hematoma block or ulnar nerve block
* Reduction technique: https://www.aliem.com/2013/01/trick-of-trade-reducing-metacarpal/

Cauda equina syndrome is a rare emergency with devastating consequences
Early recognition is paramount as the presence of bladder dysfunction portends bad functional outcomes
The presence of bilateral lower extremity weakness or sensory changes should alert clinicians to the diagnosis. Saddle anesthesia (or change in sensation) and any bladder/bowel changes in function should also raise suspicion for the disorder
MRI is the diagnostic modality of choice though CT myelogram can be performed if necessary
Prompt surgical consultation is mandatory for all patients with cauda equina syndrome regardless of symptoms at presentation

While peds traumas and severe traumas are uncommon, stay cool and collected – you’ve run many resuscitations in the past and resuscitating a kid is no different. You’ve got this
When it comes to access, think 1, 2 IO. 2 shots at a peripheral line and if you don’t get it, go to IO
Tachycardia should be assumed to be compensated shock until proven otherwise. Don’t write tachycardia off as anxiety
Failed airway approach – place an 18 gauge catheter into the neck – hopefully through the cricothyroid membrane and bag through that. If you still have difficult getting an airway from above, consider a retrograde intubation over a wire

The PERC risk stratifies low risk PE patients (~10%) to a level low enough (1.9%) as to obviate the need for additional testing.
Age-adjusted D-dimers are ready for use and it doesn’t matter if your assay uses FEU (cutoff 500) or DDU (cutoff 250). For FEU use an upper limit of 10 X age and for DDU use an upper limit of 5 X age.
For now, subsegmental PEs should continue to routinely be anticoagulated even in the absence of a DVT. Keep an eye out for more research on this area.
Although outpatient management of select PE patients (using sPESI or Hestia criteria) may be standard practice, the evidence wasn’t strong enough for ACEP to give it’s support
Patients with DVT can be started on a NOAC and discharged from the ED

Always consider salicylate toxicity:
In patients with tachypnea, hyperpnea, AMS and clear lungs
In the presence of an anion gap metabolic acidosis with a respiratory alkalosis
Treat salicylate toxicity by alkalinizing the blood and urine to increase excretion
Avoid intubation until absolutely necessary. If you do have to intubate, minimize apneic time and consider awake intubation and nake sure your ventilator settings match the patient’s necessary high minute ventilation
Think about chronic salicylate toxicity in unexplained altered mental status, tachypnea or metabolic acidosis in elderly
Know indications for hemodialysis in salicylate toxic patients

In patients with neck pain, consider Ludwig’s angina particularly if they have any swelling, fever, truisms or respiratory difficulty. Consider early airway management and get your consultants involved early for operative management
Endocarditis is a tricky diagnosis and will often be subtle. Any patient with a prosthetic valve and a fever has endocarditis until proven otherwise. Suspect it in any patient with fever and a murmur, get lots of cultures and remember that TEE is the gold standard but, TTE is highly specific
Finally, penetrating neck trauma. Patients with hard signs – airway compromise, ongoing brisk bleeding, an expanding/pulsatile hematoma, neurologic compromise, shock or hematemesis should go directly to the OR and don’t probe the wounds!

Testicular torsion is a surgical emergency that requires immediate urologic consultation to increase the rate of tissue salvage.
History, physical examination and ultrasound are all flawed in making the diagnosis. The gold standard is surgical exploration
Consider manual detorsion in patients where consultation will be delayed

Consider DSI to facilitate pre-oxygenation. Ketamine is your go to drug here
A NCHCT performed within 6 hours of symptom onset is extremely sensitive for ruling out SAH but, nothing is 100%. If you’ve got a high-risk patient, you should still consider LP
Patients with caustic ingestions can have rapidly deteriorating airways. Prepare early and be ready to take over the airway at a moments notice

Show Notes
Summary: Based on the limited available evidence, it’s unlikely orthostatic vital sign measurement can be used to determine which patients have volume loss and which do not. The baseline prevalence of orthostatic vital signs is common and patients will not always develop orthostatic vital signs in response to volume loss. Therefore, there will both be patients who are orthostatic by numbers without volume loss and there will be patients with volume loss who are not orthostatic by numbers. Symptoms, with the exception of inability to stand to have orthostatics performed, are not useful either.
Bottom Line: Based on the low overall sensitivity of orthostatic vital sign measurements, they should not be used to influence clinical decision making.

2. In kids with AMS, think of zebra diagnoses and toxic ingestions and remember that primary psychosis is rare
3. Patients with ALL are susceptible to developing hyperleukocytosis. If the WBC is > 100K, think about getting hematology on the line to initiate chemo induction and leukopheresis
4. Always think about electrolyte disorders, particularly hypoNa in patients with global AMS. Remember to treat severe hypoNa w/ hypertonic saline and, to correct slowly as to avoid ODS

Air embolism is a rare but potentially fatal complication of central line placement and some surgical procedures and of course of as the result of barotrauma.
Recognizing the signs and symptoms of air embolism can be tricky because it will look like any other ischemic process. Consider air embolism if you have a patient that rapidly decompensates after placement of a central line, the most likely culprit for those of us in the ED.
Treatment should focus on supportive cares. Give supplemental O2, IV fluids and hemodynamic support and consider hyperbarics and cardiopulmonary bypass for the super sick patient.

SBP is a difficult diagnosis to make because presentations are variable. Consider a diagnostic paracentesis in all patients presenting to the ED with ascites from cirrhosis
An ascites PMN count > 250 cells/mm3 is diagnostic of SBP but treatment should be considered in any patient with ascites and abdominal pain or fever
Treatment of SBP is with a 3rd generation cephalosporin with the addition of albumin infusion in any patient meeting AASLD criteria (Cr > 1.0 mg/dL, BUN > 30 mg/dL or Total bilirubin > 4 mg/dL)

Keep IIH and CVST on the differential for patient’s coming in with a subacute headache, particularly if they have visual or neuro symptoms.
Consider an ocular ultrasound! It’s quick, shockingly easy to do, and can help point you toward a diagnosis you may have otherwise overlooked. I have made it my practice now to include a quick look in the physical exam of my patients with a concerning sounding headache or a headache with neurologic symptoms.
Consider IIH particularly in an overweight female of child bearing age with a subacute headache, but remember patients outside that demographic can have IIH as well.
Consider CVST in a patient with a thrombophilic process like cancer, pregnancy or the use of OCPs or androgens or in a patient with a recent facial infection like sinusitis or cellulitis.

SBP is a difficult diagnosis to make clinically. While patients may have the triad of fever, abdominal pain and increasing ascites, they are far more likely to only have 1 or 2 of these symptoms
In patients admitted to the hospital with ascites, consider performing a diagnostic paracentesis on all patients as limited literature shows an association with decreased mortality and, the procedure is simple and low risk
Once you get the fluid, focus on the cell count: WBC > 500 or PMN > 250 should prompt treatment with a 3rd generation cephalosporin and albumin infusion

Up to 50% of true knee dislocations will spontaneously reduce prior to arrival. Be suspicious of a dislocation in any patient who describes the joint moving out of place or if they have significant swelling, joint effusion or ecchymosis despite normal X-rays
In all patients with suspected dislocation, perform a neurovascular exam immediately as popliteal artery injury is common. If they’ve got an absent DP or PT pulse, reduce immediately and get a CT angiogram as quickly as possible to assess for popliteal injuries
If distal pulses are intact, you can either do ABIs and if normal, observe and repeat them or get a CTA. If the ABI is abnormal or the patient had an absent or decreased pulse at any point, get the CTA

The most common bites and stings you will see are by bees and ants. These can present as a local reaction, toxic reaction, anaphylaxis or delayed reaction. For all of these, treat with local wound care and epinephrine for any systemic symptoms.
The brown recluse spider is found in the Midwest and presents as local pain and swelling but carries the risk of a necrotic ulcer
The black widow spider is found all around the US and presents with either localized or generalized muscle cramping, localized sweating and potentially tachycardia and hypertension. Treatment is symptom management with analgesics and benzos.
The bark scorpion usually presents with localized pain and swelling, but particularly in children, may present with a serious systemic presentation including jerking muscle movements, cranial nerve dysfunction, hypersalivation, ataxia and opsoclonus, which is the rapid, involuntary movement of the eyes in all directions. Treatment is supportive cares, but remember to call your poison center to ask about antivenin.

Tachycardia in peds patients at discharge was associated with more revisits but not with more critical interventions. If your workup is reassuring, isolated tachycardia in and of itself shouldn’t change your disposition.
Supplemental O2 is not necessary in the management of AMI patients with an O2 sat > 90% and, may be harmful
Until further study and prospective validation has been performed, we’re not going to recommend embracing the Canadian decision instrument on predicting dysrhythmias after a syncopal event.

Take Home Points
Intra-arrest intubation does not appear to improve outcomes. For most patients, support with BVM, or possibly an LMA, is adequate.
Instead of securing an advanced airway, focus on the two things that clearly make a difference in outcomes – good compressions and defibirillation
Good compressions should be fast and hard and you must minimize interruptions in compressions to minimize interruptions in perfusion
Don’t forget that a great resuscitation requires great preparation. Take whatever time you have to discuss with your team and assign roles.

Airway management is paramount, expect a challenging intubation and consider controlling the airway early
When controlling the airway, consider an awake approach and fiberoptics if available. Always be prepared for the can’t intubate, can’t oxygenate scenario with a double set up.
If the patient has urticaria and pruritus, the process is likely histamine mediated and will respond to typical anaphylaxis treatment
Finally, observe the patient for progression of swelling and don’t forget to stop the inciting medication

Always perform a full pre-PSA evaluation including an airway assessment. Time of last meal shouldn’t delay your sedation based on the best available evidence.
Always do a complete setup including consideration of different agents, dosage calculations, preparation of airway equipment and reversal agents.
PSA serious adverse events are rare but you still must be prepared for them. Careful agent selection and dosing can help prevent issues but, know your outs.
If apnea develops, do some basic maneuvers before you reach for the BVM or laryngoscope. Remember OOPS as in “oops, my patient went apneic.” Oxygen on, pull the mandible forward and sit the patient up. This fixes most issues

Take Home Points
Be prepared to intubate early, the patency of the airway can decline quickly and without warning. If there is any concern for burns to face/neck or smoke inhalation, consider taking control of the airway early.
Review the rule of 9s and the parkland formula to direct your large volume fluid resus. Remember the parkland formula directs you to use 4 mL x %TBSA x weight (kg). Half in the first 8 hours and the second half over the next 16 hours. Given the large volume here it’s probably best to use LR or another balanced solution.
Do a thorough trauma eval to make sure you don’t miss any other injuries and be sure to watch for developing compartment syndrome
And last, consider the need to treat for CO and/or cyanide poisoning. Poor cardiac function, cardiac arrest or a high lactate can be clues to cyanide poisoning and just start 100% O2 while you wait for a co-ox, since CO tox is pretty likely.

The step-by-step approach to managing febrile infants is a reliable decision instrument to identify patients at low risk for invasive bacterial infections. Caution in the group of patients 22-28 days of age.
The LOV-ED study shows an association between employing a lung-protective ventilation strategy in the ED and decreased complications from mechanical ventilation. Best available evidence says that we should embrace this approach in the ED.
Cooling to 33 degrees is no better than cooling to 36 degrees. However, shooting 36 degrees is more difficult than we may have thought. We have to continue to be vigilant about maintaining patients in the target temperature range and avoiding fever.

MetHb –emia occurs as a results of various medications including amyl nitrite, dapsone, nitroprusside, phenazopyridine, sodium nitrite and topical anesthetics like benzocaine
Patients will present with cyanosis, short of breath, fatigue, dizziness, weakness and ultimately CNS depression and death at higher concentrations.
If you have a cyanotic/hypoxic patient that does not respond to supplemental oxygen, be concerned for MetHb and send a co-oximetry panel.
If the level is <25% and the patient is asymptomatic you can observe, but if the level is >25% or the patient is symptomatic, you will treat with the antidote methylene blue given as a bolus of 1-2 mg/kg over 5 minutes
And as always, make sure to call your local poison center to get your toxicologists involved. They can help with dosing, and they are also an important player of the public health component in cases such as these, to make sure this is an isolated incident and we don’t have a repeat of the 11 blue men situation.
