Emergency Medicine: Resuscitation, Toxicology, and Procedural Judgment
Core concepts
General emergency medicine for the pediatric candidate emphasizes resuscitation science, rapid stabilization, and safe procedures. Understand shock categories (hypovolemic, distributive/septic, cardiogenic, obstructive) and the initial fluid and vasoactive approach. Know the pediatric sepsis recognition bundle and timely antibiotics. Toxicology questions test toxidrome recognition, decontamination principles, and specific antidotes (e.g., naloxone for opioid, N-acetylcysteine for acetaminophen). Trauma questions test primary survey, recognition of internal injury with subtle signs, and damage-control thinking.
Common traps
A frequent trap is choosing a definitive diagnostic test before stabilizing the patient. Another is missing a subtle presentation-e.g., an intoxicated adolescent or a child with a distracting injury. Watch for questions that reward reassessment after an intervention rather than committing to a single plan. Also be careful with fluid bolus volumes and reassessment to avoid over-resuscitation in cardiac or renal disease.
Worked example
A 4-year-old presents drowsy with pinpoint pupils, bradypnea, and RR 8 after ingesting an unknown pill. This is an opioid toxidrome. Immediate priorities: bag-mask ventilation and airway support, then titrated naloxone with reassessment, because the goal is adequate ventilation, not full arousal. Continue monitoring for recurrent toxicity given variable naloxone half-life. Rule of thumb: in any poisoned or unresponsive child, support airway and breathing before identifying the toxin; antidotes are adjuncts, not substitutes for ventilation.
Exam strategy
Stabilize, then diagnose. Reassess after every intervention. Use toxidromes to narrow differentials and remember antidote dosing is weight-based.
