PEDIATRIC Advanced Life Support Neva Batayola, MD Pediatric Critical Care What is PALS all about? Evaluating and recognizing an infant or child with respiratory compromise, circulatory compromise, or cardiac arrest Giving timely and appropriate treatment or interventions Applying effective team dynamics, observing individual roles and responsibilities during pediatric resuscitation Providing optimal post resuscitation management Pediatric Chain of Survival prevention Early CPR EMS Rapid PALS Intergrated Post-cardiac Arrest care Berg, M. D. et al. Circulation 2010;122:S862-S875 BLS: foundation of saving lives Fundamental aspects: immediate recognition of sudden cardiac arrest ( unconsciousness) activation of emergency response system ( call 911 ) early performance of CPR (C A B steps) rapid defibrillation (AED) when appropriate CPR: ABC IS FOR BABIES. NOW IT’S C-A-B! NEW OLD High quality CPR… Chest compressions of appropriate rate and depth. "Push fast": push at a rate of at least 100 compressions per minute. "Push hard": push with sufficient force to depress the chest (at least 1/3 of the AP diameter of the chest or approximately 1½ in. = 4 cm in infants and approximately 2 in. = 5 cm in children) allowing complete recoil of the chest after each compression minimizing interruptions in compressions avoiding excessive ventilation High quality CPR = Effective PALS the cornerstone of a system of care that can optimize outcomes beyond return of spontaneous circulation (ROSC). Return to a prior quality of life and functional state of health is the ultimate goal of a resuscitation system of care.

Recognize shock at time of triage 2. Transfer pt immediately to shock/trauma room and amass resuscitation team 3. Begin Oxygen and establish IV access using 90 sec for peripheral attempts 4. If unsuccessful after 2 peripheral attempts, consider IO 5. Palpate for hepatomegaly; auscultate for rales 10 steps of goal-directed management of pediatric shock 6. If liver is up and if no rales are present, push 20ml/kg boluses of isotonic saline up to 60ml in 5-10min until improved perfusion or liver comes down or patient develops crackles. Give blood if with unresponsive hemorrhagic shock If liver is down, beware of cardiogenic shock. Consider inotropic support ( PGE1 to maintain ductus arteriosus in all neonates) . 7. If CRT>2 sec and/or hypotension persists during fluid resuscitation, begin IO / peripheral Epinephrine 10 steps of goal-directed management of pediatric shock 8. If at risk for adrenal insufficiency give hydrocortisone as bolus (50mg/kg) and then as infusion titrating between 2-50 mg/kg/day 9. If continued shock, intubate and support ventilation mechanically. 10. Direct therapy to goals: CRT < 3sec, normal BP for age, improving shock index.
