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

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.

Shock management





Optimizing 02 content of the blood
Improving volume & distribution of
cardiac output
Reducing 02 demand
Correcting metabolic derangements
Identifying and reversing the underlying
cause of shock
10 steps of goal-directed management
of pediatric shock
1. 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.

Hemodynamic Support



Dopamine – 1st line vasopressor for fluid-refractory hypotensive
shock with low SVR (10-20mcg/k/min); increase myocardial
contractility after preload restoration.
Epinephrine – 1st line inotrope for fluid refractory, dopamineresistant nonvasodilatory shock (0.02-1mcg/k/min, to as high as 2-3
mcg/kg/min in severe cases)
Norepinephrine – 1st line pressor agent for fluid refractory,
dopamine-resistant vasodilatory (“warm”, hyperdynamic) shock
(0.03-1.5mcg/k/min)
Phosphodiesterase inhibitors
for catecholamine-refractory low cardiac output and
high SVR
milrinone 50-75 mcg/kg iv loading 60 min
0.375-0.75 mcg/kg/min continuous infusion

increases contractility & improves diastolic function
by decreased degradation of cAMP and increased
intracellular calcium release
Pediatric Critical Care Medicine 2005; 6:195-199
Phosphodiesterase inhibitors
Amiodarone (inodilator)
5 mg/kg iv 30 min
5-10 mcg/kg/min infusion

improves myocardial depression and does not
increase SVR or the metabolic demands of the
heart
Pediatric Critical Care Medicine 2001, 2:24-28

Dobutamine (2-20mcg/kg/min)
not to be used alone in severe shock
increases cardiac contractility and decreases PVR
(afterload)

Vasodilator therapy (Nitroprusside/NTG)
for epinephrine-resistant low CO and elevated SVR,
normal blood pressure (afterload unloader)
may need simultaneous inotropic support
always augment volume (preload)
Vasopressin



Endogenous levels decrease in
vasodilatory shock
potent vasoactive agent in the treatment
of vasodilatory shock in adults and
children
Dose: 0.0005-0.002 U/kg/min
varying doses in studies

Resuscitation = medical expertise and
mastery of skills = multiple tasks
Teamwork divides the tasks while multiplying
the chances of success
