Pediatric Cardiac Arrest
Usually secondary to
respiratory failure or arrest
Most Important Intervention
Adequate
oxygenation, ventilation
Basic Life Support
nAirway
•Head-tilt/chin-lift method
•Big tongue; Forward jaw displacement critical
•Avoid extreme hyperextension
•With possible neck injury, jaw thrust
Basic Life Support
nBreathing
•Look-Listen-Feel
•Limit to volume causing chest rise
•Children usually underventilated!
•Use BVM only if proficient
•Pedi BVM’s should not have pop-off valves
Basic Life Support
nBreathing
•Do NOT use demand valve on children
•Ventilate infants, children every 3 seconds
Basic Life Support
nCirculation
•Infants: brachial
•Children: carotid
Basic Life Support
nCirculation
•Infant chest compressions
–2 fingers
–1 finger width below nipple line
–1/2 - 1 inches
–At least 100/minute
Basic Life Support
nCirculation
•Child chest compressions
–One hand
–Lower half of sternum
–1 - 1.5 inches
–100/minute
Basic Life Support
nCirculation
•Child CPR
–Maintain continuous head tilt with hand on
forehead
–Perform chin lift with other hand while
ventilating

Oxygen Therapy
nInitiate ASAP
nDo not delay BLS to obtain oxygen
Oxygen Therapy
nUse highest possible FiO
2
•No risk in short term100% O
2
nHumidify if possible
•Avoids plugging airways, adjuncts
Endotracheal Intubation
Need to intubate is not same as
need to ventilate!
Endotracheal Intubation
nChildren < 8 years old
•Small tracheal diameter
•Narrow cricoid ring
•Uncuffed tubes
nInfants, small children
•Narrow, soft epiglottis
•Straight blade
Endotracheal Intubation
nAttempts not >30 seconds
nBradycardia: oxygenate, ventilate
Endotracheal Intubation
nAvoid hyperextension
nUse “sniffing position”
nLift up; do not pry back
Endotracheal Intubation
nConfirm placement by:
•Seeing tube go through cords
•Chest rise
•Equal breath sounds
•No sounds over epigastrium
•CO
2
in exhaled air
Endotracheal Intubation
nMark tube at corner of mouth
nAvoid excessive head movement
nFrequently reassess breath sounds
nVentilate to cause gentle chest rise
Endotracheal Intubation
nDrug administration
•Do not delay while attempting IV access
•Dilute with normal saline
•Stop compressions
•Inject through catheter passed beyond ETT
•Follow 10 rapid ventilations
Cricothyrotomy
nSurgical contraindicated in children <12
nNarrowing of trachea at cricoid ring makes
procedure hazardous
nUse needle technique only
Vascular Access
nSame reasons as adults
•Drugs
•Fluids
Scalp Veins
nNo value in cardiac arrest
nUseful in infants < 1 year old for
maintenance fluids, drug route
Scalp Veins
nRubber band for tourniquet
n21, 23 gauge butterfly
nAttach syringe, flush needle before
inserting
Scalp Veins
nPoint needle in direction of blood flow
nLeave syringe attached, inject 1cc saline
after entering vein to check infiltration
Hand, Arm, Foot Veins
n22 gauge catheter for smaller children
nRestrain extremity before attempting
nIncise overlying skin with 19 gauge needle
nFlush needle as with scalp vein technique
External Jugular
nLife-threatening situations only
n22 gauge catheter
nRestrain by wrapping in sheet
nExtend head over end of table, rotate 90
0
nIf vein perforates, do not go to other side
•Risk of paratracheal hematoma, airway
obstruction
Prevention of Fluid Overload
nAvoid using bags over 250cc
nUse mini-drip sets, Volutrols
nFluid resuscitation: 20cc/kg boluses
Intraosseous Cannulation
nPlacement of cannula into long
bone intramedullary canal
(marrow space)
Intraosseous Cannulation
nIndication
•Vascular access required
•Peripheral site cannot be obtained
–In two attempts, or
–After 90 seconds
Defibrillation
nPaddle diameter:
•Infants: 4.5 cm
•Children: 8.0 cm
nLargest paddles that contact entire chest
wall without touching
nIf pediatric paddles unavailable, use adult
paddles with A-P placement
Cardioversion
nNarrow-complex tachycardia, rate > 230
•If hemodynamically stable, transport
•Adenosine may be considered
Cardioversion
nNarrow-complex tachycardia, rate > 230
•If hemodynamically unstable, cardiovert
•If no conversion after two shocks, consider
possibility rhythm is sinus tachycardia
Drug Therapy
nEpinephrine
•Asystole, bradycardia PEA
•Stimulates electrical/mechanical activity
Drug Therapy
nEpinephrine Dosage
•IV or IO: 0.01 mg/kg 1:10,000
•ET: 0.1 mg/kg 1:1000
Drug Therapy
nAtropine
•0.02 mg/kg IV or IO
–Double ET dose
•Minimum dose: 0.1 mg to avoid paradoxical
bradycardia
•Maximum single dose:
–Child: 0.5 mg
–Adolescent: 1mg
Drug Therapy
nMost bradycardias respond to
•Oxygen
•Ventilation
nFor bradycardia 2
o
to hypoxia/ischemia,
preferred first drug is epinephrine
