Cardiac Arrest Flashcards
Describe adequate CPR prior to
placement of a definitive airway
chest compressions at 100/min
30 compressions: 2 BVM breaths
rhythm check every 2 min
What rhythms during cardiac arrest should be defibrillated and at what dose?
Shock VFib or VTach
360J for monophasic
150-200J for biphasic
What medications should be considered for VFib/VTach arrest?
Epinephrine 1mg q3m Amiodarone 300mg x1 Lidocaine 1-1.5mg/kg Magnesium 2g IVP (esp if torsades) Calcium chloride 1amp (esp if possible hyperkalemia) Bicarb (esp if prolonged arrest)
What is the temp goal with Therapeutic Hypothermia?
33 deg C
What are general criteria for Therapeutic Hypothermia after cardiac arrest?
VFib/VTach arrest with ROSC < 60m
consider if PEA with ROSC < 30m
comatose or GCS < 9
MAP >80
What is the appropriate energy level for pediatric cardioversion and defibrillation?
0.5-1 J/kg for cardioversion
2 J/kg for defibrillation
What level of ETCO2 indicates adequate chest compressions during resuscitation?
10-20 mmHg
maintaining level >15 is associated with better outcomes
waveform will abruptly increase with ROSC
What is the appropriate defibrillation dose in children and adults?
Children 2 J/kg and 200 J in adults for the first defibrillation attempt.
What is the dose of intravenous magnesium sulfate for torsade de pointes?
1-2 g IV
Steps of perimortem c-section
No. 10 scalpel, midline vertical incision from sternum to symphyses’.
A small vertical incision should be made through the uterus until amniotic fluid is returned.
Scissors should then be used to extend the incision and deliver the child.
Indication for perimortem c-section
Reported gestational age anywhere near viability, >20 - 26 weeks
fundus at or above the umbilicus + loss of maternal vital signs
Done if no ROSC in first 4 minutes
Does not worsen maternal outcome
What are the five recommended sites for intraosseous placement?
Proximal tibia distal tibia distal femur proximal humerus sternum
