Podcast 537:  Thoughts on Cardiac Arrest

Contributor:  Don Stader, MD

Educational Pearls:

• High-quality compressions are an essential, and probably one of the most important, part of cardiac arrest 
• Actual evidence for drugs in cardiac arrest included in ACLS are limited, including epinephrine, bicarbonate, amiodarone, etc.
• Early defibrillation for ventricular tachycardia (VT) or ventricular fibrillation (VF) has a plethora of supporting evidence
• Double-sequential defibrillation (nearly simultaneous defibrillation using 2 machines) may be considered for refractory dysrhythmias like VF
• tPA during a cardiac arrest can be considered in the setting of massive PE (although the evidence supporting this practice is poor)
• Ending a cardiac arrest resuscitation is a difficult decision and use of ultrasound may be helpful to assess for meaningful cardiac function/activity
