A 72 year old male is being resuscitated after a witnessed cardiac arrest. One shock was administered approximately one minute ago to treat the rhythm seen below. Attempts to place an IV have failed and an intraosseous access has been established. What is the first appropriate pharmacological intervention?
A. 0.5 mg Atropine, IO B. 1 mg Epinephrine, IO C. 300 mg Amiodarone, IO D. 6 mg Adenosine, IV
Epinephrine is the first medication given in VF/VT arrests as well as for PEA/Asystole arrests. Atropine is only given in symptomatic bradycardias; amiodarone is given to correct refractory VF/VT; and adenosine is used to chemically cardiovert supraventricular tachycardias (SVTs).
