You find a 9-year-old boy to be unresponsive. You shout for help, and after finding that he is not breathing and has no pulse, you and a colleague begin CPR. Another colleague activates the emergency response system, brings the emergency equipment, and places the child on a cardiac monitor/defibrillator, which reveals ventricular tachycardia. You attempt defibrillation at 2 J/kg and give 2 minutes of CPR. The rhythm persists at the second rhythm check, at which point you attempt defibrillation with 4 J/kg. A fourth colleague arrives, starts an IV, and administers 1 dose of epinephrine 0.01 mg/kg. If ventricular fibrillation or pulseless ventricular tachycardia persists after 2 minutes of CPR, you will administer another shock. Which drug and dose should be administered next?
