I‘m the attending physician in a pediatric trauma room, and my patient, a girl who looks to be about 12, is going into anaphylactic shock. “Do something,” her mother screams. I check the girl’s breathing (sounds funny); I check her pulse (seems OK, but who knows?). To my right is a red cart loaded with assorted medications. A voice behind me tells me to give her a dose of epinephrine. “Is she dying?” I ask.
