In a very disturbing outcome last week, a young woman was found unconscious in her car on Staten Island in New York City. The responding police took her to the nearest ED (SIU Hospital) where the treating physician correctly diagnosed opioid overdose, and administered naloxone. The pt became conscious, and was discharged into police custody 6 hours after receiving IM naloxone and showing "healthy" vitals. She was incarcerated and died a few hours later in jail of an opioid overdose. My initial reaction was that 6 hours is not enough time to be certain that an opioid OD pt is stable and ready for discharge, but after reviewing the scant literature on the subject, I found articles like the one attached (NEJM) stating just that - administer naloxone, wait six hours, if oxygen sats and HR and BP are fine, then discharge. Of course, this presumes many things, predominantly that the pt has ODed on a short-half life opioid like diacetylmorphine (Heroin) and not a long-half-like one like methadone (which could explain the tragic consequences of last week). Conceivably, a pt could OD on a long-half-life opioid, be revived by naloxone, and then die of respiratory depression as bioavailability returned. Does anyone know of any newer (DOI: 10.1056/NEJMra1202561) and more nuanced protocols for the treatment of opioid ODs in the ED?
