Retrieval at a tiny rural ED north of us about 15 minutes by air. 15 year old boy found unresponsive at home after complaing of a headache the night before. Head bleeds in 15 year olds are rare, but overdoses on Uncle Billy’s Percocet’s aren’t. He had the highest tylenol level I’ve ever seen, and by the time his liver enzymes were checked, they were already elevated. Beginning anitdotal therapy within 8 hours of any size tyelenol ingestion is nearly 100% effective at preventing lever failure. But with an unknown time of ingestion, the risk of fulminant hepatic failure and death is a real possibility.
