In this episode, we'll talk about a recent article in Annals of Emergency Medicine that has a lot of people talking. This is a study that looked at patients on coumadin (warfarin) who had minor head injuries. The patients were admitted for 24 hours of observation and had a repeat head CT. The study looked at how many patients had bleeding on a repeat head CT and the conclusions were suprising. Should this be our new standard of care?  Maybe but maybe not.
