I am a nurse in the ER, who has extensive experience with sedation. In my opinion there was absolutely NO reason for you to be given narcan, if in fact your VS were stable and you were not having respiratory difficulty. It is normal to be a bit sleepy after sedation, but demerol and versed are fairly fast acting and their peak effects should have been long gone. It is the nurses responsibility to monitor your condition until you are awake enough to be D/c'd home. Narcan would have reversed what was left of your demerol, however it's half life is much shorter than that of demerol and thus would only provide effects for a short period of time. It probably would not have affected your vicodin at all. As another post read, I also have never given narcan in a sedation except during the procedure when pt. had resp depression to the point of apnea. (or in heroin OD pt's). I'm sorry that you had this experience.
