obviously don't let that happen in the first place, my service carries fentanyl and it is pretty awesome about not having much of the side effects of other narcs, and while i don't think that too many medics rush to give narcan, i think they are too... text book about giving a certain dose. if a pt is in resp. distress/failure due to a narcotic overdose, narcan should be titrated to restore the pt's breathing ability, not completely reverse the effect of any opiates in the pt's system. and we can look at that on both ends of the spectrum (and i may be running into different scenarios than you since i'm doing mostly field work and you are in a critical care unit). A. coming across a pt who is not breathing due to recreational drug use. ABC's, 02, IV, monitor, and narcan titrated to effect, i.e., the pt starts breathing on their own. Now, if we were to give a "standard" dose and completely block all effects of the opiate, pt wakes up and becomes highly agitated at us for ruining their several hundred dollar high that they just had thus creating an unsafe scene. On the other end of the spectrum, pt is on fentanyl or other opiate of pain control due to... terminal cancer or whatever. pt is overdosed on opiate, and stops breathing, give narcan titrated again to effect of pt able to breath on their own (with good perfusion and all that) but not to block out the needed pain relief of narcotic therapy. Again, working streets and the area i'm in i run into scenario A. more often so the patient is the idiot for making him/herself stop breathing into the first place.
