I just have to agree with the others in saying that I really hope you aren't serious....
Intubation is a risky procedure that is justified only when those risks are outweighed by the benefits.
If there is no other way to secure the airway or maintain an adequate minute volume, then the benefits of intubation probably outweigh the risks. However, if you have a medication at hand that can safely reverse the respiratory depression, then opting instead to use a risky procedure is pure assault, IMO.
Many people talk about how "dangerous" nalaxone is, but frankly I think those people are dead wrong, and probably used to using toxic doses of it. I guarantee prehospital intubation causes far more problems than does prehospital administration of reasonable doses of nalaxone.
Exactly. This is one of those (relatively few, IMO) times where noninvasive capnography would be really useful.
Dilute a 0.4 mg / 1ml vial in 9 ml for a 40mcg/ml concentration, and push 1-2 cc's at a time, watching the capnograph (or chest rise, if you don't have capnography).
Draw a up your entire 2 mg / 1 ml vial into a 10ml syringe and squirt half of it out. Then draw up 9.5 ml of NS so that you have 1 mg in 10 ml, or 100 mcg/ml. Push half a cc at a time = 50 mcg per dose.
