While an intravenous injection of some anesthetics can knock out a person in under 30 seconds, an ''intramuscular'' injection -- whichinjection—which is the only kind you're going to get on a person who's resisting vigorously -- canvigorously—can take upwards of 15 minutes or more. Think of all the safari shows where they trail after the tranked wildlife waiting for the drug to finally take effect.
 
However, this is never fast enough for television -- whichtelevision—which has, after all, only 40 minutes (after commercials and credits) to present a [[Dramatic Hour Long|one hour drama]]. Thus, every anesthetic gets upgraded to "instant effect". Exceptions: when the spreading muscular paralysis can be played for laughs or the writers want to show that a character or animal is extremely tough. In the latter case, multiple darts/injections may be used to speed up the process, apparently without risk of fatal overdose.
 
Likewise, goons using rags soaked with chloroform or ether to subdue and then kidnap some soon-to-be [[Damsel in Distress]] is a staple of pulp detective novels, and similar scenes have occurred not infrequently in movies and on television. But in real life, rendering someone unconscious that way not only tends to take several minutes, but also from time to time kills the intended victim ([[Don't Try This At Home]]. Seriously).
Line 20:
Nor is it possible even for a practiced and steady hand to forcibly stab someone with a needle in, say, the neck, and hit an artery or vein. They are quite small relative to the size of the neck, and every person's anatomy is different. A doctor creeping up behind a person with a syringe would hit a blood vessel only by blind luck. The same is true of a tranquilizer dart. Both are used in real life (though the shoulder or the buttocks are used when injecting a person against their will, not, for obvious reasons, the neck.) But they take several minutes, at a minimum, to take effect.
 
Also note that in general, a medication which produces perfect unconsciousness also produces apnea -- whichapnea—which is to say, the victim stops breathing. Calming a person with a sedative is one thing -- butthing—but the total oblivion seen in TV and movies is typically only induced by the medical profession when they intend to support the patient's breathing via a bag-valve mask or a ventilator.
 
There are also areas of the body where it is ''incredibly stupid'' to stab someone with a hollow needle, while often in fiction this is disregarded. Also the drug make-up for intramuscular serum and intravenous serum can be different depending on the drug, with both IM and IV injections needing to be injected ''carefully'' to avoid bruising and missing the target.
