Well, it's nearly impossible. Generally you make the target angry, badly damaged or dead.
See also "knock out" darts, chloroform on cloth etc. Anaesthetic hypo is really really slow and needs body weight known (too little and target is simply slow, too much and they die). Respiratory anaesthetic is very dangerous, hence everything in a hospital theatre is monitored and an expert manages it. A kidnapper is as likely to kill or cause brain damage with chloroform etc, and it's slow. So in real life they threaten with a weapon and bundle the victim into a vehicle, even then it often goes wrong.
There is a reason why "shoot to kill" is used rather than a hypo-dart with dangerous animals or armed criminals or terrorists.
