Savage Land, Strange Heart (2) - S3-E9
Continuity mistake: When Wolverine is calling out to Rogue and Storm, his claws are retracted into his arms. When the shot changes, his claws are extended. His hands also go from being cupped around his mouth to being instantly down at his sides. (00:19:15)
Answer: The drugs that anaesthesiologists use for people undergoing surgery (such as IV drugs and inhaled gases) relax muscles to the point that the patient can't move and becomes unconscious. But with monitored sedation (as opposed to general anaesthesia), there can be varying° of drowsiness perhaps with the ability to talk. If you've heard of "anesthesia awareness", this may be a condition close to what you are asking about. Not enough general anesthesia is administered (the amount needed was misjudged or deliberately lowered because of a dangerous situation but hoped to be enough) and the patient becomes aware during surgery but cannot move. General anesthesia typically uses nitrous oxide and variations of ether. Barbiturates/ sedatives/ tranquilizers - even enough alcohol - in varying amounts over time can keep a person largely immobile. (I'm not mentioning any specific drugs).
