Neuromuscular-blocking agents are used to produce adequate muscle relaxation during anesthesia to reduce the use (and adverse effects) of general anesthesia, ease endotracheal intubation and prevent laryngospasm, and decrease muscular activity in electroshock therapy. Neuromuscular-blocking agents have no effect on the pain threshold, memory, or consciousness.
