Difference of Recovery of Neuromuscular Function in Adductor Pollicis and Flexor Hallucis Brevis Following Muscle Relaxation with Vecuronium
In general anesthesia, neuromuscular function should be monitored to detect the degree of recovery from muscle relaxation for safety use of neuromuscular blocking agent. The method of the detection involves measuring the force of the muscle contraction induced by electrical stimulation of the peripheral nerve innervating of a muscle. Ulner nerve and Adductor Pollicis muscle are usually evaluated for this purposed. However these cannot be used, for example, in the case of burn or trauma in the hands, forearm surgery, or head and neck surgery. In these cases, Tibial nerve and Flexor Hallucis Brevis muscle may be substituted.
