Mivacurium chloride administration by infusion.

As a consequence of its rapid hydrolysis by plasma cholinesterase, mivacurium has a short duration of action, and recovery from neuromuscular blockade is rapid (5-95% twitch recovery = 13-15 min). Mivacurium is easy to titrate to individual patient requirements; the average infusion rate to maintain neuromuscular blockade at 89-99% twitch suppression during N2O/opioid anaesthesia is 6-7 micrograms/kg per min in adults and approximately 14 micrograms/kg per min in children. There is no evidence of a cumulative effect of mivacurium; recovery is unaffected by dose administered or duration of infusion. These characteristics make mivacurium a very suitable agent for use by infusion.
