title: A clinical comparison of atracurium and vecuronium in women undergoing laparoscopy.
abstract: In a double-blind, prospective, randomised trial in 30 women undergoing laparoscopy, atracurium and vecuronium were compared in equipotent (2 X ED95) doses. In the atracurium group, first twitch depression was significantly greater at one minute, and degree of fade significantly greater at one and two minutes, but thereafter neuromuscular monitoring showed no significant difference between the groups. Clinically there was no significant difference between the drugs. Mild intraoperative hypotension was equally common in both groups as was sinus bradycardia. Reversal and recovery were comparable in the two groups. Neostigmine was required in all patients and in three (one atracurium, two vecuronium) a second dose was required in all patients and in three (one atracurium, two vecuronium) a second dose was administered on clinical grounds. Antagonism of the neuromuscular block is required with surgery of this duration despite the intermediate duration of action of the relaxant drugs.
