AbstractWe investigated whether laparoscopic vs open surgical approaches affected the duration of neuromuscular blockade following a single bolus dose of rocuronium. Fifty-three female patients underwent either laparoscopic or open gynaecological surgery. Rocuronium 0.6 mg.kg(-1) was administered to achieve neuromuscular blockade in all subjects, and adductor pollicis train-of-four responses following ulnar nerve stimulation were monitored with mechanomyography. The mean (SD) time from injection of rocuronium until spontaneous recovery of the first twitch, and to 5% and 25% of baseline, was significantly prolonged in the laparoscopic group (27.2 (8.3) min, 31.3 (9.1) min and 38.1 (10.6) min, respectively) compared with the open surgery group (21.1 (5.8) min, 25.6 (6.3) min and 31.2 (6.7) min, respectively). Changes in liver function both before surgery and at 24 h postoperatively were similar between the two groups (p > 0.05). Our findings suggest that neuromuscular blockade may be prolonged following a single bolus dose of rocuronium given during laparoscopic procedures.© 2014 The Association of Anaesthetists of Great Britain and Ireland.
