Vecuronium bromide in anaesthesia for laparoscopic sterilization.
Vecuronium bromide 70 micrograms kg-1 was used to facilitate tracheal intubation and provide neuromuscular blockade in 52 patients undergoing laparoscopic sterilization. Anaesthesia was maintained with 67% nitrous oxide in oxygen. Patients were monitored clinically and by tactile assessment of the evoked response of the adductor pollicis to a supramaximal train-of-four stimulation. Intubating conditions were assessed at 90 s in the first 33 patients, and were poor. They improved significantly in the subsequent 19 patients when intubation was delayed until 150 s (P less than 0.05). Operating conditions were good in all except two patients. Residual neuromuscular blockade was antagonized rapidly at completion of surgery by neostigmine 2.5 mg i.v., which was administered provided there was at least one twitch response. The mean duration of the procedure was 14.3 min (SD 2.5 min). The mean time from injection of neostigmine to satisfactory spontaneous breathing and neuromuscular recovery was 1.6 min (SD 0.7 min).
