A prospective, randomized study comprised 125 outpatient laparoscopic sterilization patients who had received either general anaesthesia or local anaesthesia together with intravenous sedation. The patients who had received local anaesthesia suffered significantly less postoperative pain and sore throat. Recovery and discharge were similar in the two groups, but those given a general anaesthetic were more drowsy in the evening on the day of operation. The time spent in the operating theatre was significantly shorter for the group given local anaesthesia, and the costs were lower. The majority of patients from both groups would prefer local anaesthesia and sedation for a similar procedure in the future. We conclude that local anaesthesia by intravenous sedation is the method of choice for laparoscopic sterilization.
