AbstractThis pilot case-control study was carried out to determine the value of intraperitoneal irrigation with a long-acting local anaesthetic agent in reducing postoperative analgesic requirements following gynaecological operative laparoscopy. Twenty women undergoing gynaecological laparoscopic surgery were recruited to receive dilute bupivacaine instilled into the peritoneal cavity at the completion of surgery. Analgesic requirements were assessed during the first 10 hours, and pain scores at 4 and 24 hours. Analgesic requirements were then compared with historical controls. Our results revealed that the total parenteral opioid requirement after bupivacaine was significantly less than in the control group (0.50 mg vs. 7.17 mg, P=0.006). Oral analgesic requirements were not significantly different between the two groups. Pain scores in the bupivacaine group showed no difference at 4 and 24 hours postoperatively. Intraperitoneal irrigation with dilute bupivacaine at the end of gynaecological laparoscopic surgery appears to reduce early postoperative analgesic requirements in this pilot study.
