To compare the efficacy of two doses of intraperitoneal bupivacaine for pain relief after operative laparoscopy in gynecology

Abstract

To evaluate the effect of two doses of intraperitoneal bupivacaine administration for pain relief after operative gynecological laparoscopy. Prospective randomized study. The study group comprised 52 women undergoing gynecological laparoscopic surgery. A dose of either 0.125% bupivacaine 10 ml (50 mg) or 0.25% bupivacaine (100 mg) was instilled intraperitoneally at the end of the procedure. Pain scores were recorded in the postoperative period on a scale of 0-10 at 2, 4, 6 and 8 h intervals after the surgery. Any other side effect and the time and dose of analgesia required were noted. The results were compared in the two groups. One hundred milligrams of bupivacine provided pain relief for a longer duration (8 h), as compared to 50 mg of the drug (4-6 h). This difference was statistically significant. Analgesic requirement was also less in the 100 mg group. One hundred milligrams of intraperitoneal bupivacaine is much better than 50 mg in relieving pain after laparoscopic surgery.
