Effect of topical lignocaine on postoperative pain after laparoscopic tubal sterilisation in awake patients

Objective. To evaluate postoperative pain after administration of topical lignocaine during laparoscopic sterilisation in awake patients using Falope rings. Study design. Thirty-six women who underwent laparoscopic tubal sterilisation were assigned randomly to receive topical lignocaine (1%, 10 ml) or placebo. A 4-point verbal rating score was used to assess pain at ring application, 15 minutes and 1 hour thereafter, and at discharge. Side-effects, complications, extra pain medication requirements and satisfaction rates at follow-up were assessed postoperatively. Results. The pain scores were significantly lower in the lignocaine group than in the placebo group at 15 minutes (2.06 v. 2.94) and 1 hour (1.187 v. 2.33) and at discharge (0.18 v. 1.1). The side-effects and complications were similar in the two groups. Procedure satisfaction and acceptability were higher in the lignocaine group (p=0.005). Conclusion. Topical lignocaine applied to the fallopian tubes at the time of laparoscopic tubal sterilisation decreases postoperative pain and improves satisfaction rates even if done under sedation and local anaesthesia.
