Objective: To detect the effect of intra-peritoneal instillation of local anesthetic with or without NSAIDs on pain relief after gynecological laparoscopy. Methods: Seventy five patients scheduled for laparoscopy were included in the study and randomly divided into three groups. At the end of the laparoscopic procedure, 100 mL normal saline in the first group, or 100 mL normal saline contains 200 mg lidocaine in the second group, or 100 mL normal slaine containing 200 mg lidocaine and 20 mg tenoxicam in the third group were splashed into the pelvis by the surgeon. Post-operative pain were monitored and compared. Results: The incidence and severity of immediate postoperative shoulder pain reduced from 44% of patients scoring 2-5 in saline group to 16% scoring 2-3 in lidocaine group and 8% scoring 2-3 in lidocaine-tenoxicam group. Compared with saline group, abdominal pain scores were significantly lower in lidocaine group and lidocaine-tenoxicam group over 24 hours after surgery. At 12 and 24 hours after surgery, abdominal pain scores were significantly reduced in lidocaine-tenoxicam group compared with lidocaine group. No pain on deep respiration was reported in 84%, and 68% in lidocaine-tenoxicam and lidocaine groups respectively compared to 12% in those in the saline group. The mean time to first request for analgesia was increased from (2.3 ±1.9) hours in saline group to (4.4 ± 2.4) hours in lidocaine group and to (8.3 ± 10.2) hours in lidocaine-tenoxicam group. Conclusion: Intraperitoneal balanced analgesia (local anesthetics ± NSAIDS) is a simple and safe technique for analgesia following gynaecological Laparoscopy.
