Abstract
OBJECTIVE: This study aimed to compare the efficacy of local anaesthetic infiltration to trocar wounds and intraperitoneally on postoperative pain as a part of a multimodal analgesia method after laparoscopic cholecystectomies. METHODS: The study was performed on 90 ASA I-III patients aged between 20 and 70 years who underwentelective laparoscopic cholecystectomy. All patients had the same general anaesthesia drug regimen. Patients were randomized into three groups by a closed envelope method: group I (n=30), trocar site local anaesthetic infiltration (20 mL of 0.5% bupivacaine); group II (n=30), intraperitoneal local anaesthetic instillation (20 mL of 0.5%) and group III (n=30), saline infiltration both trocar sites and intraperitoneally. Postoperative i.v. patient controlled analgesia was initiated for 24 h. In total, 4 mg of i.v. ondansetron was administered to all patients. Visual analogue scale (VAS), nausea and vomiting and shoulder pain were evaluated at 1., 2., 4., 8., 12., 24. hours. An i.v. nonsteroidal anti-inflammatory drug (NSAID) (50 mg of dexketoprofen) as a rescue analgesic was given if the VAS was ≥5. RESULTS: There were no statistical significant differences between the clinical and demographic properties among the three groups (p≥0.005). During all periods, VAS in group I was significantly lower than that in groups II and III (p<0.001). Among the groups, although there was no significant difference in nausea and vomiting (p=0.058), there was a significant difference in shoulder pain. Group III (p<0.05) had more frequent shoulder pain than groups I and II. The total morphine consumption was higher in groups II and III (p<0.001 vs p<0.001) than in group I. The requirement for a rescue analgesic was significantly higher in group III (p<0.05). CONCLUSION: Trocar site local anaesthetic infiltration is more effective for postoperative analgesia, easier to apply and safer than other analgesia methods. Morphine consumption is lesser and side effects are fewer; therefore, this method can be used as a part of common practice.
