腹腔镜辅助腹横肌平面阻滞与切口局麻对腹腔镜阑尾切除术后镇痛效果的比较OA

Objective:To compare the efficacy and safety of laparoscopic-assisted transversus abdominis plane(Lap-Tap)block versus wound infiltration(WI)for postoperative analgesia in laparoscopic appendectomy(LA).Methods:A total of 74 patients with acute appendicitis who underwent LA from Aug.2021 to May 2025 were enrolled and randomly divided into the Lap-Tap group(n=38)and the WI group(n=36)by means of the random number table method.Patients in the Lap-Tap group received Lap-Tap block with ropivacaine and saline injection at abdominal incisions,while those in the WI group received ropivacaine infiltration at surgi-cal incisions and saline injection for Lap-Tap block.Pain scores at 2 h,6 h,12 h,24 h and 48 h after operation,as well as rescue analge-sia,time to first ambulation,time to first flatus,and related complications were recorded.Results:There were no statistically significant differences in pain scores at 2 h,6 h,12 h,24 h and 48 h after operation,the dosage of flurbiprofen axetil within 48 h postoperatively,and the number of patients receiving opioid analgesia between the two groups.No procedure-related complications occurred in either group.Conclusions:No significant difference is found in pain scores within 48 h after operation between Lap-Tap block and WI during LA.WI may be more suitable for local postoperative analgesia in LA due to its lower technical difficulty.
