Lidocaine for LESS Postoperative Shoulder Pain Alleviation

Objective: To evaluate the efficacy of subdiaphragmatic spray of 0.08% lidocaine in relieving postoperative acute pain and psychological status of patients undergoing single-port laparoscopic surgery for benign gynecological diseases, and to provide evidence-based basis for optimizing postoperative analgesic strategies. Methods: A single-center, prospective randomized controlled study was conducted. A total of 100 patients scheduled for elective single-port laparoscopic surgery due to uterine fibroids, ovarian cysts, or other benign gynecological conditions were selected from the General Gynecology Center of Peking Union Medical College Hospital. They were divided into the experimental group (n=50) and the control group (n=50) using a random number table. The experimental group received 50 ml of 0.08% lidocaine solution sprayed on the bilateral subdiaphragmatic regions at the start of surgery, while the control group underwent standard ERAS without any pharmaceutical intervention in the subdiaphragmatic area. The primary endpoint was the Numerical Rating Scale (NRS) score for resting pain at 6 hours postoperatively. The secondary endpoints included NRS scores at 1, 2, 12, and 24 hours postoperatively, total consumption of analgesics within 48 hours after surgery, incidence of adverse reactions, patient satisfaction, and scores of psychological and sleep scales (Distress Thermometer, GAD-7, etc.) at 30 days postoperatively.
