Retrospective Analysis: Comparative Effects of General Anesthesia versus Quadratus Lumborum Block-Supplemented General Anesthesia on Postoperative Outcomes in Patients Undergoing Laparoscopic Myomectomy

Background and Objective: This retrospective study analyzed to compare the effects of general anesthesia (GA) versus combined anesthesia (CA) on postoperative pain and negative emotions in patients undergoing uterine fibroid surgery, providing evidence for optimizing anesthesia protocols aiming to achieve more effective analgesia and improve patient satisfaction scores. Methods: A retrospective analysis was conducted on data from 148 patients who underwent uterine fibroid surgery at a tertiary hospital between April 2023 and December 2024. Patients were divided into a control group (GA) and a study group (CA) based on anesthesia type. The control group received conventional GA, while the study group received ropivacaine quadratus lumborum block (QLB) combined with GA. After propensity score matching (PSM), 74 patients were included in each group. The primary outcome was postoperative 2-12h visual analog scale (VAS) pain scores. Secondary outcomes included stress indicators (ACTH, Cor), emotional scales (SAS/SDS), cognitive function (MMSE), and sleep quality (PSQI). Results: The study group had shorter anesthesia duration, postoperative flatus time, postoperative ambulation time, and hospital stay compared to the control group (all P
