Laparoscopic myomectomy is a commonly performed minimally invasive gynecologic procedure. However, surgical trauma, tracheal intubation, and pneumoperitoneum may induce pronounced perioperative stress responses, resulting in hemodynamic instability, postoperative pain, inflammatory activation, sleep disturbance, and anxiety, which can delay postoperative recovery. Stellate ganglion block (SGB) is a sympathetic nerve modulation technique that has been shown to attenuate stress-related sympathetic overactivity. This study aimed to evaluate the clinical effects and safety of ultrasound-guided right-sided stellate ganglion block combined with standardized general anesthesia in patients undergoing laparoscopic myomectomy. In this randomized controlled study, a total of 240 patients scheduled for laparoscopic myomectomy were randomly assigned to either a combined block group (ultrasound-guided right-sided SGB before anesthesia induction plus general anesthesia) or a general anesthesia group (sham saline injection plus general anesthesia). Perioperative hemodynamic parameters, heart rate variability, postoperative pain scores, analgesic requirements, recovery profiles, inflammatory stress markers, sleep quality, anxiety levels, and adverse events were compared between groups. This study was retrospectively registered after completion. The results are intended to provide evidence for optimizing perioperative management and enhancing recovery in patients undergoing laparoscopic myomectomy.
