Intrathecal morphine dose optimization in robotic-assisted laparoscopic hysterectomy: a dual-center cohort study

Abstract Background Optimized perioperative analgesia is a critical component of Enhanced Recovery After Surgery (ERAS) pathways in robotic-assisted laparoscopic hysterectomy (RALH). In high-volume robotic programs, predictable pain control may influence early mobilization, postoperative stability, and discharge planning. This study evaluated the analgesic efficacy and safety of two low-dose intrathecal morphine (ITM) regimens (0.10 mg vs. 0.15 mg) in patients undergoing RALH. Methods We conduct
