Spinal Anesthesia Prior to Laparoscopic Hysterectomy Resulted in Decreased Postoperative Pain and Opioid Use

Study Objective: To determine if a pre -operative morphine/bupivacaine spinal injection prior to laparoscopic hysterectomy reduced postoperative pain and resulted in less opioid consumption during the hospital stay. Methods: A retrospective cohort study (Canadian Task Force Classification II -2) was conducted at a single institution regional referral center (community hospital) in North Carolina. Three hundred nineteen patients met criteria for inclusion: 192 received spinal anesthesia and 127 did not. Baseline demographics were similar between the two groups. Median pain scores were significantly lower in the treatment than the control group on day of surgery (DOS) (2 vs. 6; P < 0.001) and postoperative day 1 (POD1) (2 vs. 4; P < 0.001). Results: Primary outcomes were pain scores on DOS and POD1 and inpatient opioid use. Pain scores were obtained using the 0 to 10 Numerical Rating Scale. Opioids were converted to oral morphine milliequivalents (OME). Median opioid use was also significantly lower in the treatment than the control group on DOS (0 vs. 15.00 OME; P < 0.001) and POD1 (0 vs. 7.5 OME; P < 0.001). Median length of stay between the groups was not significantly different. Conclusion: Pre -operative morphine spinal injection for laparoscopic hysterectomy led to significantly lower pain scores and inpatient opioid consumption. Pre -operative spinal anesthesia for benign laparoscopic hysterectomy appears helpful for enhancing the postoperative experience.
