Abstract
Background: To determine the effect of a paracervical block in laparoscopic hysterectomy on postoperative pain relief. Method: A total of 86 patients scheduled for total laparoscopic hysterectomy for benign gynecologic diseases were randomly assigned to the experimental group (n = 43) and the control group (n = 43). Patients were received a paracervical injection that was either 10 mL of 0.5% bupivacaine with 1 : 200,000 epinephrine or 10 mL of normal saline. The primary outcome was the postoperative pain score which was assessed using a visual analog scale at 2, 4, 6, 8, and 12 hours after surgery. The secondary outcome was the postoperative rescue analgesic requirement within 12 hours after surgery. Results: Baseline characteristics were similar in both groups. Postoperative pain scores did not significantly differ between groups. Rescue analgesia requirements were also statistically similar in both groups. Conclusion: Adding a paracervical block with preemptive local analgesia in patients undergoing laparoscopic hysterectomy did not reduce postoperative pain and postoperative rescue analgesia requirements.
