Patient-controlled versus scheduled, nurse-administered analgesia following vaginal reconstructive surgery: a randomized trial.

Objective: To determine whether patient-controlled analgesia or scheduled intravenous analgesia provides superior pain relief and satisfaction with pain control after vaginal reconstructive surgery.

Study Design: Fifty-nine women scheduled for vaginal reconstructive surgery were enrolled in this randomized trial. Operative procedures and postoperative orders were standardized. Visual analog scales for pain and satisfaction with pain control were recorded during the hospital stay and 2 weeks after surgery.

Results: Patients receiving patient-controlled analgesia had less pain on postoperative day 1, 25 mm vs 39 mm, on visual analog scales (P = .007). Although this group used twice as much hydromorphone (3.57 mg vs 1.48 mg, P < .001), there was no difference in side effects, length of hospital stay, or complications. For the sample overall, larger amounts of narcotic used correlated with higher pain scores (r = 0.364, P = .009) and worse satisfaction scores (r = -0.348, P = .012).

Conclusion: In patients undergoing vaginal surgery, patient-controlled analgesia offers superior pain relief on postoperative day 1 when compared with scheduled, nurse-administered hydromorphone.
