Intraoperative administration of systemic/epidural/intrathecal morphine on the quality of recovery following substitutional urethroplasty with buccal mucosal graft: A randomized control trial.

Background and Aims: Substitutional urethroplasty with buccal mucosal grafting for urethral stricture is associated with significant pain, and thus inappropriate perioperative pain management could delay postoperative recovery. The objective of our research was to determine the effects of analgesia with systemic or epidural or intrathecal morphine on quality of recovery (QoR) in patients undergoing substitutional urethroplasty with buccal mucosal grafting. Material and Methods: This prospective, double-blinded, randomized control trial was conducted over 2 years in ASA I and II patients who underwent substitutional urethroplasty with buccal mucosal graft. Patients were randomized into three groups, and Group A received systemic morphine (0.1 mg/kg), Group B received epidural morphine (3 mg), and Group C received intrathecal morphine (150 μg). The QoR between the groups were compared postoperatively using the 40-item QoR questionnaire, and the hemodynamic variations, time taken for ambulation, resumption of oral intake, and incidence of complications were also compared. Results: Out of the recruited 93 patients, 88 patients were analyzed. The QoR score for each domain was comparable between the three groups. The total QoR score for systemic, epidural, and intrathecal morphine groups were 189 (185–191), 189 (187–191), and 185 (183–189), respectively. Additionally, the hemodynamic variations, time taken for ambulation, and resumption of oral intake were comparable between all three groups except the incidence of postoperative nausea and vomiting (PONV) and pruritis, which were higher in the intrathecal group. Conclusion: All three modalities, namely systemic morphine (0.1 mg/kg), epidural morphine (3 mg), and intrathecal morphine (150 μg), offer similar QoR after substitutional urethroplasty. However, the incidence of PONV and pruritis was higher with the administration of intrathecal morphine. [ABSTRACT FROM AUTHOR]
