Preoperative versus Postoperative Rectus Sheath Block for Acute Postoperative Pain Relief - A Retrospective cohort study

Not Applicable

• Conditions: Patients undergoing laparoscopic surgery in surgery, urology, and gynecology

• Registration Number: JPRN-UMIN000047494
• Lead Sponsor: The Jikei University Katsushika Medical Center

Brief Summary

In total, 609/14,284 patients were included (pre-RSB group, 227 patients; post-RSB group, 382 patients). After PS matching, 97 patients were assigned to both groups. Although the time from extubation to the first analgesic request was not significantly different between the 2 groups (322 vs 294 minutes, P = .57), the patients in the pre-RSB group showed a lower risk of postoperative first analgesic administration after PS matching (adjusted hazard ratio, 0.71; 95% confidence interval, 0.53-0.95; P = .023).
