Abstract
Background: The research aimed to assess the effectiveness of inside-out anterior quadratus lumborum (QL3) block and local wound infiltration in managing postoperative pain and total morphine dosage following kidney transplantation. Methods: In this prospective, randomized, double-blind study; 46 end-stage renal disease patients undergoing kidney transplantation were randomly allocated into 2 groups: a QL group (n = 23) receiving 20 mL of 0.25% bupivacaine using the ultrasound-assisted inside-out technique before wound closure, while the local wound infiltration (LA) group (n = 23) receiving the same dose around the surgical wound and drain at the time of skin closure. The primary outcome measure was the numerical pain rating scale, with secondary outcomes including amount of morphine consumption at various postoperative time points (2nd, 4th, 6th, 12th, 18th and 24th hours). Results: Patients in the QL group had significantly lower numerical rating scale scores at the 2nd and 4th hours, both at rest and during movement (P < .05). Although pain scores at rest and during movement at later time points were lower in the QL group compared to the LA group, these differences were not statistically significant. Cumulative morphine consumption at postoperative 4th, 6th, 12th, 18th and 24th hours was significantly lower in the QL group (P < .05). No patients experienced complications from the QL3 block. Conclusion: Ultrasound-assisted inside-out QL3 block significantly reduced postoperative pain levels at the 2nd and 4th hours, both at rest and during movement, and led to a reduction in cumulative morphine consumption from the 4th hour postoperatively, and persisting throughout the 24-hour period.
