Abstract

Background: An adequate anesthesia technique generates appropriate postoperative analgesic properties and decreases the patient’s stress response. This will lead to decreased morbidity and mortality associated with immunology disturbances, such as infection, prolonged wound healing, and sepsis. Objectives: The aim of this study was to compare interleukin-6 (IL-6) and C-reactive protein (CRP) concentrations, as the markers of the stress response, between continuous epidural and quadratus lumborum (QL) block as postoperative analgesia techniques among living kidney donors. Methods: Sixty-two patients were randomly divided into two equal groups: continuous epidural and QL block. A group received bilateral QL block with 20mLof bupivacaine 0.25% and the other received 6 mL/hour of bupivacaine 0.25% continuously via an epidural catheter. Prior to extubation, the QL block group received bilateral QL block with the same dose and the continuous epidural group was administered with 6 mL/hour of bupivacaine 0.125%. Blood samples were drawn to compare IL-6 and CRP concentrations after intubation (preoperatively), directly after surgery, 24 hours postoperatively, and 48 hours postoperatively. Postoperative pain was measured with the numerical rating scale (NRS). Morphine requirement and duration of catheter usage were also measured postoperatively. Side effects within 24 hours postoperatively were noted. Data were analyzed with independent t-test or Mann- Whitney test. Results: No difference was observed between the groups in the plasma concentration of IL-6 either after surgery or 24 hours postoperatively (P = 0.785 and P = 0.361, respectively) although the mean IL-6 concentration 24 hours postoperatively was lower in the QL block group than in the continuous epidural group. CRP concentration was not significantly different between the groups either after surgery or 48 hours postoperatively (P = 0.805 and P = 0.636, respectively). Conclusions: There was no significant difference in IL-6 and CRP concentrations between continuous epidural and QL block among living kidney donors. Both continuous epidural and QL block techniques showed comparable postoperative analgesic properties among living kidney donors undergoing laparoscopic nephrectomy.
