Description
Summary:Preemptive analgesia is initiating an analgesic regimen before the onset of the noxious stimulus. Damages to the tissue caused by surgical trauma generate noxious response conveyed to the central nervous system (CNS) by two pathways, neural pathway and circulatory pathway. This study is a double- blinded clinical trial that included 48 patients undergoing lower extremity orthopedic surgery. The subjects were divided into two groups: group I (n=24) received 10 mL bupivacaine 0.25% from epidural route, and group II (n=24) received 10 mL NaCl 0.9% from epidural route as the control group before induction of anesthesia. Both groups were anesthetized under general anesthesia. Group I received 5 mL bupivacaine 0,5% every 90 minutes and group II received 5 mL NaCl 0,9 with similar time intraoperatively. Post-operatively, both groups received continuous bupivacaine 0,25% 4 mL/ hour until 24 hours after surgery. Measurements of cytokine levels: tumor necrosis factor-α (TNF-α), interleukin- 1β (IL-1β), IL-6 and IL-10 were done before induction of anesthesia, in the early post-operative period, at 4, 8, and 24 hours after surgery. Group I showed lower level proinflammatory cytokines level compared with group II but the difference was not statistically significant (p>0.05). The level of anti-inflammatory cytokine was higher in group I, but the difference was not statistically significant (p>0.05). Pain intensity at 4 hours, 8 hours, 24 jam hours post operative was lower significantly (p<0.05) Hemodynamic responses was lower in group I but not significant (p>0.05) excepst at early postoperative period (p<0.05). Generally, preemptive epidural analgesia was able to suppress the cytokine responses, but not completely. In conclusion, preemptive epidural analgesia is associated with better analgesia and better hemodynamic stability compared without preemptive epidural, but unable to suppress the production of proinflammatory and anti-inflammatory cytokines.
