Abstract:
Objective To investigate the impact of the COX-2 specific inhibitor parecoxib on postoperative serum cytokines and early cognitive function in the elderly patients undergoing knee replacement.Methods Seventy-two elderly patients undergoing knee replacement were divided into a control group (group Ⅰ)and parecoxib group (group Ⅱ).MMSE score were compared at preoperative 1 d and postoperative 1 d,3 d,7 d.Before induction of anesthesia (T1 ),postoperative 6 h (T2 ),1 d (T3 ),3 d (T4 ),7 d (T5 ),the serum IL-1β,IL-6 concentrations were measured,meanwhile the serum S-100βwere measured in T2 .Results At postop-erative 1 d,3 d,the MMSE score in group Ⅰ was significantly lower compared with the preoperative (P <0.05).IL-6 in T2 ,IL-1βin T3 increased in both group.In group Ⅱ,three days later,the exaltation of plasma inflammatory factors returned to the preopera-tive level,but this process last untill T5 in group Ⅰ.The plasma concentration of IL-6 in T2 ,T3 ,T4 and IL-1βin T3 ,T4 in group Ⅰwere higher than group II (P <0.05).At T2 ,the serum S-100βin group Ⅰ was (1 625 ± 364)pg/mL higher than group Ⅱ(1 263 ±174)pg/mL(P <0.05).Conclusion The protective effection of COX-2-specific inhibitor parecoxib upon postoperative cognitive decline in elderly patients undergoing orthopedic surgery may be related to inhibition of peripheral cytokine release.
