摘　　要：目的:观察右美托咪定、七氟醚复合麻醉对老年全膝关节置换术(TKA)患者脑损伤标志物、炎症应激反应的影响。方法:选取98例于2020年4月~2023年3月期间在我院接受治疗的老年TKA患者,采用随机数字表法将患者分为研究组(n=49,七氟醚联合右美托咪定麻醉)、对照组(n=49,七氟醚麻醉)。比较两组应激反应指标[皮质醇(Cor)、促肾上腺皮质激素(ACTH)]、脑损伤标志物[神经元特异性烯醇化酶(NSE)、S100β蛋白]、炎症因子[肿瘤坏死因子-α(TNF-α)、C反应蛋白(CRP)]水平,同时记录两组认知功能障碍(POCD)发生情况。结果:研究组术后1 d ACTH、Cor、TNF-α、CRP、S100β蛋白、NSE较对照组更低(P<0.05)。研究组的POCD发生率较对照组更低(P<0.05)。结论:老年TKA患者采用七氟醚联合右美托咪定麻醉,可减轻炎症应激反应和脑损伤,降低术后POCD发生风险。Objective:To observe the effects of dexmedetomidine and sevoflurane combined anesthesia on brain injury markers and inflammatory stress response in elderly patients undergoing total knee arthroplasty(TKA).Methods:98 elderly TKA patients who were treated in our hospital from April 2020 to March 2023 were selected.Patients were divided into study group(n=49,sevoflurane combined with dexmedetomidine anesthesia)and control group(n=49,sevoflurane anesthesia)by random number table method.The levels of stress response[cortisol(Cor),adrenocorticotropic hormone(ACTH)],brain injury markers[neuron-specific enolase(NSE),S100βprotein],inflammatory factors[tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)]were compared between two groups,and the incidence of postoperative cognitive dysfunction(POCD)were recorded.Results:The levels of ACTH,Cor,TNF-α,CRP,S100βprotein and NSE in study group were lower than those in control group 1 d after operation(P<0.05).The incidence of POCD in study group was lower than that in control group(P<0.05).Conclusion:Sevoflurane combined with dexmedetomidine anesthesia in elderly TKA patients can reduce inflammatory stress response and brain injury,maintain hemodynamic stability,and reduce the risk of postoperative POCD.
