摘　　要：目的:研究Narcotrend指数(NI)指导下双通道靶控输注麻醉对老年患者术后早期认知功能的影响,并与单通道对比。方法:选择择期全麻仰卧位非心脏手术患者100例,年龄65～80岁,体质指数(BMI) 18～25 kg·m-2,ASA分级为Ⅰ～Ⅲ级,术后住院时间≥7 d。采用随机数字表法将患者随机分为两组:双通道组(S组)和单通道组(D组),每组50例。S组丙泊酚和瑞芬太尼均采用靶控输注(TCI),在NI指导下采用固定比例调节丙泊酚和瑞芬太尼靶浓度,维持目标麻醉深度; D组丙泊酚采用靶控输注,瑞芬太尼采用恒速输注模式。由麻醉医师按照身高和体重等指标,经验性地调节丙泊酚靶浓度和瑞芬太尼泵注速度,维持目标麻醉深度。分别于术前1 d、术后3 d和术后7 d进行简易智能量表评分(MMSE)和视觉模拟评分(VAS),分别评估患者认知功能和疼痛程度。结果:各组与术前相比,术后3 d和7 d MMSE评分显著下降(P <0. 05);而与术后3 d相比,各组术后7 d MMSE评分显著升高(P <0. 05);组间比较,S组术后3 d和7 d MMSE评分显著高于D组(P <0. 05)。术后3 d和7 d,两组VAS评分差异均无统计学意义(P> 0. 05)。结论:NI指导下双通道靶控输注麻醉与单通道麻醉相比,对老年患者术后早期认知功能有一定保护作用。Objective:To investigate whether the dual-channel target anesthesia under Narcotrend index(NI)guidance having an advantage in protecting early postoperative cognitive function of the olderly patients compared with the single-channel.Methods:100 patients under general anesthesia for elective noncardiac surgery with supine position,aged 65 to 80 years old,BMI 18-25 kg·m-2,ASAⅠ-Ⅲ,postoperative hospital stay≥7 days,were enrolled.These patients were randomly divided into two groups:S group and D group,50 cases in each group.In S group the anesthesiologist chose propofol and remifentanil treated with target-controlled infusion(TCI),under the guidance of NI using a special algorithm to adjust the propofol and remifentanil target concentration in plasma,to maintain the target anesthesia depth;however the anesthesiologist adjust the propofol target concentration and remifentanil injection rate which were chosed constant rate infusion according with the experience to keep the anesthesia depth in D group.MMSE score and VAS score were performed at 1 day before operation,3 days and 7 days after operation.Results:MMSE score decreased at 3 days and 7 days after operation both in S group and D group(P<0.05).And the MMSE score increased at 7 days after operation compared with that of the 3 days post-operatively(P<0.05).Compared with the D group,MMSE score of the S group was higher at 3 and 7 days after operation(P<0.05).However,no difference was found between two groups on VAS scores at both 3 and 7 days post-operatively(P>0.05).Conclusion:NI-guided dual-channel target-controlled infusion anesthesia protects post-operative cognitive function on the geriatric patients compared with single-channel anesthesia.
