老年患者静吸复合麻醉深度术后认知功能的观察(1)
摘要:目的 探讨静吸复合麻醉深度与老年患者术后认知功能的相关性。方法 选择进行择期手术需行静吸复合麻醉的65岁以上老年150例,将患者分为A组、B组和C组。比较三组在术前1 d,术后1 d、2 d的认知功能评分。结果 术前1 d,三组MMSE评分和TMT评分差异无统计学意义,术后1 d、2 d三组MMSE评分、数字广度测验和TMT评分在时间、组间、交互上比较差异有统计学意义,B组术后1 d、2 d MMSE评分均高于A组和C组,TMT评分均低于A组和C组。结论 静吸复合麻醉深度与老年患者认知功能存在相关性,当测定BIS值在40~50范围内,对机体认知功能的影响较小,可用于指导临床治疗。

Abstract:Objective To investigate the correlation between the depth of anesthesia and postoperative cognitive function in elderly patients.Methods Elective surgery for anesthesia of 65 years of age or older in 150 cases,the patients were divided into A group,B group and C group.The three groups were compared before operation,1 d,1 d after operation.2 d cognitive function score.Results Before operation,1 d,three groups had no statistically significant differences in MMSE score and TMT score, postoperative 1 d,2 d,three groups of MMSE score,TMT score and digit span test in time between groups,the difference was statistically significant interaction on the B group,1 d after operation.2 d MMSE were higher than that of A group and C group,TMT scores were lower than A group and C group.Conclusion Intravenous Inhalation Anesthesia in elderly patients with cognitive depth correlation function,the determination of BIS value in the range of 40~50,the smaller effect on the cognitive function,which can be used to guide the clinical treatment.

術后认知功能障碍(Postoperative Cognitive Dysfunction,POCD)是老年患者术中麻醉后常出现的一种并发症,严重影响患者术后效果及出院后的生活质量。据统计,POCD患者发展为痴呆的风险较高,是认知功能正常老年人10倍以上[1],与老年患者术中麻醉情况紧密相关。为探讨静吸复合麻醉深度与老年患者术后认知功能的相关性,本研究选取我院收治的150例老年患者进行研究,现报道如下。
1 资料与方法
1.1一般资料 本研究入选150例患者,均为2015年7月~2016年6月在我院行择期需行静吸复合麻醉老年患者。其中男70例,女80例,年龄65岁以上,ASA分级在Ⅰ~Ⅲ级,体重指数(BMI)19~24 kg/m2,8年以上受教育程度,术前简易精神状态量表评分>24分。手术种类神经外科除外,采用脑电双频指数(Bispectral Index,BIS)测定麻醉深度,根据测定BIS值,将患者分为A组(BIS值50~60,50例),B组(BIS值40~50,50)例和C组(BIS值30~40,50例)。三组入选患者的性别、年龄、手术种类等比较差异无统计学意义(P>0.05),存在可比性。

1.2麻醉方法 所有入选患者均行静吸复合麻醉,具体操作如下:①麻醉前:采用多功能监护仪常规监测患者心电图、血压、心率、脉搏氧饱和度及呼吸末二氧化碳分压,并连接脑电双频指数仪;②麻醉诱导:将芬太尼4 μg/kg、咪达唑仑0.05 mg/kg、罗库溴铵0.6 mg/kg、丙泊酚1 mg/kg等药物,经气管内插管行静脉快速诱导,容量控制模式,IPPV控制通气;③麻醉维持:术中吸入呼气末浓度为1.0%~1.5%七氟醚和持续微量泵注0.3~1.0 μg/kg·min瑞芬太尼,并间断静脉注射5~10 mg/次罗库溴铵以维持肌肉松弛,15~25 mg/次麻黄碱和1~2 mg/次阿托品以维持血液动力学稳定。在麻醉维持中,调控瑞芬太尼和右美托咪定的静脉输注速率及七氟醚吸入浓度。术后切口采用3~5 ml盐酸利多卡因进行局部浸润麻醉,尽量不采用静脉镇痛泵。然后将术后患者送入麻醉恢复室,待清醒后且肌力恢复时送回病房。, 百拇医药(游春枝)
