目的分析比较全凭静脉麻醉与吸入麻醉对老年患者术后认知功能影响。方法选取我院收治的45例进行腹部手术患者为研究对象，年龄在59~71岁，按照随机表法将其分为三组，分别为A组(异氟烷组)、B组(七氟烷组)、C组(全凭静脉组)。将三组患者的结果进行比较分析。结果三组患者的性别、年龄、手术与麻醉时间、输血与出血量等的差异不具有统计学意义，术后拔管与睁眼时间A组比B组长，差异不具有统计学意义。而C组的拔管与睁眼时间明显比A、B两组都短，差异具有统计学意义。结论吸入麻醉和全凭静脉麻醉两种麻醉方法都适于临床老年手术麻醉，都能够在手术后短时期减退患者认知，但全凭静脉麻醉的恢复时间比吸入麻醉的恢复时间短，恢复效果好。“,”Objective Compare and analyse the influence of total intravenous anesthesia and inhalation anesthesia on postoperative cognitive function in elderly patients. Methods Select our hospital 45 patients were abdominal operation as the research object, aged between 59 and 71 years old, randomly divided into 3 groups, groupA(isofluranegroup), groupB (sevoflurane group), groupC(intravenous group). Analyse and compare the results of three groups. Results The patients in the three groups of gender, age, operation time, anesthesia time, blood transfusion and bleeding amount had no statistical significance ,and the time of eyes open in group A is longer than group B ,Time to extubation after surgery group A is longer than group B,But the dif erence is no statistical y significant. But eyes open time and extubation time in group C was significantly shorter than the group A and group B, the dif erence had statistical y significant.Conclusion Inhalation anesthesia and total intravenous anesthesia are both suitable for elderly operation patients, al can decrease cognitive function in the short period after operation , but total intravenous anesthesia recovery time is shorter than inhalation anesthesia . recovery ef ect is bet er.
