【摘要】：目的观察脑电双频指数(BIS)监测老年患者靶控输注和手控输注丙泊酚复合瑞芬太尼静脉全身麻醉状态的应用效果。方法将2014年5月至2015年9月行复合静脉全身麻醉下直肠癌根治手术治疗的患者337例,根据随机自愿原则分为靶控输注组(T组)168例和手控输注组(M组)169例,记录两组进入手术室后约30 min即麻醉开始前(T_0)、置入喉罩时(T_1)、手术开始时(T_2)、手术开始后60 min(T_3)、手术停止时(T_4)、拔除喉罩时(T_5)BIS值,术后第1天和第4天随访两组患者有无术中知晓情况发生。结果 T组在T_2,T_3,T_4的BIS值明显低于M组,差异有统计学意义(P0.05);T组术中出现知晓的发生率低于M组,差异有统计学意义(P0.05)。结论 BIS监测指导静脉全身麻醉对降低术中知晓发生率有积极作用,值得临床推广。
[Abstract]:Objective to observe the bispectral index (BIS) of EEG. Objective controlled infusion and manual infusion of propofol combined with remifentanil were used to monitor the efficacy of general intravenous anesthesia in elderly patients. Methods from May 2014 to September 2015, rectal cancer roots were treated with combined intravenous anesthesia. 337 cases were treated by operation. According to the random voluntary principle, 168 patients were divided into target controlled infusion group (n = 168) and manual infusion group (n = 169). About 30 min after entering the operating room, the two groups were recorded. When a laryngeal mask is placed, there will be a tit at the beginning of the operation, 60 minutes after the operation begins, and T4 at the end of the operation. When the larynx mask is removed, the value of T5 BIS will be removed. Results the BIS of group T was significantly lower than that of group M in the first and fourth days after operation. The difference was statistically significant (P 0.05). The incidence of intraoperative awareness in group T was lower than that in group M. the difference was statistically significant (P 0.05). Conclusion BIS monitoring and guidance of intravenous general anesthesia has a positive effect on reducing the incidence of intraoperative knowledge. It is worth popularizing in clinic.
