摘要目的 比较采用听觉诱发电位指数(AAI)监测与常规监测在芬太尼-丙泊酚全凭静脉麻醉下纤维肠镜诊疗时指数的变化,用以控制适宜的麻醉深度,有效减少麻醉药的用量及其不良反应的发生.方法 选择老年纤维肠镜诊疗患者60例,随机分为观察组(A组)与对照组(B组),每组30例.A组除常规连续监测收缩压(SBP)、舒张压(DBP)、心率(HR)、脉搏氧饱和度(SpO2)外,采用A-Line麻醉/镇静深度监测仪监测AAI值;B组常规连续监测SBP、DBP、HR、SpO2,指导麻醉药物的使用.结果 在芬太尼-丙泊酚静脉麻醉下肠镜检查中监测AAI值,可以实时反应麻醉深度的变化,预测体动反应的发生,及时调控麻醉药物用量以满足手术刺激强度的需要.结论 听觉诱发电位指数在老年无痛纤维肠镜诊疗术中可以指导麻醉用药量,有效减少不良反应的发生.

abstractsObjective According to the change of AAI in fentanil-propofol intravenous anesthesia fiberoptic intestine endoscopy diagnosis and treatment of fiber, compared AAI monitoring with routine monitoring, the study was to reduce the dosage of anesthetics effectively and its side effects, based on appropriaste control of the depth of anesthesia. Methods Sixty patients were randomly divided into group A (observe group) and group B (contrast group), 30 patients per group. Group A, besides SBP, DBP, HR and SpO2, AAI value routine monitored continuously by A-liner to anaesthetize/the calm depth monitor; Group B, SBP, DBP, HR and SpO2 monitored continuously, to guide the use of narcotic drugs. Results Monitoring of AAI values in intestine endoscopy with fentanil-propofol intravenous anesthesia, endoscopic diagnosis and treatment of fiber, which can respond immediately to changes in the depth of anesthesia, forecast the body reaction, and control the narcotic drug use in time to meet the needs of surgery intensity.Conclusions In the elderly analgesia intestine endoscopic diagnose and treatment, AAI can guide anesthetic dosage to reduce effectively its side effects.
