摘　　要：目的观察苏醒期脑电双频谱指数（BISawake）与术后认知功能的关系。方法 100例60~75岁、ASAⅠ~Ⅱ级、行下腹部手术的老年患者,采用全静脉麻醉（丙泊酚、瑞芬太尼和罗库溴氨）。术中BIS控制在40~60。手术前后采用国际术后认知功能障碍研究协作组（ISPOCD）推荐的系列测试量表进行认知功能评估。结果 8例患者由于不愿合作或出现严重并发症退出。BISawake与睁眼时间和拔管时间呈负相关。68例患者BISawake大于65（A组）,24例BISawake小于65（B组）,B组词语记忆和词语延迟记忆两项评分术前术后差值与A组相比增大（P〈0.05）。结论 BISawake降低的患者可能预示着术后词语相关认知功能减退。Objective To observe the relationship of awake bispectral index（BISawake） and the postoperative cognitive dysfunction（POCD）.Methods 100 patients aged 60~75 years with ASA statusⅠ~Ⅱ,underwent elective lower abdominal surgery with intravenous anesthesia（propofol,remifentanyl and rocuronium）.The BIS was adjusted in 40~60 during the surgery.Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction（ISPOCD）.Results 8 patients withdrew for unwilling or serious complications.The BISawake was more than 65 in 68 patients（group A）,and less than 65 in 24 patients（group B）.The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A.Conclusion Lower BISawakemay be associated with the decline of postoperative cognitive function.
