摘　　要：目的探讨开颅术后早期脑电双频指数（BIS）监测对患者远期意识状态预测的准确性,指导护士早期判断患者意识状态。方法对63例开颅术后延迟苏醒拔管患者,记录术后6 h内每小时BIS监测值（BISmax）、道格拉斯昏迷量表中的语言或疼痛刺激体动反应评分（GCS-M）及术后24 h意识状态。根据患者术后24 h是否清醒分组,计算两组BISmax、GCS-M及BISmax对术后24h意识障碍的预测概率（PK）。结果术后24 h清醒患者57例,未清醒6例;清醒者GCS-M评分均为6分,术后6 h内BISmax预测术后24 h意识障碍的PK值为0.69~0.86。结论监测BIS可作为开颅术后患者意识状态的辅助预测方法。Objective To explore prediction accuracy of bispectral index（BIS） monitoring used to detect long-term postoperative consciousness in patients after craniotomy,and to help nurses assess patients′consciousness early.Methods Sixty-three patients who had delayed awakening and prolonged extubation after craniotomy were enrolled in the study.The BIS values,responses to verbal and painful stimuli were recorded every hour for 6 hours after operation,and the consciousness was assessed at 24th postoperative hour.Prediction probability（PK） was calculated to determine the probability of BIS in predicting conscious disturbance at 24th postoperative hour.Results At 24th postoperative hour,57 were fully conscious,6 were disorientated or in a coma.The values of GCS-M scored 6 points in conscious patients at each time point.The PK ranged from 0.69 to 0.86 within 6 postoperative hours.Conclusion BIS monitoring can be used as an for predicting consciousness after craniotomy adjuvant method.
