脑电双频指数对急诊意识障碍患者转归的预测价值

Predictive Value of Bispectral Index in Emergency Patients with Consciousness Disorder

目的探讨脑电双频指数(bispectral index,BIS)在急诊意识障碍患者转归中的预测价值。方法回顾性分析我院2018年1月至2019年1月经我院急诊收治的意识障碍患者42例,其中男性26例,女性16例,分为生存组和死亡组。应用BIS动态观察患者的意识障碍程度,同时进行Glascow昏迷评分(GCS)、急性生理学与慢性健康状况评分系统(APACHEⅡ)评分记录。分析BIS和GCS、APACHEⅡ评分的相关性,以及评估BIS预测价值。统计学软件采用SPSS17.0。结果死亡组BIS值和GCS评分低于生存组,APACHEⅡ评分死亡组高于生存组,差异均有统计学意义(P>0.05)。BIS与GCS呈显著正相关(r=0.669,P值<0.001),BIS与APACHEⅡ呈显著负相关(r=-0.802,P值<0.001)。30 d患者预后因素分析可见预测能力分别为:BIS(AUC=0.939;95%可信区间:0.852~1.0;截点值33.8)。结论脑电双频指数对预测急诊意识障碍患者转归有重大价值。

Objective To explore the predictive value of bispectral index(BIS)in emergency patients with consciousness disorder.Methods A retrospective analysis was made of 42 patients with consciousness disorder admitted to our hospital from January 2018 to January 2019.Among them,26 were males and 16 were females.They were divided into survival group and death group.BIS was used to observe the degree of consciousness disorder,and Glascow Coma Score(GCS),Acute Physiology and Chronic Health Score System(APACHEⅡ)were recorded.The correlation between BIS and GCS,APACHEⅡscores was analyzed,and the predictive value of BIS was evaluated.The statistical software was SPSS17.0.Results The BIS value and GCS score of the death group were lower than those of the survival group,and the APACHEⅡscore of the death group was higher than that of the survival group,with statistical significance(P>0.05).BIS was positively correlated with GCS(r=0.669,P<0.001),while BIS was negatively correlated with APACHEⅡ(r=-0.802,P<0.001).The prognostic factors of 30-day patients were BIS(AUC=0.939;95%confidence interval:0.852-1.0;cut-off value:33.8).Conclusion BIS is of great value in predicting the outcome of emergency patients with consciousness disorder.
