脑电双频指数与昏迷患者GCS评分、GCS-Pittsburgh评分及预后的相关性研究

Study on relativity between bispectral index and GCS,GCS-Pittsburgh,Prognosis

目的探讨脑电双频指数(BIS)监测在判定昏迷患者昏迷程度及预后中的价值。方法选取35例ICU病房格拉斯哥昏迷(GCS)评分≤7分的昏迷患者,昏迷后24 h内行BIS监测,同时行GCS评分和GCS-匹斯堡(Pittsburgh)评分,观察6个月预后。采用Spearman相关分析法分析BIS与GCS评分、GCS-Pittsburgh评分及预后的关系。结果 BIS与GCS评分和GCS-Pittsburgh评分均呈正相关(P<0.01),r分别为0.820、0.873;预后良好者BIS显著高于预后不良者(P<0.01)。结论 BIS监测在评估昏迷患者昏迷程度和判定预后方面具有重要价值。

Objective To investigate the value of bispectral index（BIS） monitorin g in predicting coma degree and prognosis of comatose patients.Methods Thirty-f ive comatose patients whose Glasgow coma scales（GCS） ≤7 were selected from ICU. The record GCS,GCS-Pittsburgh and BIS at the same time within 24 hs after coma were recorded,the prognosis was observed for 6 months.The correlation between BIS and GCS,GCS-Pittsburgh,prognosis were analyzed by Spearman correlation ana lytical method.Results BIS was positively related to GCS and GCS-Pittsburgh（P 0.01）,value of r were 0.820 and 0.873 respectively.BIS in patients with good p rognosis was higher than that with poor prognosis（P0.01）.Conclusion BIS monito ring has significant value in evaluating the comatose degree and prognosis of co matose patients.
