目的:探讨脑电双频指数(BIS)用于脑损伤患者转归情况预测的应用价值。方法:对内科重症病房脑损伤病例52例,经常规治疗后观察和记录预后,多功能监护系统BIS模式监测BIS水平,同时进行格拉斯哥(GCS)评分。结果:脑损伤清醒、意识障碍、死亡三组不同BIS值患者预后差异具有统计学意义(卡方值11.460,P<0.05)。清醒组、意识障碍组、死亡组患者BIS评分与GCS评分比较差异均具有统计学意义(P<0.01);对52例患者BIS与GCS评分进行线性分析,GIS与GCS具有相关性,r=0.360,P<0.01,Y=-0.587+0.126X。结论:BIS对重症病房脑损伤患者的组织损伤程度及转归具有较好的预测与辅助评价作用,BIS评分越低,患者的脑损伤程度越重,预后越差。
Objective: To investigate the value of using the bispectral index (BIS) in predicting the outcome of patients with brain injury. Methods: Fifty-two cases of traumatic brain injury in medical intensive ward were observed and recorded after routine treatment. BIS was monitored by BIS model in multi-function monitoring system and Glasgow score (GCS) was also performed. Results: There were significant differences in prognosis between the three groups with different BIS values (chi square value 11.460, P <0.05) in patients with conscious brain injury, impaired consciousness and death. There were significant differences between BIS score and GCS score in conscious group, unconscious group, and death group (P <0.01). The linear correlation between BIS and GCS score was found in 52 patients. There was a correlation between GIS and GCS (r = 0.360 , P <0.01, Y = -0.587 + 0.126X. CONCLUSION: BIS has good predictive and auxiliary evaluation on the degree of tissue injury in patients with severe ward brain injury and prognosis. The lower the BIS score, the more serious the brain damage is and the worse the prognosis is.
