Objective:To carry out bedside EEG monitoring of patients with coma for many times , and analyze the results of multiple EEG ;To discuss the value of brain function in patients with coma and the possibility of recovering consciousness of the patients and then evaluate the accuracy of prognosis so as to provide evidence for clinical evaluation and prognosis of coma brain function .Methods :One hundred and ninty-two patients with coma in ICU ,EICU and NICU wards were selected and measured by bedside long-range EEG monitoring system .The datum were recorded every other day and analyzed .Results:Of 192 patients there were 57 cases with light coma 37 cases with moderate coma 98 cases with deep coma . Of 114 cured cases there were 49 cases originally with light coma and 32 cases with moderate coma 33 ca-ses with deep coma .78 cases died .According to the coma scale of patients'consciousness disturbance and electroencephalogram(EEG) outcome linear correlation ,the correlation coefficient r=0 .79 ,P<0 .01 .The EEG outcome of the 192 patients with coma was statistically significant .Conclusion:EEG monitoring can effectively judge the possibility of consciousness recovery of patients with coma and has important guiding significance to determine the patient's clinical prognosis .%目的:对昏迷患者进行多次床旁脑电图监测,并将多次描记结果进行分析与对比,探讨其在昏迷患者脑功能演变过程中意识恢复的可能性,以及评价预后的准确率,旨在为临床评估昏迷患者脑功能及预后提供客观依据.方法:选择ICU、EICU和NICU病房中的昏迷患者192例,应用床旁长程脑电监护系统描记脑电图,所有病例每间隔一天记录一次,对多次记录结果进行分析对比.结果:入选的192例患者中浅昏迷57例、中度昏迷37例、深昏迷98例;总共治愈114例,其中浅昏迷49例、中度昏迷32例、深昏迷33例;死亡78例.意识障碍患者的昏迷程度分级与脑电图转归进行线性相关分析,相关系数r=0.79,P<0.01.所观察的全部192例意识障碍患者经过多次长程脑电图追踪随访后昏迷程度与患者的预后有统计学意义.结论:床旁脑电图监测能够有效判断昏迷患者意识恢复的可能性 ,对判断患者的临床预后有重要指导意义.
