摘　　要：目的分析动态脑电图在重症脑功能损害预后评估中的应用价值。方法方便选取2014年1月—2017年4月该医院住院重症脑功能损害患者84例,采用动态脑电图监测,进行脑电图分级,采用GOS评价患者的预后。结果动态脑电图Ⅰ级者GOS5级、4级、3级、2级、1级分别占32.3%、48.3%、16.1%、3.2%、0.0%,Ⅱ级者分别占30.0%、40.0%、25.0%、5.0%、0.0%,Ⅲ级者分别占11.1%、33.3%、44.4%、5.6%、5.6%,Ⅳ级者分别占0.0%、26.7%、40.0%、20.0%、13.3%,差异有统计学意义(P<0.05)。动态脑电图分级对临床预后的灵敏度80.65%(25/31),特异度50.94%(27/53),符合率61.90%(52/84)。GOS4-5级别的功率FP1(2.56±1.21)、F3(2.63±1.65)、C3(2.83±1.85)低于GOS1-3级FP1(3.63±1.36)、F3(3.26±1.12)、C3(4.19±2.10),功率FP1(3.51±2.13)、F3(2.60±1.14)、C3(3.11±1.24)高于GOS1-3级FP1(4.63±2.63)、F3(3.92±2.13)、C3(4.73±2.15),差异有统计学意义(P<0.05)。结论动态脑电图可作为重症脑功能损伤预后评估方法 ,但其特异度较低,可能存在其他影响预后的因素。Objective This paper tries to analyze the application value of dynamic electroencephalogram in the prognosis of severe brain impairment assessment.Methods From January 2014 to April 2017,the hospital with severe cerebral dysfunction in patients with 84 cases,using dynamic EEG monitoring,EEG classification,prognosis evaluation of patients with GOS.Results The AEEG in grade I of grade GOS5,grade 4,grade 3,grade 2,grade 1 accounted were 32.3%,48.3%,16.1%,3.2%,0.0%,grade II accounted for 30.0%,40.0%,25.0%,5.0%,0.0%,grade III accounted for 11.1%,33.3%,44.4%,5.6%,5.6%,grade IV accounted for 0.0%,26.7%,40.0%,20.0%,13.3%,the difference was statistically significant(P<0.05).The sensitivity of dynamic electroencephalogram on clinical outcomes was 80.65%(25/31),the specificity was 50.94%(27/53),the coincidence rate was 61.90%(52/84).The power of FP1,F3,C3 in GOS4-5 level wave respectively were(2.56±1.21),(2.63±1.65),(2.83±1.85),lower than that of GOS1-3(3.63±1.36),(3.26±1.12),(4.19±2.10),power of FP1,F3,C3 were(3.51±2.13).(2.60±1.14),(3.11±1.24)higher than that of GOS1-3 of(4.63±2.63),(3.92±2.13),(4.73±2.15),the difference was statistically significant(P<0.05).Conclusion EEG can be used as a prognosis evaluation method for severe injury of brain function,but its specificity is low,there may be other prognostic factors.
