分析８２例蛛网膜下腔出血（ＳＡＨ）患者的脑电图（ＥＥＧ）所见及与临床的关系。ＳＡＨ的ＥＥＧ异常率８３％，异常ＥＥＧ主要有三种形式：以普遍性改变为主（６６％）；广泛性异常伴局灶慢波；局灶性改变。ＥＥＧ中、重度异常以病后２４ｈ～１０天居多（８９％）。ＥＥＧ异常与高血压及腰穿压力增高之间无明显相关性（Ｐ＞０．０５），而与意识障碍及预后明显相关（Ｐ＜０．０５），提示ＥＥＧ可作为判断预后的指标之一。另外ＥＥＧ限局性异常与ＣＴ病灶和脑血管造影也有一定关系。
Analysis of 82 cases of subarachnoid hemorrhage (SAH) patients with electroencephalogram (EEG) seen and the clinical relationship. The abnormal EEG rate of SAH is 83%. There are mainly three forms of abnormal EEG: mainly the general change (66%); extensive abnormality with focal slow wave; focal change. EEG, severe abnormalities to the majority of patients after 24h ~ 10 days (89%). There was no significant correlation between EEG abnormalities and hypertension and lumbar puncture pressure (P> 0.05), but was significantly associated with disturbance of consciousness and prognosis (P <0.05), which suggested that EEG could be used as an indicator of prognosis . In addition, the abnormal EEG limit and CT lesions and cerebral angiography also have a certain relationship.
