Study on special pattern of the EEG-RAWOD of acute massive ischemic infarction / 中华神经科杂志

ABSTRACT

Objectives To study a special pattern of electroencephalogram (EEG),regional attenuation without Delta in massive cerebral ischemic infraction and evaluate its clinical value.Methods All the 47 cases diagnosed as massive cerebral infraction were continuously observed and evaluated in the period of 2004 to 2006 for EEG,short-latency somatosensory evoked potential (SLSEP).Glasgow coma scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS) were also rated.EEG monitoring was performed every 1 to 3 day,but at least one time for patient with deteriorated condition.The outcome was evaluated with Glasgow outcome scale (GOS).Results 47 cases were performed 70 times of EEG all together,among whom 32 cases (68.1%) showed RAWOD in EEG.The positive rate of RAWOD was 76.9% within 24 hours of onset,but it was 28.6% in CT in the same time.The GCS and NIHSS of two groups had significant differences (P
