Abstract:
The factors which were related to the neurological condition were analyzed in 233 cases of subarachnoid hemorrhage. Bivariate analysis and multiple(binomial)logistic regression analysis were performed as for Hunt & Kosnik grade, modified Rankin Scale at discharge and modified Rankin Scale in the out-patient department to detect the factors which were related to the neurological condition. Hematoma-filled intraventricular hemorrhage, intracerebral hemorrhage with midline shift, acute subdural hematoma and aneurysm of the vertebrobasilar system were the representative factors which caused poor neurological condition. Hunt & Kosnik grade was poor when rebleeding occurred or hematoma was formed in the sylvian fissure. Hunt & Kosnik grade and modified Rankin Scale at discharge tended to be poor in the cases with acute hydrocephalus. The elevation of intracranial pressure was the major factor in neurological deterioration.
