Abstract
Three hundred eighty-three cases of subarachnoid hemorrhage due to the rupture of the aneurysm were experienced since 1978. Of these cases 129 (34%) had bleeding twice or more. The period of rebleeding was investigated. It occurred within 6 hours after the first stroke in 48 cases(37%), and the total of rebleeding within 24 hours amounted to 57 cases(44%). Rebleeding within 6 hours showed high frequency.
One hundred eighty-one cases were admitted to our clinic within 6 hours after the first stroke, of whom 57 cases(31%) had rebleeding. On these 57 cases it was studied whether rebleeding occurred before or after admission. It occurred before admission in 19 cases(33.3%) and after that in 36 cases (66.6%). Rebleeding after admission were recognized in various situations, such as immediately after the arrival to our clinic, during consultation, or during CT examination or angiography. The deterioration due to rebleeding under medical facilities must be prevented to the best of our ability. Though our attention is given to sedation (Barbiturate), the control of blood pressure and intracranial pressure, the condition at consultation, and so on, there are still many difficult problems.
