How many days are at risk for subarachnoid hemorrhage?

Subarachnoid hemorrhage is at risk for about two weeks after it occurs, and longer in patients with severe subarachnoid hemorrhage.
Rupture of intracranial aneurysms is the most common cause of subarachnoid hemorrhage. Re-rupture of the aneurysm and bleeding, cerebral vasospasm due to subarachnoid hemorrhage, hydrocephalus, and epilepsy are all important factors that contribute to the death of the patient. The peak of these complications is usually within two weeks after the onset of the disease, i.e., the danger period, which is extended accordingly in severely ill patients.
It is generally recommended that patients with subarachnoid hemorrhage be placed on absolute bed rest for four to six weeks, that emotions be controlled, and that the patient’s blood pressure be regulated. The prognosis for subarachnoid hemorrhage is poor, with a mortality rate of 45%. About 20% of untreated patients die from rebleeding.
Therefore, patients with subarachnoid hemorrhage should be admitted to the hospital in a timely manner to identify the cause of the hemorrhage, and under the guidance of the doctor, treatment should be given to prevent rebleeding and reduce the occurrence of complications, thereby reducing the risk of death and enabling the patient to pass through the dangerous period safely.
