The treatment of subarachnoid hemorrhage primarily aims to prevent rebleeding, vasospasm, hydrocephalus, and other complications, reducing mortality and disability rates. During the acute phase, keep the patient's head in a raised position, lying on their side, and provide dehydration, sedation, and pain relief; absolute bed rest; monitor blood pressure; and when bleeding is significant, undertake ventricular puncture for drainage. Patients with subarachnoid hemorrhage should generally be admitted to the ICU, monitoring vital signs and changes in neurological signs, ensuring airway patency, maintaining stable respiratory and circulatory functions, resting quietly, avoiding emotional agitation, ensuring smooth bowel movements, and for patients with increased intracranial pressure, appropriately restricting fluid intake.
