Subarachnoid hemorrhage is a rather dangerous disease that develops very quickly, causing severe headaches, nausea, vomiting in patients, and this disease has a high probability of bleeding, potentially causing some cerebral vasospasm, leading to secondary thrombus formation. Besides prompt treatment and identifying the cause, such as clipping an aneurysm, nursing measures are also very important. Common nursing measures mainly include: First, it is essential to educate the patient to stay in bed and rest absolutely, as premature activity may cause the aneurysm to rupture and rebleed. Second, the patient must be instructed to maintain smooth bowel movements and a stable emotional state to prevent increased intracranial pressure and rebleeding due to emotional excitement or constipation. Third, the patient should be encouraged to drink more water and be given sufficient fluids to prevent cerebral vasospasm and low perfusion effects. Other nursing measures include stabilizing the patient's mood and providing sedation when necessary.
