This needs to be specifically analyzed based on the patient's condition.

In most cases, a second subarachnoid hemorrhage is often very severe and generally considered beyond recovery. The patient is likely to die or, even if their life is saved, they may suffer from serious sequelae. They may remain in a prolonged coma, exist in a vegetative state, or suffer from severe impairments that prevent them from caring for themselves.

However, some patients are luckier. With a second or third subarachnoid hemorrhage that is not very severe, if it is recognized early and treated promptly, and if the primary diseases are managed and aneurysms are treated with embolization or craniotomy for clipping, the outcomes can be favorable. In such cases, complete recovery is possible, and the patient can be saved.

Subarachnoid hemorrhage causes increased intracranial pressure.

Patients with subarachnoid hemorrhage often have very high intracranial pressure. The main reason for the rise in intracranial pressure is that after the hemorrhage, the bloody cerebrospinal fluid usually stimulates nerves and blood vessels within the brain, which can lead to edema, such as vascular edema and neural edema, thereby gradually increasing the intracranial pressure. Sometimes, and relatively infrequently, the increase in cranial pressure is not significant. However, if the volume of subarachnoid hemorrhage is very large, the intracranial pressure can rise substantially, leading to symptoms like severe nausea, vomiting, and headache, and in severe cases, there can be significant disturbances in consciousness. Additionally, patients with subarachnoid hemorrhage may sometimes experience obstructive or communicating hydrocephalus, which can also lead to increased cranial pressure.

Is it normal to have a fever with subarachnoid hemorrhage?

It is normal for patients with subarachnoid hemorrhage to develop a fever, but this must be assessed in conjunction with the patient’s body temperature and overall condition. Sometimes, the amount of bleeding in the subarachnoid space is small and may cause mild fever, mainly due to the irritation of the nerves by bloody cerebrospinal fluid. In other cases, when there is a lot of bleeding, it may cause high fever, possibly central fever, which requires specific measures to reduce the body temperature, such as pharmacotherapy, applying ice packs, or using hypothermia therapy devices. Additionally, some patients develop a fever three to five days after the subarachnoid hemorrhage, which might indicate a secondary infection, such as lung or urinary tract infections, necessitating anti-infection treatment.

Subarachnoid hemorrhage nausea and vomiting how to treat

Patients with subarachnoid hemorrhage experiencing nausea and vomiting can still be treated. Firstly, symptomatic treatment should be conducted, which can include using gastric mucosal protectants and antiemetic medications to effectively alleviate symptoms. Additionally, subarachnoid hemorrhage, nausea, and vomiting are often caused by increased intracranial pressure. In such cases, using mannitol or furosemide to dehydrate can reduce intracranial pressure. Once the intracranial pressure decreases, the symptoms of nausea and vomiting can be greatly improved and alleviated. Of course, some patients may also have complications such as hydrocephalus or intracerebral hematoma. In these cases, surgical interventions like craniotomy for hematoma removal or aneurysm clipping may be necessary, which can gradually relieve and improve the symptoms of nausea and vomiting. Beyond symptomatic treatment, it is also necessary to treat the underlying primary disease, addressing causes such as aneurysms or vascular malformations.

What to pay attention to during the recovery period of subarachnoid hemorrhage?

Patients with subarachnoid hemorrhage generally have aneurysms or arteriovenous malformations as the cause. After onset, the main symptom is usually headache, with positive meningeal irritation signs found during examination, but no signs of neurological function deficit. Therefore, during the recovery phase, patients generally do not show positive neurological signs and have good limb mobility. It is only necessary to take precautions against the cause of the disease. For instance, if the patient's cerebral aneurysm has not been surgically treated, there could be a risk of rebleeding. Patients should minimize physical activity, rest in bed as much as possible, and avoid aneurysm rupture. Regular blood pressure control is also essential. If the cause has already been addressed, there are not many precautions needed. Additionally, long-term administration of nimodipine is necessary to prevent delayed cerebral vasospasm, generally recommended for a period of four to six months. (Medication should be used under the guidance of a doctor based on specific conditions.)
