Brainstem hemorrhage itself is a very dangerous disease. Patients with a large amount of bleeding generally find it difficult to recover and may even result in a vegetative state or death.

The occurrence of fever in brainstem hemorrhage mainly has two reasons. First, brainstem hemorrhage can cause central fever, which is mainly due to damage to some autonomic nerves, leading to problems with the body's temperature regulation function. If central fever occurs, it is quite dangerous and indicates a poor prognosis, necessitating active physical cooling.

Secondly, patients with brainstem hemorrhage are often in a comatose and bedridden state, making them highly susceptible to various complications, such as pulmonary infections and urinary system infections. If fever arises due to these infections, it also indicates a poor prognosis, with relatively high mortality and disability rates.

Overall, the occurrence of fever in patients with brainstem hemorrhage is quite dangerous and indicates a poor prognosis.

How does a brainstem hemorrhage clot get absorbed?

For patients with brainstem hemorrhage, edema generally enters the edema phase within 24 to 48 hours, and then gradually transitions into the absorption phase. During this period, it is first necessary to provide the patient with medications that enhance brain function, promote blood circulation and remove blood stasis, and nourish the nerves for treatment. At the same time, it is important to monitor changes in the patient's condition, and regularly perform a head CT scan to dynamically observe the changes in cerebral hematoma. In most cases, it is necessary to prevent various complications or concurrent diseases. If there is an abnormality in coagulation function, it is advisable to administer hemostatic drugs for treatment during the acute phase. However, once the patient's condition stabilizes, use medications that improve cerebral microcirculation and promote blood circulation and remove blood stasis for treatment.

How to rehabilitate from brainstem hemorrhage?

For patients with brainstem hemorrhage, it is often recommended during the acute phase to treat them with medications for hemostasis, brain enhancement, nerve nutrition, dehydration to reduce intracranial pressure, and inhibition of gastric acid. It is also important to actively treat complications and comorbidities caused by the brainstem hemorrhage. For these patients, when the condition is stable, appropriate rehabilitation exercises should be carried out. For patients with hemiplegia or aphasia, rehabilitation exercises can be done on the affected limbs, and speech rehabilitation training can help improve current conditions of hemiplegia and aphasia. Additionally, for these patients, active and passive massage of the limbs should be initiated early to prevent muscle atrophy and joint stiffness.

Can brainstem hemorrhage be cured?

Brainstem hemorrhage is a very dangerous disease with poor prognosis and high mortality rate. Although the brainstem is very small, it contains almost all vital neurological functions. Once hemorrhage occurs, it can cause severe neurological dysfunction, and even lead to the patient's death due to cessation of heartbeat and breathing in a short period. So, can brainstem hemorrhage be cured? It mainly depends on the location of the hemorrhage, the amount of bleeding, and the clinical symptoms. Patients with less bleeding, hemorrhages closer to the upper end of the brainstem, and milder clinical symptoms have a better chance of recovery. However, those with more extensive bleeding, hemorrhages closer to the lower end of the brainstem, and more severe clinical symptoms have a lesser likelihood of recovery.

Rehabilitation of sequelae of brainstem hemorrhage

For patients with brainstem hemorrhage, there may be certain sequelae, such as obvious motor dysfunction of the limbs, like hemiplegia on one side. Additionally, some patients may also lose speech functions, manifested as motor aphasia or mixed aphasia. Most patients are likely to experience a decline in memory and have difficulty swallowing, often accompanied by coughing when drinking water. For these patients, post-recovery rehabilitation treatment becomes particularly crucial. During the recovery phase, effective rehabilitation exercises should be provided for the sequelae, such as rehabilitation exercises for motor functions of the affected limbs and speech function exercises.

Causes of brainstem hemorrhage

The causes of brainstem hemorrhage mainly include the following aspects: The first aspect is hypertension; arteriosclerosis is the most important cause of brainstem hemorrhage because prolonged high blood pressure and continuous impact of blood flow easily lead to damage and disease of the blood vessels, forming small aneurysms. These aneurysms eventually rupture, causing brainstem bleeding. The second aspect is vascular malformations in the brainstem area, which are another major cause of bleeding. Most patients under 40 with normal blood pressure and no coagulation disorders can find vascular malformations in the brainstem area after undergoing DSA examinations following brainstem hemorrhage. The third aspect is heavy drinking leading to increased blood pressure, impaired liver function, abnormal coagulation, etc., ultimately causing bleeding in the brainstem area.
