The brainstem is the center of human life, controlling vital functions such as breathing, circulation, heart rate, and blood pressure. Once bleeding occurs, patients often experience unstable vital signs, deep coma, and can die from brain function failure within a short period. Previously, it was believed that the brainstem was a no-go zone for surgery, and treatment for brainstem hemorrhage was primarily conservative medical therapy. However, with the continuous improvement of medical technology, neurosurgery departments in many top-tier hospitals have made significant achievements in minimally invasive or open surgeries for brainstem hemorrhages. Therefore, surgery for brainstem hemorrhage is not impossible and can be considered under specific circumstances.

Is there any sensation before brainstem hemorrhage?

The most common cause of brainstem hemorrhage is generally hypertension. The mechanism by which hypertension causes bleeding is chronic long-term hypertension, leading to hyaline degeneration of the small arterial walls. Under the force of blood flow, these walls are prone to bulging, leading to the formation of microaneurysms. When blood pressure fluctuates sharply, especially when there is a significant increase, it can cause these microaneurysms to rupture, leading to bleeding. Thus, if there are noticeable symptoms before the hemorrhage, they are mostly due to a sudden increase in blood pressure. Patients often experience dizziness or headaches, sometimes along with blurred vision, and may be accompanied by nausea and vomiting, but most patients may not feel any abnormalities before the bleeding occurs.

Signs before death from brainstem hemorrhage

For patients with brainstem hemorrhage, if the patient's life is in danger, they often exhibit some special clinical manifestations. For example, the patient may present with apparent consciousness disturbances, characterized by moderate to severe coma states. In this state, the patient is unaware, unable to open their eyes or speak. When subjected to strong painful stimuli on their limbs, there is often no significant response, or it may just cause muscle twitching. Additionally, patients with brainstem hemorrhage may exhibit severe disturbances in vital signs as they approach death, characterized by shallow, rapid, and weakening spontaneous breathing, sometimes even ceasing, often requiring ventilator support. Also, difficulty in maintaining blood pressure may lead to a sudden drop in pressure or even shock.

sequelae of brainstem hemorrhage

All the different sequelae of cerebral hemorrhage can potentially occur after a brainstem hemorrhage. This is because the brainstem is a critical link between the brain and the body, acting as the command center within the headquarters. Of course, whether sequelae will occur and which ones will occur after a brainstem hemorrhage primarily depends on the amount of bleeding and the location of the bleed. If the bleeding in the brainstem is minor and occurs in a less critical area, the sequelae are usually minimal, and some people might not experience any sequelae at all. However, if there is substantial bleeding in the brainstem and the area affected is crucial, the patient may remain comatose for a long period. Even if they are revived and regain consciousness, they may suffer from severe functional impairments and experience numerous sequelae.

What causes fever from brainstem hemorrhage?

Patients with brainstem hemorrhage experience fever generally for the following three reasons: First, infection. Patients with brainstem hemorrhage often have disturbances of consciousness and dysfunction of the throat, and are bedridden, which frequently leads to aspiration pneumonia and hypostatic pneumonia. This is due to weakened ability to clear phlegm, as well as choking caused by saliva and feeding. Additionally, infections can easily occur in the gastrointestinal tract, urinary tract, and from skin pressure sores. Second, abnormalities in the temperature set point cause central hyperthermia. In patients with brainstem hemorrhage, the temperature regulation center is damaged. If the temperature regulating center sets the body temperature above 38 degrees Celsius, it often persists and cannot be reduced, and medications are poorly effective in lowering the temperature, necessitating the use of ice packs for physical cooling. Third, patients with brainstem hemorrhage often use large doses of diuretics. Dehydration after diuretic use can put patients in a state of excessive dehydration. If rehydration therapy is not adequately managed, dehydration fever can easily occur.

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.
