The probability of awakening from brainstem hemorrhage is generally only about 30%-45%, which is relatively low. This is because the brainstem is the most important center for circulation and respiration in the human body, as well as the awakening center. Awakening can be divided into two stages: the first stage is being able to eat, drink, and defecate independently; the second stage is being able to communicate normally with others. However, patients with brainstem hemorrhage, due to severe damage, may not even reach the first stage, meaning they may not even survive, and reaching the second stage is even more difficult. Therefore, it is essential to clearly understand the specific circumstances at the time, as awakening is generally a very unlikely event.

The acute phase of brainstem hemorrhage lasts for several days.

The acute phase of brainstem hemorrhage generally lasts about two to three weeks, or 14 to 21 days, but it also needs to be specifically assessed based on the different conditions of the patient. If the hemorrhage in the brainstem is relatively severe and located in an important functional area, then the critical period may be appropriately extended. For example, if the hemorrhage is in the medulla oblongata and has already caused respiratory and circulatory failure, as well as unstable vital signs and a comatose state, then the critical period could even reach about one to two months, because it is often necessary to use a ventilator to assist breathing, and the patient's comatose state does not allow for full consciousness. However, for some brainstem hemorrhages, such as a small hemorrhage in the pons that only causes the clinical symptom of headache in the patient, the critical period is generally no more than two weeks. Thus, each patient's condition is different.

Is it normal to have a high fever with brainstem hemorrhage?

Patients with brainstem hemorrhage who develop a high fever may have several possible causes. Firstly, it might be due to absorption heat, but in such cases, the body temperature generally does not exceed 38.5 degrees Celsius. If there is recurrent fever, accompanied by coughing, expectoration, yellow and sticky sputum that is difficult to expel, it is mostly considered likely to be a pulmonary infection, in which case the body temperature generally exceeds 38.5 degrees Celsius, and high fever occurs. Additionally, it is important to note that once fever occurs, antipyretic medications should be administered to the patient to help lower the body temperature. Physical methods such as using warm water or rubbing alcohol for baths can also be used to reduce the temperature.

How long does it take for the fever to subside after a brainstem hemorrhage?

For patients with brainstem hemorrhage, it is common to develop high fever after the bleeding, where the body temperature often exceeds 38.5℃. There are many reasons for the occurrence of high fever. It can be considered that the presence of an intracerebral hematoma compresses the hypothalamic temperature set point, causing abnormalities in the set point function and leading to central fever, with temperatures often reaching 39℃ or even higher than 40℃. At this time, the use of antipyretic drugs alone generally has poor therapeutic effect. It often requires the effective absorption of the intracerebral hematoma for the body temperature to gradually return to normal. Another situation, considering the occurrence of pulmonary infection, it is necessary to promptly provide patients with antibiotics for effective treatment. When the pulmonary infection is effectively controlled, the body temperature will also gradually decrease.

How to prevent brainstem hemorrhage?

To prevent brainstem hemorrhage, it is first recommended that in daily life, if there are underlying diseases such as hypertension or diabetes, it is advisable to keep the patient's blood pressure and blood sugar levels within a stable range. Monitor blood pressure in the morning and evening, and take antihypertensive medication on time. When high blood pressure is detected, you should promptly visit the department of cardiology at the local hospital and ask the doctor to help regulate blood pressure to ensure its stability. In addition, it is recommended to develop good lifestyle habits in daily life, such as regular eating and sleeping, avoiding overwork, exhaustion, mental stress, and staying up late, while maintaining adequate sleep and good lifestyle habits to help prevent brainstem hemorrhage.

How is brainstem hemorrhage caused?

There are many causes of brainstem hemorrhage, and in most clinical cases, it is seen in patients who have a history of hypertension and diabetes, and whose blood pressure and blood sugar have not been well controlled. Over time, due to prolonged high blood pressure or high blood sugar, arteriosclerotic changes occur in the vessels, and the vessels' own contractile function gradually declines. Under certain triggering factors, such as fatigue, exhaustion, mental stress, or excessive emotional excitement, the patient may experience transient dilation of the vessels, exceeding their regulatory capacity, which can lead to brainstem hemorrhage. Once brainstem hemorrhage occurs, it often leads to significant disturbances in consciousness within a short period, manifested as stupor or coma.
