Vomiting after brainstem hemorrhage is definitely a serious matter because if the vomiting is caused by a brain-related issue, it is due to increased intracranial pressure. This type of vomiting is characterized as projectile vomiting, which is one of the three major signs of increased intracranial pressure. If the brainstem hemorrhage is extensive, it may cause local stimulation leading to cerebral vascular spasm, or issues such as obstructed brain circulation resulting in increased intracranial pressure and hydrocephalus. This increase in intracranial pressure, especially if prolonged, can lead to brain herniation, which is particularly deadly if it compresses the brainstem. Therefore, this is a very urgent and serious condition that requires immediate attention. Of course, if the vomiting is solely due to other reasons such as gastric retention or improper feeding, that would be a different matter. Projectile vomiting caused by increased intracranial pressure is highly severe.

Is a high fever serious with brainstem hemorrhage?

For patients with brainstem hemorrhage who develop a high fever, it is first necessary to consider that the hemorrhage has affected vital central nervous system functions, leading to central fever. In such cases, the fever typically exceeds 38.5 degrees Celsius, and may even reach high fevers of 39 to 40 degrees Celsius, which are difficult to reduce with ordinary antipyretic drugs. Additionally, some patients with brainstem hemorrhage may also have concurrent lung infections, which can lead to recurrent high fevers exceeding 38.5 degrees Celsius. In such situations, it is advisable to perform a blood test for routine blood work. Furthermore, it is also important to monitor for any local inflammation, auscultate the lungs, and determine if the lung sounds are coarser or if there are any dry or wet rales in both lungs.

How long do you have to stay in the ICU for a brainstem hemorrhage?

The length of stay in the ICU for brainstem hemorrhage depends entirely on the patient's specific condition. Generally, as long as the patient's breathing is stable and they can breathe on their own, and all other vital signs are relatively stable, they can be transferred out of the ICU. However, this depends on the patient's condition at the time. Many patients are admitted to the ICU typically due to poor breathing and lack of autonomous respiration. If a ventilator is used and the results improve, they may then be transferred out. Some may be out in a week, while others may need one to two months. It is also crucial to determine whether they have developed ventilator-associated pneumonia, lower limb venous thrombosis, or other more severe clinical manifestations, so decisions should be made based on these conditions for accuracy.

How to nourish the body after a brainstem hemorrhage

Brainstem hemorrhage is a very dangerous condition. If the bleeding is substantial, the patient may quickly fall into a coma or even die. If the bleeding is less severe, the prognosis might be relatively better. Patients with brainstem hemorrhage typically experience impaired swallowing functions, showing symptoms like inability to swallow food, difficulty in consuming water, and coughing while drinking. Therefore, it is crucial to supplement nutrition. Primarily, a feeding tube can be inserted for hydration and feeding, with the intake mainly consisting of easily digestible foods such as millet porridge, rice porridge, soybean juice, milk, etc. Additionally, it is important to supplement the patient with fresh vegetables and fruits to ensure an adequate supply of vitamin C. Furthermore, high-quality proteins like lean meat and beef should be provided to ensure adequate protein intake for patients with brainstem hemorrhage.

How long does one generally remain unconscious with brainstem hemorrhage?

The duration of coma following brainstem hemorrhage is uncertain. It mainly depends on two factors: The first factor is the amount of bleeding. For brainstem hemorrhages of less than three milliliters, the level of coma is relatively shallow, and some patients may not experience any coma at all, with a high chance of successful resuscitation. For hemorrhages greater than three milliliters, as the amount of bleeding increases, the depth of the patient's coma also deepens, potentially leading to death shortly after the onset of the condition, or the patient might remain comatose for a prolonged period before eventually succumbing. The second factor is whether timely and effective treatment was administered after the brainstem hemorrhage, including medication, necessary surgical interventions, active prevention of complications, and the stabilization of the condition, as well as treatments aimed at promoting awakening, among others.

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.
