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.

Is brainstem hemorrhage serious?

Brainstem hemorrhage is caused by the rupture of small blood vessels in the brainstem, with common causes including hypertension, cerebral arteriosclerosis, vascular degeneration, and microaneurysms of vessels. Clinically, it manifests as sudden onset of consciousness impairment, confusion, coma or deep coma, accompanied by disorders of limb sensory and motor functions, eye movement disorders, and unstable vital signs, among others. If the hemorrhage occurs in the medulla, it can cause death by stopping the patient's heartbeat and breathing within a short period. Brainstem hemorrhage is a severe condition in neurology, and treatment focuses on bed rest to stop bleeding, reducing intracranial pressure, and treating complications. Despite advances in modern medicine, medical professionals often find themselves powerless in the face of many patients with brainstem hemorrhage. For brainstem hemorrhages with more than three milliliters of blood, most patients ultimately succumb to the condition. Therefore, brainstem hemorrhage is a very serious disease with a very high mortality rate in clinical settings.

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.

What should not be eaten in case of brainstem hemorrhage?

Firstly, patients with brainstem hemorrhage should avoid eating foods that are difficult to digest. This is because these patients can easily develop acute gastric mucosal lesions, leading to decreased gastrointestinal function. If they consume harder foods, it could increase the burden on their digestive function, which is detrimental to recovery. Secondly, patients with brainstem hemorrhage should also avoid cold items, such as drinking cold beverages or eating ice cream, as these can easily cause diarrhea. Thirdly, patients with brainstem hemorrhage should not eat overly salty foods, such as pickles, salted meat, salted fish, and so on. These items can cause an increase in blood pressure, potentially exacerbating the brainstem hemorrhage. Fourthly, avoid overly greasy foods as they can increase blood lipids, which is also unfavorable for the recovery from a brainstem hemorrhage. Fifthly, patients with brainstem hemorrhage should not smoke or drink alcohol, as these have no beneficial effect on their condition and could instead accelerate the progression of the disease.

Can brainstem hemorrhage be cured?

For brainstem hemorrhages that have already occurred, the patient should be immediately taken to a local hospital. Initially, a cranial CT scan should be performed to determine the location and amount of bleeding in the brainstem. For minor brainstem hemorrhages, it is recommended to first use medication for treatment. This involves administering drugs that stop bleeding, enhance brain function, promote dehydration, and nourish the nerves, aiding in the gradual cessation of bleeding and the absorption of cerebral hematomas. Most patients can achieve very good treatment outcomes. However, if the brainstem hemorrhage is extensive, it often leads to severe brainstem dysfunction and typically has a poor prognosis.

How to administer first aid for brainstem hemorrhage

For patients with brainstem hemorrhage, once signs of brainstem hemorrhage are detected, the patient should be sent to the local hospital immediately for an emergency head CT scan to help determine the location and severity of the hemorrhage. Due to its special location, brainstem hemorrhage is often difficult to treat surgically in most cases. Once brainstem hemorrhage occurs, the patient should first be transferred to the intensive care unit for close monitoring of vital signs. At the same time, administer medications to stop bleeding, enhance brain function, nourish nerves, promote dehydration, and reduce intracranial pressure, while carefully observing changes in the patient's condition. During treatment, strictly prevent and treat various comorbidities or complications. (Please use medications under the guidance of a professional physician and do not self-medicate.)
