Seizures may occur due to a brainstem hemorrhage for several reasons, First, significant edema following a brainstem hemorrhage, combined with the mass effect of the hemorrhage itself, can lead to substantial compression of the brainstem, potentially resulting in tonic seizures. Second, the irritation from the hemorrhage could trigger symptomatic epilepsy, with the patient possibly experiencing partial new epileptic seizures that evolve into generalized tonic-clonic seizures. Third, the brainstem hemorrhage might cause high fever, which could induce febrile convulsions, also leading to seizures. Fourth, the treatment of brainstem hemorrhage often involves the use of high doses of diuretics. If severe dehydration occurs, it can lead to a state of excessive dehydration, electrolyte imbalance, and hyperosmolarity; high sodium levels might also trigger seizures.

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.

How is brainstem hemorrhage treated?

Brainstem hemorrhage is extremely dangerous and must be treated as soon as possible. The treatment plan mainly includes: the patient must rest in bed, avoid emotional stimulation, ensure smooth bowel movements, and must strengthen turning over and patting the back to prevent serious complications such as bedsores and pulmonary infections. In terms of medication, it mainly involves providing drugs that protect brain cells and nourish brain nerves. Additionally, because patients with brainstem hemorrhage have high intracranial pressure, it is necessary to administer dehydrating drugs to reduce intracranial pressure. Moreover, once the patient's vital signs stabilize, treatments such as acupuncture and rehabilitation training are needed to promote the recovery of neural functions. If the patient experiences respiratory failure, it is necessary to promptly use a ventilator for treatment. Furthermore, patients with brainstem hemorrhage who are bedridden for a long period can develop complications such as pulmonary infections and urinary system infections. If these complications occur, timely use of antibiotics is necessary to control the complications.

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 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.)

How to exercise balance after brainstem hemorrhage?

For patients with brainstem hemorrhage who exhibit significant limb motor dysfunction and reduced sense of balance, it is recommended to seek treatment at a well-known local tertiary hospital. Experienced rehabilitation therapists should assess the current condition and develop an individualized rehabilitation exercise plan based on the patient's condition. Gradually, they should begin exercise training, including training for limb balance capabilities. Patients who actively and effectively engage in exercise therapy often achieve good therapeutic effects, with gradual restoration of balance and strengthening of limb motor function, achieving relatively satisfactory treatment outcomes.
