Brainstem hemorrhage is one of the most dangerous diseases in neurology because a large amount of brainstem bleeding can cause patients to quickly fall into a coma and lead to death, and there are no highly effective treatment methods available. If the amount of brainstem hemorrhage is not particularly large, the patient may exhibit symptoms of bulbar palsy, which mainly include difficulty swallowing water and food and may also experience limb paralysis, sometimes manifesting as hemiplegia or quadriplegia. Brainstem hemorrhage can also lead to complications such as slurred speech. In addition to bed rest, maintaining emotional stability, and managing complications, it is crucial to control blood pressure, as hypertension is the most common cause of brainstem hemorrhage. Rehabilitation is also very important. The recovery time for brainstem hemorrhage is generally about six months. If recovery has not occurred after six months, the condition is referred to as post-stroke sequelae of brainstem hemorrhage. The optimal period for rehabilitation can begin once the vital signs from the brainstem hemorrhage have stabilized and should continue for up to six months.

How long does it take to wake up from a coma caused by brainstem hemorrhage?

The timing of awakening after a coma caused by a brainstem hemorrhage must be judged based on the situation. As brainstem hemorrhages are relatively severe, there is generally no possibility of awakening if the patient's breathing, heartbeat, and circulation are not stable. If the patient can breathe normally off a ventilator and has a normal heartbeat and other vital signs, and pupil responses are also normal, then typically, they may awaken within one to two weeks. However, recovery times vary from person to person depending on the specifics of the condition, the location of the hemorrhage, and the surrounding tissue involved. Therefore, assessments should be made based on specific clinical signs at the time. Particularly with hemorrhages in the medulla oblongata, once coma ensues, it's often impossible to fully awaken the patient, and many succumb to complications later on. Therefore, adequate psychological preparation is essential in clinical settings.

How does a brainstem hemorrhage clot get absorbed?

For patients with brainstem hemorrhage, edema generally enters the edema phase within 24 to 48 hours, and then gradually transitions into the absorption phase. During this period, it is first necessary to provide the patient with medications that enhance brain function, promote blood circulation and remove blood stasis, and nourish the nerves for treatment. At the same time, it is important to monitor changes in the patient's condition, and regularly perform a head CT scan to dynamically observe the changes in cerebral hematoma. In most cases, it is necessary to prevent various complications or concurrent diseases. If there is an abnormality in coagulation function, it is advisable to administer hemostatic drugs for treatment during the acute phase. However, once the patient's condition stabilizes, use medications that improve cerebral microcirculation and promote blood circulation and remove blood stasis for treatment.

The critical period for brainstem hemorrhage is several days.

For patients with brainstem hemorrhage, the first week after the onset is a critical period. During this time, the bleeding may gradually increase, and secondary cerebral edema may occur, leading to dysfunction of the brainstem and even respiratory and circulatory failure, which can endanger the patient's life. Therefore, for these patients, it is crucial to closely monitor any changes in their condition, transfer them to the intensive care unit, and closely monitor their vital signs. Special attention should be paid to the patient's blood pressure, respiration, heart rate, pupil reactions, consciousness, and limb activity. Dynamic follow-up head CT scans should be performed to observe any changes in the condition.

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.

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

Brainstem hemorrhage is dangerous if accompanied by high fever. Brainstem hemorrhage itself is a severe disease, and patients often experience disturbances of consciousness, coma, and paralysis of limbs. The hemorrhage can damage the center that regulates body temperature, leading to central fever. After falling into a coma, patients may encounter problems with expectoration and swallowing, which can easily lead to aspiration pneumonia and hypostatic pneumonia. Infections can also cause high fever. Patients need to use diuretics to reduce intracranial pressure, but excessive dehydration can also lead to dehydration fever. High fever exacerbates the consumption of the patient's body, increasing the physical burden and potentially leading to multiple organ failure. It is necessary to control the fever as soon as possible, using both physical cooling methods and medication.
