Brainstem hemorrhage is a type of cerebral hemorrhage, occurring within the brainstem, which is the central hub of human life. Thus, once a brainstem hemorrhage occurs, the condition becomes extremely complicated and severe, with very high mortality and disability rates. Clinically, brainstem hemorrhages of less than three milliliters have a mortality rate close to 70%. Those exceeding five milliliters have a mortality rate close to 90%, and hemorrhages over ten milliliters are invariably fatal. In recent years, there has been an increasing trend in brainstem hemorrhages, affecting younger populations. This is mainly due to high work stress, uncontrolled diet, lack of exercise, and notably, a lack of awareness and attention to hypertension among young people, which ultimately leads to brainstem hemorrhage. Brainstem hemorrhage is a very dangerous disease.

Can you survive with 10 milliliters of bleeding in the brainstem?

A brainstem hemorrhage of 10 milliliters is relatively significant; whether the patient can survive depends on specific circumstances. First, it must be determined if the hemorrhage has compressed important neural nuclei, causing apparent respiratory and circulatory dysfunction. If such dysfunction occurs, it could severely threaten the patient's life. Additionally, the patient's level of consciousness and the availability of timely and effective treatment, along with necessary life support, must be considered. For example, if respiratory and circulatory dysfunction arises, it might be appropriate to use vasopressors to maintain blood pressure and ventilators to assist breathing. If effective life support is available, it is often possible to survive the peak period of swelling and preserve life.

Is vomiting severe in brainstem hemorrhage?

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 brainstem hemorrhage painful?

Brainstem hemorrhage is relatively painful, and most patients with brainstem hemorrhage will exhibit severe headaches and dizziness. The nature of the pain is intense, resembling a cutting pain that is hard to tolerate. However, when the amount of bleeding is large, it can quickly cause damage to important nerve nuclei in the brainstem, and even affect the central nervous system responsible for consciousness, leading to the patient falling into a stupor or coma. In such cases, the patient may not feel pain, but for those who are conscious, severe headaches and dizziness, accompanied by a strong sense of vertigo, especially noticeable when changing positions, often occur.

Pre-symptoms of brainstem hemorrhage

Brainstem hemorrhage is extremely dangerous, and once a massive hemorrhage occurs, the patient can quickly lose consciousness and generally there are no effective emergency measures available. The patient will quickly die due to the involvement of the centers controlling heartbeat and breathing. The early symptoms of brainstem hemorrhage are not particularly obvious, but a careful medical history may reveal that patients often experience excessive fatigue, stress, emotional agitation, and poor sleep before the hemorrhage. Patients may show early signs such as dizziness, blurred vision, double vision, limb weakness, and slurred speech. If a patient has very high blood pressure and exhibits these early symptoms, especially if there is discomfort in the neck and upper back area, it is crucial to be highly vigilant and seek immediate medical attention. The prognosis for brainstem hemorrhage is very poor, thus it is essential to focus on preventive measures and properly control blood pressure.

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.
