The brainstem is composed of the medulla oblongata, pons and midbrain from the bottom up. If a patient has a brainstem hemorrhage, he should immediately seek medical attention and have a cranial CT examination to clarify the cause and then undergo timely treatment. The consequences of brainstem hemorrhage are different due to different parts of the brainstem. 1. medulla oblongata hemorrhage: If it is a light hemorrhage, there may be vertigo, choking and coughing, and sensory impairment on one side of the face and the opposite side of the body. In case of heavy hemorrhage, there may be impaired consciousness, decreased blood pressure, arrhythmia, etc., followed by death. 2. cerebral bridge hemorrhage: If the amount of hemorrhage is small, consciousness is clear, but there are headache, vomiting, vertigo, and weakness of the limbs on the contralateral side of the lesion. If there is a large amount of bleeding, there may be coma, pinpoint pupils, coffee-like vomit, tetraplegia, and there may be symptoms of stiff limbs, head tilted back, and body tilted like an arch, and the patient may die within a few hours; 3. Midbrain hemorrhage: if it is a light hemorrhage, there may be headache, vomiting, drooping eyelids, dilated pupils, unsteady walking, accompanied by slurred speech and difficulty in swallowing. Severe forms may have consequences such as drowsiness, coma, and tetraplegia, and may be at risk of rapid death. If brainstem hemorrhage is suspected, the patient should be placed flat on the ground, avoid moving, and the head should not be shaken violently. Make sure the airway is open, tilt the head to the side to prevent accidental aspiration of vomit, clean foreign bodies from the nose and mouth, unbutton the patient’s collar, tie and trouser belt, and remove dentures, if any, to avoid asphyxiation. At the same time, call the emergency center or hospital for help as soon as possible, follow the doctor’s instructions and wait to be taken to the hospital for treatment.
