1, lung infection Brain lesions may lead to pulmonary and respiratory vascular dysfunction, pulmonary edema bruising; longer periods of non-turning can lead to the accumulation of pulmonary secretions; and vomit accidentally inhaled into the trachea, etc., can contribute to the occurrence of pneumonia. Care should be strengthened, such as gently changing the patient’s position and patting the back every 3-4 hours, so that lung secretions do not accumulate for a long time and are easily discharged. Special care should be taken when feeding to prevent pneumonia as much as possible. Decubitus ulcers are prone to occur because of the restricted movement of the paralyzed limbs, easy pressure on the elevated parts of the bones, and local skin circulation and nutritional disorders, with the most common sites being the lower back, sacrococcygeal region, greater trochanter of the femur, external ankle, and heel. To avoid bed sores, patients can be helped to change their position every 2 hours; air rings and sponge cushions can be placed on the parts prone to bed sores. To keep the skin dry; local massage can also be performed to improve blood circulation. 3, acute gastrointestinal bleeding Most of the bleeding occurs within 1 week after the onset of the disease, more than half of the bleeding comes from the stomach, followed by the esophagus, manifested as vomiting blood or black stool. 4.Cerebral heart syndrome Within 1 week after the onset of the disease, the electrocardiogram can reveal ischemic stroke changes in the heart, arrhythmia, and even myocardial infarction may occur. 5. Central respiratory distress Most often seen in comatose patients. The respiration is fast, shallow, weak and irregular, or sigh-like breathing, apnea, which is due to the influence of the brainstem respiratory center, indicating the seriousness of the disease. 6, central erratic See in the acute and chronic phase of stroke. It is also a sign of serious illness. 7. Rectal dysfunction Patients with mild cerebral hemorrhage often have temporary “postural urinary retention” and dry stools because they are not used to defecating in the prone position. In severe cases, when the lesion affects the hemispheric motor center, frequent urination and increased bladder pressure often occur. If the third ventricle is stimulated, increased rectal motility often occurs, leading to a high degree of defecation hyperactivity, with patients having frequent bowel movements but smaller volumes per bowel movement. If the gray nodes are damaged, involuntary bowel movements may occur. If the whole brain is damaged, patients in deep coma often have diarrheal incontinence or urinary retention. 8. Electrolyte disorders Patients with cerebral hemorrhage cannot respond to subjective sensations due to coma or aphasia, which is coupled with complex symptoms and more treatment conflicts; they also often suffer from frequent vomiting, fever, sweating, application of dehydrating agents and insufficient rehydration resulting in water loss, electrolyte disorders and renal failure. Sometimes acidosis is caused by hypoxia, starvation, abnormal respiration, etc., or occasional alkalosis occurs. However, the above-mentioned diseases are often overlooked in the case of coma or co-infection, which makes the disease aggravate day by day, so it should be observed. When it is found that the respiration deepens and accelerates, tachycardia, consciousness disorder aggravates, blood pressure drops, urine volume decreases or no urine, limbs and face edema or dehydration, etc., we should look for the cause carefully and make timely examination of carbon dioxide binding capacity, non-protein nitrogen, blood gas analysis and quantitative electrolyte measurement, etc., and deal with the abnormalities promptly when found. When cerebral hemorrhage affects the subthalamic and anterior parts of the brain, the heat dissipation mechanism is destroyed, which can cause persistent hyperthermia, with body temperature often reaching 40℃ or more, and can be accompanied by no sweating, cold limbs, tachycardia, increased respiration and other symptoms. However, white blood cells are generally not increased, and compound aminopyrine and aspirin can not make it fall. Sometimes cooling with barbiturate plus ice pillow is effective, and if not treated in time, death can occur in a few hours.
