1. Pulmonary infection. Pulmonary infection is one of the main complications and one of the main causes of death in people with cerebral hemorrhage. Within 3-5 days after cerebral hemorrhage, comatose patients are often combined with pulmonary infection . 2. Upper gastrointestinal bleeding. It is one of the serious complications of cerebrovascular disease, i.e., stress ulcer, and cerebral hemorrhage combined with upper gastrointestinal hemorrhage is mostly of mixed type and medial capsule type, accounting for 49% and 36%, respectively. The mechanism of occurrence is due to lesions in the inferior optic thalamus and brainstem, and now it is thought to be related to the inferior anterior optic thalamus, posterior gray-white nodes and vagal nuclei within the medulla oblongata. The autonomic center is in the inferior optic thalamus, but its higher centers are in the frontal orbital surface, hippocampal gyrus and limbic system, and the mechanism of gastrointestinal hemorrhage is related to the primary or secondary lesions in the above mentioned areas. 3. Decubitus ulcers. It is mainly a series of manifestations of ischemia and necrosis caused by prolonged compression of local skin and tissues due to long-term non-change of body position. Patients with cerebrovascular disease, due to more elderly patients, limb paralysis, long-term bed-ridden, activity inconvenience, easy for the bone bulge and other parts of the pressure, so that local tissue ischemia and hypoxia. 4, common complications after brain hemorrhage surgery. Pulmonary infection rebleeding, gastrointestinal stress ulcers, renal failure and multiple organ failure (MOF), etc. 5. Depression and anxiety reactions after cerebrovascular disease. Post-cerebrovascular depression is a more common affective disorder in cerebrovascular disease and should be given great clinical attention. Compared with depression, post-cerebrovascular depression has more depressive mood in the morning and less in the night. The degree of depression is significantly more severe in those with cortical damage than in those with subcortical damage, and the degree of depression is significantly greater in those with anterior brain damage than in those with posterior damage. (1) Characteristic symptoms of depressive reactions: ① bad mood, pessimistic mood, bad self-perception. (2) Sleep disturbance, insomnia, excessive dreaming or early awakening. (3) Loss of appetite, not thinking about eating. ④Loss of interest and pleasure, lack of motivation and energy for anything. (5) Inability to take care of oneself, self-blame and self-condemnation, negative desire to die. (6) Rapid weight loss. (7) Low sexual desire or even no sexual desire. (2) Characteristic symptoms of anxiety reactions: ① Persistent tension and anxiety. (2) Concurrent psychological symptoms, such as poor concentration, memory loss, sensitivity to sound and easy irritation. (3) Simultaneous physical symptoms, including sympathetic arousal symptoms, such as increased blood pressure, rapid heartbeat
chest tightness, rapid inspiration, irritability. The symptoms of parasympathetic excitation, such as polyuria and diarrhea due to increased gastrointestinal activity, are also present.
