Pulmonary infection is one of the complications of cerebral hemorrhage. The risk factors of pulmonary infection in patients include: (1) the severity of the disease and the decline of the body's preventive function after illness; (2) Most of the patients are middle-aged and elderly people, and their disease resistance is weak, which is prone to cross-infection in hospital; (3) Patients have different degrees of dysphagia, which is easy to cause aspiration; (4) disturbance of consciousness, slow cough reflex, and insufficient discharge of oropharyngeal and tracheal secretions; (5) Stay in bed for a long time due to illness, which leads to the decrease of respiratory and pulmonary secretions; (6) There are relatively many invasive operations, such as oxygen inhalation through nasal catheter, gastric tube insertion and tracheal intubation, which increase the chances of bacteria being brought into the body. Prevention should pay attention to provide a safe and comfortable environment, put the patient in a quiet, clean and comfortable ward, regularly open the window for ventilation and wet cleaning, and keep the indoor air fresh, with a temperature of 18℃ ~ 20℃ and a relative humidity of 55% ~ 60%. Disinfect indoor air with ultraviolet rays once a day. Pay attention to prevent patients from catching cold, because cold can make patients' airway blood vessels contract, the resistance of mucosal epithelium to ischemia and hypoxia decreases, and bacteria are easy to invade. Keep your mouth clean, remove oral secretions, food residues and vomit in time, and it is advisable to digest a small amount of food and semi-liquid to empty your stomach in time. Nasal feeding for people with dysphagia. In order to prevent the reflux of nasal feeding, turn over before nasal feeding and fully suck sputum. The speed of nasal feeding should not be too fast, nor too much at a time. Try not to turn over and suck sputum for a short time after nasal feeding to avoid vomiting. The absence of pulmonary infection is not the key to acute cerebral hemorrhage. The key depends on whether there is further bleeding, whether the brain edema is further aggravated, whether cerebral hernia will form, and whether bleeding will inhibit the respiratory center. First, adhere to reliable drug treatment, mainly to dilate blood vessels, nourish nerves and improve cerebral microcirculation. Then take comprehensive measures such as acupuncture, massage, traditional Chinese medicine and functional exercise to speed up and improve the degree of recovery. We use Guilongnaokang to repair damaged brain cells, which is rich in neurotrophic factors, small molecular peptides and various amino acids. These effective components can directly act on brain cells, promote the synthesis of protein, resist cerebral cortex hypoxia, improve brain energy metabolism, accelerate cerebral blood circulation, and facilitate the recovery of diseases.
