Pulmonary infection after cerebral hemorrhage surgery is more common clinically. The treatment is as follows: 1. actively treat the primary disease and keep the patient in a relatively stable state; 2. strengthen sputum drainage, regularly turn, pat the back, aspirate, give nebulization to promote sputum discharge, and if necessary, perform deep bronchoscopic aspiration to reduce the possibility of further aggravation of pulmonary infection. If the patient’s cough reflex is poor at this time and the secretions in the lungs cannot be coughed out on their own, tracheotomy is needed to promote sputum drainage. 3. Give empirical anti-infection treatment first, while performing sputum culture examination, and once the sputum culture results are returned, adjust the use of antibiotics according to the drug sensitivity results. At the same time, strengthen the patient’s nutritional support to improve immunity; 4. Dynamic monitoring of blood routine, calcitoninogen, lung CT and other examinations are needed during the treatment process to assess the patient’s treatment effect.
