Postoperative cerebral hemorrhage patients are very susceptible to complications of lung infection, the main reasons are as follows: 1, the patient after cerebral hemorrhage bedridden for a long time, due to the effect of gravity, the secretion in the trachea is easy to deposit in the lower part of the lungs, and it is not easy to cluck out and fall pneumonitis occurs. 2, cerebral hemorrhage patients can have impaired or loss of swallowing function, and it is easy to suck in the colonized bacteria in the mouth into the lungs accidentally and then inhalation pneumonitis occurs. Aspiration pneumonia. Because of the two factors of aspiration and aspiration, lung infection is easy to occur after cerebral hemorrhage surgery, and the bacteria of lung infection are mostly anaerobic bacteria and gram-negative bacilli in the hospital. At the same time, patients after cerebral hemorrhage have no ability to expel sputum on their own, sputum can not be eliminated by themselves, so the anti-infection time is relatively long, if the patient has a lot of sputum and it is not easy to sputum, you can use bronchoscopic sputum suction.
