Pneumonia caused by vomiting generally refers to aspiration pneumonia caused by inhalation of vomitus into the airway, and the treatment is as follows: 1, coughing, knocking back expectoration: if the vomitus enters into the airway less, you can generally cough, knocking back expectoration, so that inhalation can be discharged. 2, anti-infective treatment, alveolar lavage: if the cough does not get better over a long period of time, and the inhalation is large, you need to carry out a CT examination of the lungs to clarify the severity of the infection. If the cough does not improve for a long time and the amount of inhalation is large, CT examination of the lungs is needed to clarify the severity of infection. If the infection is combined with bacterial infection, it is necessary to apply antibiotics to anti-infection treatment, and at the same time give drugs to relieve cough and resolve phlegm. If the lung CT is clear that the amount of inhalation is large and the inhaled foreign body can be seen, if necessary, bronchoscopy should be done, and the inhaled foreign body should be discharged through alveolar lavage, and anti-infective treatment should be carried out at the same time.
