Aspiration pneumonia is often caused by inhalation of harmful gases or molecular particles, and can also be caused by local chemical irritation of the lungs due to food reflux. The preferred medication for this patient is still antibiotics, which can be given empirically as cephalosporins, penicillins, quinolones, etc. Sensitive antibiotics can also be selected based on the patient’s pathogen culture and drug sensitivity test results. At the same time, the airway secretions should be cleared to keep the airway open, and symptomatic treatment should be given to the patient’s clinical symptoms, such as aminoglutethimide, bromhexine, and acute syrup to stop cough and expectoration.
