Pneumonia, Aspiration

Aspiration pneumonia occurs when food, liquid, saliva, or vomit is inhaled into the lungs, introducing bacteria that lead to infection. It is more common in people with impaired swallowing, altered consciousness, or conditions like stroke, dementia, or alcohol intoxication. Symptoms often include cough, fever, shortness of breath, chest pain, and sometimes foul-smelling sputum. Chest X-ray findings usually show infiltrates in dependent lung areas, such as the right lower lobe. Treatment requires antibiotics with anaerobic coverage, alongside supportive care and addressing the underlying risk factors to prevent recurrence.

# Aspiration Pneumonia Treatment Summary Aspiration pneumonia is treated primarily with broad-spectrum antibiotics targeting gram-positive, gram-negative, and anaerobic organisms. Ampicillin-sulbactam is recommended as a first-line IV option with potential for oral step-down therapy. Piperacillin-tazobactam and meropenem are preferred for hospitalized or critically ill patients, especially when complications like abscess or empyema are suspected; meropenem offers a safety advantage with lower seizure risk. Levofloxacin serves as an alternative for penicillin-allergic patients and when aspiration versus community-acquired pneumonia distinction is unclear.
