aspiration pneumonia

as·pi·ra·tion pneu·mo·ni·a

bronchopneumonia resulting from the inhalation of foreign material, usually food particles or vomit, into the bronchi; pneumonia developing secondary to the presence in the airways of fluid, blood, saliva, or gastric contents. Synonym(s): deglutition pneumonia

aspiration pneumonia

An infectious process characterised by inhalation of colonised oropharyngeal material into the respiratory tract, which most commonly occurs in patients with impaired sensorium.
Aetiology
• Hospital acquired—Staphylococcus aureus, Enterobacteriaceae, Pseudomonas, mixed oropharyngeal flora.
• Community acquired—Streptococcus pneumoniae, H influenzae, mixed oropharyngeal flora.
Clinical findings
Progressive respiratory depression, hypoxia, tachypnoea and tachycardia; the tracheobronchial tree “sweats” a thin frothy fluid.
Risk factors
Poor oral hygiene, clouded sensorium (drugs, alcohol, anaesthesia, coma, CVA, seizures), impaired gag reflex (intubation, myopathy, neurologic disorders, tracheostomy, vocal cord paralysis), oesophageal dysfunction (achalasia, strictures, tumours), others (elderly, feeding tube, delayed gastric emptying, critical illness).
Mortality
Up to 70%.
