aspiration pneumonia


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

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.

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%.

aspiration pneumonia

Aspiration pneumonitis Pulmonology A condition characterized by the inhalation or inappropriate passage of highly acidic gastric content–food, gastric acid, vomitus-into the respiratory tract, a clinical event most common in the comatose; after the insult, there is progressive respiratory depression, hypoxia, tachypnea, and tachycardia; the tracheobronchial tree 'sweats' thin frothy fluid; lung parenchyma is acutely inflamed, hemorrhagic and edematous with atelectasis and necrosis Mortality Up to 70%.

Patient discussion about aspiration pneumonia

Q. What Causes Aspiration Pneumonia? My father is hospitalized with aspiration pneumonia. What causes this?

A. Aspiration pneumonia is a pneumonia that develops due to the entrance of foreign material that enter the bronchial tree (air tubes), usually oral or gastric contents (including food, saliva, or nasal secretions). Aspiration pneumonia represents a either a bacterial infection or a chemical inflammatory process due to inadequate swallowing mechanism.
