  Aspiration Pneumonia - Health EncyclopediaNews Story - KNBC | Los Angeles
Aspiration pneumonia is inflammation of the lungs and bronchial tubes due to breathing in a foreign material.
Aspiration pneumonia is caused by inhaling foreign material (usually food, liquids, vomit, or secretions from the mouth) into the lungs.
Aspiration of foreign material (often the stomach contents) into the lung can occur with disorders that affect normal swallowing or disorders of the esophagus (esophageal stricture, gastroesophageal reflux).

  Pneumonia - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-09-19)
Pneumonia is a medical condition that describes a result of a variety of diseases in which the small, air-filled sacs in the lung responsible for absorbing oxygen from the atmosphere are flooded with fluid.
The symptoms of infectious pneumonia are the result of both the invasion of the lungs by microorganisms and the immune system's response to the infection.
In cases of viral pneumonia caused by influenza A or B, patients who are seen within 48 hours of the onset of symptoms may be treated with oseltamivir or zanamivir.

 Aspiration pneumonia - Wikipedia, the free encyclopedia
Aspiration pneumonia is a specific form of lung infection (pneumonia) that develops when oral or gastric contents (including food, saliva, or nasal secretions) enter the bronchial tree.
Aspiration pneumonia is often caused by an incompetent swallowing mechanism, such as occurs in some forms of neurological disease (a common cause being strokes) or while a person is intoxicated.
Whether aspiration pneumonia represents a true bacterial infection or a chemical inflammatory process remains the subject of significant controversy.

 Prevention of Aspiration Pneumonia: A Research-Based Protocol
Aspiration is the introduction of a foreign substance into the lungs, but the mere instillation of foreign substance into the subglottic airway is not sufficient to produce disease.
Aspiration pneumonia is diagnosed clinically by noting its manifestations: a predisposition for aspiration; recovery of oropharyngeal, gastric or exogenous secretions from the pulmonary bed; and radiographic evidence of an infiltrative process, usually in a gravity-dependent section of the lung.
Risk factors associated with aspiration pneumonia are not clearly defined; although certain patient characteristics, such as altered level of consciousness, depressed cough and gag reflexes, gastrointestinal disorders, use of various breathing and feeding tubes, and increased age are associated with increased risk for aspiration pneumonia.

Aspiration pneumonia is an inflammation of the lungs and bronchial tubes caused by inhaling foreign material (usually food, drink, vomit, or secretions from the mouth) into the lungs.
Aspiration of foreign material (often the stomach contents) into the lung can be a result of disorders that affect normal swallowing, disorders of the esophagus (esophageal stricture, gastroesophageal reflux), or decreased or absent gag reflex in unconscious or semi-conscious individuals.
The outcome depends on the severity of the pneumonia, the type of organism, the extent of lung involvement.

 Postgraduate Medicine: Aspiration pneumonia
Aspiration pneumonia most often occurs in the presence of impairment of protective upper and lower airway reflexes in patients who have a decreased level of consciousness or central nervous system disease.
Whether aspiration pneumonia develops after an episode of aspiration is determined by the volume of material aspirated, its character (eg, acidic versus neutral, liquid versus particulate, infected versus sterile), the frequency of aspiration episodes, and the adequacy of host defenses.
Patients with hospital-acquired aspiration pneumonia may be treated with cefepime hydrochloride (Maxipime) or ceftazidime plus clindamycin or metronidazole; a beta-lactam and beta-lactamase inhibitor combination such as ampicillin and sulbactam, piperacillin sodium and tazobactam sodium (Zosyn), or ticarcillin and clavulanate potassium (Timentin); or a newer fluoroquinolone.

 Aspiration Pneumonia: Current Concepts and Approach to Management
Aspiration of pathogens from a previously colonized oropharynx is the primary pathway by which organisms gain entrance to the lungs, and therefore, in a broad sense, most pneumonias, are aspiration-related.
While pneumonia is part of the infectious aspiration syndrome, other infectious syndromes can result, including lung abscess, necrotizing pneumonia, and empyema.

Because community-acquired aspiration pneumonia usually involves anaerobic bacteria, aspiration pneumonia should be viewed as part of a continuum that can progress to cavitation (lung abscess), or even empyema formation.

Antibiotic therapy for patients with aspiration pneumonia should be based on an assessment of severity of illness (severe or nonsevere infection; Table III), where the infection was acquired (community versus nosocomial), and the presence or absence of risk factors for gram-negative rod colonization.

 Australian Prescriber - Aspiration pneumonia and pneumonitis
Aspiration of oropharyngeal or gastric contents is a common, but often unrecognised cause of pneumonia.
However, the term aspiration pneumonia is reserved for pneumonia arising when the size of the inoculum is large and/or host defences fail.
Aspiration of gastric contents can still occur and aspiration pneumonia remains a common cause of morbidity and death in patients fed this way.

Pneumonia from aspiration is the result of ingestion of a very large load of bacteria into the lower respiratory system where the infestation overwhelms the weakened immune system protection.
First, for a patient to develop pneumonia from aspiration, he/she must be significantly ill-CVA, surgery, heart attack, etc. Any severe illness causes a stress response (via the hypothalamus) in the sick patient which lowers the body's immune system's ability to fight off bacteria.
Pneumonia does not occur by itself; it occurs as a result of the serious illness and usually 3 to 7 days after the medical event.

The risk of developing pneumonia rises when aspiration is frequent, the amount of material aspirated is large or acidic (such as stomach contents) or infected (as in periodontal/dental disease.) It is also more likely if solid material is aspirated.
Silent or recurrent aspiration may require more detective work including modified barium swallow study, videoflouroscopy (a swallowing study) and evaluation by a feeding specialist (usually an OT or SLP with special expertise in the area of feeding disorders) or team of specialists (such as at the SAFE feeding clinic).
