aspiration pneumonitis

aspiration pneumonitis

Acute lung injury after inhalation of gastric acidic gastric content (food, gastric acid, vomitus), which causes chemical burns of the tracheobronchial tree and pulmonary parenchyma. Tissue destruction facilitates colonisation by bacteria and subsequent infection; lung parenchyma is acutely inflamed, haemorrhagic and oedematous with atelectasis and necrosis.
 
Aetiology
Altered consciousness (e.g., drug overdose), seizures, CVA, anaesthetics.

Autopsy findings
Aspiration pneumonia is not a “good” cause of death on a death certificate for a patient who dies in ITU, as patients are usually NPO (oral foods and fluids withheld).

Aspiration of gastric contents into the respiratory tract reportedly causes significant morbidity and mortality and is accepted as the key initiating event for aspiration pneumonitis - a form of acute lung injury caused by the acidity of the gastric contents, and aspiration pneumonia - the consequence of the growth of pathogenic bacteria contained in the oropharynx aspirated into the tracheobronchial tree.

If gastric contents are aspirated into the lungs it may result in aspiration pneumonitis leading to extended ventilation and admission to intensive care (Farman 2004).
