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).

Another risk: If food and water haven't been withheld beforehand, the patient can vomit and inhale them into the lungs, and develop aspiration pneumonitis.
Another risk: If food hasn't been withheld beforehand, the possibility of the patient's vomiting, then inhaling it into the lungs and developing aspiration pneumonitis can occur.
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.
