J69.0-1/J69.8
DESCRIPTION
Following aspiration, a patient may develop pneumonitis or pneumonia. Aspiration pneumonitis develops within hours of the aspiration event and is more common in previously healthy people who aspirate gastric acid. Antibiotics will not benefit these patients unless there is infection present.
Pneumonia following aspiration of gastric contents and/or commensal organisms from the oropharynx usually occurs in debilitated patients and presents with symptoms and signs of community-acquired pneumonia, but may have a more indolent onset and is more frequently complicated by lung abscess or empyema.
There may be solid (food) particles or other foreign bodies aspirated. The organisms involved are polymicrobial, i.e. Gram-positive and anaerobes. Aspiration pneumonia should be suspected in patients with episodic or prolonged decreased level of consciousness, e.g. in alcoholics, drug overdoses, epileptics, strokes, or those with swallowing problems.
MEDICINE TREATMENT
Antimicrobial therapy
Continue therapy until there are no features of sepsis.
- Amoxicillin/clavulanic acid, IV, 1.2 g 8 hourly, until patient is apyrexial and stable for 24 hours.

- Amoxicillin/clavulanic acid, oral, 875/125 mg 12 hourly.
Severe penicillin allergy: (Z88.0)
- Moxifloxacin, IV, 400 mg daily, until patient is apyrexial for 24 hours.
Follow with:
- Moxifloxacin, oral, 400 mg daily.
If nosocomial infection present (developed >48 hours post admission), see Hospital-acquired pneumonia.
REFERRAL
- Hypoxaemia non-responsive to facemask oxygen.
