Logic Description: First event of Perioperative aspiration
Recommended study application: exposure, outcome.
Assertion statement: This cohort definition was executed on at least one real person-level observational health data source but did not result in a cohort with at least 1 person, as our OMOP used a custom standard concept for postoperative aspiration.

- Target Clinical Description
Perioperative aspiration refers to the accidental inhalation of gastric contents, oropharyngeal secretions, or foreign material into the tracheobronchial tree during surgical procedures. This event is a severe and potentially life-threatening complication that can lead to aspiration pneumonia, acute respiratory distress syndrome (ARDS), or even death if not promptly managed.
- Presentation of Perioperative Aspiration
Common presentations for perioperative aspiration include:
-
Sudden onset of coughing or choking during the surgical procedure -
Wheezing or stridor -
Decreased oxygen saturation levels -
New or increasing infiltrates seen on chest imaging -
Elevated respiratory rate and increased work of breathing
Assessment for Perioperative Aspiration
-
Immediate assessment of airway, breathing, and circulation -
Arterial blood gas analysis for evaluation of oxygenation and ventilation -
Chest X-ray or CT scan to assess for evidence of aspiration, such as infiltrates or consolidation -
Continuous monitoring of vital signs and oxygen saturation levels
Differential Diagnosis of Perioperative Aspiration
-
Anaphylaxis -
Pneumothorax -
Cardiac arrhythmia or ischemia -
Drug reaction or overdose -
Acute pulmonary embolism
Treatment Plan for Perioperative Aspiration
Initial management aims at securing the airway and restoring adequate ventilation and oxygenation. Suctioning of the trachea, bronchoscopy for foreign body removal, or endotracheal intubation may be required. Antibiotic therapy should be considered for aspiration pneumonia. Supportive care such as supplemental oxygen, mechanical ventilation, or fluid resuscitation might also be needed.
Prognosis for Perioperative Aspiration
The prognosis is highly variable and depends on the promptness of diagnosis and intervention. Early recognition and appropriate treatment can lead to more favorable outcomes. However, delays in management or severe aspiration events can result in significant morbidity and mortality, including ARDS, sepsis, or multi-organ failure. The patient’s pre-existing health conditions and the severity of the aspiration event are also important factors that influence the prognosis.
