Use of extracorporeal membrane oxygenation for bronchoscopic removal of a tracheal foreign body in a child.

BACKGROUND

Bronchoscopic removal of a foreign body is a common emergency procedure in paediatric otolaryngology. It is potentially life-threatening, as complete airway obstruction caused by the foreign body can lead to hypoxic cardiac arrest during the manipulation of the object.

CASE REPORT: This paper presents a child who had aspirated a foreign body that could not be extracted conventionally via rigid bronchoscopy in the first instance. Subsequently, it was extracted at repeat bronchoscopy under controlled respiratory conditions maintained by an extracorporeal gas exchange circuit - extracorporeal membrane oxygenation, using a polypropylene hollow fibre oxygenator commonly employed in cardiac surgery (rather than a more expensive polymethyl pentene oxygenator commonly used in extracorporeal membrane oxygenation).

CONCLUSION

Extracorporeal membrane oxygenation use can be considered in exceptional cases of upper airway emergencies, even in resource-poor settings, and can avoid more hazardous thoracotomy and bronchotomy procedures.
