Emergency physician-performed emergency bronchoscopy in cardiac arrest patient due to acute foreign body airway obstruction

As foreign body airway obstruction (FBAO) can be life-threatening, it has to be promptly diagnosed and treated. We report a case series of three patients presenting to the emergency department with cardiac arrest due to FBAO. In each case, ventilation was difficult due to high airway resistance. As FBAO was suspected, the emergency physician did a prompt flexible bronchoscopy to confirm the diagnosis and retrieve the foreign body. Flexible bronchoscopy is an important diagnostic and therapeutic tool for emergency airway management, and is a relatively safe procedure if performed by a trained personnel. The life-saving benefits of bronchoscopy outweigh the small risks of complications such as bleeding, desaturation and pneumothorax. In the three cases, the removal of the obstructing material led to immediate improvements in oxygenation and ventilation. The patients had return of spontaneous circulation after cardiopulmonary resuscitation and definite airway control.
