  • Title: [An almost fatal airway obstruction caused by a secretion plug in an endotracheal tube].
    Author: Andersen EB, Olsen KS.
    Journal: Ugeskr Laeger; 2014 Dec 15; 176(25A):. PubMed ID: 25497629.
    Abstract:
    Airway obstruction caused by a secretion plug in an endotracheal tube or a tracheostomy cannula can be a serious complication to mechanical ventilation. This case describes an event caused by a mucus plug localized to the distal part of a tracheostomy tube in a tetraplegic patient. The plug functioned as a check valve, allowing air to pass in - but not out - of the patient. A suction catheter could be passed through the airway without any resistance, and thus the airway was believed to be free. The event, which had an almost fatal outcome due to hyperinflation of the lungs, was relieved by replacement of the tracheostomy cannula.
