  • Title: Rescue ventilation: resolving a "cannot mask ventilate, cannot intubate" situation during exchange of a Combitube for a definitive airway.
    Author: Rich JM, Mason AM, Tillmann HA, Foreman M.
    Journal: AANA J; 2009 Oct; 77(5):339-42. PubMed ID: 19911642.
    Abstract:
    Our anesthesia care team was called to care for a patient who was admitted to the emergency department with the esophageal-tracheal double-lumen airway device (Combitube, Tyco Healthcare, Nellcor, Pleasanton, California) in place, which needed to be exchanged for a definitive airway because the patient required an extended period of mechanical ventilation. Several techniques were attempted to exchange the esophageal-tracheal Combitube (ETC) without success. First, we attempted direct laryngoscopy with the ETC in place after deflation of the No. 1 proximal cuff and sweeping the ETC to the left. We were prepared to use bougie-assisted intubation but could not identify any airway anatomy. After removal of the ETC, we unsuccessfully attempted ventilation/intubation with a laryngeal mask airway (LMA Fastrach, LMA North America, San Diego, California). Our third attempt was insertion of another laryngeal mask airway (LMA Unique, LMA North America) with marginal ventilation, but we again experienced unsuccessful intubation using a fiberscope. The ETC was reinserted after each intubation attempt because mask ventilation was impossible. Before proceeding with cricothyrotomy, we repeated direct laryngoscopy but without the ETC in place. We identified the tip of the epiglottis, which allowed for bougie-assisted intubation. This obviated the need for emergency cricothyrotomy.
