Trial Outcomes & Findings for Bougie Use in Emergency Airway Management (NCT NCT02902146)

Race and Ethnicity were not collected from any participant.

First pass success is defined as placement of the endotracheal tube (ETT) into the trachea on the first attempt. An attempt begins when the laryngoscope enters the mouth, and ends if either of the following occur: 1. the laryngoscope leaves the mouth, regardless of whether an attempt was made to pass the endotracheal tube or bougie. 2. if the operator cannot intubate the trachea with the first tube device (ETT or bougie), and switches to any other tube device, even if the laryngoscope blade remains in the mouth. A patient will be considered to achieve the primary outcome if they are intubated successfully on the first attempt.

First pass success without hypoxemia. Hypoxemia is defined as a pulse oximetry value (SpO2) less than 90% at any point during intubation, or a drop of more than 10% from baseline if starting below 90%. The outcome of hypoxemia will be recorded beginning when the first attempt begins and ending one minute after inflation of the ETT cuff. A patient will be considered to achieve this outcome if 1) they are intubated successfully on the first attempt, and 2) do not experience hypoxemia on the first attempt.

Time to intubation will be defined as the time elapsed between the beginning of the intubation attempt to inflation of the ETT cuff when the tube is in the trachea.

defined as passage of the ETT into the esophagus, with subsequent ventilation, and then removal. Clinically, esophageal intubation is identified by the absence of end-tidal carbon dioxide, abnormal physical exam, and hypoxia. This does not count passage of the ETT into the esophagus during the attempt if the ETT is removed during the attempt.

Hypoxemia is defined as a pulse oximetry value (SpO2) less than 90% at any point during intubation, or a drop of more than 10% from baseline if starting below 90%. The outcome of hypoxemia will be recorded beginning when the first attempt begins and ending one minute after inflation of the ETT cuff.
