Treatment and study plan

Primary outcomes

  1. First-pass success rate of videolaryngoscopic intubation without stylet

    Time frame: From the start of endotracheal intubation to 120 seconds

    An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords

Secondary outcomes

  1. Success rate of videolaryngoscopic intubation without stylet using BURP maneuver after failure of the first attempt

    Time frame: From the start of endotracheal intubation to 120 seconds

    An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords

  2. Incidence of using a stylet for the success of videolaryngoscopic intubation after the failure of the second attempt using the BURP maneuver

    Time frame: From the start of endotracheal intubation to 120 seconds

    An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords

  3. Incidence of successful endotracheal intubation after the failure of the third attempt using stylet

    Time frame: From the start of endotracheal intubation to 120 seconds

    An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords

  4. Time to completion of endotracheal intubation

    Time frame: From the start of endotracheal intubation to 120 seconds

    An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords
