NCT03757091

Brief Summary

This trial studies how well flexible intubation scope with or without video laryngoscope works in supporting endotracheal tube placement in patients with head and neck cancer before surgery. Flexible intubation scope and video laryngoscope are devices that have a small camera to help the doctor see the patient's airway on a screen. Both devices may help the doctor who gives anesthesia prevent complications from placing the breathing tube (such as pain or mouth injury).

Outcome Measures

Primary Outcomes (1)

  • Difficult Endotracheal Tube (ETT) Placement

    Defined as the number of participants with any of the following during initial intubation attempt.1 Intubation time exceeding 60 seconds, 2. Failure to intubate on the first attempt, 3. Provider assessment of intubation as difficult or unsuccessful.

    intubation time, up to 3 minutes

Secondary Outcomes (4)

  • Intubation Time

    time captured when FIS passed the lips to CO2 confirmation

  • Number of Intubation Attempts

    intubation time, up to 3 minutes

  • Rate of Failure at Intubation

    during intubation process/attempt

  • Ease of Intubation (Provider Assessment)

    duration of intubation attempt

Study Arms (2)

Arm A (flexible intubation scope)

ACTIVE COMPARATOR

Patients undergo flexible scope intubation up to 2 attempts following induction of general anesthesia and adequate manual ventilation. In case of failed 2 attempts, patients undergo a third attempt utilizing another technique or device.

Procedure: Tracheal Intubation

Arm B (flexible intubation scope,video laryngoscope)

EXPERIMENTAL

Patients undergo flexible scope intubation and video laryngoscopy up to 2 attempts following induction of general anesthesia and adequate manual ventilation. In case of failed 2 attempts, patients undergo a third attempt utilizing another technique or device.

Device: LaryngoscopyProcedure: Tracheal Intubation

Interventions
