Flexible Intubation Scope With or Without Video Laryngoscope in Supporting Endotracheal Tube Placement in Patients With Head and Neck Cancer Before Surgery

Completed · Not applicable

Conditions studied: Head and Neck Neoplasm

In brief

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).
