About this study
Official title: Comparison of GlideScope and Airway Scope for Intubating Morbidly Obese Patients: A Randomized Controlled Study
This study compares the time required to complete intubation in obese patients (Body Mass Index 40 or greater) when using either the GlideScope or Airway Scope video laryngoscope device to help place the endotracheal tube.
Read the detailed description
This is a randomized controlled trial of two video laryngoscope devices when used in patients with high (≥40) Body Mass Index (BMI): Airway Scope (Nihon Kohden) and GlideScope (Verathon Inc.). The study compares several outcomes as proxies for ease of intubation including time to complete intubation, number of attempts needed, minimum peripheral oxygen saturation (SpO2) during intubation, and number of episodes of SpO2 falling below 90% before intubation is completed. The patient population is consenting adult patients with BMI ≥40, who are already scheduled for general anesthesia. Intubations will be performed by attending anesthesiologists or anesthesiology residents. Obesity is a known risk factor for difficult intubation due to anatomical changes caused by increased soft tissue around the face and neck. Obese patients' blood oxygen level can rapidly fall during intubation because these patients often have reduced functional residual capacity, and the acuity of any complications may also be increased because these patients also often have additional comorbidities.

The count of attempts required to complete the intubation procedure, with completion defined as confirmed end-tidal CO2
Measured: Perioperative/Periprocedural
Minimum SpO2 observed during intubation
The minimum value of SpO2 observed during the intubation procedure
Measured: Perioperative/Periprocedural
