Second Generation LMA Versus Endotracheal Tube in Obese Patients
February 13, 2024 updated by: Tiffany B Moon, University of Texas Southwestern Medical Center
The Use of a Second-Generation Laryngeal Mask Airway Versus Endotracheal Tube in Obese Patients
This prospective, randomized, comparative study is intended to enroll a total of 148 patients with a BMI 30-49.9
kg/m2 undergoing surgery at Parkland Hospital.
The efficacy and performance of a second-generation LMA will be compared to endotracheal intubation.
A standardized anesthetic protocol that is usual and customary for the type of operation the patient is having will be provided to the anesthesia teams of enrolled subjects.
The remainder of the anesthetic care of the subject will not deviate from the standard of care.
