Not Applicable
Completed
- Conditions
- General Surgery
- Registration Number
- NCT03056820
- Lead Sponsor
- University of Kansas Medical Center
- Brief Summary
The purpose of this study is to compare the effect of the 25° head-up position versus the 55° head-up position on tolerable apnea time (TAT) after induction of general anesthesia in patients with a body mass index (BMI) of 30-40.

- Primary Outcome Measures
Name Time Method Tolerable Apnea Time (TAT) Time between start of induction of general anesthesia (SpO2 100%) to decline of SpO2 94%, up to eight minutes Measure of the TAT between groups to determine if the TAT is a function of the participant's position.
- Secondary Outcome Measures
Name Time Method Length of time to intubation (TTI) Time between start of the tracheal intubation procedure to completion of tracheal intubation, up to 2 minutes Peripheral arterial hemoglobin oxygen saturation (SpO2) trough Time until SpO2 decreased to 92%, up to 8 minutes Measure of the rebound SpO2. It is the lowest SpO2 reading reached subsequent to start of mechanical ventilation at the SpO2 value of 94% and it represents final completion of SpO2 decline.
