Study Overview

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.

Inclusion Criteria

  • •American Society of Anesthesiologists (ASA) physical status I-III
  • •Body Mass Index (BMI) of 30-40
  • •Scheduled for an elective surgery that requires tracheal intubation

Exclusion Criteria

  • •Patients with abnormalities of the upper airway that require awake tracheal intubation
  • •Chronic obstructive pulmonary disease
  • •Congestive heart failure
  • •Pregnant patients

Outcomes

Primary Outcomes

Tolerable Apnea Time (TAT)

Time Frame: 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 Outcomes

  • 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)
