Evaluation of Apnea Tolerance in Bariatric Patients Following Rapid-sequence Induction of Anesthesia

Evaluation of Apnea Tolerance in Bariatric Patients Following Rapid-sequence Induction of Anesthesia

The purpose of this study is to compare the effect of the 25° head-up position versus the 55° head-up position on tolerable apneic time (TAT) in bariatric patients scheduled for laparoscopic adjustable gastric band surgery following maximum preoxygenation and rapid-sequence induction (RSI) of anesthesia.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) physical status II-III patients
• Body Mass Index (BMI) of 40-60
• Scheduled for an elective laparoscopic adjustable gastric band surgery

Exclusion Criteria:

• Patients with abnormalities of the upper airway that require awake tracheal intubation
• Asthma
• Chronic obstructive pulmonary disease
