This prospective observational cohort study was designed to assess the relationship between ETT cuff pressures and airway pressures in obese patients undergoing laparoscopic bariatric surgery. We hypothesized that the ETT cuff pressures will rise in direct relationship to increases in the peak and mean airway pressures.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) risk indicators I-III manage to undergo Laparoscopic bariatric surgery between the ages of 18-70

Exclusion Criteria:

• Patients with drug allergies, chronic pain, long-term opioid use, history of psychiatric illness, and need for emergency surgery were excluded from the study.
