Effects of Dexmedetomidine on Oxygenation and Lung Mechanics in Morbidly Obese Patients Undergoing Bariatric Operations

Effects of Dexmedetomidine on Oxygenation and Lung Mechanics in Morbidly Obese Patients Undergoing Bariatric Operations: A Randomized Controlled Trial

The study aims to investigate the effect of dexmedetomidine on oxygenation and lung mechanics in morbidly obese patients

The patients of interest are morbid obese patients scheduled for bariatric surgery. Dexmeditomidine will be infused intraoperatively after induction of anesthesia. lung mechanics (dead space and compliance) as well as oxygenation (PF ratio) will be monitored intraoperatively and postoperatively

Inclusion Criteria:

- Morbid obese (body mass index > 40) with documented restrictive lung disease scheduled to bariatric operation.

Exclusion Criteria:

• Heart failure
• ِِِِArrhythmia
• Heart block
• Severe liver or kidney impairment.
