Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare volume controlled-ventilation (VCV) and pressure-controlled ventilation (PCV) in terms of pulmonary gas exchange, respiratory mechanics and arterial blood gas values in patients undergoing laparoscopic bariatric surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Today, morbid obesity has become a global problem. It is not clear which mechanical ventilation mode will be used in bariatric surgery, which is one of the treatment options of these patients. VCV is the most commonly used mode to ventilate anesthetized patients. However, especially in obese patients, high airway pressures and hypoxia may occur due to increased intrapulmonary shunts. Therefore, we aimed to investigate the potential of PCV strategy to improve pulmonary gas exchange, respiratory mechanics and arterial blood gas values according to VCV in patients undergoing bariatric surgery.
