Overview
Brief Summary
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
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.
