Comparison Between Volume Controlled Ventilation And Pressure Controlled Ventilation In Morbidly Obese Patients Undergoing Laparoscopic Gastric sleeve Surgery

Abstract

Although numerous studies conducted in the past years, there is no superior guideline that indicates the best ventilation mode during laparoscopic anesthesia inobese patients. There are numerous studies with dissimilar controversial points. The management of oxygenation in a morbid obese patient undergoing laparoscopic procedures presents many challenging aspects to the anesthetist. To facilitate Laparoscopic surgeries, the patient must be positioned in steep (40°) Trendelenburg position for some time. When combined with pneumoperitoneum, it can result in unfavorable respiratory and hemodynamic consequences such as decreased lung compliance, higher airway pressures, hypercarbia, hypotension and increased central venous pressure.
