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

Abstract Background 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. Objective The aim of this study was to equate the effect of pressure controlled ventilation (PCV) vs. volume controlled ventilation (VCV) on respiratory, oxygenation parameters and post operative complications. Patients and Methods This study was conducted on 80 patients who underwent laparoscopic gastric sleeve surgery in Ain Shams University Hospitals. Post induction of Anesthesia, Patients were divided into two groups. The first group mechanical ventilation setting was volume controlled ventilation and the second group mechanical ventilation setting was pressure controlled ventilation. Results The results of our study shows that despite some valuable effects regarding plateau and mean airway pressure with PCV, there is no momentous clinical difference between volume controlled ventilation (VCV) and pressure controlled ventilation (PCV) in obese patients undergoing laparoscopic gastric sleeve surgery. However, pressure controlled ventilation shows slightly more favorable results regarding post extubation oxygen saturation and the decrease of post operative basal atelectasis. It appears that using dual modes would be an epitome approach with lower complications and similar outcomes.
