Conventional versus protective lung ventilation strategy in laparscopic cholecystectomy surgery

Background:Laparoscopic cholecystectomy is a commonly performed surgery that is associated with pneumoperitoneum‑induced respiratory compromise and altered pulmonary mechanics strategies have been investigated for use during laparoscopic cholecystectomy. The Objectives: to study the effects of low tidal volume with positive end-expiratory pressure (PEEP) on arterialblood gases of patients undergoing laparoscopic cholecystectomy. Patients and Methods: This is a prospective study that included 60 adult patients undergoing elective laparoscopic cholecystectomywith BMI< 30at general surgery department in Qena university hospital “between October 2016to April 2018”, the Sixty patients were assigned to two groups:group Athe tidal volume was 6 mL/kg, with PEEP of 5 cm of H2O(n = 30), group < br />B received the tidal volume was 10 mL/kg, and the PEEP was set at 0 cm of H2O (n = 30). Patient hemodynamics, pulmonarymechanics, and arterial blood gases were measuredpreoperative, intraoperative and post-operative. Results:All cases were completed successfully.Study showed significance between oxygenation in both groups. Post-operative oxygenation in protective ventilation (group < br />A)Mean Post P aO2 in group A was 91.1(± 5.1)mmHg, while in group B was 80.2(±4.2) mmHg, p value (0.001). Conclusion:Study found that protective ventilation was superior to conventional ventilation as it was associated with better oxygenation in the post-operative in laparoscopic cholecystectomy
