Conventional versus protective lung ventilation strategy in laparscopic cholecystectomy surgery

Background:Laparoscopic cholecystectomy is a commonly performed surgery that isassociated with pneumoperitoneum‑induced respiratory compromise and altered pulmonarymechanics strategies have been investigated for use during laparoscopic cholecystectomy. TheObjectives: 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 undergoingelective laparoscopic cholecystectomywith BMI 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 betweenoxygenation in both groups. Post-operative oxygenation in protective ventilation (group 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 asit was associated with better oxygenation in the post-operative in laparoscopiccholecystectomy
