Stepwise PEEP vs Sustained Inflation in Bariatric Surgery Patients
Sponsor: Ain Shams University
Summary
Male and female patients Undergoing laparoscopic bariatric surgeries will be subjected for lung recruitment at end of surgery before emergence from anesthesia by two different methods . to evaluate which might be safer and more effective

Conditions
Interventions
sustained inflation recruitement
anesthesiologist adjust the ventilator to manual ventilation mode and ad¬just The ventilator was switched to manual mode, and the airway pressure-limiting valve was set to 30 cmH₂O. A sustained manual inflation was then applied by gradually squeezing the anesthesia reservoir bag over 3-5 seconds until a peak airway pressure (Ppeak) of 30 cmH₂O
Stepwise PEEP
: ventilation will be set to pressure control mode and the driving pressure maintained at 10 cmH2O with an initial PEEP of 5 cmH2O, respiratory rate 8-10, I:E 1-1PEEP will be then increased by 5 cmH2O ev¬ery 30 s until the Ppeak reached 30 cmH2O
