Stepwise PEEP vs Sustained Inflation in Bariatric Surgery Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

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

Study 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

Eligibility
