Summary

The aim of this study is to evaluate the effectiveness of intraoperative individualized positive end-expiratory pressure (PEEPIND) titration, compared to fixed positive end-expiratory pressure of 5 cmH2O, on oxygenation, hemodynamic variables, and early postoperative complications in obese patients undergoing laparoscopic bariatric surgery.

Conditions

  • Positive End-expiratory Pressure
  • Hemodynamic Variable
  • Postoperative Atelectasis
  • Laparoscopic Bariatric Surgery

Interventions

OTHER

Positive end-expiratory pressure 5 (PEEP 5)

Fixed positive end-expiratory pressure of 5 cmH2O will be maintained throughout the duration of surgery

OTHER

Individualized positive end-expiratory pressure (PEEPIND)

Patients will receive the individualized positive end-expiratory pressure. Titration process will be started after establishment of pneumoperitoneum: setting the initial PEEP to 5 cmH2O, then increasing positive end-expiratory pressure (PEEP)according to the gradient of 2 cmH2O every 3 min, calculating static compliance (Cstat) according to the formula: \[Cstat = VT/Pplat - PEEP\] (Pplat = plateau pressure), then gradually increasing positive end-expiratory pressure , until the calculated Cstat shows a downward trend, set its previous PEEP (corresponding to PEEP for high Cstat) as the optimal PEEPIND for this patient. The highest PEEP is limited to 20 cmH2O
