Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess whether pressure controlled ventilation-volume guaranteed (PCV-VG) has a lesser incidence of postoperative pulmonary complications (POPC) up to 7 days of surgery over a volume controlled ventilation (VCV).Timepoint: Incidence of postoperative pulmonary complications (POPC) at post operative day 0, 1, 2, 3, 4, 5, 6 and 7. | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess duration of hospital stay.Timepoint: At hospital discharge.;To assess hospital mortality.Timepoint: At hospital mortality.;To assess intraoperative & postoperative oxygenation status.Timepoint: Intraoperatively and 30 minutes after extubation.;To assess intraoperative lung mechanics i.e. compliance, airway pressures, driving pressures and mechanical power.Timepoint: 10 min after induction, hourly thereafter, and at the end of surgery before extubation.;To assess oxygen free days at day-28 post randomization or till hospital discharge.Timepoint: At day-28 post randomization or till hospital discharge.;To assess the association of mechanical power and postoperative pulmonary complications (POPC).Timepoint: Upto 7 days after surgery.;To assess the preoperative and postoperative lung ultrasound aeration score.Timepoint: Before induction and 30 minutes after extubation.;To characterize the postoperative pulmonary complications according to the European Perioperative Clinical Outcomes definitions.Timepoint: Upto 7 days after surgery. | — |
