Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Changes in Intraoperative Mechanical Power During vNOTES Surgery | Intraoperatively, from immediately after endotracheal intubation to the end of surgery, at six predefined time points (T0-T5). | Mechanical power (J/min) will be calculated using recorded mechanical ventilation parameters. Changes in mechanical power associated with pneumoperitoneum and Trendelenburg positioning will be evaluated at six predefined intraoperative time points (T0-T5). Kopyala |
| Secondary | Changes in Intraoperative Driving Pressure | Intraoperatively, from immediately after endotracheal intubation to the end of surgery, at six predefined time points (T0-T5). | Description: Driving pressure (cmH₂O) will be calculated as plateau pressure minus positive end-expiratory pressure (Pplat - PEEP). |
| Secondary | Changes in Static Respiratory System Compliance | Intraoperatively, from immediately after endotracheal intubation to the end of surgery, at six predefined time points (T0-T5). | Static respiratory system compliance (mL/cmH₂O) will be calculated using tidal volume and driving pressure (VT/\[Pplat - PEEP\]). |
| Secondary | Changes in Dynamic Respiratory System Compliance | Intraoperatively, from immediately after endotracheal intubation to the end of surgery, at six predefined time points (T0-T5). | Dynamic respiratory system compliance (mL/cmH₂O) will be calculated using tidal volume and the difference between peak airway pressure and PEEP (VT/\[Ppeak - PEEP\]). |
