NCT06234774

Brief Summary

This secondary analysis aims to identify factors associated with the development of postoperative pulmonary complications (PPCs) in patients undergoing abdominal surgery, pooling and analyzing the data of two worldwide prospective studies, the 'Epidemiology, Practice of Ventilation and Outcome for Patients at Increased Risk of Postoperative Pulmonary Complications' (LAS VEGAS, NCT01601223) and the 'Assessment of Ventilatory management during general AnesThesia for Robotic surgery and its effects on postoperative pulmonary complications' (AVATaR, NCT02989415). The primary aim is to compare the incidence of PPCs between patients undergoing non-robotic surgery versus patients undergoing robot-assisted surgery. One secondary aim is to determine which factors are associated with the occurrence of PPCs. The investigators hypothesize that differences in the occurrence of PPCs between the two surgery groups are more driven by differences in duration of anesthesia than by the intensity of ventilation.

Study Population

Surgical patients receiving invasive mechanical ventilation for laparoscopic or robot-assisted laparoscopic surgery

You may qualify if:

  • All adult patients receiving invasive ventilation (via either an endotracheal tube or supraglottic device) during general anaesthesia for elective or non-elective surgery.

You may not qualify if:

  • patients not undergoing laparoscopic surgery in LAS VEGAS, and not undergoing abdominal RAS in AVATaR;
  • patients undergoing combined thoracic-laparoscopic surgery and patients in whom the intervention was converted from laparoscopic or RAS to open surgery are excluded;
  • patients that received recent ventilation before surgery;
  • patients with incomplete ventilation datasets not allowing the computation of intensity of ventilation, and patients with an incomplete follow-up for PPCs are also excluded.
