LAS VEGAS: Local Assessment of Ventilatory Management During General Anesthesia for Surgery and effects on Postoperative Pulmonary Complications: a Prospective Observational International Multi–center Cohort Study

Primary Outcome Measures

  • Post-operative pulmonary complications, possibly related to ventilation strategy [ Time Frame: Post-operative on day of surgery, day 1, 2,3,4,5 and day 28 ] [ Designated as safety issue: No ]
  • Effect of Mechanical Ventilation settings during general anesthesia for surgery on the incidence of post-operative pulmonary complications (new or prolonged invasive or non-invasive mechanical ventilation, need for oxygen therapy, respiratory failure, pneumonia, ARDS 'Acute Respiratory Distress Syndrome', pneumothorax) Defined post-operative pulmonary complications are recorded from the medical chart on day 0, 1, 2, 3, 4 and 5 after surgery. On day 28 length of hospital stay and in hospital death are assessed.

Secondary Outcome Measures

  • Intra-operative complications related to the ventilation strategy [ Time Frame: Time point(s) at which outcome measure is assessed is is: Day of surgery, day 1, 2, 3, 4, 5 and 28 after surgery ]
  • Mechanical ventilation-settings during general anesthesia for surgery [ Time Frame: During the surgical procedure, from moment of to tracheal extubation or discharge from operation room (in case patient remains on mechanical ventilation) ]
  • Variation of applied MV settings within centers
  • Variation of applied MV settings between centers on an international basis

LAS VEGAS study is registered on website: NCT 01601223
