Local Assessment of Ventilatory Management During General Anesthesia for Surgery

Local Assessment of Ventilatory Management During General Anesthesia for Surgery - a Prospective Observational Multi-center Cohort Study

Objectives

1. To characterize mechanical ventilation practices during general anesthesia for surgery
2. To assess the dependence of intra-operative and post-operative pulmonary complications on intra-operative Mechanical Ventilation (MV) settings

Research questions

• What MV-settings are used during general anesthesia for surgery?
• Do MV-settings vary in and/or between centers?
• Do MV-settings vary internationally?
• Are MV-settings associated with incidence of intra-operative pulmonary complications?
• Are MV-settings associated with incidence of post-operative pulmonary complications?

Inclusion Criteria:

• Age ≥ 18 years
• All surgical procedures requiring invasive mechanical ventilation (MV)during general anesthesia for laparoscopic or non-laparoscopic surgery.
• This includes MV performed with supra-glottic devices (e.g. laryngeal mask)
• This includes patients receiving MV at the onset of the procedure (e.g. Intensive Care Unit patients)
• This includes patients who will receive one-lung ventilation during the procedure

Exclusion Criteria:

• Obstetric surgical procedures or any procedure during pregnancy
• Surgical procedures outside the operating room
• Surgical procedures involving extra-corporal circulation
