Brief Summary

Oxygen therapy is administered to all patients during general anesthesia to maintain tissue oxygenation and prevent hypoxia and ischemia. However, liberal use of oxygen may lead to hyperoxia and some studies suggest that supranormal levels of arterial oxygen saturation may lead to complications. In this post hoc substudy of the VISION cohort, we plan to assess the association between perioperative inspired oxygen fraction (FiO2) and myocardial injury after non-cardiac surgery (MINS).

Secondary Outcomes (5)

  • All-cause mortality

    Within 30 days after surgery

  • Myocardial infarction

    Within 30 days after surgery

  • MINS

    Within 30 days after surgery

  • Rehospitalization for vascular reasons

    Within 30 days after surgery

  • Pneumonia

    Within 30 days after surgery

Other Outcomes (9)

  • Vascular mortality

    Within 30 days after surgery

  • Non-fatal cardiac arrest

    Within 30 days after surgery

  • Cardiac revascularization procedure

    Within 30 days after surgery

  • +6 more other outcomes
