Recent prospective cohort study of 1218 patients undergoing major NONCARDIAC surgery (Click here) or on link below

  • Undiagnosed OSA was associated with increased risk of postoperative cardiac complications, including:
    • Myocardial injury, cardiac death, heart failure, VTE, AF, stroke
  • Rates of postoperative cardiac complications at 30 days:
    • Severe OSA patients: 30.1%
    • Moderate OSA patients: 22.1%
    • Mild OSA patients: 19%
    • Patients without OSA: 14.2%
  • Regional anaesthesia and avoidance of postoperative opioids in patients with OSA has not been associated with better outcomes

STOP-BANG (OSA Screening tool)

  • Score of > = 5 classifies as high risk for OSA
  • Validated tool
    • Sensitivity and Negative Predictive Value >90% for moderate-severe OSA
    • Positive Predictive Value >78% for all patients
