- 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
