🔪 Surgical Apgar Score (SAS)
Predict major postoperative complications with the Surgical Apgar Score.
Surgical Apgar Score (SAS)
Estimated blood loss
Lowest mean arterial pressure
Lowest heart rate
When to use
Flag patients for higher-acuity postoperative monitoring.
How it works
Estimated blood loss (0–3), lowest MAP (0–3) and lowest heart rate (0–4), summed 0–10. ≤ 4 high risk.
Key points
- Derived from intraoperative data at the end of surgery.
- Low scores predict 30-day morbidity and mortality.
- Simple, objective and broadly applicable.
