Clinical takeaway

Derived from intraoperative data at the end of surgery.

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.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

  • Risk：High risk of major complication/death
  • Note：≤ 4 is associated with markedly higher 30-day morbidity/mortality — consider closer postoperative monitoring.

FAQ

Frequently asked questions

What are the limits and cautions when using Surgical Apgar Score (SAS)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Surgical Apgar Score (SAS) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Surgical Apgar Score (SAS) calculated in practice? Can you show a worked example?
Inputs: Estimated blood loss 601–1000 mL (1), Lowest mean arterial pressure 40–54 (1), Lowest heart rate 66–75 (2) → Result: Surgical Apgar 4 /10（Risk: High risk of major complication/death, Note: ≤ 4 is associated with markedly higher 30-day morbidity/mortality — consider closer postoperative monitoring.） Inputs: Estimated blood loss > 1000 mL (0), Lowest mean arterial pressure < 40 mmHg (0), Lowest heart rate > 85 (0) → Result: Surgical Apgar 0 /10（Risk: High risk of major complication/death, Note: ≤ 4 is associated with markedly higher 30-day morbidity/mortality — consider closer postoperative monitoring.）
