Surgical Apgar Score
Predict major complications and death within 30 days of general or vascular surgery, using intraoperative values at the end of the operation.
Indication
- Predict major complications and death within 30 days of general or vascular surgery, using intraoperative values at the end of the operation.
Criteria
- id: ebl; label: Estimated blood loss (mL); type: options; options: value: 0; label: ≥1000; value: 1; label: 601–999; value: 2; label: 101–600; value: 3; label: ≤100
- id: map; label: Lowest mean arterial pressure (mmHg); type: options; options: value: 0; label: <40; value: 1; label: 40–54; value: 2; label: 55–69; value: 3; label: ≥70
- id: hr; label: Lowest heart rate (bpm); type: options; options: value: 0; label: >85; value: 1; label: 76–85; value: 2; label: 66–75; value: 3; label: 56–65; value: 4; label: ≤55
Interpretation
- function(score) { if (score <= 4) return { risk: score + '/10', tier: 'Very High Risk', action: '~75% major complication rate, ~14% mortality. Consider ICU admission and intensive monitoring.', color: 'red' }; if (score <= 6) return { risk: score + '/10', tier: 'High Risk', action: '~27% complication rate, ~4% mortality. Consider step-down unit.', color: 'yellow' }; if (score <= 8) return { risk: score + '/10', tier: 'Moderate Risk', action: '~12% complication rate, ~1% mortality. Standard monitoring.', color: 'yellow' }; return { risk: score + '/10', tier: 'Low Risk', action: '~4% complication rate, ~0.5% mortality. Routine post-op care.', color: 'green' }; }
Clinical pearls
- Predicts outcomes as well as more complex pre-operative scoring systems
- Calculated immediately at the end of the case — enables proactive post-op planning
- A score <7 should trigger consideration of ICU vs floor admission
- Complements the pre-operative RCRI by adding intraoperative risk data
