🩸 ABC Score (Massive Transfusion)
Predict massive transfusion need in trauma with the ABC score.
ABC Score (Massive Transfusion)
Penetrating mechanism
Systolic BP ≤ 90 mmHg
Heart rate ≥ 120 bpm
Positive FAST
When to use
Trigger early massive transfusion protocol activation.
How it works
Penetrating mechanism, SBP ≤ 90, HR ≥ 120, positive FAST — each 1 point. ≥ 2 predicts massive transfusion.
Key points
- Uses only bedside data — no laboratory values.
- Intentionally simple and sensitive.
- ≥ 2 should prompt MTP activation.
