From: Prediction of pre-hospital blood transfusion in trauma patients based on scoring systems
Scoring system | Variables | Calculation |
---|---|---|
SI (Shock Index) | Heart rate (HR) Systolic blood pressure (SBP) | HR ÷ SBP |
AGE–SI (Age multiplied by Shock Index) | Age Shock index | (HR ÷ SBP) ∙ Age |
PP (Pulse Pressure) | Systolic blood pressure Diastolic blood pressure (DBP) | SBP − DBP |
rSI–G (reversed Shock Index multiplied by GCS) | Systolic blood pressure Glasgow Coma Scale | (SBP ÷ HR) ∙ GCS |
MGAP (Mechanism; GCS; Age; Systolic blood pressure) | Mechanism of injury (M): | M + G + A + P sum of points from each component |
Blunt: + 4 pt Penetrating: 0 pt | ||
GCS (G): 3–15 pt AGE (A): < 60y: + 5 pt > 60y: 0 pt | ||
Systolic blood pressure (P): > 120 mmHg: + 5 pt 60–120 mmHg: + 3 pt < 60 mmHg: 0 pt |
