Vandromme et al reported risk factors associated with massive transfusion in a civilian trauma patient. The authors are from the University of Alabama at Birmingham.
Patient selection: civilian trauma
(1) blood lactate concentration
(2) heart rate in beats per minute
(4) hemoglobin in g/dL
(5) systolic blood pressure in mm Hg
blood lactate concentration
< 5 mmol/L
>= 5 mmol/L
<= 105 beats per minute
> 105 beats per minute
>= 11 g/dL
< 11 g/dL
systolic blood pressure
>= 110 mm Hg
< 110 mm Hg
number of risk factors =
= SUM(points for all 5 parameters)
• minimum number of risk factors: 0
• maximum number of risk factors: 5
• The need for massive transfusion tended to increase with the number of risk factors present.
• The presence of 1 or more risk factors was 96% sensitive and 60% specific.
• The presence of 3 or more risk factors was 60% sensitive and 96% specific.
• The maximum Youden index is with >= 2 risk factors (63%).
