Capillary Lactate and Transfusion Needs

Brief Summary:

13% of injured normotensive patients arriving in emergency unit need mass blood-transfusion of six or more units of packed Red Blood Cells. It is currently difficult to predict the need for such a mass blood-transfusion. Indeed hemoglobin point of care testing (hemocue) and blood pressure can be normal during the first hours despite intensive bleeding.

It's well known that blood or arterial lactate measures correlate with trauma severity but these measures are not available in a pre-hospital setting. The investigators want to test whether capillary lactate measures also correlate with trauma severity and can therefore predicts earlier transfusion needs.

Group/Cohort Intervention/treatment
Injured patient admitted in vital emergency unit Other: Capillary lactate level
Use of capillary sample to determine lactate level upon arrival at vital emergency unit and at 2 hours

Primary Outcome Measures :
  1. Transfusion of 6 or more units of packed Red Blood Cells (RBC) [ Time Frame: 48 hours ]

Secondary Outcome Measures :
  1. arterial lactate measures [ Time Frame: upon arrival at the vital emergency unit ]
  2. injury scores (ISS,SOFA) [ Time Frame: 24h ]
  3. transfusion of 4 units of packed RBC [ Time Frame: 48 hours ]
  4. blood lactate measure [ Time Frame: upon arrival at vital emergency unit ]
  5. Intensity of medical care [ Time Frame: upon arrival at vital emergency unit ]
    Body scan Central venous catheterisation arterial catheterisation

  6. Bleeding Predictive Score [ Time Frame: upon arrival at vital emergency unit ]
    3 questions are asked to the doctor in emergency room. Could patient be admitted directly at the CT scan ? Do you think that the patient need transfusion ? If Yes : and how many units ? Do you think that the patient will be hospitalized in an intensive care unit after the emergency room?

  7. Mortality [ Time Frame: 28 days ]
