People loose blood in accidents , the amount needed for resuscitation is still hazy for acute blood loss..Is there a formulae or developed index to decide amount to be requested from Blood Bank for transfusion?
Systolic blood pressure is the best indicator in the prehospital care environment. In-hospitable blood pressure and HCT are good indicators. If you don't use a ratio of 1:1:1 red cells, plasma, platelets, monitoring pt, ptt and platelets will help prevent dilutional coagulopathy. You can add more sophisticated testing but they take time, and in the face of acute blood loss, simple is better. You might also consider reinfusing any blood collected from the chest.
i feel there is need to develop a formulae just the same as that of Burns , for blood transfusion in acute blood loss for standardization .
George people have gone back to 1:2:1 or 1:1:1 to prevent coagulopathy. I believe 3:1:1 may work just as well. The formular was 10:4:10 for many years.
