Blood loss of >40% (>2000ml)
|
rapid volume replacement including PRBC is required
|
|
|
30-40-% (1500-200) loss
|
rapid volume replacement with crystalloids
|
|
|
15-30 % loos (800-1500)
|
need to transfuse crystalloids or synthertic colloids; need for RBC is unlikely unless the patient has preexisting anemia
|
|
|
<15 % loss (<750 ml)
|
no need for transfusion unlessvolume loss is superimposed on pre existing anemia or pt is unable to compensate due to severe cardiac or respiratory loss
|
|
|
Hgb <7 g/dL (Hct<21%)
|
PRBC transfusion is indicated. If the patient is otherwise stable, the patient should receive 2 units of PRBCs and the Hgb/Hct reassessed
|
|
|
Hgb 7-10 g/dL (hct 21-30%)
|
transfusion strategy is unclear. Need to transfuse is based on many variables
|
|
|
Hgb>10 g/dL (Hct>30%) RBC
|
transfusion is not indicated
|
|
|
high risk patients > 65 may not tolerate anemia such patients may be transfused when their Hgb is ?
|
< 8 g/dL (Hct<24%)
