Read down to the section on James Hinchcliff:
A (nother) fantastic save! (long, a bit technical, surprise ending)
First of all, it’s fantastic to see James Hinchcliffe on the mend. As the story developed, we slowly were made aware of just how bad things had actually been. And now we’re told that he received 14 units of blood. This deserves some background, in order to fully understand just how well things worked for James . . . and draw some conclusions about how things are.
Even intuitively, hearing the number FOURTEEN PINTS is massive. Remember, James’ normal blood volume is probably (to simplify a bit) about 5 liters (for the english unit addicts, a quart is just about a liter). And a unit of red blood cells is about 400 ml. That means that his entire blood volume (5.6 liters to be exact) was replaced, presumably in the first 24 hours after admission. In trauma circles, that’s the standard definition of “massive transfusion”; this definition is not sterile, as it has important implications for management.
