It's still in trials, and holds much promise, but I agree with this statement:
"Once blood is available, they profess, randomization should be reserved for consenting subjects."
To offer polyheme, an unproven therapy, IN PLACE of the standard of care, blood, without consent, is unethical. Until such time as the FDA approves it as a standard of care, critically ill patients should not be forced to 'hope' that THEY aren't the guinea pigs of some drug trial.
Kind of reminds me of testing the affects of nuclear fallout by using unwitting test subjects. Just because the gov't approves of such test does NOT mean that they are truly in YOUR best interests.
