Have you ever heard of Polyheme Resuscitative fluid for acute blood loss?

  1. PolyHeme« is a human hemoglobin-based temporary oxygen-carrying red blood cell substitute in development for the treatment of life-threatening blood loss when an oxygen-carrying fluid is required and red blood cells are not available.
    PolyHeme« is a solution of chemically modified human hemoglobin which simultaneously restores lost blood volume and hemoglobin levels and is designed for rapid, massive infusion.

    It's still in trials, and holds much promise, but I agree with this statement:

    http://www.bioethics.net/journal/j_articles.php?aid=998

    "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.

    There was a big article on it in scientific america or popular science, -something like that.
    It carries oxygen to the brain very quickly because it's molecules are smaller than blood molecules. I understand it can have amazing results. (Oxyegn to the brain twice as fast as blood?)
    I believe at this time there are several major contenders in the research for an artifical blood.
    I read the article awhile ago- & I'm just a student nurse so I don't have advanced medical training, but I remember thinking damn I want that.

    These artifical blood products are worth the research dollars.

    Exactly! Patients should be made aware of the treatment they are to be given. Giving the polyheme without consent of the patient is considered battery in my book.
