@donaldwnelson, your comment yesterday about Coumadin raised a number of issues to deal with carefully.

First, the standard antidote for Coumadin is Vitamin K, which may be administered orally or by other means (shots or IV, for example). Choice of administration as well as of dosage is crucial and needs to be determined by a physician; this is true because there are four levels of severity of bleeding, including clear "frank" red blood out of body wounds as well as invisible internal bleeding. It also depends on whether clotting is needed immediately on an emergency basis or can be allowed to develop in a matter of up to 20 minutes or more.

The standard antidote used by the military is called QuikClot Combat Gauze. It's a heavy-duty blood coagulant for use on combat wounds or other injuries involving heavy bleeding. This may be the substance you remember from the ER treatment of your injury. Professional briefings on the antidote for Coumadin advise that most injuries call for Vitamin K. Regardless of the coagulation agent, professional papers recommend that doctors maintain complete control over the therapy involved with treatment in a medical clinic or ER whenever possible.

Did your ER medical team advise you about the rules of practice for Coumadin? Did they recommend that you consider a anticoagulant other than Coumadin, even though its antidote is not available? Did you ask for prescription for the "combat gauze" and did they provide it?
