Hip FAQ

Question:

I'm going to have a total hip and a total knee joint replacement at the same time on the same leg. I know this is unusual and most people do one at a time. My doctor's biggest concern is blood clots. Mine is blood loss and transfusion with the chance of getting AIDs or hepatitis. What are my chances of this happening?

Answer:

To prevent blood clots, an intravenous drug called heparin is used. This prevents the blood from clotting and could result in blood loss. There could even be enough blood loss to need a blood transfusion. Many doctors advise patients to donate their own blood at least three weeks before the surgery. Family members can also be tested and donate on your behalf. Blood testing for hepatitis has reduced problems with blood transfusion as a source for hepatitis. Likewise, donor screening has reduced the risk of HIV by infusion. This risk is very low (one in one million transfusions). There's also a new drug out called Epogen that can increase red blood cells. This has reduced the need for blood transfusion for many patients having joint replacement surgery. Richard D.
