<qa>  What is the name of the technique that might lower the need for transfusions?With a major liver or pancreas operation, there is a chance that one will require a transfusion of blood products either red blood cells or plasma. This may be necessary during the operation or a few days after surgery. The surgeons at Memorial Sloan-Kettering Cancer Center perform a very large number of liver or pancreas resections every year and have pioneered techniques that minimize bleeding during the operation. Even so, liver or pancreas operations such as the one that will be undergone carry a 50 chance of requiring a transfusion. A technique that might lower the need for transfusions is called acute normovolemic hemodilution ANH. ANH was first introduced over twenty years ago and has been used in many types of operations, including liver or pancreas resection. The studies done on ANH at other hospitals suggest that it may help conserve blood. Researchers at Memorial Sloan-Kettering Cancer Center are conducting a study to determine if ANH is better than the standard technique that is currently used in all patients. The purpose of this study is to find out which of the two techniques is better.
