(Another type of autologous transfusion is described in Donating Blood.) Blood substitutes But some studies have found tumor cells in blood salvaged during cancer operations, and this isn’t something that can be done for all patients. It cuts down on the need for transfusions from other donors. Giving a person back their own blood is called an autologous transfusion. Sometimes this lost blood can be “salvaged” or saved by collecting it with a special machine and giving it back into the patient. Patients getting surgery sometimes need transfusions to replace blood lost during or after the operation. Intra-operative or post-operative blood salvage And when they are used, they are given for as short a time as possible. Growth factors generally cost a lot more than transfusions.īecause of these drawbacks, certain growth factors are not used in people whose treatment is expected to cure their cancer.Some growth factors might cause certain types of cancer cells (such as lymphocytic leukemia, multiple myeloma, head and neck cancer, breast cancer, cervical cancer, and some kinds of lung cancer cells) to grow more quickly.People who have severe bone marrow disease may not respond to the growth factors because they don’t have enough blood-producing cells in their bone marrow.Unlike transfusions, growth factors often take many days or weeks to raise blood counts, so they may not be useful in people who need their blood cell levels raised quickly, such as those who are actively bleeding.But they have some drawbacks that may limit their use in some cases: Growth factors may help patients who would otherwise need transfusions. Growth factors can be used to boost red blood cell, white blood cell, or platelet counts. Man-made versions of some of these growth factors are available to help people with low blood cell counts. The body naturally makes hormone-like substances called hematopoietic growth factors that cause the bone marrow to make more blood cells. They boost fluid volume and help with circulation, but don’t carry oxygen or raise the number of blood cells. The solutions are put right into the bloodstream through a vein. This may be treated or prevented by giving solutions to expand fluid volume in order to keep blood circulating through vital organs. When a patient has lost a lot of fluids, the body can go into a type of shock. ![]() In some cases, options other than blood product transfusions may be used.
