A method of treating leukaemia or erythroblastosis in newborn babies, where almost all the blood is removed from the body and replaced with healthy blood.
A blood transfusion that is virtually a total replacement of a baby’s blood, as in cases of Rh incompatibility, to avoid permanent damage.
Removal of a person’s blood in small amounts and its replacement with equal amounts of donor blood, esp. exchange transfusion of the fetus (intrauterine exchange transfusion) or the newborn to treat erythroblastosis fetalis (neonatorum) by removing the Rh and ABO antibodies and lysed erythrocytes (red blood cells) and substituting blood with normal oxygen-carrying capacity.
The repeated removal of small amounts of blood, followed by substitution of like amounts of blood from a number of donors, until a large portion of the body’s blood has been replaced.
A test done to determine the functional capacity of the heart in patients who have no symptoms and to help find the cause of chest pain. This test is also used to set up an appropriate exercise program for people who have a healthy heart, as well as those who have heart disease, to strengthen the heart and at the same time prevent further damage through excessive exercise.
A technique for treating hemolytic disease in newborn infants. Using a 20-ml syringe with a three-way tap, Rh positive blood is withdrawn from the baby (via the umbilical vein), ejected, and replaced by 20 ml Rh negative donor blood, without detaching the syringe. By many repetitions of this exchange, red blood cells liable to be destroyed and bilirubin released from those already destroyed are removed, while keeping the baby’s blood volume and number of red cells constant.
The removal of a patient’s entire blood volume (e.g., in sickle cell disease, thrombotic thrombocytopenic purpura, hemolytic disease of the newborn) and its replacement with blood donated by others.
Exchange transfusion is a therapy for newborn haemolytic disease, a critical condition resulting from rhesus incompatibility between an expectant mother and her baby that leads to the breakdown of the baby’s red blood cells. This disease results in perilously high bilirubin levels in the baby’s blood and severe anemia, characterized by reduced hemoglobin, the oxygen-carrying pigment in the blood. Exchange transfusion aims to treat these symptoms by replacing the infant’s blood with rhesus-negative donor blood.
