Exchange transfusion - series

Neonatal jaundice is a common problem among infants immediately after birth. It is the result of the inability of the neonatal liver to clear bilirubin, a breakdown product of blood cells, from the blood. Neonatal jaundice is usually a self-limiting, mild disorder. The most commonly used treatment is ultraviolet light exposure, in which the infant is placed under an ultraviolet lamp for a few hours each day. The ultraviolet light breaks down bilirubin into a form which the infant liver can process and excrete.

The infant is laid on his or her back, usually under a radiant warmer. The umbilical vein is catheterized with a fluid-filled catheter. The catheter is connected to an exchange transfusion set, incorporating lines to and from a waste container and a pack of donor blood. These are connected by means of a four-way stopcock, to which is also attached the syringe used to remove and replenish the infant's blood. The exchange transfusion now goes ahead in cycles, each of a few minutes duration. Slowly the infant's blood is withdrawn and the fresh, pre-warmed blood or plasma is injected. After the exchange transfusion, an umbilical catheter may be left in place in case the procedure needs to be repeated within a few hours.
