THE PURPOSE of this communication is to describe some experiences of my colleagues and me with the use of exchange transfusion. In our series of 26 exchange transfusions, 24 were performed for the treatment of erythroblastosis fetalis due to Rh sensitization and 2 for other conditions, which will be described later in this paper. This series exhibits several interesting features which will be pointed out in the discussion of the cases.
The 24 cases of erythroblastosis have been divided into four classes: (1) those without an abnormal obstetric history and/or history of blood transfusion (table 1); (2) those with an abnormal obstetric history and/or history of blood transfusion (table 2); (3) those with a history of erythroblastosis with recovery (table 3), and (4) those with a history of fatal erythroblastosis (table 4).
As would be expected, the highest mortality occurred in the last category, in which there were 2 cases and both patients died.
