The mortality of exchange transfusions.

A prospective study of the effect and mortality of exchange transfusion was carried out in the Kandang Kerbau Hospital, Singapore. Altogether 140 exchange transfusions were performed on 122 infants. The exchanges were done for hyperbilirubinaemia due to "idiopathic" jaundice, ABO haemolytic disease, and glucose-6-phosphate dehydrogenase deficiency. Eight infants deteriorated during the exchange, in three of whom the procedure had to be terminated prematurely. Two deaths occurred two days after the exchange--the procedure being partly responsible in one case; necrotizing enterocolitis was present in addition to the kernicterus. Exchange transfusion is not without hazards, and should be performed carefully with close monitoring of the clinical status of the infant during and immediately after the procedure.
