[Complications of exchange transfusion in term and preterm newborns]

Exchange transfusion has an important role in the treatment of hyperbilirubinemia of the newborn. It is used in attempts to prevent kernicterus when bilirubin levels are high. We describe our experience in 203 exchange transfusions performed on 143 infants (81 males and 62 females) with hyperbilirubinemia during 1983-1992. In only 30% of cases was there a specific etiological diagnosis of the jaundice based on a positive Coombs test, G6PD deficiency, or the presence of sepsis or maternal diabetes; the rest were idiopathic. 57% of the neonates were premature (26-36 weeks of gestation). Premature neonates underwent more transfusions than full-term infants (1.6 vs 1.2). There was no direct death from exchange transfusion; morbidity was 6.3% (including bradycardia, apnea, thrombocytopenia, hypoglycemia and hyponatremia). Most complications occurred in preterm infants and those severely ill. All complications were treated immediately and there were no sequelae.
