OBJECTIVE: To determine the rates of adverse events associated with neonatal exchange transfusions performed for hyperbilirubinemia. STUDY DESIGN: Retrospective chart review of 55 neonates who underwent 66 exchange transfusions at two perinatal centers in Cleveland between 1992 and 2002. Demographic data, causes of jaundice, details of exchange method, and adverse events occurring within one week of exchange were recorded. At the time of exchange, 62% of infants had other neonatal morbidities. Outcomes were stratified according to gestational ages < or =32 weeks, 33 to 36 weeks, and > or =37 weeks. RESULTS: Overall, 74% of exchanges were associated with an adverse event. The most common events were thrombocytopenia (44%), hypocalcemia (29%), and metabolic acidosis (24%), of which 69%, 74%, and 44%, respectively, required treatment. There were two serious adverse events, both in infants with other serious neonatal morbidities: seizures in one infant and the death of a critically ill preterm infant (body weight 731 g, gestational age 25 weeks). There were no cases of sepsis, necrotizing enterocolitis, or cardiac arrest. Adverse events were more frequent in exchanges done on preterm infants: < or =32 weeks (87%), 33 to 36 weeks (78%), and > or =37 weeks (67%), and in infants with other neonatal morbidity (79% vs 57%; P=.08). Controlling for neonatal morbidity, we found the odds of an adverse event were significantly higher when both umbilical venous and arterial catheters were used compared with other methods of exchange (88% vs 58%; OR, 5.17; 95% CI, 1.1, 34.2; P=.03). CONCLUSIONS: The majority of adverse events associated with exchange transfusion are laboratory abnormalities and are asymptomatic and treatable.
New data support restructuring the approach toward diagnosis and management of hyperbilirubenia in the term neonate to make it more physician-friendly and gain wider implementation. The authors advocate clear criteria for patient safety, preventive approaches, and timely interventions. Structural changes to facilitate a system-based approach should include predischarge bilirubin management; follow-up bilirubin management; and lactational support and nutritional management. The authors advocate total serum bilirubin screening and a scoring system based on clinical risk factors as predischarge screening strategies; we should screen all babies for hyperbilirubinemia and for targeted follow-up based on an hour-specific total serum bilirubin measured for risk assessment. We should also provide focused universal education emphasizing adequate lactational nutrition, to decrease severe hyperbilirubinemia and thus prevent kernicterus.
A 3-month-old infant of 33 weeks' gestation was hospitalized with pneumonia caused by Bordetella pertussis. Respiratory insufficiency worsened, and on hospital day 3, there was severe pulmonary dysfunction (arterial oxygen pressure/fraction of inspired oxygen ratio: 120), extreme leukocytosis (white blood cell count 104,000/mm3), and severe pulmonary hypertension as assessed by 2-dimensional echocardiogram. A double volume exchange transfusion was performed to reduce the leukocyte mass. Oxygenation began to improve during the exchange and continued to improve over the ensuing 31 hours (arterial oxygen pressure/fraction of inspired oxygen ratio: 280). The white blood cell count fell dramatically after the exchange, and the rate of rise was slower after exchange therapy compared with preexchange.
