Abstract
OBJECTIVE: To characterize the prevalence of exchange transfusion (ET), clinical characteristics of infants receiving ET, and ET-associated morbidity and mortality. STUDY DESIGN: We conducted a multicenter cohort study of infants ≥23 weeks of gestational age (GA) with hyperbilirubinemia who underwent ET within 30 days of birth from 1997 to 2016. We examined clinical characteristics and adverse events after ET. We used multivariable logistic regression to examine the association between clinical risk factors and death. RESULT: A total of 1252 infants were included; 4% died within 7 days of ET and 6% died before discharge. Compared with infants ≥37 weeks of GA, infants ≤29 weeks of GA had greater odds of death (adjusted odds ratio [95% confidence interval] = 20.08 [7.32, 55.07]). CONCLUSIONS: Infants ≤ 29 weeks of GA had greater odds of death following ET compared with term infants. These data will support clinicians in evaluating risks and prognosis for infants who require ET.
