Abstract

Objective: To evaluate the effects of delayed cord clamping on neonatal hyperbilirubinemia in infants born to patients diagnosed with pre-gestational diabetes (type I or type II). Methods: In January 2016, our institution implemented an organization-wide thirty-second delayed cord clamping protocol. This retrospective cross-sectional study represents infants of mothers diagnosed with pre-gestational diabetes who delivered before and after protocol implementation. The study period was from October 2014 to August 2017. The primary outcome was peak neonatal transcutaneous bilirubin (mg/dL) level during neonatal hospital stay. The secondary outcomes included neonatal serum bilirubin (mg/dL), jaundice requiring phototherapy, hypoglycemia, polycythemia, respiratory distress, and neonatal intensive care unit (NICU) admission. A subgroup analysis for outcomes stratified by type of pre-gestational diabetes was also performed. Results: 145 patients were included in the final analysis. The mean peak neonatal transcutaneous bilirubin level was 10.1 mg/dL ± 3.4 mg/dL for immediate cord clamping and 9.5 mg/dL ± 3.4 mg/dL for delayed cord clamping (p =.25). There were no significant differences between groups for neonatal jaundice requiring phototherapy, hypoglycemia, polycythemia, respiratory distress, or NICU admission. No differences were observed in neonatal outcome by subgroup analysis of pre-gestational diabetes type. Conclusion: In our study, there was no significant increase in peak neonatal transcutaneous bilirubin in term (≥37 week) infants of mothers with pre-gestational diabetes after undergoing thirty-seconds of delayed cord clamping. In the absence of contraindications, we advocate for continued use of delayed cord clamping for these infants.
