Brief Summary

Evidence for benefited newborns following delayed cord clamping (DCC), including increasing hemoglobin and hematocrit levels, improving iron stores, and decreasing need for blood transfusion and incidence of intraventricular hemorrhage, in term or preterm infants led the American College of Obstetricians and Gynecologists (ACOG) to recommend a delayed cord clamping at least 30-60 seconds in vigorous term and preterm infants at birth. Although DCC has been found to be beneficial to infants, the additional blood provided by DCC could increase the incidence of jaundice that requires phototherapy and the hyperbilirubinemia, and the time prolonged by DCC might jeopardize timely resuscitation efforts, if needed. The acid-base status in umbilical cord blood at birth reflects the newborn's aerobic and anaerobic intrauterine metabolisms and is an objective measure of the fetal exposure and response to hypoxia during labour. Gestational diabetes mellitus (GDM) is a condition in which glucose intolerance develops during pregnancy. It has been estimated in 2009 that nearly 7% of pregnancies are complicated by diabetes and approximately 86% of these cases represented women with GDM. The Hyperglycemia and Adverse Pregnancy Outcome study (HAPO) revealed that the infants of diabetic mothers (IDMs) are at increased risk of neonatal hypoglycemia, hyperbilirubinemia, shoulder dystocia, and birth trauma. And newborns to diabetic mothers are at increased risk of neonatal respiratory distress syndrome (RDS) and hypoxia, a major cause of admission in neonatal intensive care units. There is little direct evidence on the implementation of delayed umbilical cord clamping in the risk group of IDMs. Therefore, it no clear that the effectiveness and impairment of DCC in IDMs. Therefore, the investigators conducted a prospective study in performing DCC in the infants of diabetic mothers versus the newborns with early cord clamping (ECC) to assess the effect of DCC on neonatal bilirubin levels, hyperbilirubinemia incidence, acid-base status and hypoxia in IDMs.

Outcome Measures

Primary Outcomes (4)

  • neonatal cord acid-base status

    arterial cord samples were analyzed within 15 min by blood gas analyzer

    within the 15 minutes after delivery

  • neonatal transcutaneous bilirubin level

    The transcutaneous bilirubin was measured by the uniform TcB device three times a day

    within the 1 to 3 days of age

  • Number of infants with neonatal jaundice requiring phototherapy

    the infants need phototherapy because of high bilirubin level

    within the 1 to 3 days of age

  • Number of infants with neonatal hyperbilirubinemia

    the infants need phototherapy because of high bilirubin level

    within the 1 to 3 days of age

Secondary Outcomes (1)

  • neonatal initial blood glucose levels

    within the 30 minutes after delivery

Study Arms (2)

delayed cord clamping

EXPERIMENTAL

OTHER
