Relationship Between Delayed Cord Clamping at Birth and Neonatal Bilirubin Levels in Parturients With a Prior Child Requiring Therapy for Neonatal Jaundice

Randomized Controlled Trial to Evaluate the Relationship Between Delayed Cord Clamping at Birth and Neonatal Bilirubin Levels in Parturients With a Prior Child Requiring Therapy for Neonatal Jaundice

The purpose of the study is to determine if neonates (who already have an increased risk of hyperbilirubinemia due to mother's history of having previous neonate who received phototherapy for hyperbilirubinemia) have higher bilirubin levels 24 hours after birth with delayed cord clamping.

Study Overview

• Status: Completed
• Conditions: Hyperbilirubinemia, Neonatal; Jaundice, Neonatal
• Intervention / Treatment: Procedure: Delayed cord clamping; Procedure: Early cord clamping

• Study Type: Interventional
• Enrollment (Actual): 20
• Phase: Not Applicable

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 40 years (Adult)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• mothers delivering at 35 weeks or greater
• mothers who have had at least 1 previous child that received phototherapy for hyperbilirubinemia
• multiple gestations can be included unless the neonate does not meet criteria for delayed cord clamping as described below or due to concerns about safety of delayed cord clamping for timing of delivery of the 2nd twin (ie: 2nd twin requires immediate delivery intervention)

Exclusion Criteria:

- Neonates who do not meet criteria for delayed cord clamping (any infant that any provider in the room felt needed evaluation by the neonatal transport team immediately so that the infant would be handed off for resuscitation. If the patient required delivery by cesarean section the delayed cord clamping protocol would be abandoned).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Delayed cord clamping	Procedure: Delayed cord clamping; The umbilical cord will be clamped after 60 seconds after birth
