Hyperbilirubinemia, NeonatalNCT03741803
Relationship Between Delayed Cord Clamping at Birth and Neonatal Bilirubin Levels in Parturients With a Prior Child Requiring Therapy for Neonatal Jaundice
A study testing Delayed cord clamping and Early cord clamping in people with Hyperbilirubinemia, Neonatal and Jaundice, Neonatal, run by The University of Texas Health Science Center, Houston at 1 site in United States.
Trial summary
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.

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 40 years
- Women only
- No healthy volunteers
- Adult
Who may be able to join
- 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)
Who cannot join
- 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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Delayed cord clampingProcedure or surgery
The umbilical cord will be clamped after 60 seconds after birth
Early cord clampingProcedure or surgery
The umbilical cord will be clamped as soon as feasible after birth, usually within the initial 15 seconds after birth.
| Study group | Role | What they receive |
|---|---|---|

Questions about this trial
What is this clinical trial studying?
A study testing Delayed cord clamping and Early cord clamping in people with Hyperbilirubinemia, Neonatal and Jaundice, Neonatal, run by The University of Texas Health Science Center, Houston at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Neonatal bilirubin level (time frame: 24 hours after birth). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2026; AzTrials last refreshed its copy on 7 Nov 2026.
