What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looked at whether waiting 60 seconds to clamp the umbilical cord (delayed cord clamping) raises bilirubin levels in newborns whose mothers had a previous child with jaundice needing treatment. Twenty mothers and their babies took part. The goal was to see if delayed clamping increases jaundice risk in these already at-risk infants.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If it works, this could help doctors decide the safest way to clamp the cord for babies at risk of jaundice.
What could go wrong
This is a very small, completed study with only 20 participants, so results may not apply to all babies. It only measures bilirubin levels, not long-term outcomes.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

20 people

The number who actually took part.

Finished

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 40 years

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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).
