Prediction of Jaundice in Term Infants

March 20, 2019 updated by: NICHD Neonatal Research Network

BilirubinProduction in Healthy Term Infants as Measured by Carbon Monoxide in Breath

The objective of this study was to describe total bilirubin production in healthy term infants as a means of understanding the differences in jaundice pigment production associated with various common clinical circumstances.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Jaundice occurs in most human neonates during the several days after birth. The objective of this study was to describe total bilirubin production in healthy term infants as a means of understanding the differences in jaundice pigment production associated with various common clinical circumstances.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 8 hours (Child)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Term infants.

Description

Inclusion Criteria:

  • Infants born via cesarean delivery (to ensure subjects would still be hospitalized and available for ETCOc measurement and blood sampling on day 3 postpartum)
  • Delivery within each center's scheduled recruitment period (to maximize nursing availability and minimize cost)
  • Birth weight >2500 g
  • Gestational age >37 weeks

Exclusion Criteria:

  • Any illness that would require admission to the neonatal intensive-care unit (NICU) within 8 hours of birth

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
End-tidal carbon End-tidal carbon monoxide levels corrected for ambient air (ETCOc)
Time Frame: 2-8 hours of age
An index of bilirubin production
2-8 hours of age

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 1991

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
November 1, 1992

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
