About this study

Prospective study comparing hemodynamic and respiratory changes and exercise capacity during Cardio-Pulmonary-Exercise-Testing (CPET) in 4 groups of infants; Three different groups of premature infants and term controls

Read the detailed description

The study population included 4 groups of infants; preterm infants born < 300 weeks' gestation with BPD (i.e. oxygen dependence for at least 28 postnatal days 5), preterm infants born < 300 weeks' gestation without BPD, late preterm infants (born at 340-366 weeks' gestation) and term controls.

Pulmonary function testing and spirometry were measured Participants performed CPET on an electronically braked cycle ergometer. During the exercise testing, serial saturation, heart rate and blood pressure measurements were obtained.

The peak oxygen consumption (VO2max) was measured and served as the primary endpoint of the study.

Model description
Participants performed CPET on an electronically braked cycle ergometer . During the exercise testing, serial saturation, heart rate and blood pressure measurements were obtained. The peak oxygen consumption (VO2max) was measured and served as the primary endpoint of the study. A CPET technician and a senior pediatrician were present and monitored the participants' condition during the study.

Questions about this trial

What is this clinical trial studying?

A study testing Cardio-Pulmonary-Exercise-Testing (CPET) in people with The Peak Oxygen Consumption (VO2max) Was Measured and Served as the Primary Endpoint of the Study, run by Rambam Health Care Campus.

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 2 inclusion and 6 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 9 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

The peak oxygen consumption (VO2max) (time frame: During the 1 day test). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04833647, which also lists 1 linked publication.

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 9 Apr 2021.
