Trial summary

In this study the investigators test the hypothesis that automated FiO2 adjustment increases the time of brain tissue oxygenation within the intended reference range. Furthermore, the investigators studied the change in workload during automated FiO2 adjustment as compared to manual adjustment by the nursing staff. Read more about this study

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 96 hours to 30 weeks
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • postmenstrual age <30 wks GA at study time
  • on nasal/nasopharyngeal CPAP or mechanical ventilation (including nasopharyngeal IMV)
  • at least 4 desaturations (SpO2 <80%) during an 8 hour period within the 24h before the study using a standard pulse oximeter incorporated in the NICU (Dash 3000, General Electric, Freiburg; 10s averaging time, delay 10s)

About this study

Official title: Effects of Automated Adjustment of Inspired Oxygen on Fluctuations of Regional Cerebral and Arterial Oxygenation in Preterm Infants With Frequent Desaturations

In this study the investigators test the hypothesis that automated FiO2 adjustment increases the time of brain tissue oxygenation within the intended reference range. Furthermore, the investigators studied the change in workload during automated FiO2 adjustment as compared to manual adjustment by the nursing staff.

Read the detailed description

Recorded data on brain tissue oxygenation will be compared with reference data obtained from other studies. Data from experimental mode (automated FiO2 control will be compared with manual FiO2 control).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Automated FiO2 ControlDevice

    Infants will be ventilated with or without automated FiO2-Control in a randomized sequence.

Study groups in NCT01942473
Study groupRoleWhat they receive
Automated FiO2 controlExperimentalInfants will be changed to a specific ventilator device approved for clinical use in neonates in Germany (Avea, Carefusion 234 GmbH Hoechberg, Germany), which is capable to automatically adjust the FiO2 based on readings of an incorporated SpO2 monitoring device. Infants will be allowed to adjust for at least 2h using the ventilator settings as chosen by the clinical team responsible. Thereafter, data will be recorded for 24h experimental time.
Receives: Device: Automated FiO2 Control
Manual AdjustmentPlacebo comparatorInfants will be exposed to the first study phase (clinical routine or automated FiO2 adjustment) for 24 h and then will be switched to the alternate mode (automated FiO2 adjustment or clinical routine) for another 24 h.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cerebral tissue oxygen saturation

    mean cerebral tissue oxygen saturation as well als distribution of cerebral tissue oxygen saturation over time will be assessed

    Measured: 48 hours

Secondary outcomes (3)
  1. number and mean duration of episodes with an SpO2 <80%, <75%, <70% and with hyperoxemia (SpO2 >96%)

    The number and mean duration of expisodes of desaturation and with hyperoxemia will be assessed

    Measured: 48 hours

  2. time within a defined target range of cerebral oxygen saturation (59% - 81%)

    time (as measured as the percentage of the total recording time) within a defined target range of cerebral oxygen saturation (59% - 81%) which corresponds to the 10th and 90th percentile obtained from a pilot study in 16 preterm infants with desaturations during the time when their SpO2 was aimed within the target range of a SpO2 of (88-96%).

    Measured: 48 hours

  3. workload for the medical staff related to number of adjustments of FiO2

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

A study of Preterm Infant and RDS, run by University of Ulm at 1 site in Germany.

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 8 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 26 Nov 2014. 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 Germany. 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. Some participants in this study may receive a placebo. 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?

Cerebral tissue oxygen saturation (time frame: 48 hours). 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 NCT01942473, 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 26 Nov 2014.
