About this study

The purpose of this study is to evaluate the effect of vanilla odor on hypoxic intermittent events in premature infants born between 32.0 and 33.6 weeks of gestational age.

Read the detailed description

A weekly screening will be done on all new hospitalized infants at the neonatal care unit of the CHUS born between 32.0 and 33.6 weeks of gestational age. At the beginning of their 2nd week in the neonatal care unit, infant's medical record will be consulted for inclusion and exclusion criteria. At this moment, no information will be noted. Then, team research will discuss with neonatologist to have their opinion concerning the inclusion of a patient in the study. If they agree, the doctor or the nurse having a therapeutic link with the infant will ask parents' infant if they agree to meet the research team to discuss about the research project. Once the agreement will be obtained, parents will be approached by a member of the research team. Project will be explained, questions will be answered and consent form will be obtained. When an infant will be enrolled in the study, a code will be attributed to him and a randomization will established the order of the intervention.

Option A) night 1: a 12h cardiorespiratory recording with vanilla, night 2: no recording and night 3: a 12h cardiorespiratory recording without vanilla OR Option B): night 1: a 12h cardiorespiratory recording without vanilla, night 2: no recording and night 3: a 12h cardiorespiratory recording recording with vanilla.

All data will be entered in a secured database and a double checked will be done by team members to assess the accuracy.

What participants receive

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

  • Vanilla scentOther

    A 12-hour continuous recording for monitoring hemoglobin oxygen saturation, electrocardiogram and respiratory movements will be performed while the infant is exposed to vanilla scent (from vanilla solution on the infant's pyjamas).

Study groups in NCT02630147
Study groupRoleWhat they receive
Vanilla, Then no vanilla nightExperimentalParticipants were exposed to vanilla odor (2 mL of 2% vanillin on the bib, close to the face) on the first night (12-hour recording), and not exposed to vanilla on the third night (control night,12-hour recording) No intervention, no recordings were made on the second night
Receives: Other: Vanilla scent
No vanilla, Then vanilla nightExperimentalParticipants were exposed to the "control" condition on the first night, which consisted of no vanilla odor (12-hour recording), and then exposed to vanilla odor on the third night (2 mL of 2% vanillin on the bib, close to the face;12-hour recording) No intervention, no recordings were made on the second night
Receives: Other: Vanilla scent

What is being measured

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

  1. Desaturation Index

    Number per hour of oxygen saturation < 90% for at least 5 seconds

    Measured: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor

Secondary outcomes (4)
  1. Percentage of Time of Oxygen Saturation Under 90%

    Percentage time in overall duration of oxygen saturation under 90%

    Measured: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor

  2. Percentage of Time of Periodic Breathing

    Percent of time of the recording spent in periodic breathing or in apnea.

    A periodic beathing epoch was defined as a series of 3 episodes or more of apneas lasting at least 3 seconds and separated by less than 20 seconds of normal breathing

    Apneas were defined as the absence of respiratory movements for at least 20 seconds or for at least 2 breathing cycles with a decrease of at least 3% in SpO2

    Measured: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor

  3. Time in Apnea

    Percent of time of the recording spent in apnea

    Measured: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor

  4. Mean SpO2

    Mean value of oxygen saturation (%)

    Measured: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor

Questions about this trial

What is this clinical trial studying?

A study testing Vanilla scent in people with Premature Birth and Neonatal Hypoxic Conditions, run by Université de Sherbrooke at 1 site in Canada.

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 5 inclusion and 5 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 17 Jul 2023. 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 Canada. 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?

Yes. Results are posted in the registry (first posted 17 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Desaturation Index (time frame: 12 hour period of recording on the night 1 and 3 of each participants, in which they are exposed to vanilla or no vanilla odor). 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 NCT02630147, which also lists 2 linked publications.

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 17 Jul 2023.
