A Single Mindfulness Meditation Session in Preoperative Anxiety : Effects on the Autonomous Nervous System

An interventional study of relaxation session in Anxiety and Relaxation, sponsored by Centre Hospitalier Universitaire de Saint Etienne. Completed at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-05-17.

Study summary

Anxiety is an emotional disorder. It's a painful concern caused by uncertainty. It is a complex phenomenon misunderstood in spite of medical progress. Relaxation is a technical for reduce anxiety and is effective and safe. Previous study demonstrated the impact of session relaxation on the autonomous nervous system by the heart rate variability.

Primary objective of this new study is to demonstrate a link between heart rate variability and reduced anxiety during relaxation session.

Read the detailed description

It is monocentric, prospective and interventional study. This study will be proposed at the patients who will have an orthopedic surgery in full hospitalization. These patients are anxious because of surgery too. The day before surgery anesthetist save heart rate variability and value of the partial pressure of carbon dioxide during relaxation session.

    Patients anxious will be perform relaxation session.

Interventions

  • Otherrelaxation session

    During relaxation session, patients anxious will have three electrodes for save heart rate variability and a sensor for save value of the partial pressure of carbon dioxide. Before and after relaxation session, patient evaluates his anxiety by visual analogue scale (VAS) and State-Trait Anxiety Inventory (STAI-Y).

What researchers measure

Primary outcomes

  1. high frequency

    from the variation of heart rate. Measured by electrocardiogram.

    Time frame: continuously during the relaxation session

Secondary outcomes

  1. anxiety

    Measured with the State-Trait Anxiety Inventory (STAI-Y) Interpretation : Very high:\> to 65 High: from 56 to 65 Average: from 46 to 55 Low: from 36 to 45 Very low: \<or = 35

    Time frame: after the relaxation session at day 1

  2. low frequency

    Measured by electrocardiogram.

    Time frame: continuously during the relaxation session

  3. the ratio of high frequencies to low frequencies

    Measured by electrocardiogram.

    Time frame: continuously during the relaxation session

  4. PetCO2

    measured with a sensor fixed in front of the nostril

    Time frame: continuously during the relaxation session

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Sep 2018, 10 months.

Of 3,841 non-industry interventional studies with no phase under Anxiety Disorders, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's 10 months is below that.

Counting every sponsor, half of 3,943 studies reached it within 12 months; a quarter within 5 and three quarters within 28.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 17, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
