Study summary

Hypnosis has already shown to decrease pain and anxiety in different surgical specialities. Nevertheless, its input has never been studied in cardiology. This research is a prospective, monocentric, controlled and randomized study.

Patients over 18 years old and hospitalized for atrial flutter ablation may be included and randomized into one of the arms: placebo or hypnosis.

Global pain will be assessed by a visual analogue pain scale. Anxiety, morphine consumption, and patient sedation will also be assessed.

The aim of this study is to improve the care given to patient undergoing atrial flutter ablation.

In context

Atrial Flutter

223 studies on the registry are indexed under Atrial Flutter; 51 are open to participants now.

This study's enrollment of 116 is below the median of 150 across 155 interventional studies indexed under Atrial Flutter.

Inclusion criteria

  • Over 18 years old
  • Surgery ablation of atrial flutter
  • Agreement to participate of the study

Exclusion criteria

Exclusion Criteria:

  • Person who does not speak French or deaf
  • Chronic pain with the visual analogue scale > 5
  • Psychiatric pathology
  • to paracetamol, lidocaine, morphine
  • Pregnant women, or breast-feeding women or without effective
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Study arms

  • Placebo comparator
    Placebo

    Placebo will be the suggestion of self-relaxation methods (for example, "try to relax" ,"try to think of pleasant moment ") and the diffusion of "white noise" during surgery.

    Other: Placebo

  • Experimental
    Hypnosis

    Hypnosis will be associated with the usual anesthesia. Hypnosis is a temporary modification of consciousness technique based on suggestion. It is divided into three phases: * induction: attention of the patient fixed on an object or a part of the body, * the dissociation where the patient cuts off auditory, visual and tactile perceptions, * and finally the opening towards a hypnotic experience thanks to the imaginary.

    Other: Hypnosis

Interventions

  • OtherHypnosis

    Hypnosis will be supervised by a nurse trained by the French Institute of Hypnosis.

  • OtherPlacebo

    Placebo consists in non-hypnotic relaxation suggestions and in hearing white noise through headphones

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 Oct 2017 to primary completion in Sep 2019, 23 months.

Of 55 interventional studies with no phase under Atrial Flutter, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 63. This study's 23 months is below that.

How these figures are worked out, and which studies are left out of them.

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 Feb 10, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
