Study of the ANI Validity on Evaluation of Nociception in State of Hypnosis

Regional University Hospital Center (CHRU)

Status: Completed

Conditions: Healthy

Treatments: Device: CO2 laser and ANI monitor

Study type: Interventional

Funder types: Other

Identifiers

NCT02302313

RB 13.186 ANI-HYPNOSE

Details and patient eligibility

About

Healthy subjects should assess pain on a numerical scale (EN), during painful skin stimuli of variable intensity delivered by a CO2 laser used at the power of 0.3 W, known for its safety. ANI (Analgesia Nociception Index) will be raised simultaneously. This sequence will be made on subjects at rest and in a state of hypnosis using the technique of "remembering a pleasant memory" and the ideo-sensory technique of "protective glove".

The average value of the ANI will be compared to the value of the EVN of pain intensity.

Description:

No drug and no placebo will be used in this study. The study participants will only rate their pain on a numerical scale (EN) following cutaneous painful stimulation (6 for each phase) of variable intensity, delivered by a CO2 laser. ANI (Analgesia Nociception Index) will be raised simultaneously by the ANI monitor. This sequence will be performed on subjects at rest and in a state of hypnosis by the technique of "remembering a pleasant memory" and the ideo-sensory technique of "protective glove".

Device: CO2 laser and ANI monitor
