Non-medicinal Technique and Dyspnea in Weaning Patients

Официальное название

Impact of a Non-medicinal Technique Medical Hypnosis on Perceived Dyspnea in Difficult Ventilatory Weaning Patients: a Multicenter Randomized Controlled Trial.

Обзор

This is a randomized, controlled, multicenter, open-label, category 2, parallel-arm study of efficacy and superiority. The target population are patients hospitalized in the intensive care unit (ICU), ventilated with invasive mechanical ventilation for 24 hours or more and having failed a spontaneous breathing trial (SBT, i.e. weaning test of invasive mechanical ventilation \[IMV\]). The primary objective is to evaluate the efficacy of medical hypnosis in reducing dyspnea experienced before the SBT in patients identified as difficult to wean in the ICU, compared with the protocolized standard of care. The primary outcome is the mean value of the daily visual analog scale (VAS) of dyspnea, self-assessed by the patient, measured immediately after the hypnosis session (before SBT) from Day-0 to Day-7 or until extubation. In the control group, the daily value (from D0 to D7 or extubation) of the self-assessed dyspnea VAS will be measured immediately before SBT. The protocol will be divided into two arms: a control arm in which standard of care practices regarding the daily SBT will be protocolized, and an interventional arm in which patients will receive protocolized medical hypnosis before the daily SBT in addition to the protocolized standard of care. The intervention (hypnosis or control) will be performed daily for 7 days (or until extubation, if applicable). The primary outcome will be assessed daily over the same period.

Вмешательства

• Поведенческое Protocolized medical hypnosis
  Patients who will receive protocolized medical hypnosis before the SBT every day between inclusion and day 7. Medical hypnosis sessions will consist in the administration of a 5-min hypnotic text by a loudspeaker installed in the ICU room, after selection of a hypnotic theme (sea, mountain or animals) by the participant. The hypnosis session will involve an induction phase, a suggestion phase and an emergence phase, along with self-hypnosis tips. The hypnosis session will immediately precede the
• Поведенческое Protocolized standard of care
  The protocolized standard of care will consist in the description of authorized human/behavioral patient-nurse interactions and patient installation prior to the daily SBT.

Первичные конечные точки

• Mean value of self-reported daily visual analog scale of dyspnea after the intervention or the control strategy [Срок оценки: Immediately after the hypnosis session (before SBT) from day 0 to day 7 or until extubation. In the control group, the daily value (from day 0 to day 7 or extubation) of self-reported VAS of dyspnea will be measured immediately before SBT.]

Вторичные конечные точки (12)

• Mean MV-RDOS score (Mechanical Ventilation-Respiratory Distress Observation Scale) after the intervention or the control strategy [Срок оценки: Immediately after the hypnosis session (before SBT) from day 0 to day 7 or until extubation. In the control group, the daily value (from day 0 to day 7 or extubation) of MV-RDOS will be measured immediately before SBT.]
• Mean VAS of dyspnea at the end of the SBT [Срок оценки: Immediately at the end of the daily protocolized SBT, which is performed every day from day 0 to day 7 or until extubation in all patients. Measured daily at the end of the SBT, from day 0 to day 7 or until extubation. Up to 28 days]
• Mean MV-RDOS at the end of SBT [Срок оценки: Immediately at the end of the daily protocolized SBT, which is performed every day from day 0 to day 7 or until extubation in all patients.]
• Mean VAS of anxiety at the end of SBT [Срок оценки: Immediately at the end of the daily protocolized SBT, which is performed every day from day 0 to day 7 or until extubation in all patients.]
• Mean VAS of pain at the end of SBT [Срок оценки: Immediately at the end of the daily protocolized SBT, which is performed every day from Day 0 to Day 7 or until extubation in all patients. The outcome measure consists in the mean value of the daily measures collected during this period.]
• Respiratory physiology [Срок оценки: Value of respiratory rate and SpO2, measured immediately at the beginning of the SBT, and worst value observed during the daily SBT, between inclusion and day 7 or extubation]
• Hemodynamic status [Срок оценки: Value of heart rate and mean arterial pressure, measured immediately at the beginning of the SBT, and worst value observed during the daily SBT, between inclusion and day 7 or extubation]
• Quality of applied intervention and control strategies [Срок оценки: Up to Day 7]
• Feasibility: enrolment [Срок оценки: At the end of the study recruitment.]
• Feasibility: hypnosis training [Срок оценки: At the end of the recruitment.]
• Safety: neurological impact of strategies [Срок оценки: The RASS value will be assessed continuously during the duration of the intervention in Gp1 or during the protocolized observation period in Gp2, and its highest value will be reported. It will be reported daily in each group, between inclusion and D7.]
• Invasive mechanical ventilation weaning [Срок оценки: Measured at day 28]
