Respiratory failure & ventilation
The effects of hypnosis and music intervention on comfort and anxiety during weaning from mechanical ventilation: A pilot study
Authors' conclusion
In this pilot study, a single session of either hypnosis or music intervention was demonstrated to effectively reduce anxiety and enhance comfort, in critically ill patients facing extended or challenging MV weaning.
Study context
- Population
- Critically ill patients with extended or challenging weaning from mechanical ventilation (MV)75 eligible
- Participants

- Outcome
- Patient comfort and anxiety levels (Visual Analog Scale (VAS))

Main finding
As reported in the abstract
Comfort and anxiety (VAS), before to after intervention
- Hypnosis: comfort increased from 4 [2-6] to 8 [7-9]
- p < 0.01
- Music intervention: comfort increased from 5 [4-6] to 7 [5-8]
- p < 0.01
- Hypnosis: anxiety decreased from 5 [5-7] to 3 [2-5]
- p < 0.01
- Music intervention: anxiety decreased from 6 [5-8] to 4 [3-6]
- p < 0.01
Observational data: associations, not effects.
Further findings
Respiratory rate
- Hypnosis: decreased from 28 [25-37] to 24 [23-35]
- P < 0.01
- Music intervention: unchanged
Heart rate
- Significant decline from baseline after both interventions, then reverted to initial values
MAP (mmHg)
- Hypnosis: elevation from 94 (86-110) to 99 (80-108) mmHg
- P = 0.01
- Music intervention: reduction from 87 (75-101) to 82 (74-88) mmHg
- P = 0.01
Cortisol (μg/L)
- Music intervention: decreased from 249 [175-291] to 207 [145-242] μg/L
- P = 0.02
- Hypnosis: unchanged
- Both p = 0.04
EEG power
- Both interventions: significant decrease in slow delta power and increase in theta and alpha power, indicative of a hypnosis-like state
