Brief summary
This study evaluates the effect of a transcutaneous electrical stimulation in critically ill patients compared to a sham electrical stimulation to decrease the incidence of diaphragm dysfunction before mechanical ventilation weaning.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diaphragm Thickening fraction | Once, At the start of the spontaneous breathing trial | Diaphragm ultrasound was conducted using a 4-12-MHz linear array transducer. Diaphragm thickness was measured at end-expiration (Tdi,ee) and end inspiration (Tdi,ei), and thickening fraction (TFdi) was calculated offline as (Tdi,ei-Tdi,ee)/Tdi,ee. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Diaphragm atrophy | Once a day under mechanical ventilation, throughout the study | Diaphragm thickeness is measured each day of the study until mechanical ventilation weaning |
| Inspiratory strength | Once, At the start of the spontaneous breathing trial | Maximal inspiratory pressure is measured via an electrical manometer with unidirectional valve |
| Cough strength | Once, At the start of the spontaneous breathing trial | Peak expiratory cough flow is measured with the ventilator |
| Proportion of patients successfully liberated from the ventilator | After 3 days of spontaneous breathing | Extubation failure is reported when a patient present a respiratory distress and need an tracheal intubation in the 48 hours past extubation |
