ICU Acquired Weakness, Quadriceps Muscle Atrophy
Conditions
Brief summary
ICU-Aw is highly prevalent (50%) among critically ill patients. Its diagnosis is usually delayed as it requires patients' awakening and collaboration to provide accurate measurement. This study aims to investigate the accuracy of an early ultrasound measurement of quadriceps shortening during neuromuscular electrical stimulation to diagnose future ICU-Aw in critically ill patients.
Interventions
NMES will be applied to the quadriceps muscle to generate muscle contraction. Ultrasound measurement of the quadriceps thickness will be provided during contraction and rest, and the shortening of the quadriceps muscle will be measured. A second measurement using Shear-wave elastography measurement will also be undertaken. The measures will be undertaken at day 1 of neuromuscular blockers liberation (if any) as well as at day 3 and day 7 for the patients that will still be received mechanical ventilation at that time.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| ICU-Aw diagnosis | In the 24 hours following extubation | Measured with the Medical Research Council score (scored 0 (minimum) to 60 (maximum); with a score \< 48 meaning ICU-acquired weakness) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Respiratory muscles strength | In the 30 minutes before extubation (during spontaneous breathing trial) | Maximal Inspiratory Pressure and Maximal Expiratory Pressure |
| Cough capacity | In the 30 minutes before extubation (during spontaneous breathing trial) | Peak Cough Flow |
| Extubation failure/success | Within 48 hours after extubation | Reintubation or death |
