Official Title: Diaphragm Function in Patients Acquired Weakness and Neuromyopathy in ICU: Impact on Weaning and Outcome (DIAPH-WEAK ICU)
Brief Summary:
Critical illness neuromyopathy is a common disease acquired during ICU stay leading to a deep weakness involving the respiratory muscle work which result in a delayed weaning of mechanical ventilation.
The main objective is to quantify the loss of diaphragm function by measuring the diaphragm force (using the non invasive method by phrenic nerve stimulation allowing to measure the twitch airway pressure during airway occlusion) in a selected population of patients with critical illness neuromyopathy (defined as a MRC score < 48).
The second end points are to evaluate its incidence, the consequences on the patients outcome (extubation success or failure; ICU stay) and to evaluate the relations between diaphragm function (twitch airway pressure during airway occlusion, maximal inspiratory pressure and diaphragm thickness evaluated by ultrasound) and peripheral limbs force (evaluated by the Medical Research Council - MRC score).
