Critical Illness Myopathy | ICU Acquired Neuromyopathy and Diaphragm Function
Critical Illness Myopathy research study
What is the primary objective of this study?
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).
Who is eligible to participate?
Inclusion Criteria: - MRC score <48 - ready for weaning from mechanical ventilation Exclusion Criteria: - previous history of neuromyopathy - impossibility to perform a magnetic stimulation - cervical spine injury - bihemispheric or brain stem lesion
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Critical Illness Myopathy
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Other:Non invasive phrenic nerve stimulationNon invasive phrenic nerve stimulation allowing to measure the twitch airway pressure during airway occlusion
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
