Excerpt
Intensive care unit (ICU)-acquired weakness is a muscular weakness without other cause after intensive care and consisting of critical illness polyneuropathy and critical illness myopathy (CIM) [
1]. Muscle atrophy can occur quite early during critical illness because of increased muscle protein breakdown (MPB) and decreased muscle protein synthesis (MPS) [
1]. Although muscle mass can be evaluated using ultrasound [
2] and computed tomography (CT) [
3], MPS and MPB are difficult to evaluate separately. Muscle biopsy can directly evaluate MPB in CIM directly [
4], but it is invasive. Creatine kinase cannot evaluate MPB in CIM [
1]. Therefore, no noninvasive technique has been established. …
