Skeletal Muscle: A Critical Organ for Survival and Recovery in Critical Illness.

The intensive care unit (ICU) environment is one of the most challenging for skeletal muscle health. Atrophy associated with clinical care is distinct from that seen with inactivity or immobilization in the absence of disease and is exacerbated by aging. The substantial muscle loss in the ICU is likely due to the presence of inflammation, elevated proteolysis, bedrest, and undernutrition. Skeletal muscle parameters at admission are predictive of mortality and other clinically important outcomes. Treatment goals to mitigate muscle loss are early mobilization and adequate nutrient supply, especially protein, using an individualized approach to support skeletal muscle maintenance and recovery.
