Assessment of Muscle Wasting in Long-Stay ICU Patients Using a New Ultrasound Protocol

Abstract: There is currently no standardized procedure to assess sarcopenia in long-stay catabolic patients. Our aim is to analyze a novel ultrasound muscle assessment protocol in these patients versus healthy controls, by carrying out a prospective observational study. We designed a new ultrasound protocol that assesses quadriceps rectus femoris (QRF) muscle quality in real-time B-mode, color-Doppler, and M-mode ultrasound, and evaluates QRF intramuscular central tendon thickness, cross-sectional area, and muscle thick… Show more

“…If patients with sarcopenia are orientated and cooperated enough related to age and disease status, muscle strength and physical performance can be evaluated. As in our patient, central nervous system disease and prolonged respiratory support without sedation and weakness can be considered as indicators of low muscle strength and low physical performance (5,13). Imaging methods used to measure muscle mass are ultrasound (US), MRI, CT, DXA, and BIA.…”

“…In addition, it may not be possible to prevent muscle loss due to increased catabolism in the first period. Although proper protein intake and exercise have been used successfully to treat weakness in older patients (primary sarcopenia), it is possible to fail in severe catabolic status as in our patient, even if standard treatment is applied in sarcopenia due to secondary conditions (5,13). Studies on sarcopenia in patients admitted to the ICU are lacking.…”

“…These include imaging modalities that can be performed at the bedside using portable technologies and include ultrasound evaluation of skeletal muscle thickness [100] or fat-free mass [101] and CT evaluation of paravertebral or limb fat to muscle ratio [56]. For instance, a well-designed ultrasound protocol allows clinicians to assess quantitative and qualitative changes in the skeletal muscle in mechanically ventilated patients [102]. The results of ongoing clinical trials evaluating the effect of protein nutrition and/or exercise on functional recovery in the critically ill are pending (e.g., EFFORT sub-study, NEXIS [27,103]).…”
