Muscle wasting in intensive care patients: ultrasound observation of the M. quadriceps femoris muscle layer.
OBJECTIVE Patients in intensive care exhibit a high degree of loss of muscle mass . Appropriate instruments are needed to document muscle wasting in these patients . The aim of this pilot study was to describe muscle wasting in patients in the intensive care unit . DESIGN Two-fold study setting : prospect i ve longitudinal and cross-sectional single-blind . PATIENTS A total of 118 patients in the intensive care unit ( length of stay 1 - 98 days ; male : female ratio 88:30 ; age 55 + /- 17 years ) were included in a two-fold study setting . METHODS Muscle layer thickness of the M. quadriceps femoris was documented using ultrasound measurement at well-defined points . Seventeen pilot- patients were measured twice ; at baseline and after 28 days . In another group of 101 patients , muscle layer thickness was determined once after a r and om length of stay . The results of both groups were compared and correlated . RESULTS In both groups , M. quadriceps femoris thickness showed a significant negative correlation with length of stay in the intensive care unit ( p < 0.01 ) . Furthermore , muscle wasting in intensive care patients could be described using a logarithmic function . CONCLUSION Loss of muscle mass shows a negative correlation with length of stay , and seems to be higher during the first 2 - 3 weeks of immobilization/intensive care unit stay . Ultrasound is a valid and practical measurement tool for documenting muscle mass ( e.g. muscle layer thickness ) as part of the daily routine at an intensive care unit
