Brief Summary:
Loss of muscle mass is a major cause of intensive care unit-acquired weakness (ICU-AW) and is associated with delayed weaning; prolonged ICU and hospital stay and is an independent predictor of one year mortality.
Theoretically, the best strategy to minimize muscle loss during ICU stay, is delivering an appropriate nutritional support. Studying the correlation between the sequential assessments of quadriceps femoris muscle layer thickness (QMLT) by the aid of Ultrasound in addition to the traditional method (NB) for assessment of nutritional status may be helpful to predict outcome and mortality.

Detailed Description:
Protein catabolism and proteolysis, mainly in the skeletal muscles is highly accelerated in critical illness with severe acute inflammatory processes, such as sepsis, burns, and polytrauma patients. The resulting catabolic state may be linked to immunosuppression, poor wound healing, and intensive care unit-acquired weakness (ICU-AW), which are associated with delayed recovery and increased mortality. In order to prevent muscle-protein depletion, several strategies have been proposed. One of them is adequate nutrition. Higher protein intake appears to be beneficial and could mitigate the negative catabolic state by increasing the availability of exogenous amino acids.
The adequacy of protein intake could only be optimized by appropriate monitoring. Nitrogen balance (NB) is the commonly used tool in this context. It is considered a good marker of adequate protein intake, easy, and available method of assessing the success of nutritional therapy as it reflects the gain or loss of total body proteins by calculating the difference between dietary nitrogen intake and nitrogen losses.
Moreover, a considerable reduction in muscle mass begins within the first 3 days of ICU admission and progressively worsens; therefore quantifying the muscle size may help in recognizing patients at risk of ICU acquired weakness and also may guide the interventions to prevent this complication. So, it may help in monitoring the adequacy of nutritional therapy and protein intake.
The primary methods that have been explored to measure musculature include computed tomography (C.T), magnetic resonance imagining (MRI), ultrasonography (US), and bioimpedance. Ultrasonography as a noninvasive, practical, readily available, and bedside technique could be considered the first option for the quantification of muscle size in these patients.
The quadriceps muscle is the most studied muscle found to have strong correlation with muscle mass and strength. Its size can be measured by either the quadriceps muscle layer thickness (QMLT) or the cross-sectional area (CSA). However, QMLT have greater practicability as measurements could be obtained rapidly and in real time as well as it easier to identify than CSA.
Since, monitoring is the key to individualize and optimize the critical protein intake. We hypothesized that QMLT evaluation by ultrasound could be used to guide nutritional protein intake and is correlated to conventional monitoring with nitrogen balance in critically ill trauma patients.
