Abstract
AIM: Ultrasonographic assessment of muscle mass and its relation to patient outcome in a medical ICU. Method: This observational prospective study was conducted on 454 critically ill patients admitted at our medical ICU in the period from June 2016 to January 2018 aged 18 years or more. All patients were examined, weight, height, body mass index and mid upper arm circumference (MUAC) were estimated. Routine labs were done for all patients. APACHI II, SOFA and NUTRIC scores were calculated. SOFA score was calculated at 0, 48 and 96 hours. Muscle layer thickness (MLT) was assessed using ultrasonography in the anterior arm and thigh points with and without compression. Length of stay, duration on mechanical ventilation and mortality were calculated. Results: The mean of age is 51 years ±19, 60.8% female, Length of stay mean 9.1 ± 12.5 days, mortality rate 36.56%. Mean APACHE score 16.4 ± 7.2 and SOFA 0 5.3 ± 3.6, NUTRIC 3.7 ± 2.1. MLT especially in the anterior thigh without compression correlated negatively with mortality but not with duration of mechanical ventilation or length of ICU stay. Also there was correlation of MLT with anthropometric, laboratory measures and hand grip strength. Conclusion: Ultrasonography measured MLT is a reliable tool that can be used as an indicator of the nutritional status and is correlated negatively with the mortality in critically ill patients
