| Background A lot of outcome predictive tools are already in use in critical care setting with different degrees of reliability aiming for possible prevention or minimization of bad outcome and better resource management. Some critical illness sequelae significantly affect patient’s outcome and currently not included in the in-use predictive scoring system. Muscle wasting/weakness is one of these sequelae, and it was found to be an independent risk factor of poor outcomes. Objective This study was conducted to evaluate the degree of muscle wasting estimated by ultrasonography during ICU stay as a predictor of mortality, successful weaning of mechanical ventilation, ICU stay and hospital stay. Patients and Methods A prospective observational study was conducted in critical care units in Ain Shams University Hospitals, Cairo, Egypt over a period of 12 months. Results Decrease in muscle measurements was found to correlated to mortality in ICU with cutoff points from area under the curve for right QMT, left QMT, right RFCSA, left RFCSA, IEDT and EEDT were supposed to be:>9.77,>15, >16.67, >12.5, >12.63, >12.5, respectively, with best specificity and positive predictive value was found in right RFCSA (95.45, 87.5, respectively) while best sensitivity and negative predictive value was found in left RFCSA (65.38, 82, respectively). Significant negative correlation between vasoactive agent free period and maximum daily reduction in RFCSA, QMT, EIDT, and EEDT ( value = 0.001). Conclusion Daily reduction of the RFCSA and to lesser extent the QMT has significant correlation to mortality, prolongation of mechanical ventilation days and reduction in the vasopressor free days but has a poor correlation to the ICU and hospital stay. Pneumonia and renal disease had significant correlation with the muscle mass reduction. The left RFCSA found to be comparable to SOFA score as mortality predictor. | ||||
