Muscle wasting assessed by ultrasound versus scoring systems as early predictor of outcomes of intensive care unit stay in critically ill patients

Abstract

We have recruited 100 patients, after either incomplete data or dropouts; the study was done on 70 patients admitted to the ICU on random base. No disease related mortality had been correlated. Increased daily reduction of RFCSA had most significant correlation with mortality (P value = 0.001), death occurred within mean of 1.38 days from maximum daily reduction of the RFCSA. Cutoff points from the ROD 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, EEDT (P value = 0.001). Significant correlation between duration of mechanical ‎ventilation ‎and maximum daily reduction in RFCSA, QMT (P value = 0.001).
