Leucine-enriched Branched-chain Amino Acid on Muscle Thickness, Interleukin-6, SOFA Score in Critical Illness

The goal of this clinical trial study is to test effects of leucine-enriched branched-chain amino acid (BCAA) in critically ill patients. The main questions it aims to answer are: • How are the changes in muscle thickness between groups at baseline and end of study • Is there a decrease in interleukin-6 levels between groups at baseline and end of study • Is there a decrease in sequential organ failure assessment score between groups at baseline and end of study. Participants will be given leucine-enriched branched-chain amino acid 40 g/day enterally or parenterally for 10 days. Researchers will compare with control groups to see if there is any changes between groups at baseline and end of study. Both groups will be given standard nutrition with target energy of 20 kcal/kg bodyweight(BW)/day and ratio of nitrogen:non-protein calorie 1:70 and neuromuscular electrical stimulation 30 minutes per day.
