Values are expressed as mean (SEM).
↵2-150 For the paired t test, the analysis was based on the paired differences and only patients who had both sets of measurements contributed to the analysis.
NS, normal saline; D5W, isotonic dextrose; IAA, isotonic amino acids; TPN, total parenteral nutrition; D5 0.25% NS, 5% dextrose in 0.25% normal saline.
