A 5-day-old preterm infant with a birth weight of 1.4 kg is now 10% below birth weight. The current serum sodium is 132 mEq/L and blood glucose values have ranged from 62–69 mg/dL over the past 24 hours. The infant is receiving TPN containing D11W at 7.5 mL/hr via a PICC line, providing 2 mEq/kg/day of sodium. A UAC infusing 1/2 normal saline at 1 mL/hr is being discontinued today. Which fluids provide the best sodium and glucose infusion rate (GIR) management for this infant?
