摘要

A 45-year-old man, weighing 50 kg, was admitted for intestinal perforation sepsis and acute respiratory distress syndrome (ARDS). After 10 days on the ventilator and antibiotics, he was weaned off the ventilator and started on parenteral nutrition (TPN) at 2500 kcal/day. The next day he developed difficulty in breathing, requiring reintubation and ventilator support. On investigation, S. Na 138 mEq/L, S. K 2.1 mEq/L, S. Cl 98 mEq/L, S. Ca (total) 7.2 mg/dL, S. phosphorus 0.7 mg/dL, S. Mg 1.1 mg/dL, pH 7.30, PCO2 56 mmHg, and HCO3 23 mEq/L.
