全靜脈營養（TPN）含有高濃度的葡萄糖與電解質。若輸液突然中斷，病人體內持續分泌的胰島素會導致反跳性低血糖（Rebound hypoglycemia）。因此，當下一袋 TPN 尚未送達時，護理師應懸掛與 TPN 濃度相近的葡萄糖液（如 D10W）以維持血糖恆定。選擇 D10W 是為了避免血糖驟降，且需密切監測血糖值。
Total parenteral nutrition contains high concentrations of glucose, and abrupt discontinuation can lead to rebound hypoglycemia due to continued insulin secretion. To maintain blood glucose levels while awaiting the next bag, the nurse should hang 10% dextrose in water (D10W) as a temporary substitute.
