— Explanation · 中文詳解 —
全靜脈營養(TPN)含有高濃度的葡萄糖與營養成分,病人的胰臟已適應這種高糖環境而大量分泌胰島素。若TPN突然中斷,高胰島素水平會導致反彈性低血糖(Rebound hypoglycemia)。因此,護理師應立即給予含有葡萄糖的溶液(如D10W)以維持血中葡萄糖濃度,直到下一袋TPN送達,這是預防低血糖休克的生命安全措施。
Hanging 10% dextrose in water prevents rebound hypoglycemia caused by the abrupt cessation of high-glucose TPN. This immediate intervention maintains blood glucose levels while the insulin response normalizes, protecting the client from shock.
