全靜脈營養（TPN）含有高濃度的葡萄糖、胺基酸與脂質，是細菌生長的理想培養基。由於 TPN 通常經由中央靜脈導管（Central Line）輸入，導管相關血流感染（CRBSI）風險極高，一旦感染可能導致敗血症。因此，在進行導管護理與換藥時，嚴格遵守無菌技術（Aseptic Technique）是預防併發症的首要關鍵。
TPN solutions are rich in nutrients that support rapid bacterial growth, making catheter-related bloodstream infections (CRBSI) a serious and potentially fatal complication. Consequently, using strict aseptic technique during all dressing changes and line manipulations is the most critical nursing intervention to prevent infection.
