TPN加入Fat Emulsion可以減少靜脈炎和對靜脈的刺激,因為:1. Lower Osmolality: The addition of fat emulsion to TPN can decrease the overall osmolality of the TPN solution. Osmolality refers to the concentration of solutes in a solution, and solutions with higher osmolality can be more irritating to blood vessels and surrounding tissues. By lowering the osmolality, the fat emulsion can make the TPN solution less irritating to the veins, reducing the risk of phlebitis, which is inflammation of the vein.2. pH Stabilization: Fat emulsions contain phospholipids that can help stabilize the pH of the TP...
