Peritoneal dialysis solutions are often color-coded based on the dextrose concentration. Dextrose is used as the osmotically-active agent. As it is partially absorbed, patients with diabetes have to watch out for elevated blood sugars. In addition, diabetic patients with extremely elevated blood sugars (e.g., in DKA for instance) will have a decreased gradient for ultrafiltration so it is especially important to keep their blood glucose under control.
Anyways, it’s important to know the color codes since often the patients will know they take 2 green and 2 yellow bags but not know the dextrose concentrations.
Yellow = 1.5% dextrose
Green = 2.5% dextrose
Red = 4.25% dextrose
