Word parts
What it means
A sterile mixture of glucose, amino acids, fats, vitamins and minerals that gives the body everything it needs when the gut cannot be used. Because it is strong, it is usually given through a central line. It is used when a client cannot eat or absorb food for a long time, for example after major bowel surgery or with severe pancreatitis.
For the nurse
Check the blood glucose as ordered, since it can run high; run it on a pump at the set rate and never speed it up to catch up. If a bag runs out, hang 10% dextrose as ordered, because stopping suddenly can drop the blood sugar. The line needs strict aseptic care because it is a route for infection.
