What happens if you abruptly stop TPN?
TPN is usually slowed or discontinued prior to anesthesia, primarily to avoid complications from excessive (hyperosmolarity) or rapid decrease (hypoglycemia) in infusion rates in the busy operative arena. That said, because abrupt discontinuance may lead to severe hypoglycemia, TPN must be turned down gradually.

Is TPN a formula?
The TPN formula is monitored by the Infusion Solutions team, including pharmacists, nurses, and dieticians. The formula can be adjusted as necessary based on lab markers and the progress of the disease state. The rate of TPN administration can also be changed under some circumstances.
Does TPN have to go through a central line?
What is TPN? In short, when the digestive tract is not functional, TPN is necessary for patients to maintain adequate nutrition. TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath.
What do you flush TPN line with?
- Open-ended catheters must be flushed with saline before starting TPN. They must be flushed with heparin and saline after stopping TPN.
- Closed-ended catheters must be flushed with saline before and after TPN.
Can you draw blood from a TPN line?
Because TPN is lipid-rich and tends to stick to catheters, collection of blood specimens from the same lumen of a catheter used to administer the solution is best avoided.
