What percent of dextrose solution is appropriate for TPN solution? 20%?

I understand that you hang Dextrose 10% if there are any interuptions in running the TPN to prevent hypoglycemia. Also, should TPN be delivered into a large peripheral vein as opposed to centrally? If so, Why? Finally, TPN is meant for long term therapy, correct?

Thank you for helping. I just don't feel clear on the details of TPN.

A lot of these things depend on the individual patient. There are no "definitive answers" that are right for everybody.

Maybe you should start the conversation by giving a few specific examples or case situations that you didn't understand.

TPN is delivered through a central venous catheter to prevent irritation to peripheral veins. We were told that TPN is not meant for long-term therapy.

20% is too high. The vein will not tolerate that much. I wouldn't go more than 10%.

Thank you for your help. I continued to research it today and discovered that TPN can be given peripherally as long as it's only 10% dextrose so as not to irritate the vein. It sounds like it's usually given centrally though. Please correct me if I'm wrong = )~
