Total parenteral nutrition (Part 1).
If administered safely and effectively, total parenteral nutrition (TPN) can be a life-saving intervention for many patients. Where skill, knowledge or due care are lacking, however, it can be life-threatening. So what is TPN, and why is it still viewed somewhat sceptically by certain members of the medical profession? In two articles, the author aims to answer these questions. Next week, she looks at the metabolic, pharmacological, mechanical, infection-control and psychological issues that influence the administration of TPN. In this article, she describes TPN's controversial history and outlines the essential principles of safe practice.
