In this second surgery tutorial on Surgical Nutrition we're going to talk about TPN as fluid and energy. This is absolutely essential to understanding TPN. I always tell the medical students and residents when you think about TPN, think of it of a bag of fluid and energy. How much fluid does your patient need? How much energy do they need?

Definitely check out the first video if you haven't watched that yet and the metabolic response to injury videos as they are key to understanding surgical nutrition and TPN...absolute prerequisites.
