What is TPN and when do we need it?

How much fluid does the body need?

What is Total Parenteral Nutrition (TPN) and why is it important?

What is the respiratory quotient? Why is it important and how do you calculate it?

MUST HAVE SURGERY BOOKS

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.

Very nice sir. It’s really helpful in understanding the chapter in the textbooks. Thankyou for making these videos. Please do more

Very well presented...as a surgery resident I know that fluid and energy requirements of a surgical pt.(pre and post-op) are the most underrated and overlooked things which if followed correctly can make a huge difference in management. 👍

Hey Dr. Pearson, thanks for making these videos, they are super helpful. I see you use evernote a lot. Could you discuss how you organize your notes regarding textbook readings, procedures, as well as clinical information you encounter in the day-to-day

TPN is severely damaging my baby niece's liver (pre-term baby with an adjusted age of 2 months). What can be adjusted to my TPN less taxing on her liver? Apparently the hospital has already tried Omega-van and Smof to no avail. Currently she cannot feed through the mouth. Any advise/insight would be appreciated.
