Nutrition & Hydration/Persistent Vegetative State (PVS)

Full Answer Section

PN is typically delivered through a catheter inserted into a vein, most commonly in the chest or arm. The nutrient solution contains carbohydrates, proteins, fats, vitamins, minerals, and electrolytes. The specific composition of the solution is tailored to the individual's needs.

PN can be complete, providing all of a person's nutritional needs, or partial, supplementing an inadequate oral or enteral intake.

There are different types of PN, depending on the duration of use and the location of the catheter:

• Central line PN: This type of PN is used for long-term needs and is delivered through a catheter inserted into a large vein near the heart.
• Peripheral line PN: This type of PN is used for short-term needs and is delivered through a catheter inserted into a smaller vein in the arm or hand.
• Home parenteral nutrition (HPN): This type of PN allows people to receive PN at home, with proper training and support.

PN is a complex medical intervention that should only be administered under the supervision of a healthcare professional. There are potential risks associated with PN, such as infection, blood clots, and liver problems.
