Parenteral nutrition (PN) is a method of nutrition assistance that has the potential to save lives, but it should only be used on patients for whom enteral feeding is risky, ineffective, or has failed. Total parenteral nutrition (TPN) or peripheral parenteral nutrition (PPN) are two terms that are frequently used to describe this treatment, depending on which vein is utilized (PPN). Therefore, it is crucial to think carefully about who, when, and how this type of dietary support should be provided. A multidisciplinary nutrition team should start PN and closely manage it to reduce any potentially fatal consequences.

- The speaker wishes everyone a happy nutrition week, emphasizing the growing importance and research in the field of nutrition. The session will focus on the fundamentals of parental nutrition, suggesting a possible future session to discuss new advancements.
- Parental nutrition, meaning outside of digestion, involves delivering nutrition intravenously when the digestive tract cannot be used. It can be short-term, long-term, or supplemental, and is classified as central (CPN) or peripheral (PPN) based on the vein used.
- CPN is delivered through a central vein, allowing for higher concentrations of nutrients and calories, while PPN uses smaller peripheral veins and is usually temporary. Parental nutrition can be partial, supplementing other feeding methods, or total (TPN), providing complete nutrition when the digestive system is not functioning.
- TPN is used in conditions such as abdominal surgeries, chemotherapy, intestinal ischemia, and other gastrointestinal issues. While enteral feeding is preferred, TPN becomes necessary when the digestive system cannot be used.
- A comprehensive nutritional assessment is crucial for customizing parental nutrition, considering the patient's health conditions and lab reports. This assessment includes patient history, medical diagnosis, medication history, physical examination, and social/environmental aspects.
- Successful delivery of parental nutrition requires a dedicated team, proper vascular access, and careful consideration of the patient's history and individual circumstances. Factors such as the risk of thrombosis, vein damage, edema, allergies, and the osmolarity and pH of the solution must be taken into account when choosing the route for venous access.
