Abstract

Parenteral nutrition (PN) is a critical intervention for surgical patients who cannot meet nutritional needs via the gastrointestinal tract. This article explores the principles of PN through the lens of When, How, and Why, providing evidence-based guidance for timing, administration, and monitoring. Emphasis is placed on optimizing outcomes, minimizing complications, and addressing ethical considerations in resource-limited settings.
