ABSTRACT
Parenteral nutrition (PN) is the delivery of nutrition directly into the venous system, bypassing the gastrointestinal tract. The science and application of PN have evolved such that PN has become a common life-saving therapy in children. It is widely used in neonates, older pediatric patients, and adults with impaired gut function. PN should be considered a high-risk medication with several components that require trained clinicians to carefully prescribe and monitor. It is best done under the supervision of a multidisciplinary nutrition support team that includes physicians, advanced-level providers, pharmacists, dietitians, and nurses. This chapter provides the necessary information to prescribe, calculate, and monitor pediatric patients receiving PN and manage potential PN-related complications.
