Parenteral nutrition (PN) is widely utilized in the field of neonatology and is a critical life-saving intervention for critically ill neonates or preterm infants who cannot meet their energy and nutrient needs through enteral feeding. To further standardize and optimize the clinical management of PN, this consensus was developed by a working group based on relevant research progress both domestically and internationally. Employing the Grading of Recommendations Assessment, Development and Evaluation, the consensus presents 24 recommendations covering seven aspects of PN: indications, administration routes, energy, fluid volume, composition of nutritional solutions, timing of cessation, and monitoring. The aim is to provide guidance for relevant practitioners in PN management to improve the short-term and long-term outcomes for neonates.
