RESUMEN
Critical patients have a high incidence of malnutrition, which can lead to adverse outcomes such as infections and ICU-acquired weakness. Improving the nutritional status of critically ill patients is currently an important challenge. Parenteral nutrition (PN) is an important component of medical nutrition, but there is still much controversy over how to implement a reasonable and standardized PN for critically ill patients. To further standardize the PN strategy for critically ill patients, the Critical Care Medicine Branch of the Zhejiang Medical Association convened experts in the field of critical care medicine and formulated the Expert consensus on clinical practice of parenteral nutrition therapy for critically ill patients in China (2024). This consensus is based on the GRADE evidence quality grading standard, problem oriented, and summarizes evidence-based medicine evidence from multiple aspects such as PN timing, suitable population, nutritional plan, and ingredient ratio, providing professional suggestions for the standardization and implementation of PN in clinical nutrition practice.
