Analysis of Current Use of Early Parenteral Nutrition and Clinical Significance of Non-protein Calorie: Nitrogen in Surgical Critically Ill Patients

Abstract

Surgical critically ill patients require adequate nutrition support and the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) guidelines recommend low non-protein calorie:nitrogen ratio (NPC:N ratio, 70∼100) for critically ill pateints. In this study, we assess the current use of early parenteral nutrition of surgical critically ill patients and analyze the clinical significance of NPC:N.
