Nutritional support for critically ill patients by the Korean Society for Parenteral and Enteral Nutrition—part II: a clinical practice guideline: Jae Gil Lee, You Min Sohn, Seung Hwan Lee, Yun Tae Jung, Hak-Jae Lee, Jeong Yun Park, Nak-Jun Choi, Jung Mi Song, Jee Young Lee, Ji Yeon Kim, Ji Yeong Jeong, Ye Won Sung, Eun Jeong Park, Hyun Ji Ko, Ji Yoon Cho, Bomi Kim, Yesung Oh, In Chung Lee, Jin Young Lee, A Ram Kim, Jee Yeon Lee, Seong-Eun Kim, Tae Sun Ha, Min Kwan Kwon; Ann Clin Nutr Metab 2026;18(2):65-116.

Abstract PDF Supplementary Material: Purpose
Nutritional therapy is an essential component of intensive care management. Appropriate nutritional support may reduce infectious and metabolic complications and promote recovery in critically ill patients. However, nutritional practices vary across institutions, and international guidelines may not be directly applicable to clinical practice in Korea. Evidence-based clinical practice guidelines that reflect Korean intensive care unit practice are therefore needed.
Methods
The Korean Society for Parenteral and Enteral Nutrition developed these clinical practice guidelines for nutritional therapy in critically ill adults through a systematic literature review and multidisciplinary expert consensus.
Results
In total, 24 key clinical questions and 59 recommendations were developed. The guidelines address enteral and parenteral nutrition, feeding intolerance, aspiration prevention, energy and protein assessment, immune-modulating nutrition, micronutrient supplementation, refeeding syndrome, and disease-specific nutritional therapy for critically ill adults, including those with acute kidney injury, acute liver failure, acute respiratory distress syndrome, sepsis, trauma, and obesity. The recommendations emphasize individualized nutritional therapy according to hemodynamic status, metabolic phase, organ dysfunction, nutritional risk, and treatment goals.
Conclusion
These guidelines provide practical, evidence-based recommendations for nutritional therapy in critically ill adults and reflect both current international evidence and Korean clinical practice. They may support more standardized and consistent nutritional support in Korean intensive care units.

Comparison of a volume-based feeding protocol with standard feeding for trauma patients in intensive care units in Korea: a retrospective cohort study: Juhong Park, Yesung Oh, Songhee Kwon, Ji-hyun Lee, Mihyang Kim, Kyungjin Hwang, Donghwan Choi, Junsik Kwon; Ann Clin Nutr Metab 2023;15(1):22-29.

Purpose: Although early enteral nutrition for critically ill patients is essential, it is difficult to provide enteral nutrition to trauma patients in early hospitalization stages due to frequent surgeries and examinations. We aimed to identify the effect of achieving early enteral nutrition goals and improving outcomes through a volume-based feeding (VBF) protocol for trauma patients.
Methods: Patients who were admitted to the trauma intensive care units (TICUs) of the Ajou University Hospital from January 2020 to September 2021 and received enteral tube feeding for at least 7 days were studied. An institution-specific VBF protocol was developed, and nurses were trained in its execution. We retrospectively compared outcomes, such as in-hospital mortality and initial nutritional goal achievement, between the new and standard protocols.
Results: Among 2,935 patients, 109 met the inclusion criteria. Of these, 64 patients received nutrition through VBF, with no feeding intolerance symptoms. The VBF group started enteral nutrition approximately 16.9 hours earlier and group achieved 80% of the target calorie and protein intake approximately one day faster than the control group (n=45). The average calorie supply per body weight per day was 4.9 kcal/kg/day more in the VBF group. An increase of 0.2 g/kg/day was also observed in protein uptake. However, mortality and adverse hospital events did not differ between the groups.
Conclusion: The VBF protocol for patients admitted to the TICU increased the initial nutrient supply without risk of feeding intolerance, but there was no improvement in major clinical outcomes, including mortality and adverse hospital events.
