Impact of malnutrition on the outcome of critically-ill children: A comprehensive narrative review

Malnutrition presents a universal challenge, affecting millions of children and resulting in severe health consequences. Notably, its consequences within the pediatric population, especially those that necessitate admission to the pediatric intensive care unit (PICU), are of concern. This narrative review discusses the nutritional status, particularly malnutrition, and factors associated that impact the outcome during the PICU stay. Furthermore, the interpretation of clinical conditions and physiological aspects and the understanding of potential interventions together help to analyze the outcome associated with malnutrition. By studying these aspects, this review proposes to contribute a proper understanding of how malnutrition closely influences outcomes in the condition of children admitted to PICUs.
