Diarrhoea in the Enterally Fed Critically ILL Patients: A Literature Review

Abstract

Diarrhea is a complication in critically ill patients, contributing to increased morbidity and healthcare costs. It is often multifactorial in origin, arising from infections, enteral nutrition, medications (especially antibiotics), and altered immunity and gastrointestinal function due to critical illness. Diarrhea in these patients can exacerbate fluid and electrolyte imbalances, increase the risk of skin breakdown, and contribute to malnutrition. Identifying the underlying etiology is essential for targeted management. Diagnostic approaches typically include stool cultures, assessments for Clostridium difficile infection, and evaluation of medication-related causes. Treatment involves supportive care, such as fluid and electrolyte replacement, modifying enteral nutrition, and judicious use of anti-diarrheal agents when appropriate. Preventative strategies, such as the careful use of antibiotics and probiotics, may reduce the incidence of diarrhea in critically ill patients. Addressing diarrhea effectively requires a multidisciplinary approach to reduce complications and improve patient outcomes in the critical care setting.
