Early Enteral Feeding and Clinical Outcomes in ICU Patients

Early enteral nutrition was initiated within 24-48 hours of ICU admission based on a structured protocol aligned with ASPEN and ESPEN guidelines. The protocol defined target caloric goals, methods of tube feeding initiation, rate advancement, and monitoring procedures. Nurses and ICU staff were trained in protocol implementation. The goal was to optimize nutrition early in critical illness to improve clinical outcomes such as ICU length of stay, ventilator dependence, and physiological stability.

Patients in the control group received standard nutritional care per routine hospital practices. Initiation and progression of feeding were left to the discretion of the attending physician and nursing staff, without the use of a structured protocol or defined early feeding timeline.
