Comparison of Clinical Outcomes According to High-protein Provision in Critically Ill Patients After Abdominal Surgery

Protein malnutrition in critically ill patients is a global concern due to its association with prolonged hospital stays, and higher morbidity rates. Patients who undergo abdominal surgery are particularly vulnerable due to alterations in gastrointestinal function and prolonged fasting. Despite the significance of proper nutrition, the optimal target of protein supplementation remains controversial. The investigators aimed to evaluate the effects of high protein provision, targeting a protein intake of at least 1.5 g/kg/day for the first 3 days after abdominal surgery, on 6-month mortality.
