Comparison of Clinical Outcomes According to High-protein Provision in

Status Not yet recruiting

Clinical Trial Summary

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.

Clinical Trial Description

During the acute phase of critical illness, patients experience metabolic and physiological changes that affects their nutrition status. One prominent feature is the activation of stress hormones and inflammatory mediators, which contribute to a negative nitrogen balance, increased gluconeogenesis, and accelerated muscle proteolysis. Among these patients, those who undergo abdominal surgery are particularly vulnerable to malnutrition as they experience alterations in the structural barrier of the gastrointestinal tract, impaired nutrient absorption, and prolonged fasting due to concerns such as the integrity of an anastomosis. Thus, appropriate protein provision should be prioritized for critically ill patients following abdominal surgery, and it should include adequate nutritional support to preserve lean body mass and organ function. Despite the importance of nutritional supply, the recommendations for protein vary according to different guidelines, and this is the same for surgical patients. Recent randomized controlled trials reported conflicting results with current guidelines, with some suggesting that higher protein dose administrations did not significantly impact clinical outcomes and may even worsen the outcomes for certain patient groups. Thus, the optimal protein provision target during the acute phase of critical illness, particularly for surgical patients, remains controversial. The investigators aimed to assess the effects of strict high protein provision between the high protein group (protein target supplemented with 1.5 g/kg/day) and the control group (protein target supplemented with less than 1.5 g/kg/day) using intravenous nutrient solution for the first 3 days after abdominal surgery. Additionally, the investigators investigated the appropriate target for protein provision in critically ill patients who undergo abdominal surgery. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
