What this trial studies

This study investigates the effectiveness of perioperative oral decontamination and immunonutrition supplementation in reducing postoperative complications among elderly patients undergoing elective non-cardiac surgeries. It is a prospective, single-center, randomized controlled trial that will recruit patients aged 65 and older, who will be divided into four groups to receive different combinations of oral care and nutrition interventions. The aim is to assess whether these interventions can improve patient outcomes and reduce the risk of complications related to surgery.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications in elderly patients, leading to better recovery and overall health outcomes.

How similar studies have gone: Other studies have shown promising results with similar interventions in improving postoperative outcomes, suggesting that this approach may be effective.
