What this trial studies

This multicenter randomized controlled trial aims to evaluate the effectiveness of perioperative oral decontamination and immunonutrition supplementation in preventing postoperative pulmonary complications in elderly patients aged 65 and older undergoing elective non-cardiac surgeries. Participants will be randomly assigned to receive either immunonutrition supplements or routine nutrition advice, and oral chlorhexidine decontamination or routine oral care. The study will compare the incidence of postoperative pulmonary complications and other related outcomes between the intervention and control groups. The primary outcome will be assessed within 7 days post-surgery, with secondary outcomes including pneumonia incidence, functional recovery, and hospital stay duration.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients aged 65 and older who are scheduled for elective non-cardiac surgeries and assessed to be at intermediate to high risk for respiratory complications.

Not a fit: Patients undergoing emergency surgeries or those with pre-existing conditions that contraindicate the interventions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of postoperative pulmonary complications in elderly patients, improving their recovery and overall health outcomes.

How similar studies have performed: Other studies have shown promising results with similar approaches in reducing postoperative complications, suggesting that this study builds on established concepts.
