Using nasal povidone-iodine to prevent infections after orthopedic surgery

Intranasal Povidone Iodine (PVI) to Prevent Staphylococcus Aureus Surgical Site Infections After Operative Procedures to Fix High-Energy Lower Extremity Fractures (POTENT Study)

Phase 4 Interventional University of Iowa · NCT05763602

This study is testing if putting povidone-iodine in the noses of patients having surgery for serious leg fractures can help prevent infections after the operation.

What this trial studies

This study aims to determine if applying povidone-iodine (PVI) to the noses of patients undergoing orthopedic fixation for high-energy lower extremity fractures can reduce the risk of surgical site infections (SSI), particularly those caused by Staphylococcus aureus. Patients will receive PVI treatment within 60 minutes before surgery and again approximately 12 hours post-surgery. The study will track patient outcomes for six months following their procedures, including any signs or treatments for SSI. Data will be collected from medical records and follow-up visits to assess the effectiveness of this intervention.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 undergoing surgical procedures for high-energy lower extremity fractures.

Not a fit: Patients not undergoing the specified orthopedic procedures or those with contraindications to povidone-iodine may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of surgical site infections in high-risk orthopedic patients.

How similar studies have performed: Previous studies have shown promise in using topical antiseptics to reduce infection rates, but this specific application of PVI in this context is novel.
