Using Prontosan to treat bacterial biofilm in chronic wounds

Effectiveness and Safety of Using Prontosan Wound Irrigation Solution to Treat Bacterial Biofilm in Chronic Wound Patients With Secondary Infections: a Randomized, Controlled, Open Multicenter Study.

Not applicable Interventional The First Hospital of Jilin University · NCT06185465

This study is testing if Prontosan, a special wound cleaning solution, can better remove harmful bacteria from chronic wounds like diabetic foot ulcers compared to regular salt water.

What this trial studies

This clinical trial evaluates the effectiveness and safety of Prontosan wound irrigation solution compared to Normal Saline in removing bacterial biofilm in patients with chronic wounds, such as diabetic foot ulcers and pressure injuries. It is a prospective, multi-center, randomized, parallel-controlled, open-label study that aims to measure the positive detection rate of bacterial biofilm before and after treatment. The study will assess the morphological characteristics of the biofilm and its development over time in response to the treatments.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with chronic wounds, such as burns or diabetic foot ulcers, that show signs of bacterial infection and biofilm formation.

Not a fit: Patients with early-stage pressure injuries or those who have received systemic antibiotics within 48 hours prior to enrollment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve healing outcomes for patients with chronic wounds affected by bacterial biofilm.

How similar studies have performed: Other studies have shown promising results using similar approaches to treat bacterial biofilm in chronic wounds, indicating potential for success.
