Using micro/nanobubbles to heal acute and chronic wounds

Micro/Nanobubbles (MNBs) and Wound Therapy: A Pilot Study Involving a Novel Oxygen Delivery System for Treatment of Acute and Chronic Wounds

Early Phase 1 Interventional University of California, Irvine · NCT05169814

This study is testing if tiny bubbles can help heal both new and long-lasting wounds by improving oxygen delivery to the affected areas.

What this trial studies

This study evaluates the safety and effectiveness of micro/nanobubbles (MNBs) in promoting the healing of acute and chronic wounds. By enhancing oxygen delivery to the wound site, MNBs may improve healing outcomes. Participants will receive MNB treatment either through saline gauze for acute wounds or negative pressure wound therapy with instillation for chronic wounds. Wound characteristics will be assessed before and after treatment, with measurements taken to analyze the impact of MNBs on healing.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with traumatic, surgical, or chronic wounds, as well as specific types of ulcers and burn injuries.

Not a fit: Patients with infected wounds or those with wounds involving vital structures or malignancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly enhance wound healing for patients with various types of wounds.

How similar studies have performed: While the use of MNBs is a novel approach, similar studies have shown promise in enhancing oxygen delivery for wound healing.
