Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 with traumatic, surgical, or chronic wounds, as well as specific types of ulcers and burn injuries.
✕Probably not a fit
Patients with infected wounds or those with wounds involving vital structures or malignancy may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
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.
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 gone: While the use of MNBs is a novel approach, similar studies have shown promise in enhancing oxygen delivery for wound healing.
