Fighting Biofilm in chronic wounds: Debridement and antimicrobial dressing VS Debridement and Qoustic Wound Therapy with sensitivity proved antibiotic solution

The challenge was to decrease and slow down biofilm formation on patient with chronic wounds to promote wound healing and avoid systemic treatment of wound infection.

Chronic wound patients with multiple co-morbidities being followed by outpatient wound clinic for months. Commonly developing wound infection requiring systemic antibiotic treatment, which contributes to developing of antibiotic resistance and not completely resolve a problem of wound healing due to biofilm formation. Debridement is proven way to disrupt biofilm, but needs to be performed every 48 hours, which leads to large clinic costs. Most outpatient clinics only able to see patients once a week.

Research of effects of biofilm in chronic wounds and effects of Qoustic Wound Therapy (QWT) on biofilm was done and summary would be shown in abstract

Case study was done to investigate if addition of Qoustic Wound Therapy using sensitivity proven antibiotic and / or antimicrobial solution would disrupt biofilm and prolong time of formation.

Five patients with each treatment modality would be demonstrated in abstract / poster

Results – three out of five patients treated with debridement / antimicrobial dressings, had no bacterial growth in 4 days

            – five out of five patients treated with debridement / antimicrobial dressings, had bacterial growth in 7 days

 – three out of five patients treated with debridement / QWT / antimicrobial dressings had no bacterial growth in 7 days

– five out of five patients treated with debridement / / QWT / antimicrobial dressings had no bacterial growth in 4 days

Patients treated with addition of QWT healed faster and did not require systemic antibiotics.

Conclusion – Qoustic Wound Therapy assists with disruption of biofilm and penetration of antimicrobial agent, leading to prolonging biofilm rebuilt time and faster healing.
