Ultrasonic-Assisted Wound Debridement (UAW)
Thorough and selective
Around 4 million people in Germany suffer from chronic wounds. Experts assume an annual incidence rate of 8 patients per 1,000 inhabitants, which translates to 650,000 new chronic ulcers per year. This number conceals the sad fate of many individuals and high costs. The treatment of chronic wounds is complicated and the condition usually endures for months or even years.
In addition to the treatment of the underlying condition, delayed healing of the wounds caused by necroses, coverings and the colonisation of bacteria, particularly in biofilms, is one of the challenges associated with chronic ulcers. In addition to the treatment of the underlying conditions, such as diabetes or venous and peripheral arterial circulatory disorders, conditioning of the wound floor via debridement has an important role in wound treatment.
There are a number of methods available for the removal of necrotic, damaged and/or infected tissue from wounds. These include:
- Water jet irrigation
- Ultrasonic assisted wound treatment (UAW)
Advantages of ultrasonic assisted wound treatment (UAW): selective mode of action and efficient debridement
Ultrasonic assisted wound treatment is primarily based on the cavitation effect generated by low-frequency ultrasound. During the process, the ultrasound distinguishes between necrotic and healthy tissue. Necroses, damaged tissue and even biofilm formations are removed without any damage occurring to the healthy tissue.
This selective approach offers a range of advantages:
- Return of the wound to an acute stage thereby promoting granulation
- Existing granulation tissue is preserved
- Avital tissue is detached and flushed out
- Significant reduction of germs, even in biofilm formations that are difficult to access
- Application in wound areas that are difficult to access e.g. fistula tracts
- Less pain for patient
- The use of UAW generates considerable cost savings
- Effective wound cleaning reduces the number of debridements
- Quicker initial sealing
- Reduced use of analgesics as treatment is less painful
- No surgical intervention necessary as the UAW reaches wound pockets and fistula tracts, etc., that are difficult to access.
- Venous ulcers of venous and arterial origin
- Diabetic foot syndrome
- Decubitus ulcers (bedsores)
- Infected acute wounds
- Burns and scalds
- Cleaning of septic wounds
