An ultrasound device that fires soundwaves into chronic wounds such as leg ulcers is being used to speed up the healing process.
Research shows treating wounds with high-intensity ultrasound — which helps to clean the wound of debris — can significantly improve the rate at which they heal. Now, a trial is underway to study this exact rate.
Chronic wounds such as diabetic foot ulcers and pressure sores cost the NHS around £1 billion a year to treat. A significant number of the people suffering from chronic wounds have diabetes — one in six people with diabetes will develop a non-healing ulcer. There are a number of treatments, from antibiotics to surgery, but in many cases wounds fail to heal for weeks, months, or years. In severe cases, amputation of a limb may be necessary.
Natural wound healing is a complex process involving many different types of cells moving to the area around a new wound within the first few hours. Their jobs include sealing the wound as quickly as possible, halting blood loss and creating a cover to stop infection.
