A New Therapy for Difficult Wounds

Treatment with EmoLED is indicated for acute and chronic lesions such as leg ulcers (venous, mixed, and arterial), surgical separation, inflammatory ulcers (vasculitis), post-traumatic ulcers, scleroderma ulcers, neuro-ischemic ulcers of the diabetic foot, compression and skin. Graft ulcers in patients over 16 years of age.
Except for neoplastic lesions and lesions in patients with porphyria, there are no particular restrictions on the type of skin lesions that can be treated with EmoLED. No side effects were found in the treatment and no adverse events related to the use of the device occurred.
EmoLED treatment is done in addition to the standard treatment and is done at the dressing change.

Therapeutic Effects

When applied at least once a week, EmoLED has been found to be effective in reducing wound healing time, inflammation, and pain.
Clinical observations, particularly in venous ulcers and vasculitis, found a significant reduction in pain after four weeks of treatment; this corresponds to the appearance of clinical signs of overcoming inflammatory stasis and reactivating the healing process. In a clinical study (Blue Light for Ulcer Reduction, 2019) on ulcers of various etiologies, predominantly venous, EmoLED treatment resulted in a significant reduction in the surface area of ulcers treated within 10 weeks.
Wound healing begins when the perilesional tissue heals by epithelial margin advancement (edge effect) and as a result, there is a reduction in ulcer sizes, which are key indicators of healing outcome in various types of wounds.

Recommended Exposure and Administration

The recommended standard treatment regimen is at least one EmoLED treatment per week after wound cleansing. For some lesion types (pressure ulcer, diabetic foot ulcer and inflammatory ulcer), twice weekly treatment is recommended following wound cleansing.
The standard treatment time with EmoLED is 60 seconds per affected area; A 120-second treatment per lesion is recommended for diabetic foot and vasculitic ulcers. The area of interest of EmoLED therapy is the wound bed and the skin around the lesion. In case of partial overlap of the treated areas, there are no further risks from overdose or contraindications.
