Abstract

Introduction: Chronic ulcers are the main cause of morbidity and mortality, and the incidence of chronic wounds is expected to increase given that people live longer and that there are civil diseases.

Aim: Much attention in the treatment of wounds concerns a dressing that involves wound cleansing, bacterial balance, exudate management and local tissue in a wound environment. These important elements of the evaluation led to the development of an interactive dressing based entirely on flax raw materials.

Material and methods: The complete dressing for wound coverage was prepared from plant (flax) row products: seedcakes, oil, fiber. The content of bioactive compounds (qualitatively and quantitatively) was tested using chromatographic techniques, and their biological activity during tests on fibroblast cell cultures (NHDF). As a final step the clinical trial were performed.

Results: The dressings, which help control the microenvironment, combining with exudate using hydrophilic fibre, controlling the flow of exudate from the wound to the dressing were generated. They stimulate the activity in the healing cascade and accelerate the healing process by combining lignocellulose fibre with higher amounts of phenolic compounds, sterols, cannabidiol and unsaturated fatty acids simultaneously with the 3-hydroxybutyrate polymer. All constituents of linen dressing are natural, originate from two types of the engineered flax plant. Pre-clinical data reveal a reasonable reduction in wound size in patients with chronic leg ulcers treated with a linen dressing.

Conclusions: For the first time, a successful application of the innovative interactive linen dressing in the treatment of chronic wounds was noted.
