Lithuanian team develops regenerative dressing for deep wounds

News

Researchers at Lithuania’s Kaunas University of Technology (KTU) are developing a new sponge-like regenerative dressing to treat deep and chronic wounds.

The cost of treating wounds can be substantial, with one study claiming it makes up around 2-4 per cent of total EU healthcare expenditure. Treating just one chronic wound can cost up to €10k, and it is estimated that up to 1.5 per cent of EU population is affected by at least a single wound of this type.

Tissue regeneration is vital for these deep wounds to heal. To address the issue, the Kaunas team is working on sponge-type dressings based on hyaluronic acid, which is a well-researched polymer that stimulates tissue regeneration. Previously, it has been used in ophthalmology, bone regeneration and for other medical and cosmetic purposes.

“Hyaluronic acid is a natural polymer found in living organisms, which has anti-inflammatory properties and stimulates tissue regeneration,” said Odeta Baniukaitienė, researcher at KTU Faculty of Chemical Technology.
