Arterial Ulcer

Chronic wounds are wounds that do not heal properly over time and can significantly reduce quality of life. Common types include diabetic foot ulcers, venous leg ulcers, and arterial ulcers. Improving wound healing and speeding up skin regeneration (epithelialization) are important goals in the care of these patients. Dexpanthenol is a vitamin B5 derivative that supports skin repair and tissue regeneration. It is widely used in topical treatments, and injectable forms are approved for clinical use. However, the effects of subcutaneous (under the skin) dexpanthenol injections on chronic wound healing have not been sufficiently studied in clinical settings. The purpose of this study is to evaluate whether adding subcutaneous dexpanthenol injections to standard wound care improves wound healing compared with standard wound care alone. Adult patients with non-infected chronic wounds will be randomly assigned to one of two groups. One group will receive standard wound care only, while the other group will receive standard wound care plus subcutaneous dexpanthenol injections around the wound area. Wound healing will be assessed by measuring changes in wound size and the degree of skin epithelialization over time using standardized and objective methods. Safety will be monitored by recording local reactions at the injection site and any other adverse events during the study. The results of this study may provide preliminary clinical evidence on the effectiveness and safety of subcutaneous dexpanthenol as an additional treatment option for chronic wound management.

The goal of this randomized controlled trial is to evaluate the efficacy and safety of a novel hydrogel made of Carbopol® 940 functionalized with Plasma-Activated Water (PAW) in patients with chronic wounds (diabetic foot ulcers, pressure injuries, dehiscent wounds, arterial and venous ulcers). The main questions it aims to answer are: * Does PAW-hydrogel accelerate wound closure (reduction in surface area) compared to standard advanced wound care? * Does PAW-hydrogel reduce bacterial load in the wound bed? * Is PAW-hydrogel safe and well-tolerated (local adverse events, pain)? Participants will be randomly assigned to one of two groups: * Experimental group: Topical application of PAW-hydrogel (Carbopol® 940 neutralized to pH 5.5, loaded with reactive oxygen and nitrogen species from plasma activation) 2-3 times per week. * Control group: Standard advanced wound care (cleaning, debridement, conventional dressings). Wound area (planimetry), bacterial load (semi-quantitative cultures), pain (Visual Analog Scale), tissue quality (Bates-Jensen scale), and adverse events will be assessed over a 12-week follow-up period.
