Evaluation of the Biophysical Signs of Healing in the Protocolized Use of the High Capillarity Dressing: A Pilot Study

The aim of this study was to evaluate the effects of a high-capillarity dressing on chronic wound healing, using hyperspectral imaging to assess biophysical parameters. This quasi-experimental pilot study involved eight adults with chronic ulcers treated with the high-capillarity dressing for 4 weeks. Primary outcomes included pH, temperature, and oxygen saturation, measured using hyperspectral imaging, along with wound area assessed with ImageJ. Secondary outcomes included quality of life, evaluated using the EQ-5D-5L and Wound QoL-17 scales. Data were collected at baseline, 7, 14, and 21 days, and analysed using SPSS. Results showed a significant reduction in lesion size (p < 0.05) and pain (p < 0.001) following treatment. Biophysical assessments revealed a significant decrease in pH (p = 0.004), but no significant changes were observed in other parameters (oxygen saturation, NIR, TWI, TLI). A significant correlation was found between oxygen saturation and pH (p < 0.005). The results suggest that the high-capillarity dressing improves chronic wound healing by reducing lesion size, promoting pH acidification, and improving superficial oxygenation. Additionally, the dressing controlled edema and eliminated infection signs without antibiotics, suggesting its potential in optimising the wound healing environment. These findings highlight the need for further research into the clinical application of this dressing in chronic wound management.
