Abstract
Background: Negative pressure wound therapy (NPWT) has revolutionised the management of complex wounds via mechanisms such as microdeformation, angiogenesis and exudate control. However, its clinical effect has historically only been evaluated by qualitative and visual parameters. This study integrates near-infrared spectroscopy (NIRS) as a biofeedback tool to quantify physiological response to NPWT in real time.
Objective: This study aimed to quantitatively demonstrate the physiological and structural changes induced by an NPWT system in patients with complex wounds, measured using NIRS.
Methods: A prospective real-world observational study was conducted with a cohort of 23 patients with 33 wounds. Structural and physiological parameters were documented before and after NPWT treatment. Random-intercept mixed-effect statistical models and pre-post comparison tests were used to assess clinical and physiological significance.
Results: The data showed a progressive reduction in wound area and volume, accompanied by an increase in tissue oxygen saturation and a sustained decrease in deoxygenated haemoglobin. These findings, objectively quantified through NIRS as a real-time biofeedback tool, highlight the improvement in oxygenation and wound-bed perfusion and support the hypothesis of tissue biomodulation induced by NPWT.
Conclusion: The integration of NIRS redefines the clinical role of NPWT, allowing therapy to be customised based on specific physiological data. This combination represents a new frontier in precision wound medicine. The results of this study provide a foundation for a new generation of clinical decisions in advanced wound management.
期刊介绍：
Journal of Wound Care (JWC) is the definitive wound-care journal and the leading source of up-to-date research and clinical information on everything related to tissue viability. The journal was first launched in 1992 and aimed at catering to the needs of the multidisciplinary team. Published monthly, the journal’s international audience includes nurses, doctors and researchers specialising in wound management and tissue viability, as well as generalists wishing to enhance their practice.
In addition to cutting edge and state-of-the-art research and practice articles, JWC also covers topics related to wound-care management, education and novel therapies, as well as JWC cases supplements, a supplement dedicated solely to case reports and case series in wound care. All articles are rigorously peer-reviewed by a panel of international experts, comprised of clinicians, nurses and researchers.
Specifically, JWC publishes:
High quality evidence on all aspects of wound care, including leg ulcers, pressure ulcers, the diabetic foot, burns, surgical wounds, wound infection and more
The latest developments and innovations in wound care through both preclinical and preliminary clinical trials of potential new treatments worldwide
In-depth prospective studies of new treatment applications, as well as high-level research evidence on existing treatments
Clinical case studies providing information on how to deal with complex wounds
Comprehensive literature reviews on current concepts and practice, including cost-effectiveness
Updates on the activities of wound care societies around the world.
