Research Article: Effect of cold atmospheric plasma therapy on wound healing in patients with diabetic foot ulcers: protocol for a systematic review and meta-analysis

Date Published: 2023-04-27

Abstract:
Introduction Diabetic foot ulcer (DFU), one of the most common and serious consequences of diabetes, affects many individuals and often leads to amputation, death and other disastrous outcomes. Diabetic foot ulcers have a relatively poor response to therapy, which increases the likelihood of recurrence. Cold atmospheric plasma (CAP) therapy is an emerging treatment method for DFU that can reduce bacterial loads and speed up the healing of chronic wounds. Although some studies have reported that CAP could improve the wound healing speed compared with conventional traditional therapy, the samples in these studies are small and not sufficiently representative. The purpose of the current systematic review and meta-analysis is to evaluate the effectiveness and safety of CAP in DFU treatment and provide a scientific basis for its clinical application. Methods and analysis The following databases will be searched: Wanfang, China Biology and Medicine CD, Embase, PubMed and The Cochrane Library. We will retrieve publications, conference documents, current trials and internal reports written in English or Chinese related to the effect of CAP therapy on wound healing in patients with diabetic foot ulcers up to 30 June 2022. The selected articles will be read independently by two reviewers, and valid information such as first author, publication date and outcome indicators will be extracted. Researchers will also assess the quality of the literature using the Cochrane risk-of-bias tool 2. RevMan 5.3.5, EndNote X7 and STATA V.13.0 will be used for data analysis. Ethics and dissemination No ethical review is necessary for this systematic review because it is based on previously published data and does not include patient intervention. A peer-reviewed publication will publish the findings of this investigation.

Introduction:
According to the International Diabetes Federation, approximately 537?million adults (aged 20–79) worldwide suffered from diabetes in 2021, with approximately 6.7?million people dying as a result of diabetes or its complications. 1 Diabetic foot ulcer (DFU) is one of the most devastating consequences of diabetes and a substantial contributor to disability. Studies have reported that the lifetime prevalence of DFUs is 19%–34%, and the recurrence rate of ulcers following wound healing is as high as 40%. 2 Patients…
