Chronic wounds have a high incidence and a long course of disease, and will bring a heavy economic burden to patients, which is the difficulty of clinical treatment at present. Therefore, it is urgent to find an effective method to promote chronic wound healing. In recent years, the application of therapeutic ultrasound in chronic wound treatment has gradually gained attention, and has become a promising adjuvant therapy. This article reviews the process of wound healing, the mechanism of therapeutic ultrasound in promoting wound healing, the biological effects of therapeutic ultrasound in different stages of wound healing and its application in diabetic ulcer, venous ulcer of lower limbs and pressure ulcer, in order to provide new ideas and directions for the treatment of chronic wounds.
Objective To summarize the optimal evidence for improving the management of chronic wounds exudate, so as to provide evidence-based references for medical professionals, therapists, patients, and their caregivers. Methods PubMed, Wanfang, CNKI, Medlive, UpToDate, etc., were searched by computer for literature about chronic trauma exudate management. The retrieval time limit was from 1998 to 2023. Two researchers trained in evidence-based practice evaluated the quality of the included literature and finally extracted evidence from the literature that met the quality evaluation criteria. Results A total of 11 articles were included, including 2 expert consensuses, 7 systematic reviews, 1 randomized controlled trial, and 1 guideline, covering 7 aspects of the assessment of the nature of chronic wounds exudate, selection of exudate assessment tools, management of antimicrobial concerns, selection and application of wound dressings, negative pressure wound drainage therapy, wound drainage bags, and affected limb elevation or compression therapy for patients with venous leg ulcers. A total of 13 best evidences were extracted. Conclusions When applying evidence, medical professionals should fully evaluate and combine the individual circumstances of the patient, make full use of existing resources, new treatment concepts and technologies, and carry out comprehensive integrated management. This can optimize the management of chronic wounds exudate and improve the quality of life of patients.
Skin trauma is a global public health issue, and chronic wound healing is complex. Its care faces problems such as long cycles and poor outcomes. In recent years, research on novel wound dressings and nursing methods has gradually increased, but there is still a lack of systematic summary of nanomaterials dressings for repairing chronic skin wounds. This article reviews the application and nursing effects of nanomaterials dressings in chronic wound repair, explores their potential, and looks forward to the research directions of chronic wound prevention, science popularization, and service system construction, providing a reference for the clinical application of nanomaterials.
