Abstract：
This case study examines the effectiveness of using negative pressure wound therapy (NPWT) in the management of a hard-to-heal (chronic) wound with exposed ankle bone to reduce associated wound exudate and promote production of granulation tissue. A 60-year-old male patient who was able to attend wound follow-up diligently twice weekly for eight weeks, and weekly thereafter, was selected from a private hospital to take part. During each dressing change, the wound was cleansed with superoxidised cleansing solution, and minimal sharp debridement was performed. In the authors\' opinion, the NPWT device used in this study is light and convenient for use in the community or home care setting. The NPWT wound dressing was connected to the NPWT machine via a connecting tube and the device then switched on using the default setting of a negative pressure of 125mmHg. Following the application of the NPWT device, the exposed ankle bone was successfully covered with healthy granulation tissue and healed within 20 weeks with minimal exudate formation in the wound. In the authors\' opinion, NPWT is able to promote progress to wound healing; to minimise unnecessary dressing changes and, based on feedback from the patient, is comfortable to wear and when in use.
摘要：
本案例研究检查了使用负压伤口治疗（NPWT）治疗踝骨外露的难以愈合（慢性）伤口以减少相关伤口渗出物并促进肉芽组织产生的有效性。一名60岁的男性患者，每周两次，持续八周，此后每周一次，从一家私立医院挑选出来参加。在每次换药期间，用超级氧化的清洁溶液清洁伤口，和最小的尖锐清创术进行。在作者看来，本研究中使用的NPWT装置重量轻,便于在社区或家庭护理环境中使用.将NPWT伤口敷料经由连接管连接到NPWT机器,然后使用125mmHg的负压的默认设置打开装置。在应用NPWT器件之后，暴露的踝骨被健康的肉芽组织成功覆盖，并在20周内愈合，伤口中的渗出物很少。在作者看来，NPWT能够促进伤口愈合;尽量减少不必要的敷料更换，根据病人的反馈,穿着和使用时舒适。
