Mechanical negative pressure wound therapy is an ultraportable, light weight and disposable single-use device that has been shown to promote wound healing. This study evaluated home use of a mechanically powered negative pressure wound therapy (NPWT) in diabetic foot wounds.
Patients underwent revascularisation and/or debridement or amputation before starting mechanical NPWT. Wound outcomes and images of the wounds were recorded at each follow-up visit by the wound nurse. Patients were followed up until wound closure or end of therapy.
A total of 12 patients (each with one wound) were included in the study. Of the 12 wounds, 33.3% (n=4) of wounds achieved primary wound closure while the remaining 66.6% (n=8) of wounds demonstrated a mean wound size reduction of 37.5±0.13%. Of the closed wounds, mean time to healing was 4.75±2.50 weeks. There was 100% limb salvage with no further debridement or amputations, and no 30-day unplanned readmissions. Mean length of hospital stay before starting home NPWT was 9.75±6.31 days. Mean number of NPWT changes was 8.33±2.67 sessions, while mean duration of therapy was 4.0±1.54 weeks. Mean cost of home NWPT therapy was US$1904±731 per patient.
The home use of mechanically powered NPWT in diabetic foot wounds demonstrated excellent wound healing rates and 100% limb salvage, with no complications.
机械负压伤口疗法是一种超便携、重量轻且一次性使用的设备，已被证明可促进伤口愈合。本研究评估了机械驱动负压伤口疗法（NPWT）在家用治疗糖尿病足伤口中的应用。
患者在开始机械 NPWT 前接受了血运重建和/或清创术或截肢术。伤口护士在每次随访时记录伤口的愈合情况和伤口图像。患者接受随访，直至伤口闭合或治疗结束。
共有 12 名患者（每个患者一个伤口）纳入研究。在 12 个伤口中，33.3%（n=4）的伤口实现了一期愈合，而其余 66.6%（n=8）的伤口的平均伤口面积缩小了 37.5±0.13%。在已闭合的伤口中，平均愈合时间为 4.75±2.50 周。所有患者均实现了 100%的肢体挽救，无需进一步清创或截肢，且无 30 天内非计划性再入院。开始家庭 NPWT 前的平均住院时间为 9.75±6.31 天。平均 NPWT 更换次数为 8.33±2.67 次，平均治疗时间为 4.0±1.54 周。每位患者家庭 NPWT 治疗的平均费用为 1904±731 美元。
在家用治疗糖尿病足伤口中应用机械驱动的 NPWT 可实现出色的伤口愈合率和 100%的肢体挽救，且无并发症。
