Complex hard-to-heal wounds are difficult to manage, generating significant expense to the US healthcare system, costing nearly $25 billion annually. Recently, a resorbable synthetic nanofibre matrix was trialled on a variety of complex hard-to-heal wounds at Astria Sunnyside Hospital to assess clinical efficacy.
In this case series, five patients with multiple comorbidities presented in both the inpatient and outpatient setting with various hard-to-heal refractory wounds, including a venous leg ulcer (n=1), a diabetic foot ulcer (n=1), a Charcot foot deformity (n=1) and pressure ulcers (n=2). In an effort to treat these hard-to-heal wounds using a different treatment modality, each patient was transitioned to a care regimen utilising the synthetic nanofibre matrix.
Each patient, regardless of wound type, exhibited the formation of granulation tissue and a reduction in wound size. The application of this synthetic nanofibre matrix also resulted in tissue coverage over exposed structure in three cases, reduction of wound exudate in two cases, and eliminated a recurring infection with and without antibiotics in four cases.
In this study, the treatment of hard-to-heal refractory wounds with the synthetic nanofibre matrix resulted in the desired biological responses and new tissue formation. Inclusion of the nanofibre matrix in inpatient and outpatient wound care settings may provide a much-needed solution for costly, difficult-to-treat, hard-to-heal wounds, and may offer a reduction in the total cost of care.
复杂难愈性伤口难以处理,给美国医疗系统带来了巨大开支,每年花费近250亿美元。最近,一种可吸收的合成纳米纤维基质在阿斯特里亚阳光医院的多种复杂难愈性伤口上进行了试验,以评估其临床疗效。
在这个病例系列中,五名患有多种合并症的患者在住院和门诊环境中出现了各种难愈性难治性伤口,包括下肢静脉溃疡(n = 1)、糖尿病足溃疡(n = 1)、夏科氏足畸形(n = 1)和压疮(n = 2)。为了使用不同的治疗方式治疗这些难愈性伤口,每位患者都过渡到使用合成纳米纤维基质的护理方案。
每位患者,无论伤口类型如何,均表现出肉芽组织形成且伤口大小减小。这种合成纳米纤维基质的应用还导致三例患者覆盖了暴露结构的组织,两例患者伤口渗出物减少,四例患者无论是否使用抗生素都消除了复发性感染。
在本研究中,用合成纳米纤维基质治疗难愈性难治性伤口产生了预期的生物学反应和新组织形成。在住院和门诊伤口护理环境中使用纳米纤维基质可能为昂贵、难以治疗的难愈性伤口提供急需的解决方案,并可能降低护理总成本。
