A clinical randomized trial was performed to determine whether a simple homemade wound vacuum-dressing system (HM-VAC) is a feasible alternative to the use of conventional saline-soaked gauze dressings (WET) for the treatment of complex wounds in a resource-poor hospital.
Forty patients were analyzed to compare the HM-VAC and the WET dressings. The HM-VAC was assembled with tools available in most operating room worldwide. The primary outcome measure was the time of complete wound healing. Additionally, the costs of both methods were calculated.
The time required to achieve complete healing was 16 days in the HM-VAC group compared with 25 days in the WET group (P = .013). The HM-VAC costs US $360 per case, and the WET technique costs US $271 per case (P = .008).
The HM-VAC should be considered in underdeveloped countries to provide modern management for complex wounds because healing is significantly faster compared with conventional wound care. Although the HM-VAC is more costly than the conventional approach, it is probably affordable for most resource-poor hospitals.
一项临床随机试验旨在确定一种简单的自制伤口负压敷料系统(HM-VAC)是否可以替代传统的盐水浸湿纱布敷料(WET),用于资源匮乏的医院中治疗复杂伤口。
分析了 40 例患者,比较了 HM-VAC 和 WET 敷料。HM-VAC 是用全球大多数手术室都有的工具组装而成的。主要的观察指标是完全愈合所需的时间。此外,还计算了两种方法的成本。
HM-VAC 组完全愈合所需的时间为 16 天,而 WET 组为 25 天(P=0.013)。HM-VAC 的每个病例成本为 360 美元,而 WET 技术的每个病例成本为 271 美元(P=0.008)。
HM-VAC 应在欠发达国家中考虑使用,为复杂伤口提供现代管理,因为与传统伤口护理相比,愈合速度明显更快。尽管 HM-VAC 比传统方法更昂贵,但对于大多数资源匮乏的医院来说,它可能是负担得起的。
