摘要

简介和重要性：用传统的伤口疗法治疗软组织缺损往往是不够的。真空辅助闭合（VAC）已被证明是一种有效的方法，用于排出物，减少水肿，灌注增强和肉芽组织刺激。本研究评估了新型的反向水泵真空辅助封闭（RAP-VAC），这是发展中国家的一种低成本创新选择，旨在促进伤口成功愈合，同时减轻经济限制。病例介绍：本系列病例报告于印度尼西亚一家三级转诊医院，涉及13例使用RAP-VAC治疗软组织缺损的患者。平均伤口大小减少了9.8%，从第0天的50.19±36.96 cm2减少到终点测量的45.25±36.43 cm2。平均肉芽率为92.13%，平均创面准备时间为20.92±2.69 d。每名患者的护理费用总额为2,376,923印尼盾。线性混合模型分析与50.19 （p = 0.001）的截距估计显著相关，结果每天减少0.32 （p = 0.010）。临床讨论：NPWT由于持续负压导致伤口收缩加快。机械运动促进细胞迁移，从而加快伤口愈合。NPWT的成本效益已经确立，减少了昂贵治疗的必要性。一项研究报告使用了基于水泵的VAC，但没有详细说明其机制。相反，我们的设备将风扇方向反转以提高吸力。我们采用IMITO应用测量进行客观评价。RAP-VAC系统的特点是成本低，在发展中国家可以提供可观的经济效益，同时保持治疗效果，是医院和社区护理环境中伤口管理的可行选择。结论：RAP-VAC能有效促进创面愈合，是替代昂贵的VAC系统的一种经济有效的方法。

Reverse aqua pump vacuum-assisted closure alternative and affordable solution for emerging cost in wound therapy: A case series

Introduction and importance

Soft tissue defects managed with conventional wound therapies are often inadequate. Vacuum-Assisted Closure (VAC) has proven to be an effective method for discharge removal, edema reduction, perfusion enhancement, and granulation tissue stimulation. This study assesses the novel Reverse Aqua Pump Vacuum-Assisted Closure (RAP-VAC), a low-cost innovation option in a developing country, designed to facilitate successful wound healing while mitigating financial limitations.

Case presentation

This case series was reported at a tertiary referral hospital in Indonesia, involving 13 patients with soft tissue defects utilizing RAP-VAC. The average wound size diminished by 9.8 %, from 50.19 ± 36.96 cm² on day 0 to 45.25 ± 36.43 cm² at the endpoint measurement. The mean granulation rate was 92.13 %, and the average wound bed preparation duration was 20.92 ± 2.69 days. The whole expenditure for care expenses to IDR 2,376,923 per patient. The linear mixed model analysis significantly associated with intercept estimate of 50.19 (p = 0.001) with 0.32 reduction per day in the outcome (p = 0.010).

Clinical discussion

NPWT accelerates wound shrinkage, resulting from the consistent negative pressure. The mechanical motion facilitates cell migration, hence expediting wound closure. The cost-effectiveness of NPWT has been established, diminishing the necessity for expensive therapies. A study reported using an aqua pump-based VAC, but without detailing the mechanism. In contrast, our device reverses the fan direction for improved suction. We employed the IMITO app measurement for objective evaluation. The RAP-VAC system, characterized by low costs, may provide substantial financial benefits while maintaining therapeutic outcomes in developing countries, as a viable choice for wound management in both hospital and community care environments.
