Negative pressure wound therapy (NPWT) is an alternative to standard treatment of acute wounds (such as traumatic or postoperative wounds) but also in that of chronic wounds (such as ulcers or stage 3 and 4 pressure ulcers). With cellular, extracellular effects and bacterial clearance, it leads to the rapid formation of healthy budding granulation tissue, which provides wound bed for directed healing or secondary coverage by skin graft or flap. However, the exorbitant cost of VAC (vacuum-assisted closure) devices for our limited resources health facilities and their unavailability led us to opt for a “low cost” solution using wall suction and disposable materials readily available in all surgical departments. We present the technique used in our department and its results through a series of 3 cases with both acute and chronic lesions evolving in septic environment and where NPWT enabled us to ensure a genuine care protocol until healing while reducing the cost of therapy, the number of dressings and the length of hospital stay.

急性和慢性伤口的“低成本”负压伤口治疗：案例系列

负压伤口疗法 (NPWT) 是急性伤口（如外伤或术后伤口）标准治疗的替代方案，也是慢性伤口（如溃疡或 3 和 4 期压疮）的替代方案。通过细胞、细胞外效应和细菌清除，它会导致健康的芽生肉芽组织快速形成，从而为伤口床提供定向愈合或通过皮肤移植物或皮瓣进行二次覆盖。然而，由于 VAC（真空辅助闭合）设备对我们资源有限的医疗机构而言成本过高，而且无法获得，因此我们选择了一种“低成本”的解决方案，即使用壁式抽吸装置和所有外科部门均可使用的一次性材料。
