BACKGROUND
Negative pressure wound therapy is now largely used to treat infected wounds. The prevention and reduction of healthcare-associated infections is a high priority for any Department of Health and great efforts are spent to improve infection control systems. It is assumed that vacuum-assisted closure (VAC®) dressings should be watertight and that all the secretions are gathered in a single container but there is no consistent data on air leakage and possible dispersion of bacteria from the machine.
METHODS
We have conducted a prospective experimental study on 10 patients with diagnosis of wound infection to verify whether the filtration process is microbiologically efficient. We compared the bacteria population present in the wound to the one present in the air discharged by the VAC® machine.
RESULTS
This study shows that the contamination of the VAC® machine is considerably lower than the environment or wound contamination.
CONCLUSIONS
Negative pressure wound therapy system does not represent a risk factor for healthcare-associated infections.
背景
负压伤口疗法现在被广泛用于治疗感染性伤口。预防和减少与医疗保健相关的感染是任何卫生部的首要任务，并且花费了大量精力来改善感染控制系统。人们认为真空辅助闭合（VAC®）敷料应该是防水的，并且所有分泌物都收集在一个单独的容器中，但没有关于空气泄漏和机器中细菌可能扩散的一致数据。
方法
我们对 10 名诊断为伤口感染的患者进行了一项前瞻性实验研究，以验证过滤过程是否在微生物学上有效。我们比较了伤口中存在的细菌与 VAC®机器排出的空气中存在的细菌。
结果
这项研究表明，VAC®机器的污染明显低于环境或伤口的污染。
结论
负压伤口治疗系统不是导致医疗保健相关感染的危险因素。
