OBJECTIVE
Different manufacturers recommend different levels of disinfection for oxygen nipple and nut adaptors, also known as Christmas-tree adaptors (CTAs). We aimed to determine the bacterial contamination rates of CTAs before and after clinical use and whether disinfection wipes effectively eliminate bacteria from CTAs.
METHODS
CTAs were swabbed for bacteria directly from the shipment box or after use in a medical intensive care unit to determine levels of contamination. CTAs were also inoculated in the laboratory with a variety of bacteria and disinfected with either 0.5% hydrogen peroxide (Oxivir 1) or 0.25% tetra-ammonium chloride with 44.50% isopropyl alcohol (Super Sani-Cloth), and the effectiveness of each wipe was determined by comparing the bacterial recovery before and after disinfection.
RESULTS
CTAs exhibit low levels of bacterial burden before and after clinical use. Both disinfecting wipes were effective at removing bacteria from the CTAs.
CONCLUSIONS
Low-level disinfection of CTAs is appropriate prior to redeployment in the clinical setting.
目的
不同制造商建议对氧气奶嘴和螺母适配器（也称为圣诞树适配器（CTA））进行不同水平的消毒。我们旨在确定临床使用前后 CTA 的细菌污染率，以及消毒湿巾是否能有效清除 CTA 上的细菌。
方法
直接从发货箱中或在重症监护病房使用后对 CTA 进行细菌拭子取样，以确定污染程度。还将各种细菌接种到实验室中，并用 0.5%过氧化氢（Oxivir 1）或 0.25%四铵氯化物与 44.50%异丙醇（Super Sani-Cloth）进行消毒，并通过比较消毒前后的细菌回收来确定每种湿巾的有效性。
结果
临床使用前后 CTA 的细菌负担水平较低。两种消毒湿巾都能有效清除 CTA 上的细菌。
结论
在重新部署到临床环境之前，对 CTA 进行低水平消毒是合适的。
