An examination of methods for disinfecting a neonatal intensive care unit incubator.

本研究旨在表征高温、高湿环境中封闭式婴儿培养箱内的细菌种类，并确定此类培养箱的清洁和消毒效果。我们比较了不同清洁方法的有效性：我们用消毒剂清洁了一组正在使用的培养箱，而另一组则使用了不含任何消毒剂的干擦拭巾。我们没有从两个培养箱组中检测到任何细菌。这些结果表明，在没有任何其他诱发因素的情况下，单独的高温高湿环境不会增加培养箱内的细菌数量。这意味着在培养箱内检测到的细菌来源于新生儿，新生儿在出生后或通过治疗和护理增加污染机会而获得细菌植物群。

This study aims to characterize the bacterial species inside closed infant incubators in a high temperature, high humidity environment and to determine the effectiveness of cleaning and disinfecting such incubators. We compared the effectiveness of different cleaning methods: we cleaned one group of incubators in use with disinfectant and another group using a dry wipe without any disinfectants. We did not detect any bacteria from both incubator groups. These results suggest that a high temperature, high humidity environment alone does not increase the amount of bacteria inside an incubator without any other predisposing factors. This implies that the bacteria detected inside an incubator originates from a newborn infant who acquires a bacterial flora after birth or through increased opportunities for contamination through treatment and care.
