Reusable nasal-spray devices are frequently used in otolaryngologic examinations, and there is an increasing concern about the risk of cross-contamination from these devices. The aim of our study was to determine, by means of microbiologic analysis, the safety of a positive-displacement or pump-type atomizer after multiple uses.
A reusable nasal spray bottle, pump, and tips were used in the nasal physical examination of 282 patients admitted to a tertiary otolaryngology clinic. The effectiveness of 2 different methods of prophylaxis against microbiologic contamination (the use of protective punched caps or rinsing the bottle tip with alcohol) was compared with that of a control procedure.
Although there was no statistically significant difference in positive culture rates among the types of nasal spray bottles tested, methicillin-resistant coagulase-negative staphylococci were isolated in 4 of 198 cultures.
Given these findings, we concluded that additional precautions (such as the use of an autoclave between sprays, disposable tips, or disposable devices) are warranted to avoid interpatient cross-contamination from a reusable nasal spray device.
可重复使用的鼻喷雾装置常用于耳鼻喉科检查，人们越来越关注这些装置造成交叉污染的风险。我们研究的目的是通过微生物分析确定正位移或泵式雾化器多次使用后的安全性。
在一家三级耳鼻喉科诊所对282例住院患者进行鼻体格检查时，使用了一个可重复使用的鼻喷雾瓶、泵和喷头。将两种不同的预防微生物污染方法（使用带孔保护帽或用酒精冲洗瓶头）的有效性与对照程序进行了比较。
尽管在测试的鼻喷雾瓶类型中，阳性培养率没有统计学上的显著差异，但在198份培养物中有4份分离出耐甲氧西林凝固酶阴性葡萄球菌。
基于这些发现，我们得出结论，有必要采取额外的预防措施（如喷雾之间使用高压灭菌器、一次性喷头或一次性装置），以避免可重复使用的鼻喷雾装置在患者之间造成交叉污染。
