Cross-infection by contaminated equipment is a potential hazard associated with conscious sedation with nitrous oxide and oxygen . Nosocomial infections have occasionally been linked wih the use of unsterile inhalation devices; microbial contamination of sterile nasal hoods routinely occurs during administration of nitrous oxide; and in vitro experiments indicate that subsequent use of contaminated nasal masks may lead to aspiration of microorganisms. Although the incidence of respiratory disease after such contamination is unknown, it is clear that disinfection of the nitrous oxide apparatus between patients is desirable. A simple cleaning method involving alkaline glutaraldehyde is described that provides adequate disinfection of the rubber goods used in the administration of gas. Superiority of this technique over previously recommended cleaning methods is shown.
受污染设备导致的交叉感染是与一氧化二氮和氧气清醒镇静相关的潜在危害。医院感染偶尔与使用未消毒的吸入装置有关；在一氧化二氮给药过程中，无菌鼻罩经常会发生微生物污染；体外实验表明，随后使用受污染的鼻罩可能导致微生物吸入。虽然这种污染后呼吸道疾病的发生率尚不清楚，但很明显，在患者之间对一氧化二氮设备进行消毒是可取的。本文描述了一种使用碱性戊二醛的简单清洁方法，该方法能对气体给药中使用的橡胶制品进行充分消毒。结果表明，该技术优于先前推荐的清洁方法。
