The CDC category I recommendation for high-level disinfection of pressure-monitoring transducers between uses imposes substantial costs. This practice has not been shown to be useful when disposable transducer domes are used. A prospective, randomized, double-blind study assessed the consequences of wiping transducers with alcohol between uses rather than sterilizing with ethylene oxide. We studied 5,197 transducer courses with disposable domes involving 2,202 patients in intensive care units during 15 months. There was no significant difference between the two treatment regimens in the risk of positive cultures of fluids from monitored lines, of cultures of cannula tips or of a positive blood culture. We conclude that under normal conditions, ie, in the absence of a cluster of transducer-related bacteremias, wiping transducers with alcohol between uses is sufficient when disposable domes are used.
美国疾病控制与预防中心（CDC）关于压力监测换能器在使用之间进行高水平消毒的I类推荐会带来高昂成本。当使用一次性换能器探头时，这种做法并未显示出有用性。一项前瞻性、随机、双盲研究评估了在使用之间用酒精擦拭换能器而非用环氧乙烷消毒的后果。我们在15个月期间研究了5197个使用一次性探头的换能器疗程，涉及重症监护病房的2202名患者。在监测管路液体培养阳性、套管尖端培养阳性或血培养阳性的风险方面，两种治疗方案之间没有显著差异。我们得出结论，在正常情况下，即不存在与换能器相关的菌血症聚集时，使用一次性探头时在使用之间用酒精擦拭换能器就足够了。
