COVID-19疫情期间非隔离诊区超声设备的消毒

Disinfection of ultrasonic equipment in non-isolated diagnosis area in COVID-19 epidemic situation

面对当前全球新型冠状病毒肺炎(COVID-19)疫情的严峻形势,医院通过采取科学的清洁、消毒、隔离以及个人防护措施,可有效预防和控制院内感染,遏制疫情扩散。为最小化超声检查相关的交叉污染风险,超声医务人员不仅须在隔离诊区进行严格的感染防控,在非隔离诊区也必须执行规范化的超声设备消毒流程。在对超声设备进行彻底清洁和干燥后,根据超声操作类别选择适当的消毒方式:对接触完整皮肤的超声探头实施低级别消毒,如使用季铵盐消毒湿巾进行擦拭;腔内超声、介入操作、接触感染或破损的皮肤时,必须对包括超声探头在内的直接与患者接触的设备实施高级别消毒,在此基础上,还需在超声检查时使用一次性探头套和穿刺架。此外,超声医务人员须注意耦合剂的正确选择和使用,以及超声设备其他部件的清洁和消毒,以降低超声检查相关的感染风险,保护就诊患者的安全。

During coronavirus disease 2019(COVID-19)pandemic,hospitals adopt effective measures including cleaning,disinfection,isolation and personal protection,aiming to prevent nosocomial infections and control the epidemic spread.In order to minimize the risk of cross-contamination associated with ultrasound examinations,ultrasound practitioners carry out strict infection control in the isolated area,and implement standardized procedures of equipment disinfection in the non-isolated area.After cleaning and drying the equipment,ultrasound practitioners should select an appropriate disinfection method based on the respective examination or intervention.Low level disinfection,such as wiping with quaternary ammonium salt disinfecting wipes,is sufficient for standard ultrasound examinations on intact skin.High level disinfection is mandatory after endo-cavity ultrasound examinations,intervention procedures,or ultrasound examinations on infected/broken skin.In addition,disposable transducer covers and needle guides are recommended to use in such situation.Furthermore,infection risk can be reduced through adequate use of ultrasound gel,as well as decontamination of other equipment components.
