The purpose of this study was to determine the incidence of infectious complications after ultrasound-guided breast interventions performed with an intermediate-level disinfection protocol without an ultrasound probe cover.
Two independent institutional databases were searched to identify breast infections in patients who underwent ultrasound-guided interventions between January 2005 and July 2013. The departments of radiology and infectious diseases independently maintained these databases. A comprehensive retrospective chart review based on periprocedural antibiotic use and clinical documentation of infection was also performed to reduce the likelihood of missing potential infectious complications.
A total of 12,708 ultrasound-guided breast procedures were performed in the time frame of this study. All potential cases of procedure-related infection were included for subspecialist review in an effort to give the most conservative (highest) estimate of infectious complications. Among these cases, 14 documented cases of possible procedure-related infection were identified, for an overall incidence of 0.11%. All infections were localized skin or soft-tissue infections and adequately treated with a short course of oral antibiotics. No cases of more serious infections or sepsis were found. None of the reported infections required IV antibiotic therapy, percutaneous intervention, surgical intervention, or hospitalization.
The incidence of infectious complications after an ultrasound-guided breast intervention without an ultrasound probe cover is extremely low. Physicians can use this information in the development of their disinfection protocols and to provide accurate information in counseling patients during preprocedural consultation.
本研究旨在确定在未使用超声探头套的中级消毒方案下进行超声引导下乳腺介入术后感染并发症的发生率。
检索两个独立的机构数据库，以识别2005年1月至2013年7月期间接受超声引导介入的患者中的乳腺感染情况。放射科和传染病科分别维护这些数据库。还基于围手术期抗生素使用情况和感染的临床记录进行了全面的回顾性图表审查，以降低遗漏潜在感染并发症的可能性。
在本研究时间段内共进行了12,708例超声引导下的乳腺手术。所有可能与手术相关的感染病例均纳入专科医生审查，以给出最保守（最高）的感染并发症估计值。在这些病例中，确定了14例记录在案的可能与手术相关的感染病例，总发生率为0.11%。所有感染均为局限性皮肤或软组织感染，通过短期口服抗生素治疗即可。未发现更严重感染或败血症病例。报告的感染病例均无需静脉抗生素治疗、经皮介入、手术干预或住院治疗。
在未使用超声探头套的情况下进行超声引导下乳腺介入术后感染并发症的发生率极低。医生可利用这些信息制定消毒方案，并在术前咨询期间为患者提供准确信息。
