尊敬的斑竹和院感研究同仁:
近年来有的学者认为needleless connectors可以降低CR-BSI的发生率(Bouza E, Mun˜oz P, Lo´ pez-Rodrı´guez J, et al. A needleless closed system device (CLAVE) protects from intravascular catheter tip and hub colonization: A prospective randomized study. J Hosp Infect 2003; 54:279–87.; Casey AL, Worthington T, Lambert PA, Quinn D, Faroqui MH, Elliott TS. A randomized, prospective clinical trial to assess the potential infection risk associated with the PosiFlow needleless connector. J Hosp Infect 2003; 54:288–93.)。
然而也有些学者提出了反对图意见,认为采用needleless connectors由于消毒困难,反而会增加导管血流感染的发病(Jarvis WR, Murphy C, Hall KK, et al. Health care-associated bloodstream infections associated with negative- or positive-pressure or displacement mechanicalvalve needleless connectors. Clin Infect Dis 2009; 49:1821–7.; Karchmer TB, Cook EM, Palavecino E, et al. Needleless valve ports may be associated with a high rate of catheter-related bloodstream infection [abstract]. In: Program of the 15thAnnual Meeting of the Society for Healthcare Epidemiology of America (Los Angeles, CA). Washington, DC: Society for Healthcare Epidemiology of America, 2005. 307.)
两者似乎存在矛盾,各位临床专家和院感研究同仁,根据您们的实际经验,您们认为呢?
也许未来的systematic review能帮我们解决这个问题!
上一篇:血流感染的主要来源是什么?你知道吗?下一篇:置管(在本院)后定期透析,6月后置管部位出现红肿及分泌物,应属于什么部位感染?
