The aim of this study is to review the current evidence-based data regarding strategies for prevention of central venous catheter (CVC) infections at the time of catheter insertion and as a part of routine care.
We conducted a PubMed search from January 1990 to November 2010 using the following keywords: central venous catheter, clinical trials, pediatric, infection, prevention, antibiotic, chlorhexidine, dressing, antiseptic impregnated catheters, ethanol lock, impregnated cuff, insertion site infection, and Cochrane systematic review. Seven questions, selected by the American Pediatric Surgical Association Outcomes and Clinical Trials Committee, were addressed.
Thirty-six studies were selected for detailed review based on the strength of their study design and relevance to our 7 questions. These studies provide evidence that (1) chlorhexidine skin prep and chlorhexidine-impregnated dressing can decrease CVC colonization and bloodstream infection, (2) use of heparin and antibiotic-impregnated CVCs can decrease CVC colonization and bloodstream infection, and (3) ethanol and vancomycin lock therapy can reduce the incidence of catheter-associated bloodstream infections.
Grade A and B recommendations can be made based on available evidence in adult and limited pediatric studies for multiple components of proper CVC insertion practices and subsequent management. These strategies can minimize the risk of CVC infections in pediatric patients.
本研究旨在回顾目前有关在导管插入时和常规护理过程中预防中心静脉导管(CVC)感染的循证数据。
我们使用以下关键词在 PubMed 上进行了 1990 年 1 月至 2010 年 11 月的搜索:中心静脉导管、临床试验、儿科、感染、预防、抗生素、洗必泰、敷料、抗菌浸渍导管、乙醇封管、浸渍袖口、插入部位感染和 Cochrane 系统评价。根据美国儿外科协会结局和临床试验委员会选择了七个问题进行了讨论。
根据研究设计的强度和与我们的 7 个问题的相关性,选择了 36 项研究进行详细审查。这些研究提供了证据表明:(1)洗必泰皮肤准备和洗必泰浸渍敷料可以减少 CVC 定植和血流感染,(2)使用肝素和抗生素浸渍的 CVC 可以减少 CVC 定植和血流感染,以及(3)乙醇和万古霉素封管治疗可以降低导管相关性血流感染的发生率。
根据成人和有限的儿科研究中的可用证据,可以对适当的 CVC 插入实践和后续管理的多个组成部分提出 A 级和 B 级推荐。这些策略可以最大限度地降低儿科患者 CVC 感染的风险。
