中心靜脈導管相關血流感染之預防策略

中心靜脈導管廣泛應用於臨床照護，但高侵襲性使其相關血流感染成為醫院中常見且嚴重的問題。本文簡介中心靜脈導管相關血流感染之危險因子、定義以及發生率，並結合最新臨床研究成果，提供以實證醫學為基礎的預防策略。最有效的核心措施包括組合式照護（care bundle）、建立置放標準流程、完善的教育訓練、每日chlorhexidine gluconate溶液擦澡、超音波輔助置放及定期監測血流感染事件等，均可有效降低血流感染發生率。

Central venous catheters are widely used in clinical care; however, their high invasiveness makes catheter-related bloodstream infections a common and serious issue in hospitals. This article provides an overview of the risk factors, definitions, and incidence of central venous catheter-related bloodstream infections and discusses prevention strategies focused on the latest evidence-based clinical research. The most effective core measures include bundle care, standardized placement procedures, comprehensive education and training, daily chlorhexidine gluconate baths, ultrasound-assisted placement, and regular monitoring of bloodstream infection events, all of which can effectively reduce the incidence of bloodstream infections.
