封管液对预防导管相关血流感染的研究进展

Research advances in the prevention of catheter-related bloodstream infection by locking solution

摘要:

导管相关血流感染是导致静脉导管置管患者死亡的重要因素之一。导管封管液的选择成为维护静脉导管环节的重要组成部分, 不同化学成分的封管液对预防导管相关血流感染发生的效果存在差异。因此, 选择适合有效的溶液进行封管, 是降低血管导管相关感染发生的重要方法。现就国内外单一化学成分及其复合成分的不同类型封管液对预防导管相关血流感染现状进行综述, 以期为临床医务人员对封管液的选择及进一步研究提供理论参考。

Abstract:

Catheter-related bloodstream infection (CRBSI) is an important factor leading to death in patients with venous catheterization. Selection of catheter locking solution has become an important part in maintaining venous catheter. Locking solution with different chemical components have different effects on preventing CRBSI. Therefore, selecting a suitable and effective solution for locking is an important method to reduce the occurrence of CRBSI. This paper reviews different types of domestic and foreign locking solutions with single or compound chemical compositions in the prevention of CRBSI, so as to provide theoretical reference for clinical health care workers in the selection and further research in locking solution.
