深静脉置管感染原因分析及护理对策

The Analysis of the Cause of Deep Venous Catheter Infection and Nursing Strategy

目的:对深静脉置管感染的原因进行分析,并提出对应的护理对策。方法:对205例深静脉置管术后患者进行导管内外导管段和外周静脉血采样细菌培养,观察阳性结果并进行分析。结果:导管放置时间与感染的发生存在明显相关性,深静脉置管的时间越长,患者出现感染的几率越大;外周静脉血细菌培养的阳性率明显较导管内外段培养阳性率低,差异具有统计学意义(P<0.05),导管血的细菌主要以G+菌为主。结论:深静脉置管感染是置管时间、导管污染等多种原因引起的,在对患者进行护理时须对这些因素加强控制,减少深静脉置管感染的发生。

Objective：To analyze the cause of deep venous catheter infection and propose the corresponding nursing measures.Methods：205 cases of deep venous catheterization patients after catheter were taken for inside and outside the catheter segment and peripheral venous blood sampling bacterial cultures,the positive results were observed and analysis.Results：The catheter placement time and infection were significantly correlated,the longer the deep venous catheterization,the higher the chances of patients infected.The culture-positive rate of outside the segment was significantly lower than the peripheral blood bacterial culture positive rate of inside segment,the difference was statistically significant（P0.05）.The catheter blood of bacteria was mainly with G＋ bacteria.Conclusion：The deep venous catheter infection is caused by catheter time,catheter contamination and other causes.In the care of patients,the factors should be enhanced control to reduce the incidence of deep venous catheter infection.
