目的研究皮肤消毒范围对预防中心静脉导管血流感染效果的影响。方法采用细菌培养法和临床观察,对扩大中心静脉置管穿刺部位皮肤消毒范围及其置管期间护理消毒效果进行观察。结果将中心静脉置管部位皮肤消毒范围由5cm×5cm扩大到10cm×12cm,试验组患者中心静脉置管穿刺口及其周围皮肤和导管尖端细菌培养阳性率分别为20.6%、24.7%和16.9%。消毒范围仍为5cm×5cm的对照组患者相同部位细菌培养阳性率分别为28.8%、32.5%和26.9%。试验组患者导管相关性血流感染发生率为1.56%,对照组患者为4.38%。结论中心静脉置管部位皮肤扩大消毒范围对于有效防控中心静脉导管血流感染的发生具有明显效果,值得推广使用。
Objective To study the effect of skin disinfection range on the prevention of central venous catheter bloodstream infection. Methods Bacterial culture method and clinical observation were used to observe the range of skin disinfection and the nursing disinfection effect during catheterization in central venous catheter. Results The range of skin disinfection of central venous catheter was expanded from 5cm × 5cm to 10cm × 12cm. The positive rates of bacterial culture in central venous catheterization and surrounding skin and catheter tip were 20.6%, 24.7% and 16.9% respectively in test group, . The positive rate of bacterial culture in the same part of the control group with the disinfection range of 5cm × 5cm was 28.8%, 32.5% and 26.9% respectively. The incidence of catheter-related bloodstream infections was 1.56% in the test group and 4.38% in the control group. Conclusion Central venous catheter site to expand the scope of disinfection of the central venous catheter for effective prevention and control of bloodstream infection has a significant effect, it is worth promoting the use of.
