Abstract:ObjectiveTo study the effect of different skin disinfectant on the prevention of catheterrelated bloodstream infection (CRBSI). MethodsClinical control study was used to compare the difference in incidences of CRBSI in patients who used compound skin disinfectant and 2% chlorhexidine gluconate (CHG) alcohol skin disinfectant before central venous catheterization in the intensive care unit of a tertiary first class hospital between December 2011 and May 2014. ResultsAmong patients who used 2% CHG alcohol skin disinfectant, 2 had CRBSI, one was gramnegative bacterial infection (Pseudomonas aeruginosa), and the other was grampositive bacterial infection (Staphylococcus aureus),incidence of CRBSI was 0.44‰(2/4 546); among patients who used compound skin disinfectant, 22 had CRBSI, 13 were gramnegative bacterial infection, 7 were grampositive bacterial infection, and 2 were fungal infection, incidence of CRBSI was 4.11‰(22/5 349), incidence of CRBSI between two groups of patients was significantly different (χ2=15.640,P<0.01). Conclusion2% CHG alcohol skin disinfectant has a better effect on the skin disinfection before central venous catheterization, which can effectively reduce the incidence of CRBSI in ICU patients, and is worthy of priority clinical application.
