Abstract:
OBJECTIVE To analyze the risk factors of the Catheter-Related Blood Stream Infection(CRBSI) in the intensive care unit(ICU),and to approach effective methods for preventing the CRBSI in ICU.METHODS With the method of objective investigation,all patients in ICU from Jan,2008 to Dec,2008 were studied.The risk factors of CRBSI were investigated.RESULTS 257 patients entered the study.A total of 147 cases suffered from the nosocomial infection(NI).The incidence rate of the NI was 57.2%.Among these,36 cases were dignosised of the CRBSI,and the case-infection rate was 14.07%.The number of CRBSI account for 24.49% of the patients who suffered from the NI.The nosocomial infection rate perday the CRBSI was 16.57‰.It was significantly higher than that of the general wards′.The pathogen detection showed the main pathogen was the G+ bacteria,accounting for 54.04%.Then was the G-bacteria,accounting for 37.84%.The fungus accounted for 8.11%.11 unusual drug resistance bacteria were found(6 ESBLs positive bacteria and 5 MRS bacteria).CONCLUSIONS The incidence of the CRBSI is related to the following reasons: days and the sites of the catheter being placed,the procedure the medical personnel done,the immune function of the patients,and the utilization or unutilization of the high-nutrition drugs through the vein.According to these reasons,strict aseptic technique,reasonable choice of the catheter site,shortening the duration the catheter insertion,and maintaining catheter unobstructed are the keys to prevent the incidence of the CRBSI.
