The epidemiology of venous catheters infection in intensive care unit

Objective To understand the ICU(Intensive care unit,ICU) central venous catheter(central venous catheters,CVC) related bloodstream infection risk factors and analysis of pathogen resistance,provide the basis for clinical treatment.Methods Collecting hospital ICU September 2012 to August 2010 indwelling central venous catheter of 261 inpatients clinical information,the general condition of patients,the occurrence of catheter-related infections(CRBSI) risk factors,the results of bacterial culture and resistant pathogens sexually were retrospectively analyzed.Results ICU total indwelling central venous catheter 261 cases,34 cases of catheter-related infections occurred,the posi tive rate was 13.03%.The jugular vein catheter 179 cases,positive in 25 cases,the positive rate of 13.97%;subcla vian vein catheter 82 cases,positive in 9 cases,the positive rate of 10.98%.Train a total of 34,of which 21(61.77%) Gram-positive bacteria,Gram-negative bacteria,11(32.35%),fungi,2(5.88%).Conclusion Subclavian venous catheter infection rate is lower than the jugular vein catheter,but by χ2 test(P 0.05) was no significant difference.Age,catheter time,whether invasive monitoring,whether mechanical ventilation and infection by χ2 test(P 0.05),significant difference.Respond to relevant medical staff training,attention to local clean and aseptic,in order to reduce the rate of infection.
