Central venous catheter infection of 521 patients in ICU

OBJECTIVE To analyze the aetiology and risk factors of central venous catheter infections in ICU patients,to explore the prophylaxis and treatment for catheter-related infections.METHODS A total of 521 cases collected from Jan 2000 to Nov 2009 in intensive care unit(ICU) of our hospital were analyzed retrospectively.RESULTS Among 521 cases,209 cases were with positive results of fungi,accounting for 34.93% and G+(29.66%) and G-(35.41%).The positive rates of internal jugular vein and femoral vein catheter were higher than that of subclavian vein catheter.The positive rates of indwelling time for 8-14 days were the highest.The infection rate of common catheter was higher than that of hemodialysis and anti-infection catheter.CONCLUSIONS Central venous cathete infection is related to the catheter type,the indwelling location and time.Fungi and G-are the major pathogens.It is necessary to adopt a series of preventive measures for the catheter infections.
