Analyzing etiology of central venous catheter related infections and risk factor in emergency intensive care unit / 中国医师进修杂志

ABSTRACT

Objective To investigate the feature of pathogenic bacteria in central venous catheter related infection (CVC-RI)and risk factor in the emergency intensive care unit (ICU).Methods One hundred and three patients were checked out bacteria from January 2006 to December 2008 in the ICU who were central venous catheter and corresponded with diagnostic criteria for CVC-RI.They were analyzed retrospectively.Results The ratio between Gram-postive bacteria (37.9%,39/103)and Gram-negative bacteria (42.7%,44/103)were not statistically significant,however,CVC-RI was related to applying duetal number,duct keeping on time and elect location.Duct staying in subclavian vein had the fewest chance.Conclusions It would be better to choose duct staying in subclavian vein.control remaining time and luminal number,and monitor changing pathogenic bacteria strictly.Main measures are taken to evade the pollution on the ental and external lumina.
