Analysis of central venous catheter related sepsis / 肠外与肠内营养

ABSTRACT

Objectives: To investigate the distribution of common pathogens and their antibiotic resistance from patiens with catheter related sepsis (CRS).Methods: Catheter bacteria cultrure and antibiotic sensitivity test were performed from 69 patiens with CRS.Results: The common pathogens in CRS were fungi (41.1%),Gram-positive cocci (35.6%)and Gram-negtive bacilli (23.3%). Non-C. albicans species were major pathogen (19/30 stranins).The most strains were staphylococcus epidermidis in Gram-positive cocci and the most of them were Methicillin resistant.No vancomycin resistant strains were found. The Gram negative bacilli were often resistant to third generation cephalosporens.Conclusions: The dorminant pathogens of CRS are fungi and gram positive cocci and we should pay more attention to pathogens of resistence to antibiotics. In order to control CRS, CVC must be used reasonably and shorten the duration of retention.
