Central venous catheter related Infection and risk factors after cardiovascular surgery / 中国综合临床

ABSTRACT

Objective To investigate the pathogen culturing of the catheter related infection(CRI),cathe-ter related bloodstram infection(CRB)and risk factors after central venous catheter(CVC)of cardiovascular surgery in order to provide the beneficial reference.Methods From Jan 2005 to Dec 2005,a total of 300 cases central ve-nous cathers were determined,and the cusp of the catheters was determined by bacteria cultivation,and blood bacte-ria cultivation.Results The infection happened in 35 of 300 patients with inserted central venous catheter.The cusps of CRI rate was 11.7%.CRB rate was 1.7%.54.3%pathogens were gram-positive cocci,34.3% were gram-negative bacilli,11.4% were fungi.The most common strain were Staphylococcus epidermis,Staphylococcus aureus,Klebsiella pneumoniae,Pseudomonas aeruginose,and Candiadia albicans.The infection rate increased obviously when the dwelling time>6 d.Conclusion CRI and CRB are the most severe complication of CVC,and it is important to cut down the death with the early diagnosis and applying antibiotics rationally.
