Evaluation on laboratory diagnosis of catheter-related bloodstream infec-tion due to Rhizobium radiobacter in pediatric patients / 中国感染控制杂志

ABSTRACT

Objective To evaluate diagnostic method and infection factors for catheter-related bloodstream infec-tion(CRBSI)due to Rhizobium radiobacter (R.radiobacter)in pediatric patients.Methods Clinical data of 1 014 pediatric patients with central venous catheter(CVC)-related treatment in a hospital from February 2012 to February 2014 were collected,semi-quantitative culturing of catheter,colony forming unit (CFU)ratio of catheter to venous blood,difference in culture time between venous blood and catheter were detected among patients with R.radiobact-er infection;factors for R.radiobacter infection were analyzed.Results Of 1 014 pediatric patients who used CVC, 32 were detected R.radiobacter from catheter blood,28 were detected from venous blood,27 were detected from both catheter and venous blood.Catheter semi-quantitative culture of 27 patients were ≥ 15 CFU,5 were5 days are risk factors for R.radiobacter bloodstream infection.
