ABSTRACT
Objective To analyze catheter-related bloodstream infections due to Rhizobium radiation (R.radiobacter) in pediatric patients.Methods Clinical data of 1 014 pediatric patients with intravascular catheterization were collected from February 2012 to February 2014,including age,length of time a catheter remained in place,laboratory findings and outcome of R.radiobacter bloodstream infection in order to explore the factors for R.radiobacter infection.Results There were 26 children contracting R.radiobacter bloodstream infection children,and of them,21 were under 2 years old (80.77％),and the length of time for catheter dwelt in vessel longer than 5 days in 20 children (76.92％).There were significant differences in age under 2 years old,length of time longer than 5 days for catheter remained in place,CD4 and CD4/ CD8 between 26 children with R.radiobacter infection and uninfected children (P ＜ 0.01).The re-infection with different varieties of bacterial strains was found in 12 of all R.radiobacter infection children (46.15％) after treatment,and of them,R.radiobacter bloodstream infection was detected twice in 2 children,and 2 died (7.69％).Conclusions Age under 2 years old,the length of time for intra-vascular catheter remained in place longer than 5 days,and weakened immunity are the important risk factors of R.radiobacter bloodstream infection,and the improper medical care may be the cause of re-infections in pediatric patients with prolonged intra-vascular catheter-dwelling.
