Résumé
Objective To study the factors related to the infection induced by internal jugular catheterization and femoral vein catheterization.Methods Bacterial culture was conducted for samples collected from the outer section of catheters,the skin around the catheters and the puncture sites during different stages of the catheterization as well as the cathetor blood before removal and the catheter tips after removal in 75 cages after deep vein catheterization from March to August,2008.Statistic analysis was made on positive results.Results The positive rate of the bacterial culture in femoral vein group was obviously higher than the internal jugular group.Rank correlation analysis indicated:the positive rate of the bacterial culture for the puncture site was highly correlated with that for the outer section of the catheters and the skin around the catheters;and the catheter blood(at the tip)was in low positive correlation with that ofthe puncture site and the skin around catheters.And the positive rate apparently rose on the 3～7th days after the catheterization.Conclusions The catheter-related infection after CVC was closely correlated with the outer section of the catheters,the bacterial pollution to the akin around the catheters and different stages of the catheterization in addition to catheterizing location.It is suggested that nurses should choose proper catheterizing position according to different purposes while paying attention to the nursing work for the puncturing part and during the stage with hish risk of infection so as to reduce the occurrence of catheter-related infection.
