[Bacteriological analysis of the risk of contamination in the catheter package for intravenous hyperalimentation--the frequency of catheter package exchange for IVH].

The all-in-one catheter package for intravenous hyperalimentation provided an easy handling to the medical staff. However, the package is the cause for a medical cost increase. In order to reduce the medical cost, the incidence of bacterial contamination on the catheter was compared between the two groups: one group is to exchange the catheter once a week and the other is to exchange the catheter twice a week. No bacterial contamination was found in both groups. The result suggested that once a week catheter exchange was tolerable against bacterial contamination.
