Dressing changes by specialized personnel reduce infection rates in patients receiving central venous parenteral nutrition.

In 60 pediatric patients, 75 central venous catheters representing 1866 patient days were placed to provide parenteral nutrition. During the 21-month study period, surgical residents were responsible for dressing changes during the first 16 months and a specially trained nurse was responsible during the final 5 months. Twenty percent of the lines became infected. The infection rate was significantly higher in the lines cared for by residents, 28.8% compared to 3.3% in the lines cared for by the nurse. This occurred in spite of the lines being in place significantly longer in the nurse group (31.7 vs 20.3 patient days/line). These data indicate that a specially trained person using aseptic techniques can reduce infection rates in patients receiving central venous parenteral nutrition.
