title: [Advantages of routine periodic replacement of the central endovenous catheter in total parenteral nutrition].
abstract: OBJECTIVE
  To determine the utility of rutinary periodic replacement catheter of total parenteral nutrition (TPN) to prevent the incidence of catheter-related infection.
  
  
  METHODS
  Cancer patients admitted between Jan. 1, 1996 and Dec. 31, 1997, to receive TNP, were eligible for enrollment in the study. Placed a chateter of poliuretane with double lumen each patient for Nutrition Department. Replacement catheters done over a guidewire after ten days, with or without infection sings. Rates of catheter-related infection were documented for de novo, and guidewire exchanged catheters and analyzed relative risk for infection.
  
  
  RESULTS
  Twenty catheter-related infections developed in 140 patients. When the rate of catheter-associated infection was determined for each type of catheterization, the replacement catheter had a high observed rate of infection than either de novo type (19.5% vs 7.8%; p = 0.027). We found that the risk of developing a catheter-related infection in a de novo catheter was significantly less (p < 0.01).
