[Care of skin infections in patients in peritoneal dialysis]

The incidence of exit-site infections among peritoneal home-dialysis patients was quantified following for 1 year all home dialysis patients of 23 dialysis centres. The exit site conditions were observed and classified according to Twardowsky. When an infection occurred data on its treatment were collected. 393 patients were observed. The infection occurred in 40 patients (10.1%). 82.2% of patients wear a Tenckoff catheter, 3% do not protect the exit site with any kind of dressing. The strategies adopted by different centres vary for the choice of antiseptics, the suggested frequency of changes dressing and the routine use of nasal swabs. Due to the limited number of patients with infection no association was found between tunnel direction or frequency of dressing changes and infections occurrence. Discussion on controversial aspects and the definition of common guidelines for instance for frequency of dressing changes, use of antiseptics is warranted.
