Forty-seven patients were admitted to National Center for Bone Marrow Transplantation — CEMO in Rio de Janeiro. Fifty-seven Hickman-Broviac catheters were inserted by venous access. The mean duration of catheterization was 38days (range, 1-209days) fora total of 3104 catheter-days. Twenty-eight catheters (49.1 %) were removed after catheter-related infections; infection rate was 42.1 % and mortality rate 4.2%. After modification to a weekly catheter care and heparinization program assisted by nursing staff, the initial infection rate (45.2%) dropped to 20 % for the last 15 catheters evaluated. Neutropenia was nota risk factor for the development of sepsis related to the catheter. Gram-negative organisms were the predominant etiologic agents isolated during the infectious episodes (52 %). Enterobacter sp. and S. epidermidis were isolated with equal frequency and represented 48% of the isolates. Six microorganisms (24 %) were resistant to antibioties used during the infectious episodes. Four gram-negative organisms were resistant to amikacin and two, gram-positive, were resistant to oxacillin.
