Popis: | Objective : To evaluate in vitro and in vivo the efficacy of covalent end point-attached heparin to single-lumen polyurethane central venous catheters in reducing microbial adherence and colonization. Design : In vitro study : A controlled bench study. In vivo study : A prospective, randomized, double-blind, clinical trial. Setting : Intensive care unit in a 1200-bed teaching hospital. Interventions : In vitro study : Adhesion of 17 radiolabeled clinical isolates of Staphylococci to catheters was examined in vitro. In vivo study : The outcome of heparinized and control catheters was compared in vivo in patients receiving long-term parenteral nutrition. Fifty-five adult patients were prospectively, blindly randomized to heparinized or control central venous catheters. The catheters, removed on clinical grounds, were analyzed with semiquantitative and quantitative cultures. Blood cultures were done at catheter removal. Measurements and Main Results : In vitro study : Coagulase-negative Staphylococci adhered less in vitro to heparinized catheters than to control catheters (p |
