Protection of indwelling vascular catheters: incidence of bacterial contamination and catheter-related sepsis.
We compared the incidence of catheter contamination and catheter-related sepsis in 200 noninfected patients admitted postoperatively to the surgical ICU. Four methods of catheter fixation were used: (a) povidone-iodine ointment (Betadine) with a sterile gauze and adhesive dressing (Elastoplast); (b) Op-Site film; (c) Op-Site spray followed by Op-Site film; and (d) Beta-dine and Op-Site film. Of 708 catheters used for 200 patients, 516 (72.8%) were cultured. There was no catheter-related septicemia but 13 (2.52%) catheters were contaminated. However, these were evenly distributed among the four groups. We, therefore, conclude that aseptic insertion of catheters, daily inspection of puncture site, and replacement of tubing are the determining factors in preventing catheter-related sepsis.
