A prospective, randomized, controlled trial comparing transparent polyurethane and hydrocolloid dressings for central venous catheters

摘要

Background: This study was under taken to determine the frequency of skin colonization, hub colonization, and central venous catheter colonization in transparent hydrocolloid versus standard polyurethane dressings. Methods: Adult patients requiring the insertion of a multilumen central venous catheter in an intensive care unit were randomized to receive wither a Standard polyurethane dressing or a transparent hydrocolloid dressing. Cultures were obtained from 125 skin insertion sites, 141 catheter hubs, 128 Catheter tips, and blood samples form 132 patients. Extensive data on patient and catheter characteristics were collected.
