  • Title: Catheter-related colonization associated with percutaneous inserted central catheters.
    Author: Pauley SY, Vallande NC, Riley EN, Jenner NM, Gulbinas DG.
    Journal: J Intraven Nurs; 1993; 16(1):50-4. PubMed ID: 8437046.
    Abstract:
    The intravenous therapy team at Massachusetts General Hospital studied the potential infectious risks of maintaining percutaneous inserted central catheters (PICC) for prolonged periods. Cultures of 100 PICC sites and catheters were performed on removal of the catheters, which had remained in place for 2 to 43 days. The insertion sites and/or proximal or distal segments of the catheters were found to be colonized in 11% of the patients, with distal catheter tips significantly colonized in only four patients. Nine of the patients were colonized at the insertion site. Bacteremia did not occur as a result of the extended dwell time of the catheters.
