Is routine changing of peripheral arterial catheters justified?

Abstract

Although peripheral arterial catheters (pACs) are used extensively, disagreement persists concerning the practice of scheduled replacement to prevent catheter-related infections. Despite recommendations and no proof of benefit, pAC replacement continues to be scheduled as a routine practice in many intensive care units (ICUs) worldwide. Our own experience in an oncology ICU, based on a 217-device database, confirms that the risk for pAC-related infections is stable over time, arguing against scheduled replacement. The low rate and stability of the risk of pAC-related infections supports the rationale for conservative management in accordance with expert recommendations. © 2008 European Society of Clinical Microbiology and Infectious Diseases.
