Intravenous access: related problems in oncology

This article reviews the latest developments in the literature concerning two types of catheter widely used in oncology: Hickman central venous catheters (CVCs) and totally implanted venous ports. It now seems possible to diagnose catheter-related bloodstream infections (CRBI) without removing the device; recent studies showed that paired quantitative blood cultures are the most reliable and convenient method for diagnosis of CRBI. Can CRBI be cured and treated without device removal? A decision-tree/flow-chart resulting from analysis of international data by French International Experts is presented. Futures trends are reviewed: new techniques for prevention, including catheters impregnated with antimicrobials and, antiseptic hubs; flushing and antibiotic lock techniques that can be used both for prevention and treatment.
