Assessment for Catheter Function, Dressing Adherence and Device Necessity

Abstract

Vascular access devices (VADs) such as peripheral intravenous vascular catheters (PIVCs), peripherally inserted central catheters (PICCs) and central venous catheters (CVCs) are essential and common components of modern healthcare practice. In the USA, over 1.4 billion vascular access device procedures are undertaken annually, whilst in the UK, one in three patients will have at least one cannula inserted during their hospital stay. Such devices deliver a myriad of treatments ranging from fluid replacement and delivery of medications to laboratory blood sampling. However, these devices are not without their unwanted complications including phlebitis, thrombosis, dislodgement and bloodstream infections, some of which have the potential to be life threatening. Great emphasis has been placed on the insertion of these devices in reducing their potential risks. However, the right maintenance and care of these devices is equally important and is the focus of this chapter.
