Central venous catheters: choosing the most appropriate access route.

Abstract

Intravenous therapy and care is a complex and intricate area of practice, which is being subsumed into the core role of registered nurses. As more patients become recipients of a vascular access device (VAD), particularly those requiring intermediate to long-term central venous access, it is important to ensure that not only the device but also the most appropriate vein meets their clinical physiological and psychological needs. There is much research and literature on the insertion and care of central venous catheters (CVCs) as well as the detection and treatment of complications. However, apart from a few small studies comparing the performance of devices placed either in the subclavian or jugular veins, there is little to guide doctors or nurses as to which vein is preferable, if secondary complications are to be avoided. This article will describe a number of primary and secondary complications associated with both the subclavian and internal jugular veins and how these can be minimized by selecting the most appropriate vessel. The article concludes with the author's suggestions for correct patient assessment in order that the correct vein is utilized.
