Central venous access devicesIntroductionSome of the treatment you require will need to be given directly intoyour bloodstream. In order to do this, we will place a device intoyour vein, called a venous access device. This enables us to haveaccess to your venous system to give your therapy.There are several different types of devices available. One type iscalled a peripheral cannula. It is a small plastic tube that is insertedinto a vein in your lower arm or hand, through a needle. This needleis then removed, leaving the cannula in place for a few hours or upto three days while you have treatment. We will remove the cannulawhen you finish treatment. You will be given a new cannula everytime you need treatment.Sometimes, this can affect the veins and make it harder to insert thecannula into a vein. If this happens it may be suggested that youhave a central venous access device put in instead. Some treatmentdrugs cannot be given into the veins of the hand or the arm and canonly be given, through a central venous access device, into a largervein leading to your heart.What is a central venous access device (CVAD)?A central venous access device (CVAD) is made of a non-irritantmaterial, for example, silicone, which means it can be left in placefor several weeks or months. The CVAD may contain one or twotubes. When a CVAD contains two tubes, it is called a double ordual lumen catheter.What are the advantages of having a central venousaccess device?Whatever the type of CVAD, it can be used to give you fluids anddrugs. It may also be used to take blood samples. The CVAD willsave you or your child from having repeated needle pricks fromblood taking or insertion of cannulas during treatment.1
