Peripheral Venous Access
Peripheral Venous Access means infusing factor into a peripheral vein. Peripheral veins are located away from the central part of the body, such as in your hands or arms. A single needle is used, then thrown away after each treatment, so nothing remains under the skin (if you are using a butterfly needle).
According to the Consensus Recommendations, peripheral venous access is strongly encouraged whenever possible.1 With peripheral access, there is reduced risk of infection and other complications, plus fewer limitations on lifestyle and activities. While CVADs have some advantages – primarily fewer sticks and easier access to veins – it is important to remember that CVADs are not a permanent solution and that peripheral access is the long term goal and solution.
Two types of devices may be used for peripheral venous access.
- Butterfly needle — This type of needle, with tubing attached, is used once, then discarded. The "wings" make handling the needle easier. The factor is given through the needle and tubing after it is secured in the vein. Then the needle is removed and thrown away.
- Heparin lock or saline lock — These devices are used to access a vein for a few days. A small flexible plastic tube is inserted into a peripheral vein. A plastic cap is then placed on the other end of the catheter. It is usually inserted by a healthcare professional for use at home.
There are a number of peripheral veins that may be used for venous access. Common locations include hands and arms2, although veins in the feet and head may also be used. Your healthcare professional can help you determine which veins will be easiest to use.
