Selection of vascular access devices and nursing care

To provide an overview of the patient selection criteria for a vascular access device (VAD) and its maintenance care.

The availability of different types of devices had led to confusion on the part of many health care professionals as to which device is the best for their purpose. Selecting the appropriate VAD is an interdisciplinary decision based on patient characteristics, type of therapy, support system availability, and cost. Numerous controversial issues surround the care of VADs, and research results have not yet resolved these practice issues. Although various procedures are used throughout the country, it can be reasonably concluded that the fundamental requirement for successful maintenance of a VAD is strict adherence to established care protocols.

Assessment of the need for a VAD is an ongoing process. Nurses are in a perfect position to assess the factors that precede device selection, including the frequency of access, type of intravenous therapy, and the condition of the patient's peripheral veins. The vast array of devices demands specialized knowledge in selecting the appropriate VAD, providing correct care, and evaluating the device once inserted or implanted.
