Venous Access Devices (cont.)

Exams and Tests

If a central venous access device is present, the health care provider, whether a primary care provider, specialist, or emergency provider, will have a heightened awareness of the problems that can occur. The provider will ask about symptoms and perform a physical examination.

Some of the following tests may be performed:

  • Chest X-ray - Evaluates for improper device placement or complications such as pneumothorax or hemothorax
  • Blood draw - Checks for infection
  • Ultrasound exam of the arm vein - Performed if a clot is suspected
  • Nuclear imaging study - Confirms that the device is properly placed and still working and/or excludes blood clots in the lungs

Follow-up

The venous access device can be removed when it is no longer needed, such as when the medical problem for which it was inserted has resolved.

Proper home care of a venous access device involves regular irrigation with a drug called heparin to prevent clotting (except with Groshong-type catheters) and attention to a sterile technique to keep the device free of infection.

  • The person with the venous access device and a caregiver will be shown how to care for the device.
  • Supplies will be provided or an explanation will be given for how to obtain supplies.
  • Instructions will be provided in other ways to prevent problems with the device.
  • In some cases, a home health agency can bring the supplies needed and provide support as the individual learns how the care for the device.

Follow any instructions given by the health care provider or nurse to care for a venous access device at home.

  • Avoid heavy exertion or strenuous activity immediately after device placement.
  • Change the bandages as directed.
  • Inject heparin to keep the device working as directed.
