Central venous access device refers to a small, flexible tube positioned in large veins for an individual who needs continuous access to the bloodstream. Such devices are usually considered as catheters or venous access ports, as they permit regular access to the veins without application of deep needle sticks.
All the CVADs require a dressing immediately post insertion of the device to reduce the threat of infection. It requires a dressing surrounding the entrance to the tunnel of the skin unless and until the wound gets healed. This can take about 10 to 14 days based on the condition of the patient.
