Avoiding contamination of CVADs when bathing and showering
Nicola York, Nicki Angell-Barrick, Jo Carter, Maya Aquino-Guerrero
Journal of Kidney Care ,Vol. 5, No. 2,
30-03-2020
Overview
Delivery of dialysis through a tunnelled central venous access device (CVAD) is associated with a high risk of infection, when compared with other routes. The risk of contamination increases when the catheter dressing becomes wet, for example, when the patient is showering. Entry of the bacteria into the blood stream can result in a systemic infection. Protection pouches can be used to avoid this risk.
