A recent audit highlighted some adhesive dressings are being applied incorrectly to cannula sites, and bandages are being used when tube dressings are recommended. Read on as to why it's important to get this right.

Some dressings obscured the insertion site which meant colleagues couldn't observe the site for problems . And some left the insertion site uncovered and open to potential contamination.

The audit found bandages are being used to secure difficult cannula sites rather than the recommended tube type dressing. 

It's important to remember bandages applied too tightly can restrict flow and cause discomfort.

To assess the insertion site adequately, a bandage needs removing and then replacing each time, and this may well contribute to Visual Infusion Phlebitis (VIP) scores not being completed appropriately.

The Peripheral Venous Cannula Policy states:

"Bandages should not be used to cover peripheral venous cannula. However, covering a cannula may prevent dislodgement in certain paediatric patients and patients who are for example confused. If covering the cannula is essential, it should be a tubular type stockinette such as tubifast, ensuring blood flow is not compromised. This should be cut to size and removed to observe the insertion site enabling staff to complete the PVC documentation".
