Download PDF, 1.27MB, PDF

What Is an Intravenous (IV) Cannula?

An IV cannula is a small, short piece of plastic tube. It is inserted into a vein, usually in the hand or arm by a trained healthcare professional, to receive intravenous medications or fluids.

An extension tubing will be attached to the cannula along with a transparent dressing to secure the cannula.

The cannula will be covered with a bandage for extra protection. The bandage dressing will be changed at each clinic visit.

How Often Do I Need to Change My Cannula?

  • Every 72 hours
  • When the cannula is blocked or has slipped out of position (dislodged)

How Do I Care for My Cannula at Home?

  • Remove the dressing
  • Pull the cannula out

  • Submerge the cannula site in water, such as bathtub or swimming pool

What Should I Do If I Face Problems with My Cannula?

If the cannula is dislodged,
