Intravenous (IV) cannulation is a technique in which a cannula is placed inside a vein to provide venous access. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products


Sites for IV cannulation
Median antecubital, cephalic and basilic veins

These veins are the preferred sites for insertion of percutaneous central venous catheters.


How do you insert cannulation?

With the bevel of the cannula facing upwards insert the needle (and cannula) into the vein. If there is any sign of swelling, haematoma, pain or resistance the vein wall may be ruptured. The tourniquet must be released and the cannula and needle must be removed immediately and pressure applied with cotton wool.


Complications of gaining I.V. may include infiltration, hematoma, an air embolism, phlebitis, extravascular drug administration, and intraarterial injection. Intraarterial injection is more rare, but as threatening.
