Q. How IV Cannula is useful?

Answer

IV cannula is very useful as it eliminates the need for frequent insertion of needles in the body. For delivering medications on a regular basis for some days, the IV cannula is fixed to a vein and then delivered timely medications through the opening in the cannula. If a patient needs saline or fluid for instant relief, say, from diarrhoea or weakness due to loss of body fluid, IV cannula enables delivery from a bottle or vial. It is also very useful in supplying blood to a patient’s body in case of loss of blood.
