Q. Should IV Cannula be preferred over needle?

Answer

IV cannula is especially good when a patient is undergoing prolonged treatment and needs regular medications invasive method for some days or may be months. The IV cannula is fixed in a vein and taped to the hands so that it remains firm at the place causing no pain to the patient. Multiple times the medication can be delivered through IV cannula in comparison to a needle which needs to be inserted every time the medicine is to be delivered.
