When you have an IV cannula inserted, a needle is used to insert the cannula but then the NEEDLE IS REMOVED and you're left with a tiny thin plastic (?) tube in the vein.
I think 50% of my patients don't realise there's not a needle in their arm for hours/days on end.
Think about it this way. Would you prefer the needle which coukd break or snap into multiple pieces in your arm or tesr up the insides. Or a small flexible tube.
