occay, here is the thing
for doctors , intravenous injection supposed to be a simple task as it is something we do everyday.
hence, we are good at it. ( we are not talking about houseman here - housemen are new doctors who are still learning , hence they may not be as good in doing this - no offence )
anyway , there are rules to follow when doing intravenous injection. u need to follow these rules to avoid any undesirable complication.
firstly , the site of injection. the best site of intravenous injection would be the cubital area. nevertheless in some cases , the vein is not visible - hence the experience of a doctor is needed here to find the visible vein.
when the vein is located , tourniquet is applied to stop to blood flow at the area , then the site is sterilized using alcohol swab.
selection of correct needle size and syringe size is crucial in order not to damage the vein. Too big , u will destroy the vein , too small , it will be difficult to administered drugs into the vein.
the most crucial part is when injecting the drug into the vein. if u doing it straight from the syringe n needle into the vein - without the help of branula or butterfly ... u must have a very steady hand to make sure that the needle will not slip from inside the vein . a little movement could make the needle slips outside the vein , and that will cause a lot of pain and swelling....
occay , that is pretty much the rules u have to follow , the correct way of intravenous injection
sound easy isnt it?
