Greetings and welcome to justanswer,
Why you want to start the iv line?
did you consult a doctor/nurse yet?
do you suffer from kidney disease?
The peripheral iv cannula is usually avoided due to the av fistula which has direct arterial access to the heart.
Any contamination with bacteria may reach the heart then brain and to other vital body organs quickly if it is in the arterial line.
In such patients when the vein is not accessible then the venous femoral sheath/brachial or central venous line (subclavian or internal jugular) is used.
Let me know if you have any doubt.
