For adult patients : 20 gauge
Pediatric patients : 18 gauge
C) Older age or geriatric patients, low prone to blowing a deeper vein :
Older age patients have fragile like thick veins these type of veins easily can
seen in the dorsal part of the hands. You are facing with a fragile vein on an aged client, See for the deeper veins these are more stabilized and less movable.
D) Use a straight vein :
For smooth iv cannulation avoid the insertion of cannula in between two veins venous, in between two veins venous valves are present. If you insert the
cannula in between venous values it will stop the needle from forward and vein side walls will be puncture.
E) If patients arms are cold apply a Hot packs :

Note : If hot pack is not available, you can use warm cloths or providing
warm area.
F) Tell the patient to open and close fist during vein palpation :
Keep the hand downwards and ask the patient arms relaxed and ask patient
closing and opening the fist during vein palpation it will improves the
venous refill and clearly appears.
G) To insert the needle in the vein, use the 15-30 degree angle :
Insert the iv cannula using 15-30 degree angle
H) Avoid the double insertion of cannula insert slowly :
