Help Finding right vein for Cannula/Injection vein (with pictures)

[marcy2022]

I had an IV the otherday as sort of a trial and I remember the medical personal failed the first cannula here:

Afterwards they used another vien for the cannula. It was either this one or the one bellow. I think it was the first one. (this is the part I'm not sure, which vein is it?)




I don't have much medical knowledge in any of this but based on my experience with the trial and online videos I'm guessing if done right, both the very first one on the opposite side of palm or the same vein that worked for the 2nd cannula should work again. I just wanted to double check to see if I'm missing anything. On a personal note though, even though the medical professional failed on the vein opposide on the palm, it looks straight enough compared to the other vein that worked. However the person who did the cannula said that my hands and the vien skinny (the one that failed). I was just checking myself and to me the vein that failed and the one that worked are almost the same in terms of thickness but regardless whichever works works. please help.

Avoid extravasation or intra-arterial injection

I thought the marked veins are not arteries, no?

You can tell if it's an artery because you will feel a pulse. Hitting an artery is exceptionally painful.
Vessels around the wrist can be difficult as they're known for rolling.
Usually a drip is administered into the back of the hand or at the centre of the highest point in the hand, with the hand positioned down flat.

You don't need charts. Veins are on the surface of the dorsum of the hand and arm. What can you do to see the veins better?

- avoid dehydration
- high room temperature
- sitting upright
- using a tourniquet
- hitting the vein with the finger

Going by the text and images, the red vessels are arteries

I meant the yellow ones marked with red circles. I should've clarified, sorry!
