Why do we get blood taken mainly in the ditches of our arms?
In: 10
A couple of reasons:
1. Consistent anatomy between patients. Most patients will have pretty much the same anatomy with the major veins their. The basilic, brachial, cephalic and median cubical veins are in very similar positions on most people where’s other veins are much more varied between people.
In people with very difficult veins you can even sometimes just get lucky even if you can’t see or feel it just based on the consistency of the anatomy.
2. They’re close to the skin and wide.
3. It’s hard to hit an artery as they’re generally quite deep in the arm away from the veins
4. Hurts less than other places. I’ve had to take it from feet before and I was very unpopular afterwards.
5. Easily accessible.
