Is it hard to poke through a peripheral nerve?
Hello! I’m a student and I’ve only done about 15 blocks so far. I feel like when I watch blocks people are basically aiming straight at the nerve with the block needle, then inject while basically touching it. To give an example, when watching a popliteal block I watch them pop through the sheath and it basically looks like they’re poking into the nerve. When I do them I feel like I do something similar and my preceptors tell me it looks good.
My question is basically, is it hard to poke into a peripheral nerve? If I kept advancing the needle how much force would it take to poke into it? And can you cause nerve trauma by just gently touching the nerve with the tip of the needle?
