Although I'd prefer to use sodium nitrite, I don't know if I'll be able to get the antiemetics without a prescription. I've decided to buy a topical numbing cream and try for the femoral artery. The numbing cream I'm looking at has been well-reviewed regarding tattoos. Since I'm cutting deeper though, would it reduce the pain entirely or just from the surface? I'm planning on letting the numbing cream absorb for a couple of hours beforehand.
No that wont work. I dont know what size you are, not that it really matters, but in a slender person the femoral artery is located about an
inch under the skin , but in someone larger, like say a fat person it could be as much as
inches under the skin. I dont believe that you would be able to tolerate the pain long enough to be able to dig in deep enough to get to the femoral artery. The local anaesthetic you are talking about, yes they are great for tattoos, these are fine needles going a couples of millimetres into the skin. The local provides a good barrier of numbness to the outer layer of skin for the person getting the tattoo. So you put the cream on maybe two hours before you go and from the start of when they begin your tattoo you should get about two hours of tattooing before the numbness wears off and the pains starts to kick in. But let me remind you, that there is a big difference between needles going a couple of millimetres into your skin and a knife going into an inch or more? The numbing cream will not be effective at that level im afraid.
