TTP Versus the Deep Versus the Shallow, Better Spread With the Deep

I had a TTP done on myself. Oh my. It's pretty good sized artery. I think the arguments I've heard and I've done both. You're going to find this surprising, but I have not found that, especially because I do two blocks on each side. So again, in case people are wondering what on earth are they talking about, we're talking about blocking the anterior cutaneous branches of the intercostal nerves which come off from the sternum.
