[QUOTE="Texan, post: 62037, member: 416"] It's not really that difficult, but it might seem like it until you get the hang of it. I find it's easier and quicker with vacuutainers than syringes, but that may just be personal preference. I'll [i]try[/i] to describe it for you since nobody else has taken a shot at your question. Keep in mind that it is one of those procedures that is much easier to show than tell. ;-) Lift the tail up so that you can access the underside. In the center of the underside of the tail, you will find what feels like a soft groove with bone or cartilage on either side of it. This groove runs down the length of the tail, getting smaller as you get closer to the end. It will feel similar to the soft area between your knuckles, with a vein running in the soft area, just as in your knuckles. The closer you get to the tailhead, the larger it is, therefore the easier it is to hit. Once you get through the skin with your needle, put some vaccum to it and you should be able to tell when you hit the vein. If your needle bottoms out, withdraw it [i]slightly[/i] until you come back through the vein. It's not real big, so it will take a steady hand to stay in it. Remember that the closer to the tailhead you try, the easier it is to hit and stay in. If you do it often, you will find it relatively quick and easy. If you don't keep in practice, you will probably find it slower than neck bleeding. [/QUOTE]
