Matt, CRNA's most definitely place central lines, pa catheters, a-lines etc. I will admit that there are hospitals that try to restrict this practice. It has been my experience that it is mainly the anesthesiologist trying to seperate themselves from the CRNA. To prove to others they posses some skill that we don't. When applying to anesthesia school, make sure you interview the school as well. Get a good idea of whether or not they are going to provide you with adequate training in that area. When I graduated from anesthesia school, I walked into my first job with ample skill to place central lines, arterial lines etc.. These are technical skills that do not take a medical degree to learn. In fact PA's often place these types of lines as well.
