I now work in a practice that I’m the only tech. And the assistants are capable to place IVC. They’re seasoned, and trained. It’s honestly not hard to do the motions of placing a catheter.  But still in my heart I just don’t feel right with it.  There’s so much more to IVC than just being able to place it. Education is really important-anatomy, pharmacology, etc.  Now that I’ve come into the practice, I place them. 
Not that these assistants can’t do it and learn. But if something goes wrong, it’s a SERIOUS problem. And that would fall on the DVM in charge. And cause a ruckus. Idk *shrug*. 
Imma LVT yall, step back, I got dis. :)
