Yep, but more . There are risks involved with doing an EJ like introduction of air directly into the cardiac circulation, causing pneumothorax and so on. They can be tricky to get sometimes, depending on the patient's anatomy.
I prefer a 16g or 14g short cannula as I find that the long needles can be difficult to manipulate as you often don't have much room to move. Putting a bend in the cannula can make it easier to get in, but you have to be careful that it doesn't make it difficult to feed off the catheter once you are in.
Pretty much the same as any other vein. Most pts only require standard pressure by finger for a minute, others require a good pinch for several minutes. Other than a few blown veins over the years, I have not had any other complications personally since I started in the 80's. So I don't have anything to report other than what you can get from books and what "Smash" has said.
The EJ has been a #1 gaurentee in codes. The venous pooling really make that thing stand up beautifully.
As a rule of thumb, if you blow one side... you generally do not get another chance, and you don't hit the other side..
