Hajer... I just graduated and I haven't started a successful IV either (haven't had many tries though)
I too don't like the thought of causing pain..IVs definitely hurt

But our patients need these IVs for life saving treatment. Sometimes medical treatment means we have to cause pain for the greater good to the patient. Remember all new nurses had to learn this skill!
Personally for me...knowing that it IS a painful procedure... I want to really perfect this skill over time. To do that I'm going to need a LOT of practice. Unfortunately you can only get that practice by doing it again and again. Watch some other nurses and learn their tips and techniques. Then volunteer to do everyone's IV starts! And have other nurses watch you and provide feedback for improving your skill. The hardest part I "think" anyway is finding a good vein. Try and not be nervous (I'm telling myself this too! lol) and take your time finding a good site and having all your materials ready. That way we can set ourselves up for being successful and hopefully getting it on the first try so that we reduce the trauma to the patient. Over time and with persistance and help from other nurses I believe we can all get this skill down! You can do it! I can do it!
