Serious harm to the patient can occur if an IVC is placed incorrectly. Letting people place IVC without learning the why behind the skill puts patient safety at risk. IVC placement is difficult for newly licensed technicians. Giving a drug in a catheter that is not patient can cause sloughing of the skin and muscle tissue with certain medications. Not to mention blowing a vein in a critical patient because the person wasn't trained properly is painful for the patient and can make appropriate placement difficult in the future.

Where will the line be drawn? What is to stop untrained staff from placing picc lines or central line? Both are just more difficult IVC placements. An improperly placed or removed picc line or central line can kill a patent. Would you want untrained or uneducated staff placing life saving venous access on your pet? 

The more skills we let untrained employees utilize, the less incentive there is for people to become licensed. We are critically understaffed in this profession. Dissuading people from becoming technicians by allowing unlicensed staff to steal those skills we worked hard for and learned how to do properly weakens the knowledge and confidence clients have in veterinary staff and is a disservice to our patients as well as our licensed technicians.
