Best Veins for Venipuncture (IV Insertion, Drawing Blood, etc.) for Nursing, Phlebotomy, EMTs, etc. As a nurse, phlebotomist, or other healthcare professional, you'll need to find veins for various venipuncture procedures, such as starting IVs or drawing blood. There are certain veins that tend to work well for this procedure, and other veins that tend to cause problems. In this video, I cover some of the best veins for starting IVs or drawing blood. As a nurse, it is important to learn the location of major veins in the arm and hands, as a common nursing skill is inserting IVs and drawing blood. Some of the best and most common veins include the median cubital vein, accessory cephalic vein, median antebrachial vein (median vein of the forearm), and the dorsal venous network. I not only demonstrate the location of those veins, but I also include tips such as the needle gauge size that most of those veins can handle (which can vary in adults), as well as some tips on how to stabilize veins when performing venipuncture procedures.
