Keep the insertion site at or below the level of the heart for a few minutes.The forearm/antecubital fossa tends to be the best options for most people and in most situations. For venipuncture you don’t usually insert the needle very far So you can usually enter the skin just a few millimeters distal to where the vein is visible/palpable.Look for a vein that is clearly visible and/or one that you can palpate with a rubbery/bouncy feedback. DO use a segment of vein that is long enough and large enough to cannulate.AVOID using the flexor portion of the wrist as this site tends to have smaller veins and might be slightly more uncomfortable for patients.These are guidelines, not rules, and there are always exceptions: This is the most important step and takes time and experience. All the other items (labels, more tape, etc) can be collected later.caps off, out of packages, piece of tape cut, etc.) Have everything opened up and ready to grab for ONE HAND use (i.e.Sample collection tubes (laid out in order of draw).Primary needle/blood collection adapter.Collect the immediate supplies that you’ll need right before and after the needle is inserted:.Have supplies easily accessible and on a surface where items can be picked up/put down and kept secure/clean/organized. You often need to do tasks one-handed.You want to be in a comfortable position yourself to improve your chances of success (use a stool, chair, etc.).The patient should be in a comfortable position while keeping the insertion site exposed.During insertion, keep the insertion site below the level of the heart to allow blood to pool into the veins.Treat this like any other complicated procedure: a little time during setup and patient positioning is very important.This will vary greatly with the insertion site, but there are a few basics to keep in mind: Possibly a warm pack if the vein is difficult to find.Antiseptic wipe such as a basic alcohol pad.Can be created/applied after sample collection, but should be available so you aren’t carrying unlabeled specimens after the procedure.The antecubital fossa and dorsum of the hand are very common sites for IV/venous access and so some basic knowledge here might help (although there is variability):īD needle with adapter on the outside for vacuum collection tubes. For children, however, some specific anatomic knowledge is helpful as you may not be able to feel for veins well. Usually for adults, you just need to know if you’ve found a good target, rather than the details of the anatomy. There are many places to start an IV/obtain IV access and a lot of variability in superficial venous anatomy, so no anatomical review will be complete. This isn’t an exhaustive review of anatomy.
