How To: Draw venous blood samples from the antecubital veins

Draw venous blood samples from the antecubital veins

This step-by-step video will show the proper technique of phlebotomy, which means drawing a sample of venous blood. Everyday, nurses take blood cultures from hospitalized patients, so standard tests can be run for diagnosing conditions and diseases. Venipuncture is necessary for obtaining the blood sample.

These are great instructions for nursing students, for preparation into life in hospital care. The most frequent sites for sampling blood are the larger and fuller median cubital and cephalic veins of the arm. The wrist and hand veins are also acceptable.

The equipment you will need is: protective eyewear, protective gloves, the necessary blood collection tubes (blood culture tubes), tourniquet, provodine-iodine solution, an alcohol swab, a piece of 2x2 sterile gauze, a Vacutainer needle (#20), a Vacutainer syringe, and a piece of tape to secure the gauze.

This video on the phlebotomy procedure was produced as part of the Common Currency project at the Dalhousie University Faculty of Medicine. There might be slight variation of the procedure from institution to institution depending on policy and equipment used.

Wow! Who approved this video for publication?! There are SO many things wrong with that draw I don't even know where to begin! (1) incorrect cleansing w/ alcohol pad (2) touching the site after it's been cleaned, (3) needle angle, (4) not letting the alcohol air dry before needle insertion, (5) contaminated specimen due to either touching site after it's been cleansed or wet alcohol causing hemolysis of the RBCs, (6) not mixing the tubes (a SURE reject in the lab), (7) not removing tube before withdrawing needle from arm, (8) pressing cotton ball into arm before needle is withdrawn, (9) not checking to see if bleeding has stopped completely before bandaging arm, (10)..11...12...13... That's enough.
