To achieve satisfactory result, a moderate pressure (60 mm Hg) for a less than a minute is enough to suitably dilate the vein, avoiding the risk of inducing excessive venous stasis that can alter haematological and biochemical parameters. Clin Lab. The median cubital vein, a superficial vein that forms a connection point between the cephalic and basilic veins of the arm is large, and therefore easier to see and feel. Collecting and Processing of Specimens A. The blood collects into an airtight vial or tube attached to the needle. In this regard, the needle bore size, and in turn the gauge, may be regarded as a reliable predictor of haemolysis, with 21 G needles showing half the risk of producing an unsuitable sample respect to 23 G 13).

The MCBV also passed above the lateral cutaneous nerve forearm (LCNF) in 8 of 128 cases (6.2%). Venipuncture is a multi-step procedure that poses risk to the phlebotomist. Very recently it has been shown that changing the position from sitting to lying (and vice versa) causes a significant bias in several laboratory values, due to the gravitational adaptation which changes the hydrostatic pressure along the various body districts 23). After palpating the path of the vein, clean the venipuncture site with alcohol using a circular motion. In some cases, your health care provider will tell you if you need to stop taking any medicines before you have this test or if you need to be fasting.

Hemolysis can be readily detected by visual inspection after sample centrifugation, and directly quantified through a spectrophotometric reading even at low concentration. However some authors have reported that the use of winged needles may contribute to lower the risk of nerve injury at the upper limb site 36). Define venipuncture. The cephalic vein is more commonly accessed on the forearm rather than the upper arm. When the veins become engorged for easier visualization, the health care provider will select the best site, prior to entering the needle for collecting a specimen, or subsequently inserting an IV catheter to establish a line. Establish Blood Flow, Release Tourniquet, and Ask Patient to Release or Open Fist 12. The ideal sites for venipuncture are typically in the cubital fossa of the forearm, which has the shape of an isosceles triangle with the biceps forming the base, and the lateral and medial groups of the antebrachial muscles forming the sides respectively 26).. What are the common sites for venipuncture? Review the important aspects of your blood collection procedures, including the recommended order of draw, proper patient identification, acceptable and unacceptable sites for blood collection, and variables in collection procedures that can affect the accuracy of the blood test. 8. At the elbow, the cephalic and basilic veins are connected by the median cubital vein, which crosses the roof of the cubital fossa. In this regard, the use of bar coding test tubes, along with the adoption of educational programs which helped to increase the compliance of the operators to the best practice guidelines, resulted successful in lowering the rate of unsuitable samples 21). Venipuncture Sites. 2002;95:1218–20. CLSI document H3-A5. It helps control body temperature, fluid balance, and the body’s acid-base balance. Diaphoresis with hypotension occurred in 2.6%. 2.

Sodium citrate blood contamination by K2 -ethylenediaminetetraacetic acid (EDTA):impact on routine coagulation testing. 2012;58:911–7. However, veins at this site have a greater mobility due to the poor surrounding connective tissue, and thus they more easily “roll” under the needle’s tip or collapse, causing a missed attempt or a rupture of the vessel. Dermatol Surg. Although the color-code scheme was devised to help the operator in recognizing the additive within the tube, the broad heterogeneity in the scheme adopted by the various manufacturers and the lack of standardization resulted in a serious issue 22). 13. J Fam Pract. Biochem Med. Sometimes, neither tourniquet nor tapping is effective. Biochem Med (Zagreb). 2002 Jun; 20(6):402-3. above venipuncture site.

Cleanse the site thoroughly. However, for whole blood samples, haemolysis can be neither observed nor directly measured. Page 1 of 8 Specimen Collection – Venipuncture Procedure I. Allow to air dry. Biopreserv Biobank. Specifically, these veins are the median cubital vein, the cephalic vein, and the basilic vein.The main idea behind venipuncture is to draw blood for any number of diagnostic tests. Notably, it is important to know the spatial relationship between the path of veins and cutaneous nerves that can be accidentally pinched during needle insertion, causing intense pain and nerve damage 30). Clin Biochem. 8.5). Blood-draw; Phlebotomy. The cephalic vein is more commonly accessed on the forearm rather than the upper arm. However this is a very rare consequence occurring in about 1: 25,000 individuals undergoing blood donation 34). Since potassium is mainly intracellular, a false elevation in its blood level can be easily achieved through various processes. The needle should not rest against the upper wall of the vein or puncture through the vein wall on the opposite side. Serum is the fluid part that remains after the blood is allowed to clot in a test tube. A bandage may be placed over the area if there is any bleeding. Specifically, these veins are the median cubital vein, the cephalic vein, and the basilic vein. C. Basilic vein. Venipuncture may also be done to remove extra red blood cells from the blood, to treat certain blood disorders. Learn. Cleanse the site thoroughly. Minor bruising and hematoma (blood clot under skin) were fairly common, involving 12.3% of venipunctures, with minor bruising being the most common reaction 48). Reducing preanalytical laboratory sample errors through educational and technological interventions. 12. To begin, the animal should be properly restrained (Fig. Allow the area to dry. Based in Chicago, Jojo Genden is passionate about sharing her health and wellness expertise through writing since 2008. 2012;136:352. However, it should be noted that drawing an EDTA tube after all the others physically prevents any possible contamination, regardless of the way the system is used as already mentioned in this paper. See below. The most common nerve injury related to venipuncture involves the lateral antebrachial cutaneous nerve (LACN), which can lead to the so-called “causalgia” or complex regional pain syndrome 32). Anat Sci Int. 2015;48:62–5. Written on: July 14, 2020. syringe image by NatUlrich from Fotolia.com. Apply the tourniquet and do not repalpate the cleaned skin. Cattle tend to resist venipuncture, and it should never be attempted on an unrestrained animal. Genden is a registered nurse in the state of Illinois with a background in intensive care. Although in the large part of individuals the running pattern of superficial veins appears well evident in this region, the path and distribution can be irregular and may require a careful inspection before attempting the needle insertion. Ernst DJ, Ernst C. Home Healthc Nurse. Complications occurring from diagnostic venipuncture. The site is cleaned with germ-killing medicine (antiseptic). Lastly, the body positioning, which is a fundamental but often overlooked factor in laboratory preanalytics. Although not strictly related with the procedure of phlebotomy, there are some other issues which deserve a discussion, as they are among the most frequent causes of pre-analytical errors 19).
