1. 1

   Make sure your tourniquet has been applied properly. Applying a tourniquet increases the amount of blood in the vein to brand them stand up out more. The tourniquet should not be and then tight that information technology cuts off the circulation.^{[2] [3]}

   • The tourniquet should be put on the arm about four inches above the vein.
   • A blood pressure cuff that is inflated to 40–60 mm Hg also works well.

2. 2

   Put a warm pack or water bottle over the area. Warmth will make the patient's veins dilate and expand, making them easier to meet.^[4]

   Utilize proper palpation techniques. Opposite to popular culture, you should palpate the arm, rather than slapping it. Slapping the skin is poor technique that may result in a hematoma. Apply your index finger to look for a vein, which feels soft and spongy. Don't use your thumb, as it contains its own pulse.

   • The warm pack or water bottle should exist put on the area before information technology is disinfected. Zip more than should affect the surface area after information technology is disinfected.
   • Do not apply the warm pack or water canteen directly to the skin. Wrap it in a thin towel to foreclose burns. If it hurts, it is besides hot.

4. 4

   Tell the patient to relax. Many people have needle phobias and nervousness and apprehension is a normal response. Stress not simply makes the veins difficult to hit, but it could also negatively bear upon the test results (particularly for biochemistry panels). Reassure your patient and explain that the pain is very brief and minor.

   • Tell your patient to endeavour visualization and deep animate.
   • Observe your patient and take them lie down on their dorsum if you think they might faint. This will improve the blood menses to their caput. It also reduces their chances of falling and injuring themselves if they exercise laissez passer out.

   Verify patient information. Verify the patient name, appointment of birth and reason for blood draw and cheque the labeling to ensure no mistakes are fabricated. Mislabeling could lead to difficulty processing or fifty-fifty safety issues down the line.

2. ii

   Locate the vein. The within of the elbow is generally the preferred location considering the median cubital vein is usually hands visible. ^[5]

   • The median cubital vein runs between the muscles and may be clearly visible as a bluish bulge in the inside of your elbow. If it cannot be seen it tin usually exist felt. It is too relatively piece of cake to access because the tissue effectually it prevents it from rolling away from the needle.
   • Avert cartoon claret from a identify where your veins split up or join together. Doing and so increases risk of bleeding under the skin.

3. three

   Disinfect the surface area. A mutual disinfectant is 70 pct booze. Wipe an area that is at least two centimeters past two centimeters for at least a half a minute. Later a minute or ii information technology will have dried.^[six]

   • Alcohol is better than iodine considering if the iodine gets into the blood it tin alter values that the lab may be looking for. If y'all do use iodine, follow it with a 70% alcohol swab.
   • Allow the disinfectant to dry out before inserting the needle. Do non blow on or fan information technology with your hand as this will contaminate the area.

4. 4

   Perform the venipuncture. ^[7]

   • Anchor the vein by pulling the skin below the vein taut. This volition forbid the vein from rolling.
   • Insert the needle in at a 15 to xxx degree angle and and then concur it still while collecting blood.
   • Make full the collection tube with blood, following the order of draw as specified by your laboratory.
   • Release the tourniquet after 1 infinitesimal and before removing the needle. Leaving the tourniquet on for longer than a minute will impact the concentration of blood-red blood cells, perchance altering the exam. Withdrawing the needle while the tourniquet is still on will result in hurting.

5. five

   Apply pressure to the puncture area for 5 minutes after the needle is out to stop the bleeding. ^[8]

6. 6

   Dispose of the needle in a hard sided, biohazard container.

7. 7

   Double check the labeling on the tube to make sure information technology is accurate.

1. 1

   Look for another vein if the median cubital vein is non visible. If you cannot discover the vein in the inside of the elbow in either arm, look for another one.^[9]

   • Move downwardly the forearm looking for the basilic vein or cephalic vein. These veins may likewise exist visible through the peel. Take the patient lower their arm and make a fist to make the veins more obvious.
   • The cephalic vein runs along the radial side of the forearm. The basilic vein runs along the ulnar side. The basilic vein is less frequently used than the cephalic. Information technology is more than likely to roll away from the needle than the cephalic vein because it is not held as tightly in place past the tissues around it.
   • If no veins can be accessed, observe the metacarpal veins on the back of the hands. They are usually very visible and tin can be palpated. They should not exist used for elderly patients because the skin is non every bit supple and does non support the veins as well. In improver, the veins themselves go more fragile.

2. two

   Observe sites to avoid. Do not depict blood from areas that:

   • Are near an infection
   • Accept scarring
   • Take a healed burn
   • Are on an arm that is on the aforementioned side as where the patient had a mastectomy or fistula placed
   • Are bruised
   • Are in a higher place an Iv line
   • Are on an arm where the patient has a cannula, fistula, or vascular graft

3. three

   Correct improper needle placement. Occasionally, you may encounter problems with the needle, such as going too far into the tissues or inserting it at besides low of an angle (so the bevel is against the wall of the vein and impedes claret period).^[10]

   • Pull the needle back a little scrap without removing it from the skin.
   • Modify the angle of the needle while it is still under the peel so that it tin can be inserted into the vein.

4. four

   Give up and have a colleague do the procedure if your second attempt fails. Protocol in many laboratories dictates that phlebotomists must effort a venipuncture ii times, and to accept another person practise information technology if both attempts are unsuccessful.^[xi]
