Download Article

Drawing blood quickly and cleanly is an important skill for doctors, nurses, lab personnel, or phlebotomists. Many venipunctures are routine, but you may occasionally encounter some hard veins. Read on from step number one beneath for useful information and techniques on hitting those veins.^[1]

1
Make certain your tourniquet has been applied properly. Applying a tourniquet increases the amount of blood in the vein to make them stand out more. The tourniquet should not be so tight that it cuts off the circulation.^[2] ^[3]
- The tourniquet should exist put on the arm about iv inches above the vein.
- A claret pressure cuff that is inflated to 40–sixty mm Hg too works well.

Put a warm pack or h2o bottle over the area. Warmth volition make the patient's veins dilate and expand, making them easier to see.^[4]

iii
Employ proper palpation techniques. Contrary to pop civilisation, you should palpate the arm, rather than slapping information technology. Slapping the pare is poor technique that may outcome in a hematoma. Use your index finger to look for a vein, which feels soft and spongy. Don't use your pollex, as information technology contains its own pulse.
- The warm pack or water canteen should be put on the surface area before it is disinfected. Nothing more should touch the area subsequently it is disinfected.
- Do not utilise the warm pack or water canteen directly to the skin. Wrap it in a thin towel to prevent burns. If it hurts, it is too hot.

2
Locate the vein. The within of the elbow is more often than not the preferred location because the median cubital vein is usually easily visible. ^[5]
- The median cubital vein runs betwixt the muscles and may be conspicuously visible as a bluish burl in the inside of your elbow. If it cannot be seen it can normally exist felt. It is too relatively easy to access because the tissue effectually it prevents it from rolling abroad from the needle.
- Avert cartoon claret from a place where your veins divide or bring together together. Doing so increases risk of bleeding under the skin.
3
Disinfect the expanse. A mutual disinfectant is 70 per centum booze. Wipe an area that is at least ii centimeters by ii centimeters for at to the lowest degree a half a infinitesimal. After a minute or two information technology volition have dried.^[6]
- Alcohol is improve than iodine because if the iodine gets into the blood it can alter values that the lab may exist looking for. If y'all practise utilize iodine, follow it with a 70% booze swab.
- Let the disinfectant to dry earlier inserting the needle. Practice not accident on or fan it with your hand as this will contaminate the area.

Perform the venipuncture. ^[7]
- Ballast the vein past pulling the skin below the vein taut. This will prevent the vein from rolling.
- Insert the needle in at a 15 to 30 caste bending and so hold it still while collecting claret.
- Fill the collection tube with blood, following the order of depict as specified by your laboratory.

Look for some other vein if the median cubital vein is not visible. If y'all cannot find the vein in the within 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 besides be visible through the peel. Have the patient lower their arm and make a fist to brand the veins more obvious.
- The cephalic vein runs along the radial side of the forearm. The basilic vein runs forth the ulnar side. The basilic vein is less ofttimes used than the cephalic. It is more than likely to ringlet away from the needle than the cephalic vein because information technology is not held equally tightly in place by the tissues around it.
- If no veins can exist accessed, find the metacarpal veins on the back of the easily. They are usually very visible and tin be palpated. They should not be used for elderly patients because the pare is not as supple and does non support the veins as well. In addition, the veins themselves go more fragile.
2
Observe sites to avoid. Do not draw blood from areas that:
- Are near an infection
- Accept scarring
- Have a healed burn
- Are on an arm that is on the same side as where the patient had a mastectomy or fistula placed
- Are hobbling
- Are above an IV line
- Are on an arm where the patient has a cannula, fistula, or vascular graft
3
Correct improper needle placement. Occasionally, you may run into bug with the needle, such as going too far into the tissues or inserting it at too low of an angle (so the bevel is confronting the wall of the vein and impedes blood period).^[10]
- Pull the needle dorsum a little fleck without removing information technology from the peel.
- Alter the bending of the needle while it is still nether the pare and then that it can be inserted into the vein.

Give up and take a colleague do the procedure if your 2nd try fails. Protocol in many laboratories dictates that phlebotomists must attempt a venipuncture two times, and to have some other person do it if both attempts are unsuccessful.^[11]
