Drawing blood, also known as venipuncture, is a medical procedure in which a needle is used to extract a sample of blood from a vein.

The following steps outline the basic procedure for drawing blood:

• Gather equipment: You will need gloves, an alcohol swab, a tourniquet, a needle, a vacutainer.
• Identify the appropriate vein: Look for a vein that is visible, easily accessible, and free of any apparent abnormalities.
• Clean the area: Use an antiseptic (alcohol swab) to clean the area where the needle will be inserted. This helps to reduce the risk of infection.
• Apply the tourniquet: Wrap a tourniquet around the upper arm to make the veins more visible and easier to access.
• Hold the skin taut: Use your free hand to gently but firmly hold the skin over the vein. This will help to prevent the needle from moving or slipping during the procedure.
• Insert the needle: Using a quick, smooth motion, insert the needle into the vein at a 15- to 30-degree angle.
• Fill the vacutainer or syringe: Once the needle is in place, release the tourniquet and allow the blood to flow into the vacutainer or syringe.

• Remove the needle: Once the vacutainer or syringe is filled, remove the needle and apply gentle pressure to the puncture site with a sterile gauze pad or cotton ball.
• Apply a bandage: Place a bandage over the puncture site to protect it and prevent bleeding.

Infant blood draw sites

When obtaining a blood sample from an infant, the most common sites used are the heel or the antecubital fossa (bend of the arm near the elbow).

However, the choice of site may depend on the age of the infant, the amount of blood needed, and any underlying medical conditions the infant may have.

• For heel sticks, the infant’s foot is cleaned and the area is numbed with a topical anesthetic. A small, sharp lancet is then used to make a quick, shallow puncture in the heel, and the blood is collected on a special card or onto a piece of gauze.
• In the antecubital fossa, the infant’s arm is cleaned and the area is numbed with a topical anesthetic. A small needle is then inserted into a vein, and the blood is collected into a vial or other container.

Note: It’s important to note that obtaining a blood sample from an infant can be a difficult and potentially stressful procedure, so it’s important to use caution and follow proper techniques to minimize discomfort and minimize the risk of infection or injury.
