Preparation

Before inserting a butterfly needle, it is essential to gather all the necessary supplies and ensure that the patient is properly prepared for the procedure. This includes:

  1. Gathering the butterfly needle, collection tubes, alcohol swabs, gauze, and adhesive bandages
  2. Confirming the patient's identity and verifying the blood draw order
  3. Explaining the procedure to the patient and addressing any concerns or questions they may have
  4. Ensuring the patient is in a comfortable position with their arm extended and supported

Techniques for Inserting a Butterfly Needle

Inserting a butterfly needle requires precision and skill to minimize patient discomfort and prevent complications. Below are the proper techniques for inserting a butterfly needle:

Cleaning the Site

  1. Put on gloves before starting the procedure
  2. Select a suitable vein for blood draw, typically in the antecubital area of the arm
  3. Clean the site with an alcohol swab in a concentric motion starting from the center and moving outward
  4. Allow the site to dry completely before proceeding with the blood draw

Positioning the Needle

  1. Remove the cap from the butterfly needle and hold it between your thumb and forefinger
  2. Position the needle at a 15 to 30-degree angle to the skin with the bevel facing up
  3. Gently insert the needle into the vein with a smooth, controlled motion
  4. Observe for flashback of blood in the tubing to confirm proper placement in the vein

Securing the Needle

  1. Once blood is observed in the tubing, stabilize the needle with one hand while releasing the Tourniquet with the other hand
  2. Attach the collection tube to the hub of the needle and allow the blood to flow into the tube
  3. Use a gentle back-and-forth motion to ensure adequate blood flow
  4. Remove the collection tube once an adequate amount of blood has been collected

Completing the Procedure

  1. Once the blood draw is complete, remove the needle from the vein in a smooth, controlled motion
  2. Apply pressure to the site with gauze to stop any bleeding and prevent bruising
  3. Dispose of the needle and other contaminated supplies in a sharps container
  4. Cover the site with an adhesive bandage and ensure the patient is comfortable before they leave
