Introduction

Phlebotomy is the process of drawing blood from a patient for diagnostic testing, blood transfusions, donations, or research. One common tool used in phlebotomy is the butterfly needle. Also known as a winged infusion set or scalp vein set, the butterfly needle is a small, thin-walled needle with flexible wings on either side.

What is a Butterfly Needle?

A butterfly needle is typically used when a smaller volume of blood is needed, or when the veins are small or fragile, such as in pediatric or Geriatric Patients. The needle's flexible wings allow for precise control during the Venipuncture process, making it an essential tool in the phlebotomist's arsenal.

Proper Technique for Using a Butterfly Needle

Proper technique is crucial when using a butterfly needle in phlebotomy to ensure accurate blood collection and patient safety. Here are the steps to correctly use a butterfly needle:

1. Prepare the Patient

1. Explain the procedure to the patient and obtain Informed Consent.
2. Position the patient comfortably with the arm extended and the palm facing up.
3. Apply a Tourniquet 3-4 inches above the intended puncture site to engorge the veins.

2. Select the Site

1. Pick a suitable vein for Venipuncture, typically the median cubital vein, cephalic vein, or basilic vein.
2. Clean the site with an alcohol swab in a circular motion starting from the center and moving outwards.

3. Prepare the Equipment

1. Remove the butterfly needle from its packaging without contaminating the sterile needle.
2. Attach the blood collection tube to the needle holder or a vacuum tube system if using one.

4. Perform the Venipuncture

1. Hold the butterfly needle between the thumb and index finger with the wings facing up.
2. Anchor the vein by pulling the skin taut below the intended puncture site.
3. Insert the needle at a 15-30 degree angle with the bevel facing up.
4. Once blood enters the tubing, release the Tourniquet and fill the required tubes in the correct order of draw.

5. Secure and Dispose

1. Apply pressure on the puncture site with a gauze pad and instruct the patient to hold it in place.
2. Secure the needle with a bandage or transparent dressing.
3. Dispose of the used needle in a sharps container according to facility guidelines.

Tips for Using a Butterfly Needle

Here are some additional tips for using a butterfly needle in phlebotomy:

1. Practice Proper Hand Hygiene

Always wash your hands before and after the procedure or use hand sanitizer to prevent the spread of infection.

2. Use the Correct Needle Size

Choose the appropriate Needle Gauge and length based on the patient's age, vein quality, and the intended purpose of blood collection.

3. Position the Patient Correctly

Ensure the patient is in a comfortable position with the arm extended and well-supported to minimize movement during the Venipuncture.

Conclusion

Using a butterfly needle correctly in phlebotomy is essential for accurate blood collection, patient comfort, and safety. Healthcare professionals must follow proper technique, adhere to infection control practices, and prioritize patient care when performing Venipuncture with a butterfly needle. By mastering the use of this versatile tool, phlebotomists can provide quality service and contribute to optimal patient outcomes.
