Understanding Butterfly Needles
Butterfly needles, otherwise known as scalp vein sets, are a form of blood collection device that can provide more comfort to patients with small or difficult veins. They have been specially designed for accessing the superficial vessels and thus serve both extraction purposes (e.g., drawing blood) and injections via an intravenous route.
The butterfly needle’s safety is heightened by its design, reducing the risk of accidental needle sticks, and making it a preferred choice among healthcare staff. This article provides comprehensive details about butterfly needles, benefiting readers, especially patients with hard-to-reach veins relying on their safe usage during phlebotomy procedures if other options prove ineffective.
Components of a Butterfly Needle
The butterfly needle comprises various components, including a thin hypodermic needle, wings for stability during insertion and control in winged infusion procedures, and flexible tubing for enhanced comfort during blood collection or IV infusions, reducing pressure on veins. Transparent tubes connect all these elements together.
Butterfly needles are available in sizes ranging from 18-27 gauges, with shorter ones (21/23 gauges) ideal for blood draws due to lower associated pain. Their usage varies based on length; shorter needles require shallower angles, making them particularly useful for accessing superficial veins in individuals with challenging vessel locations.
The unique features of butterfly needles, including superior maneuverability, contribute to their excellence, especially in terms of accuracy, among other advantages.
Choosing the Right Size
Using the correct size of butterfly needles is crucial for accurate results and minimal patient discomfort during blood draws or IV infusions. Commonly, 21 and 23 gauge needles are used for adults, while smaller gauges (21-25) are suitable for pediatric patients to ensure proper blood flow. Thorough selection of butterfly needle size is essential, taking into account both accuracy and comfort factors.
Preparing for Blood Draw or IV Infusion
Before starting a blood draw or IV infusion with the butterfly needle, certain equipment must be collected and appropriate measures must be taken to prepare the patient. This involves selecting an adequate-sized needle, obtaining any required supplies for drawing blood or infusing fluids, and making sure that the person being treated is as comfortable and relaxed as possible.
Preparation steps before using butterfly needles not only reduce the chances of complications but also enhance the overall experience for everyone involved in care. Essential aspects, such as selecting the right needle size and assembling necessary tubes/IVs, are meticulously considered during the preparation process. This involves choosing materials, ensuring patient relaxation, and covering all aspects from start to finish, contributing to a smoother procedure for blood sample extraction using butterfly needles.
When doing a blood draw or infusion with the butterfly needle, you need equipment such as a syringe and ETS holder for drawing samples. The collection tubes must be valid when taking specimens of red blood cells from patients.
For an IV infusion, it’s important to have tubing as well as fluids in preparation for this procedure using the same type of needle mentioned earlier (a butterfly one) to successfully collect the needed amount of blood.
For a successful infusion or blood draw using the butterfly needle, it is important to have proper patient preparation. It is recommended that they sit in an easy and relaxed posture while determining where exactly on their arm has veins capable of supporting this type of procedure.
To carry out the process correctly, one must cleanse and sterilize with either rubbing alcohol or another sanitizing substance at the site before inserting the needle into place. Make sure you use techniques such as palpation or dependent positioning if locating harder-to-fill veins proves tricky!

Letting the antiseptic dry completely before continuing on will guarantee full sterilization and reduce contamination risk as much as possible. This meticulous approach is crucial for safety when handling a butterfly needle device to prevent post-insertion infections.
Inserting the Butterfly Needle
Hold the butterfly wings between your thumb and index finger, and use your other hand to pull the patient’s skin around the vein. Slowly insert the needle into this area at a shallow angle of 10-15 degrees until you see blood in the tubing. Attach collection tube if drawing sample or IV bag for fluids then adjust the flow rate as required. Be sure to continuously monitor the patient/needle site during the procedure for any possible problems that may arise.
Collecting Blood Samples or Administering IV Fluids
The butterfly needle is inserted for blood sample collection or IV fluid administration. Attach the required tubes for specimen collection, drawing according to specified requirements. For intravenous infusions, connect tubing from the needle’s connector, set the correct rate per healthcare provider instructions, and monitor for any potential discomfort throughout the treatment process.
Removing the Butterfly Needle and Aftercare
It is essential for both the patient’s health and the safety of healthcare providers that proper aftercare and disposal methods be taken once a butterfly needle or infusion has been utilized. This includes applying pressure at the insertion site to cease any bleeding, disposing of used needles into an appropriate sharps container, and monitoring the individual for signs of complications.
Prompt removal of these needles followed by attentive care can help ensure safe practices in clinics today.
Safely Removing the Needle
To prevent accidents involving the butterfly needle, carefully follow these steps:
Release the tourniquet and gently withdraw the device from the vein. Apply pressure with a clean gauze or cotton ball immediately to stop bleeding. Engage the safety feature, if available, to prevent unintentional pokes or contact with used needles during disposal in sharps containers.
Aftercare and Disposal
Following butterfly needle removal, it’s crucial to provide proper aftercare. This includes cleaning and drying the insertion area with a chlorhexidine/alcohol swab, applying gentle pressure using sterile gauze or a cotton ball for hemostasis, and, if needed, using an adhesive bandage or tape. Patients should closely monitor the site for signs of infection and contact their healthcare provider if uncertain. Disposal of used needles must adhere to local regulations using special sharps containers to ensure safe handling of materials.
Troubleshooting Common Issues
When using butterfly needles, common challenges like vein collapse or difficulty accessing veins can lead to slow blood flow and blockages. To troubleshoot, ensure the right needle size for your situation, avoiding too big for potential tissue damage or too small for difficulty drawing blood. Proper preparation before insertion and minimizing movements during the process are essential to prevent complications and ensure successful sample collection.
Vein Collapse or Difficulty Accessing Veins
When inserting a needle into the vein, ensure that it is placed at an appropriate angle and depth to prevent the potential collapse of vessels. Too much pressure can cause blood leakage causing bruising, pain, and swelling. For more difficult access points, consider palpating or elevating the body part as well as using devices for improved visualization of superficial veins. Drinking water may also help dilate them for easier access.
