What Are 18G Butterfly Needles?
Butterfly needles, also known as winged infusion sets, are short, thin needles attached to flexible tubing and plastic wings for better handling. The 18G refers to the needle’s gauge—the thickness of the needle. An 18G butterfly needle is a mid-range gauge, balancing blood flow speed and patient comfort.
Key Features of 18G Butterfly Needles:
- Short length (typically ¾ to 1 inch) – Ideal for superficial veins.
- Flexible tubing – Reduces needle movement, minimizing vein damage.
- Safety mechanisms – Many models come with retractable or shielded needles to prevent needlestick injuries.
- Precision control – The wings allow for better maneuverability during insertion.

Why Choose 18G Butterfly Needles for Blood Draws?
Optimal Balance Between Flow Rate and Comfort
An 18G needle is neither too thick (which can cause discomfort) nor too thin (which may slow blood collection). It provides a fast flow rate while being gentle on veins, making it ideal for patients with normal to slightly fragile veins.
Reduced Risk of Hemolysis
Smaller gauge needles (like 23G or 25G) may cause hemolysis (rupturing of red blood cells) due to excessive suction pressure. The 18G butterfly needle minimizes this risk while ensuring efficient blood collection.
Ideal for Difficult Venipuncture
Patients with small, rolling, or fragile veins benefit from butterfly needles due to their precise insertion and reduced movement during the procedure. Learn more about how butterfly needles help in difficult blood draws.
Enhanced Safety Features
Many 18G butterfly needles come with safety-engineered designs, such as retractable needles or shields, reducing the risk of accidental needlesticks.
How to Use 18G Butterfly Needles Safely
Step-by-Step Guide:
- Prepare the Patient – Explain the procedure and ensure they are comfortable.
- Select the Vein – Palpate and choose a suitable vein (typically in the forearm or hand).
- Insert the Needle – Hold the wings, insert at a 15-30 degree angle, and advance smoothly.
- Secure the Needle – Tape the wings down to prevent dislodgement.
- Collect Blood – Attach the vacutainer or syringe and draw blood.
- Remove Safely – Withdraw smoothly, apply pressure, and dispose of the needle in a sharps container.
