What Butterfly Needles Are Used For？

Blood Draw

Phlebotomists (people who draw blood) regularly use butterfly needles to obtain blood samples for blood-based tests.

Hydration

Butterfly needles can also be used to deliver intravenous fluids if you are dehydrated and either cannot drink fluids or cannot drink enough to compensate for fluid loss.

In some older people, or people receiving end-of-life care who need hydration, butterfly needles can be used subcutaneously (beneath the skin).

Medication

Butterfly needles are useful for delivering medications (such as pain medications) straight into a vein or infusing IV therapies (such as chemotherapy or antibiotics) intravenously.

How Butterfly Needles Are Used？

During venipuncture (the insertion of a needle into a vein), a phlebotomist or nurse will hold the butterfly needle by its wings between the thumb and index finger.    Because the hypodermic needle is short and the grasp is close to the needle, the butterfly needle can be placed more accurately than a straight needle, which can often roll or wiggle.

The short, thin needle is inserted toward a vein at a shallow angle.    Once inserted, the venous pressure will force a small amount of blood into the transparent tubing, providing confirmation that the needle is correctly placed.

The wings can also serve to stabilize the needle once it is in place, preventing it from rolling or shifting.

Once used (for drawing blood or delivering medication), the entire unit is thrown away in a sharps disposal container.    The puncture wound is then bandaged.

Advantages

Because of their small size (far smaller than an intravenous catheter) and shallow-angle design, butterfly needles can access superficial veins near the surface of the skin while causing less pain.

Its use also allows access to small or narrow veins, such as those in infants or older people.    On the other hand, they may be more likely to cause needlestick injuries in healthcare providers than other types of needles.  Newer models have a slide-and-lock sheath that automatically slides over the needle as it is extracted from a vein.

Butterfly needles are ideal for people with small or spastic (rolling) veins, and can even be inserted into the tiny veins of the hand, foot, heel, or scalp.

They are also ideal for people who are hesitant about needles because they are less threatening, and they are less likely to cause profuse vein injury or nerve injury, especially when using a smaller butterfly needle.

If you have been told that you have small veins and have had challenging blood draws in the past, consider requesting the use of a butterfly needle.
