According to these facilities, butterflies may also be occasionally used for intravenous (IV) medications. A common IV medication that is administered through butterfly needles is insulin. This needle is smaller and thinner than a traditional IC catheter and is better, due to its smaller gauge sizes, ranging from 18-27 on average.
Other healthcare providers, however, may only use butterfly needles. These phlebotomists understand the benefits they bring to people who may need them and how they may apply to the greater population. Such phlebotomists may attest to the needle’s merits and how it tends to reduce the risks for profuse bleeding, nerve injury, or vein collapses when the needle is removed due to its size.
Though there have been various demonstrations that butterfly needles are convenient to phlebotomists when conducting blood work or administering IV medications, some facilities still don’t permit any use of butterfly needles. Such providers often attest that traditional needles match the quality of butterflies and that their phlebotomists are exceptional in their capabilities. This logic may be flawed, however, as it is not the quality of the phlebotomist that fully determines the success of needlework but is impacted by the needle type as well.
