In which situation would you most likely use a winged infusion set (butterfly)?

A winged infusion set, commonly referred to as a butterfly, is specifically designed for situations where veins are small, difficult to access, or when working with patients who may be more sensitive, such as children or the elderly. The flexibility and stability of the butterfly wings provide better maneuverability and grip when inserting the needle, which is especially important in smaller or superficial veins found in the hands. This makes it ideal for pediatric and geriatric patients, who often have fragile veins compared to adults with larger veins.

The design of the butterfly set allows for a more precise insertion and minimized movement during blood draws, which is crucial for maintaining patient comfort and obtaining an adequate sample. In contrast, other scenarios such as drawing from large veins or conducting rapid blood collection procedures typically utilize straight needles or larger gauge needles that are more efficient for such tasks. Additionally, the use of a butterfly set is not limited to emergency situations but is preferred in routine venipuncture for certain populations, highlighting its specialized application rather than a general or emergency use.
