Which technique is recommended when performing a venipuncture on a difficult vein?

Using a butterfly needle for venipuncture on difficult veins is highly recommended because this type of needle is designed with wings that provide better control and stability during the insertion process. The small gauge of butterfly needles also makes them suitable for accessing smaller, more fragile veins that may be challenging to puncture with a standard needle. Additionally, the angled design allows for better visibility of the vein, which can be crucial when dealing with veins that are not easily identifiable or are deeper beneath the skin.

In situations where veins are difficult to access, having more control and visibility greatly increases the likelihood of a successful draw, thereby minimizing patient discomfort and the chance of complications like hematomas or missed sticks.
