The best gauge for fragile veins would depend on many factors. The patient often already knows what gauge you should use. Most often that is a butterfly because they are the smallest available.
The medical professionals collecting the blood have a wide selection of needles of different gauges (or "bores") to cover all circumstances. They can start an IV on a newborn with the right gauge needle.
A 23-gauge needle is typically used for venipuncture when accessing smaller veins, such as those found in pediatric patients or patients with fragile veins. It is also preferred for drawing blood when minimizing trauma is a priority, as it causes less damage to the vessel compared to larger gauge needles. Additionally, a 23-gauge needle may be suitable for specific laboratory tests that require a smaller volume of blood.
Yes, use the thinnest (highest #) gauge needle possible, 30+ gauge with a 3/8" tip most likely. Technique is everything, make sure to register on the first hit. The veins in your hands are fragile & if you mess them up it'll be obvious what's going on...

Love is fragile. And we're not always its best caretakers. We just muddle through and do the best we can. And hope this fragile thing survives against all odds.

Every phlebotomist hopes to see large, prominent veins that are easily visible just below the surface of the skin. Veins with an elastic (sometimes described as a 'bouncy') quality usually indicate large, healthy veins that are less likely to collapse. The medial cubital or cephalic veins are the most common veins used in venipuncture. Veins which are fibrosed, fragile or inflamed should be avoided.
It is determined by the size of the veins
As people age, the walls of veins may become less elastic and more rigid due to changes in the structural proteins within the vein walls. This can cause the veins to narrow or become smaller in diameter. Additionally, the accumulation of fatty deposits or plaques within the veins can contribute to their narrowing.

Commonly used needle gauges for blood draws are 21-gauge and 22-gauge needles. The 21-gauge needle is often preferred for adults due to its balance between flow rate and comfort, while the 22-gauge is frequently used for pediatric patients or those with smaller veins. In some cases, a 23-gauge needle may be used for very small veins. The choice of gauge depends on the patient's age, vein size, and the volume of blood needed for testing.
