Guage 18 in medicine is the size of a needle either for injections or for IV insertion.
I draw it with 18 and inject with 22 if mixed with Haldol or diluted. I use 21 if undiluted.
I think you might be asking about a intramuscular injection and i work with kids and we typically use a 25 or a 23 gauge needle. There are some medications that we use a bigger gauge due to the medi.cation being too thick to put through a smaller gauge. So i guess the biggest i would use is a 19

The gauge of the needle, what the needle is being used for (IV, tattoo, blood draw, injection, etc.) all have an impact on the sensation experienced when a needle penetrates the skin. With injections in particular, the solution's thickness will definitely contribute to it. The thicker the solution, the more painful.
21 gauge, thin-wall 1-1/2 inch needle
the gauge is the measurement of how big around the stud or needle is
The 21 gauge is a smaller needle.
Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.
Yes, the larger the gauge the smaller the needle size.
It could be used as long as the needle length is approximately 1 1/2 inches long so that it reaches the muscle tissue. The flu vaccine injections are given IM (intramuscularly) except if it is the new intradermal type of vaccine, which has its own delivery system with a very tiny needle injected into the layers of skin. The typically sized needle for IM administration of medication is a 22-25 gauge, 1 1/2 inch IM needle. 23 gauge is slightly larger around than a 25 gauge, so it is possible you could feel it slightly more when inserted. A 23 gauge needle has an outer diameter of 0.02525 inches. A 25 gauge needle has an outer diameter of 0.02025 inches. As long as you are able to correctly measure the proper dosage, it could be used.
Yes, a 30 gauge needle would be tiny, while an 8 guage needle is huge.
