What is the difference between 22G and 25G needles?

Summary of evidence. In our study, the sensitivity of the 25G needle was 93%, while that for the 22G needle was 91%, and there was no statistically significant difference between the needles.

What size IV needles do nurses use?

IV needles are sized by gauges, and the smaller the gauge number, the bigger the needle will be.
