Bigger IV, same pain? new study challenges old belief
NCT ID NCT07629427
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two sizes of IV cannulas (18-gauge vs 20-gauge) in emergency patients to see if the larger one causes more pain or is harder to insert. About 204 adults with low-to-moderate difficulty for IV access will be randomly assigned to one size. Patients will wear goggles so they don't know which size they get. The goal is to find out if the larger cannula, which can deliver fluids faster, is as comfortable as the smaller one.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
peripheral intravenous cannula (18-gauge or 20-gauge)
What this could lead to
If larger cannulas cause no more pain, emergency staff may use them more often, improving care for patients who need fast fluids or contrast.
What could go wrong
This is a small, single-center study. Results may not apply to all patients or settings. Pain is subjective and hard to measure precisely.
