Cooling spray takes aim at the sting of an IV
NCT ID NCT07821476
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers are testing whether a cooling spray called Pain Ease reduces the pain of getting an intravenous (IV) line. The trial compares Pain Ease with a sterile water spray in 100 adults who need an IV. They also check whether the spray increases germs on the skin after it is cleaned. Participants receive one of the sprays before the IV is placed and answer questions about their experience.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a vapocoolant spray containing hydrofluoroolefins
- What this could lead to
- If the spray works, it could offer a simple way to reduce the pain of getting an IV without a needle for numbing.
- What could go wrong
- The spray may not ease pain better than a plain water spray, and it might not keep the skin as clean as needed. The trial is small and only includes adults up to age 75.
