Summary

This trial tests whether a cold spray (cryotherapy) can numb the skin and reduce pain when drawing blood from an artery in intensive care patients. About 200 adults in the ICU who need an arterial blood gas test will receive the spray before the puncture. The study measures pain levels and how easy the procedure is for healthcare workers.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cryotherapy (vapocoolant spray)
What this could lead to
If effective, this cold spray could offer a simple, drug-free way to reduce pain during a common ICU procedure.
What could go wrong
This is a small, early-stage trial. The cold spray may not significantly reduce pain, and results may not apply to all patients.
