New video technique could make a key ICU test more reliable
NCT ID NCT05573659
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether using a video to measure capillary refill time (how fast skin color returns after pressure) is more consistent than the usual visual method. Researchers compared measurements taken by different doctors in 59 ICU patients. The goal was to see if the video method reduces variability between observers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a more reliable way to measure capillary refill time in critically ill patients, potentially improving early detection of shock.
- What could go wrong
- This is a small, single-center study with only 59 participants, so results may not apply to all ICU settings. The study only measures reproducibility, not patient outcomes.
