Fingertip test may rival blood test in sepsis care
NCT ID NCT06727318
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 192 adults with septic shock to see if a simple finger-pressure test (capillary refill time) could predict outcomes as well as a standard blood test (lactate level). Researchers measured both at the same time and tracked which patients got worse or died within 28 days. The goal was to find a faster, cheaper way to monitor these critically ill patients.
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 help doctors use a simple bedside test (capillary refill) to quickly assess septic shock patients, potentially improving care.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks at correlations, so it cannot prove that using capillary refill improves survival.
