New study aims to speed up bleeding diagnosis in the operating room
NCT ID NCT06637943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways to diagnose bleeding problems during surgery: a quick bedside test (viscoelastic test) and standard lab tests. The goal is to see which method gives faster results, helping doctors treat bleeding sooner. About 210 adults having high-risk surgeries (like heart, joint replacement, or spine surgery) will take part.
