Which blood thinner is safest for ICU patients with kidney failure? large study aims to find out
NCT ID NCT07365644
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at ICU patients with kidney failure who need blood thinners to prevent dangerous clots. Doctors currently use different types of heparin, but it's unclear which is safest and works best when kidneys are weak. The study will track over 1,100 patients to compare bleeding risks and clot prevention across the various heparin options.
