Could a simple shot replace IV blood thinners for ECMO patients?
NCT ID NCT04496362
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if giving the blood thinner heparin as a shot under the skin is as safe and effective as the standard method of giving it through an IV for adults on ECMO (a machine that helps the lungs). The goal is to see if the shot method causes fewer bleeding or clotting problems. About 100 participants will be randomly assigned to one of the two approaches.
