Summary

This trial tests a gel-like hemostatic agent called Hemoblast bellows to reduce bleeding during heart surgery. About 60 adults undergoing open-heart surgery will receive the gel on their breastbone. Researchers will measure bleeding scores and chest tube output to see if it works.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Hemoblast bellows (a topical hemostatic agent)
What this could lead to
If it works, this could provide a simple way to control bleeding during heart surgery, reducing complications and recovery time.
What could go wrong
This is a small, early-phase trial with only 60 participants. The results may not apply to all patients, and the agent may not significantly reduce bleeding.
