Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 2–17 who have secondary post-tonsillectomy hemorrhage within 24 hours of arrival and have no bleeding/clotting disorders, no known TXA allergy, and can communicate in English or Spanish.

Probably not a fit

Patients with known bleeding disorders, prior enrollment in this study, or intolerance to tranexamic acid may not benefit.

What this trial studies

This early-phase trial enrolls children aged 2 to 17 years who develop secondary post-tonsillectomy hemorrhage. It administers three consecutive nebulized doses of tranexamic acid, adjusted by weight (500 mg per dose for ≥25 kg, 250 mg per dose for <25 kg), delivered over about one hour. The intervention is given in a hospital or clinic setting by trained clinicians using a nebulizer. Primary aim is to see if neb TXA can control bleeding rapidly without surgical intervention. The trial is sponsored by UT Health San Antonio with NHLBI collaboration and includes multiple sites in California, Rhode Island, and Texas.

Why it matters

Potential benefit: If successful, participants may stop the bleeding without needing another surgery or blood transfusion, leading to quicker recovery.

How similar studies have gone: Previous studies in similar settings suggest tranexamic acid can help control bleeding, but this specific nebulized, pediatric, post-tonsillectomy context is investigational.
