Nebulized tranexamic acid to stop post-tonsillectomy bleeding in children
Official title: TranExamic Atomized for Pediatric Post-Operative Tonsillectomy Hemorrhage (TEAPOT): A Pilot and Feasibility Study
Run by The University of Texas Health Science Center at San Antonio · NCT06580509 · Data updated 2026-11-12
We will try a medicated mist (nebulized tranexamic acid) to stop bleeding after tonsillectomy in children aged 2 to 17.

Is this trial a fit for you?
✓Likely a good fit
Children aged 2 to 17 who present to the ED with secondary post-tonsillectomy hemorrhage (more than 24 hours after the original operation) and who do not have contraindications to TXA are ideal candidates.
✕Probably not a fit
Patients with known bleeding or clotting disorders, pregnancy, a known allergy to tranexamic acid, those already intubated, or those who require immediate operative control of bleeding are unlikely to benefit from this nebulized approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This pilot gives three consecutive doses of nebulized tranexamic acid (TXA) to children who present with secondary post-tonsillectomy bleeding. Doses are weight-based: 500 mg per dose for children over 25 kg and 250 mg per dose for children under 25 kg, delivered via a standard nebulizer over roughly one hour. Treatments are administered in a clinical setting (emergency department or hospital) by trained staff, and patients are monitored for bleeding control and safety. The trial will record whether the mist stops bleeding without needing return to the operating room or blood transfusion.
Why it matters
Potential benefit: If successful, this approach could stop bleeding without another surgery or transfusion, avoiding additional anesthesia and hospital procedures for children.
How similar studies have gone: Topical and nebulized uses of tranexamic acid have shown promising results in small studies and case reports for upper airway bleeding, but robust pediatric trials for post-tonsillectomy nebulized TXA are limited.
