Treatment of Post-Tonsillectomy Hemorrhage With Nebulized Tranexamic Acid: Initial Investigation of a Novel Therapeutic Modality.

Objectives: The use of nebulized tranexamic acid (TXA) in massive pulmonary hemorrhage is well-described. Published utilization in post-tonsillectomy bleeding (PTB) is limited to a single case. This study examines whether TXA resulted in change of operative intervention necessity and narcotic utilization.

Methods: This was a retrospective cohort study at a single, urban academic medical center in the United States. Chart review was conducted of all patients who presented to the hospital for post-tonsillectomy bleed (PTB) between 3/1/2018 and 7/1/2020. Demographic data, intervention modality, need for control under general anesthesia, and opioid use were collected and analyzed.

Results: Twenty-one patients underwent a total of 23 visits for PTB over the study period. Control of hemorrhage without need for operating room intervention for PTB was 100% (6/6) for patients receiving TXA nebulizer and 53% (9/17) for those receiving other treatment modalities. Opioid usage in hospital and on discharge was also lower in patients receiving TXA nebulizers. All results were statistically significant.

Conclusions: Our study supports nebulized TXA as an effective, non-invasive mode of hemostasis in patients presenting to the emergency department for post-tonsillectomy hemorrhage. Nebulized TXA may prevent the need for general anesthesia and operative intervention. Otolaryngologists should consider addition of this novel treatment appropriation of TXA to their management options for postoperative tonsillar hemorrhage.
