- Masking Details
- The investigational pharmacist will be responsible for randomizing on the day of bronchoscopy to placebo or Tranexamic acid in a 1:1 fashion using REDCap software. The pharmacist will be the only individual aware of the randomization assignment. All other study personnel will be blinded to the randomization assignment.
