Brief summary
Endobronchial bleeding is a relatively common complication of diagnostic bronchoscopy. Both tranexamic acid and adrenaline are used topically for the control of endobronchial bleeding. The aim of this study is to compare the efficacy of tranexamic acid with adrenaline in controlling iatrogenic endobronchial bleeding after diagnostic bronchoscopy.
Interventions
Topical instillation of tranexamic acid up to 3x. If bleeding is not controlled patients crossover to adrenaline.
Topical instillation of adrenaline up to 3x. If bleeding is not controlled patients crossover to tranexamic acid.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage (%) of successfully controlled iatrogenic endobronchial bleeding in each arm | Until the end of the individual procedure (bronchoscopy), up to 1 minute after each drug application. | Bleeding control is assessed by the bronchoscopist by visual confirmation of clot formation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number (N) of tranexamic acid/adrenaline applications necessary to control endobronchial bleeding | Until the end of the individual procedure (bronchoscopy), up to 1 minute after each drug application.. | Bleeding control is assessed by the bronchoscopist by visual confirmation of clot formation. |
| Number (N) of recurrent bleeding episodes after instillation of tranexamic acid/adrenaline | During the first 24 hours immediately after the individual procedure (bronchoscopy). | Recurrent bleeding episodes and hemoptysis requiring medical and/or bronchoscopic intervention. |
| Percentage (%) of successfully controlled iatrogenic endobronchial bleeding in each arm in relation to the severity of bleeding. | Until the end of the individual procedure (bronchoscopy), up to 1 minute after each drug application.. | As assessed by the bronchoscopist by visual analogue scale (VAS) 1-10 (1 very mild - 10 very severe). |
| Percentage (%) of successfully controlled iatrogenic endobronchial bleeding in each arm | Until the end of the individual procedure (bronchoscopy), up to 1 minute after each drug application. | In different indications and methods (transbronchial lung biopsy, endobronchial biopsy, transbronchial needle aspiration, bronchial brushing). |
| To compare number (N) of adverse events in each arm | During and up to 1 month after the procedure (bronchoscopy). | — |
