What this trial studies

This study evaluates the effectiveness of tranexamic acid and adrenaline in preventing bleeding during diagnostic bronchoscopy procedures. Both medications are applied topically to assess their ability to reduce the incidence of bleeding complications, which can impact the quality and outcomes of the procedure. The study aims to determine which of the two agents is more effective in maintaining hemostasis and improving patient safety during bronchoscopy. Participants will be randomly assigned to receive either tranexamic acid, adrenaline, or a placebo.

Who should consider this trial

Good fit: Ideal candidates include patients scheduled for diagnostic bronchoscopy with sampling procedures who can provide informed consent.

Not a fit: Patients with contraindications for bronchoscopy, coagulopathy, or those on certain anticoagulant therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved safety and outcomes for patients undergoing bronchoscopy by reducing the risk of bleeding complications.

How similar studies have performed: Previous studies have shown that both tranexamic acid and adrenaline can be effective in managing bleeding during bronchoscopy, suggesting that this approach has potential based on existing evidence.
