The Efficacy of Tranexamic Acid and Adrenaline to Control Endobronchial Bleeding

During bronchoscopy (a procedure using a thin, flexible camera to look inside the airways), doctors sometimes take small tissue samples (biopsies) to diagnose lung conditions. This can cause bleeding in the airway. Doctors currently use a medicine called adrenaline to stop this bleeding, but it doesn't always work, and bleeding can come back afterward. Another medicine, tranexamic acid, may work better because it helps blood clot and stay clotted, rather than just narrowing the blood vessels. This study compared tranexamic acid and adrenaline, both given directly onto the bleeding site through the bronchoscope, in patients who developed moderate bleeding after a biopsy. The goal was to find out which medicine stopped the bleeding better right away, and which one was less likely to let the bleeding start again within 30 minutes.

HISTOACRYL® Used for Embolization of Thoracoabdominal Artery Bleeding

This observational study will collect information from adult patients in Japan who are treated with Histoacryl® to stop bleeding from arteries in the chest or abdomen, in order to better understand how well the treatment works and how safe it is during routine medical care.

Nebulized Versus Intravenous Tranexamic Acid for Hemoptysis

This clinical trial aims to compare two different ways of giving a medication called tranexamic acid to patients who are coughing up blood (a condition known as hemoptysis). Coughing up blood can be a serious medical issue that needs to be stopped quickly. Tranexamic acid is a well-known medication that helps blood to clot and stops bleeding. Usually, this medication is given through an intravenous (IV) line directly into a vein. However, doctors are now studying if giving the medication through a breathing mask (nebulizer) might work just as well or better. A nebulizer changes the liquid medicine into a fine mist so the patient can breathe it directly into their lungs, targeting the exact area where the bleeding is happening. To find out which method is better, researchers will randomly assign 170 adult patients who come to the hospital coughing up blood into two equal groups: Group 1: Will receive the tranexamic acid medication inhaled through a nebulizer mask. Group 2: Will receive the tranexamic acid medication through a standard IV line. The main goal of the study is to see which treatment is more successful at completely stopping the bleeding within 24 hours. Researchers will also closely monitor the patients to see how quickly the bleeding stops, how long patients need to stay in the hospital, and if there are any side effects from either treatment method.

ACid Tranexamic or Terlipressin for Initial Emergency Treatment of Mild to seVere hEmoptysis: a Randomized Trial.

The study aims is to verify the hypothetize that inhaled Tranexamic Acid (TXA) or Terlipressin (TER) will be associated with an increase in the rapid control of hemoptysis without side-effects. This randomized double-blind multicenter triple arm trial compares the administration of TXA to TER to placebo in patients with mild to severe hemoptysis.

Utility of Bronchoscopy in Patients With Haemoptysis and Negative Chest CT Scan (ULYSSES)

Conflicting evidence exist in the literature on the utility of bronchoscopy in patients with haemoptysis and negative/non-diagnostic chest CT scan. The primary aim of this prospective, observational, multicenter study is to evaluate the utility of bronchoscopy in patients with haemoptysis and negative/non-diagnostic CT scans. Secondary aims are related to the utility of bronchoscopy to detect occult malignancies, the source of the bleeding and the clinical features of the cohort
