NCT04961528
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.
NCT07528170
At St. Olavs Hospital, a prospective collection of data on complications related to CT-guided lung biopsies has been conducted over several years as part of quality control study. The primary aim of this quality control study is to map complications in all patients who have undergone percutaneous CT-guided lung biopsy at St. Olavs Hospital from May 2012 to December 2023.
NCT06145191
Endobronchial bleeding is a common complication of bronchoscopy. Major bleeding, although rare, can be life threatening and often requires advanced therapeutic interventional pulmonary procedures which are not widely available. Minor bleeding can negatively impact outcomes such as diagnostic yield, sample size and bronchoscopy duration. Both adrenaline and tranexamic acid are successfully used topically for hemostasis during diagnostic bronchoscopy. The aim of this study is to evaluate the efficacy of prophylactically applied adrenaline and tranexamic acid in bleeding prevention during diagnostic bronchoscopy.
NCT03126968
Bleeding poses potential for significant complication after transbronchial lung biopsies. The investigators hypothesize that prophylactic intrabronchial instillation of topical epinephrine will reduce the likelihood of bleeding. The investigators plan a double-blind, placebo controlled trial to evaluate this hypothesis.
NCT05634200
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
NCT03625947
The aim of this study is to evaluate the efficacy, the safety and the main predictors of success of bronchoscopic Argon Plasma Coagulation in patients with hemoptysis caused by endobronchial malignancies.
NCT05648656
Hemoptysis is a common presentation in medical emergency. Prompt medical therapy, bronchoscopic and endovascular procedures remains the cornerstone of management for both diagnostic as well as therapeutic purpose in hemoptysis. Priority is given for medical management to achieve hemostasis and prevent aspiration as well as treatment of underlying etiology, before undertaking any definitive bronchoscopic or endovascular intervention. While majority of the patients are managed successfully by prompt medical therapy, only the refractory cases and life-threatening hemoptysis need more definitive procedures like DSA guided bronchial artery embolization and bronchoscopic procedures like endobronchial biocompatible glue, endobronchial embolization using silicone spigots, endobronchial stents, laser photocoagulation. Tranexamic acid is an anti-fibrinolytic agent which prevent breakdown of fibrin clots, thus helping in clot stabilization and controlling bleeding. As a medical therapy Tranexamic Acid is used for bleeding control in hemoptysis as well as other surgical or traumatic bleeding. Previously conducted institutional study comparing IV infusion of TXA to placebo in patients with sub massive hemoptysis showed results favoring TXA over placebo in terms of decreasing frequency \& quantity of hemoptysis, duration of hospital stay and need for DSA/ broncoscopic/ surgical intervention and blood transfusion (1). While the oral and IV routes have been most commonly studied, use of novel approaches like aerosolized TXA and endobronchial instillation of TXA during bronchoscopy have showed positive results in achieving hemostasis in hemoptysis (2). A recently conducted RCT, to assess the effectiveness of TXA nebulization in sub-massive hemoptysis concluded that nebulized TXA is effective in reducing the frequency and quantity of hemoptysis. Nebulized TXA was also found to be safe as no severe ADR was noted during its use as per previous RCT as well as multiple case reports. However, because of limited number of research with small sample size and barring some case reports evidence for the use of nebulized TXA is limited in hemoptysis. In hemoptysis nebulized form of TXA is supposed to reach local site of bleeding (lung/ airway) promptly at a higher concentration leading to rapid control of hemoptysis. So, this study has been planned to evaluate further this novel approach of TXA nebulization for the management of hemoptysis. Similarly, data regarding adverse drug reaction related to TXA nebulization is also limited. This study will produce additional information regarding efficacy, safety and ADR related to TXA nebulization.

Massive hemoptysis is a serious disease of respiratory system, which seriously endangers the life of patients. There are obvious difficulties in the treatment of hemoptysis. In the traditional treatment, patients still have the risk of massive hemoptysis and suffocation, and the risk control in the treatment process cannot be ensured. Intra - airway interventional therapy, especially the hemostatic technique of intra - airway balloon catheter, is an important means to control the risk of hemoptysis. However, the current intraairway balloon catheter therapy technology is immature, complicated and difficult to operate, and the cost is high. There is a lack of special balloon for hemostasis, and the balloon borrowed for other purposes cannot meet the needs of hemoptysis treatment. Therefore, it is urgent to develop a new balloon catheter for airway hemostasis, which has simple technical operation, easy to master and popularize, efficient and safe function and structure. According to this requirement, this project designed and developed hemostatic balloon catheter with multiple functions such as self-guiding, anti-displacement, anti-leakage and detachable rear end, so as to make the treatment of massive hemoptysis more safe and effective, simpler and faster, so as to be widely applied in clinical practice.
NCT04771923
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.
NCT04825158
Anaphylaxis is a severe and life-threatening complication during the perioperative period. Perioperative anaphylaxis is still associated with a significant mortality despite quick and efficient management using epinephrine, the mainstay of acute treatment. Experimental data and few case reports are suggesting that hemostasis, and more precisely platelets, could play a role in anaphylaxis. Our main hypothesis is that activation of the hemostatic system contributes to the severity of the reaction
NCT04087135
Our study first aims to develope a realistic cadaver model of hemoptysis based on Thiel's embalmed cadavers. Secondly, participants will intubate the hemoptysis cadaver model with (a) the direct laryngoscopy with MacIntosh blade, (b) the videolaryngoscopy with McGrath XBlade and (c) the videolaryngoscopy with McGrath XBlade and a suction advance before the optic of the camera. We hypothesis that, in simulated hemoptysis on the Thiel's embalmed cadaver, the rate of failed intubation at first try will be different depending on the laryngoscope used.
NCT01278199
Severe hemoptysis is a life-threatening condition, with an unpredictable course. The efficacy of bronchial artery embolization (BAE) is well established for the treatment of severe hemoptysis, with short and long-term bleeding controls obtained in 70 to 100% and 50 to 90% of cases, respectively. As complications related to vascular interventional radiology may occur in 5 to 10% of cases, the benefit-risk balance might be less clear in acute hemoptysis of mild-to-moderate abundance (volume between 100 and 200 ml) and no criteria of severity (respiratory failure or hemodynamic instability). There is no available data comparing the safety and efficacy of BAE combined with medical measures to those of medical measures alone in the treatment of non-severe acute hemoptysis of mild-to-moderate abundance.
