TXA for Everyone: Inhaled TXA for Hemoptysis

03 Dec
December 3, 2018

Background: Use of tranexamic acid (TXA), an antifibronlytic medication,  has certainly become popular for numerous indications (i.e. trauma, uterine bleeding, epistaxis).  Patients with hemoptysis, frequently come through EDs, and as an ED healthcare provider, I am unable to provide the definitive therapies of bronchial artery embolization and bronchoscopy for these patients at many of the institutions in which I work.  And, of course, it’s not like I can just put my finger on the bleeder. There is no real effective medical therapy for hemoptysis, other than antibiotics for infection.  I often find myself helpless with these patients as all I can do is transfer them to larger institutions where definitive therapies can be done.  Well hold on…It turns out inhaled TXA may be an option to reduce bleeding in patients with hemoptysis.  Thus far the evidence for this has  only been from small case series.  There have been no prospective studies evaluating nebulized TXAs effectiveness as an inhaled treatment for hemoptysis.  I have certainly used this treatment for post-tonsillectomy bleeding and have at times used it for hemoptysis, with great success, but it would be nice to see some evidence to support this practice.

TICH-2: TXA for Spontaneous ICH?

July 30, 2018

Background: Spontaneous, non-traumatic intracerebral hemorrhage, is one of the only stroke subtypes without a proven treatment. It is not as common as ischemic stroke, representing up to 20% of all strokes, but it accounts for almost half of all stroke deaths worldwide.  Furthermore, about a quarter of intracerebral hemorrhage can be complicated by hematoma expansion which can occur up to 24 hours later and is itself associated with poor outcomes.  There have been only small trials looking at the use of tranexamic acid in this group of patients, until now.  The Tranexamic acid for hyperacute primary IntraCerebral Haemorrhage (TICH-2) trial looked to see if intravenous TXA reduces death and dependence when given within 8 hours of spontaneous ICH.

Topical TXA in Epistaxis

December 7, 2017

Background: Epistaxis is a common Emergency Department (ED) complaint with over 450,000 visits per year and a lifetime incidence of 60% (Gifford 2008, Pallin 2005). Standard anterior epistaxis treatment consists of holding pressure, use of local vasoconstrictors, topical application of silver nitrate and placement of an anterior nasal pack. ED patients with epistaxis often fail conservative management and end up with anterior nasal packs which are uncomfortable. This is even more common in the group of patients who are taking antiplatelet agents like aspirin or clopidogrel. Recently, the use of topical tranexamic acid (TXA) has been described in patients with anterior epistaxis with shorter time to epistaxis control and shorter ED length of stay (Zahed 2013). However, prior studies have not focused specifically on patients taking antiplatelet agents. Read more →

It’s Time for Tranexamic Acid (TXA) in Massive Hemorrhage

20 Nov
November 20, 2017

Background: Bleeding from massive hemorrhage in trauma and post-partum are a major cause of death worldwide. There have been two large randomized controlled trials, in trauma and post-partum hemorrhage that have shown administration of TXA within 3 hrs of bleeding onset reduces death due to bleeding. The current meta-analysis that we are going to best panerai replica review sought to quantify the effect of treatment delay in acute severe bleeding by analyzing individual patient-level data from the two randomized clinical trials mentioned above.

The WOMAN Trial: Early TXA in Post-Partum Hemorrhage

22 May
May 22, 2017

Background: Post-partum hemorrhage (PPH) is the leading cause of maternal death worldwide. It is typically defined as > 500 ml of blood loss within 24 hours of giving birth. However, PPH encompasses a broad spectrum of disease from mild oozing over hours to rapid exsanguination and death. The burden of mortality from PPH is shouldered mainly by developing countries thus requiring cost-effective treatment modalities. Tranexamic acid (TXA) is one such possibly modality. TXA works by inhibiting the breakdown of fibrinogen and fibrin by plasmin. In essence, it stabilizes clot that the body naturally forms. TXA has a well established role in reducing death in trauma patients as demonstrated in the CRASH-2 trial (CRASH-2 2010) and is already used by many performing resuscitations in resource strapped locations due to its availability and low cost. Whether early TXA in post-partum hemorrhage reduces mortality while avoiding significant clotting complications (DVT, PE, ACS, CVA) is unknown. Read more →
