TXA in combat casualty care--does it adversely affect extremity reconstruction and flap thrombosis rates?

Military Medicine

Abstract

Tranexamic acid (TXA) is an antifibrinolytic that competitively inhibits the activation of plasminogen to plasmin. In recent years, the military has adapted TXA's use in combat casualties suffering severe hemorrhagic injuries. The purpose of this study is to examine the association between TXA on complications such as venous thromboembolic events (VTEs) and flap-related thrombosis in combat trauma patients undergoing tissue transfer for extremity reconstruction. A retrospective chart review of war wounded undergoing extremity reconstructions from 2003 to 2012 at Walter Reed National Military Medical Center was completed. Data collected included patient demographics and administration of TXA. Outcomes measured included VTE rates and flap complications in TXA and non-TXA cohorts. From 2003 to 2012, 173 extremity flap procedures were performed (100 pedicle, 73 free flaps). TXA was used in 11% of all patients reviewed. The overall VTE rate was 23.7%; however, there were no documented VTEs in patients who received TXA. Total flap complications, 26% versus 21%, or flap failure, 5% versus 4%, (p=0.571 and 0.564, respectively) did not differ significantly between those that received TXA versus those that did not. Given the increasing u...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
