Is TXA cost effective?
Probabilistic Sensitivity analysis Overall, TXA is likely to be a cost effective intervention even if the willingness to pay for an additional life year saved is as low as $100.
How long does TXA last?
The half-life of TXA is 2 to 11 hours. The duration of action is 3 hours after the initial dose.
What is the Crash 2 trial?
CRASH-2 (Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage 2) is a large placebo-controlled trial of the effects of early administration of a short course of tranexamic acid on death, vascular occlusive events, and the receipt of blood transfusion.
What is permissive hypotension in trauma?
The concept of “permissive hypotension” refers to managing trauma patients by restricting the amount of resuscitation fluid and maintaining blood pressure in the lower than normal range if there is continuing bleeding during the acute period of injury.
How expensive is TXA?
The drug is tranexamic acid (TXA), and it currently costs EMS agencies about $30 a dose. TXA is a generic drug that’s been around for decades, and in fact is sold over-the-counter in Europe and Japan for heavy menses. Delivered via IV to trauma patients, it’s been found to be lifesaving, with no dangerous side effects.

How quickly does oral TXA work?
Following oral administration, about 50 percent of tranexamic acid is absorbed from the gut, reaching peak plasma drug levels in three hours. Intravenous administration results in peak levels within minutes.
What is hypotensive resuscitation?
Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur.
What are the results of the crash 2 trial?
However, in CRASH-2, there were no differences in the rate of vascular occlusive events (1.7% vs. 2.0%). The results of CRASH-2 were concordant with those of the subsequent MATTERs trial (2012). Early administration of 1 gram of tranexamic acid to casualties expected to receive blood transfusions as soon as possible (class I, level B).
What was the crash 2 clinical randomization study?
The 2010 Clinical Randomization of an Antifibrinolytic in Significant Hemorrhage 2 (CRASH-2) was an international study of 20,207 trauma patients with or at risk of significant hemorrhage, defined based on hemodynamic instability. Patients were randomized to double-blind treatment with either tranexamic acid or matching placebo,…
Is the CRASH-2 trial underestimating the benefit of TXA?
On the other hand, there is a chance that CRASH-2 underestimates the benefit of TXA. Death due to bleeding only occurred in about 5% of the population, and this is the only disease specific mortality that TXA reduced.
What was the Fragility Index for Crash 2?
The fragility index for CRASH 2 is 48. That is a reassuring number. However, despite the very small percentage of patients lost to follow-up, CRASH-2 is a massive trial. A total of 84 patients were lost.
