Drug May Help EMTs Save Lives

An old drug being used for new purpose.
A drug that's been around for decades is being used in a new way to potentially save lives. Tranexamic acid or TXA was primarily used before heart surgeries. Now, some first responders are using it at accident scenes to help blood clot faster.
Emergency responders give the drug when it's determined that a victim is in danger due to bleeding.
Researchers say extensive worldwide studies found that TXA doesn't cause any significant side effects. One study shows that for every use, it can save at least one out of seven lives.
