The side effects were to dangerous and we know that from beginning.You can controll EVERY outer bleeding by pressing a dressing on it.
Using a tourinquet to stop a bleeding is not a regular treatment!!!! You will squeeze all blood vessels, nerves etc. and the patient may lose his arm/leg etc. for sure! A tourniquet is a "ultima ratio" (last resort) only means, you can use it if the patient will die for sure if you don´t do it. Not even a cut off arm nor leg will need a tourniquet! You can controll the bleeding with a regular bandage too - you just need to know how
I´m a professional paramedic for 13 years now. I never ever had to use a tourniquet yet. In the first moment, the musle layer in an artery will contract and close the artery. Thats the time to tie a bandage. If the artery will relaxe and start bleeding, press on the artery on a proximal point. That stops every bleeding too.
Don´t use a tourniquet careless!
Beeing in combat under fire is something different - but nobody over here is
