In Russia, drugs have been developed to help stop dangerous bleeding faster with severe injuries, complex surgeries and complications during childbirth, sometimes minutes count. In such situations, it is important for doctors not only to resume blood loss, but also to help the body stop the bleeding. Two new drugs appeared in Russia, including for emergency use. They contain proteins that help the blood to clot and form a clot that closes the damaged vessel. In the same volume of these preparations, there are four times more such proteins than in a special plasma of dried blood. The main advantage of the new products is that they are produced dry: water is removed in a special way, so that the drugs can be stored at temperatures of +5 to +20 degrees, without freezing. This simplifies their use in emergency situations: doctors do not have to wait for the shipment of frozen material and make complex preparations before use.
