The incidence of vascular trauma is increasing in modern warfare, and tourniquets have become the most effective adjuncts to save lives of the wounded by preventing extremity or junctional hemorrhage at the stage of first-line treatment. Due to the complex environment of modern war, tourniquets should be of intelligence, integration, lightweight, miniaturization, reuse, well patient tolerance, strong stability, and low-cost. This review summarizes the research progress on tourniquets, including those recommended by the tactical combat casualty care guidelines, used by the Armed Forces of the Russian Federation and the Chinese People’s Liberation Army, and those currently not included in the guidelines but inspirational for research and development. We also list the advantages and disadvantages of those tourniquets, hoping to provide reference for the development of new tourniquets.
