Rapid hemostasis is critical for first-aid of war wound, and the application of tourniquet has always been the primary choice of combat casualties. With the change of battlefield injury form and development of hemostasis concept, the major technique for hemorrhage control has been changing from physical-aid to chemical-aid and bio-aid hemostasis, leading to the invention and application of various novel hemostatic materials and methods. The novel hemostatic techniques based on some special hemostatic agents are characterized by rapidity, convenience, high efficiency, less adverse event and good prognosis; in addition, they are particularly useful when the wounds can not be controlled by the traditional methods, such as internal hemorrhage and coagulopathy. This review summed the advance in hemostatic technology for first-aid of combat casualties, novel hemostatic agents and the related hemostatic products.
