The regenerative medicine has made great breakthrough in the repair of combat trauma, showing broad prospects, while the method of regenerative medicine applied in the early treatment of combat trauma is not yet clear. The early treatment of combat trauma includes strict control of bleeding, a large amount of blood transfusion, alleviation of acidosis, and correction of hypothermia and improvement of coagulation dysfunction, etc. This paper focuses on the bio-engineered blood, research and development of homeostatic materials, control of inflammation/infection, regulation of immunity, protection of important organs, establishment of military medical model, research and development of biosensors and drugs, and preventive application of stem cell bank in regenerative and tissue engineering in defense medicine to summarize the role of regenerative medicine in the early treatment of combat trauma, hoping to improve the overall treatment level of combat trauma.
