Abstract: Pain is one of the main post-injury complications in the war, which may induce serious physical and psychological consequences. Recently, more and more attention has been paid to the development of self-aid analgesia for battlefield use in our military medical department. However, equipment for battlefield analgesia in our army still falls behind as compared to those in foreign armies. Meanwhile, battlefield first-aid and analgesia are undergoing rapid development in the US army. Therefore, it is of significant importance to understand the advances in battlefield analgesia home and aboard, in order to improve it for our army.
