一、颅脑火器伤的特点颅脑火器伤是战时发生率较高的创伤,约占全部战伤的15%,发生率仅次于四肢伤而居第二位。自1979年中越边界自卫还击战以来,我军前方指战员均戴头盔,颅脯火器伤的发生率已有所下降。颅脑火器伤的致伤物中,主要有各种类型的枪弹和弹片。而枪伤伤员的死亡率和致残率却明显地高于弹片伤,这是由于战时使用的各类型枪支与平时的手枪不同,一般均系高速飞射物,每秒均在2,000呎以上。当枪弹击中头部时,由于其能量巨大造成的脑组
First, the characteristics of craniocerebral gunshot wound craniocerebral gunsmilk injury is a higher incidence of wartime trauma, accounting for about 15% of all war injuries, the incidence rate ranks second only to limbs injury. Since the counterattack in self-defense of the border between China and Vietnam in 1979, helmets have been worn by officers and soldiers in front of our army and the incidence of firearm trauma has dropped. There are mainly various types of bullets and shrapnel in craniocerebral gunshot wounds. The death rate and morbidity of gunshot wounds were significantly higher than those of the shrapnel wounds. This is because different types of firearms used in wartime are different from their usual pistols. They are usually flying at high speeds of over 2,000 feet per second . When a bullet hits the head, it becomes brain-shaped due to its huge energy
