【摘要】：目的　研究高能战斗部 (HEF)致胸部伤特点和规律 ,为胸部爆炸伤的救治提供原则和依据。　方法　用电启动的方式引爆HEF ,将 45只绵羊布放于距爆心 30～ 2 40m处 ,致伤时测量冲击波超压和破片速度 ,致伤后进行病理解剖观察。　结果　胸部破片伤的发生率为 6 7% (30 /45 ) ,伤后即刻死亡率为 73% ;损伤类型以盲管伤和贯通伤为主 ,分别为 5 7%和 31% ;在 30只有胸部破片伤的动物中 ,肺冲击伤、肋骨骨折、大量胸腔积血 (10 0 0ml)及胸腹联合伤的发生率分别为80 %、33%、2 7%和 33% ,心脏被直接击中的概率为 33 %。　结论　破片击中胸部的概率高 ,胸壁穿透伤多 ,伤情严重 ,伤后多迅速死亡。胸部严重毁损、心脏破片伤、多脏器受损以及快速失血是其主要死亡原因。
[Abstract]:Objective to study the characteristics and regularity of chest injury caused by high energy warhead (HEF), and to provide the principle and basis for the treatment of chest explosion injury. Methods 45 sheep were placed 30 ~ 240 m away from the explosion heart by detonating HEF by means of electric starting. Shock wave overpressure and fragment velocity were measured at the time of injury, and pathological anatomical observation was carried out after injury. results the incidence of chest fragment injury was 67% (30 / 45), and the immediate mortality after injury was 73%. The main types of injury were blind tube injury and penetrating injury, which were 5.7% and 31%, respectively. In 30 animals with only chest fragment injuries, the incidence of lung shock injury, rib fracture, massive thoracic hemorrhage (100 0ml) and combined thoracoabdominal injury was 80%, 33%, 2.7% and 33%, respectively. The probability of the heart being hit directly is 33%. Conclusion the probability of the fragment hitting the chest is high, the penetrating injury of the chest wall is more, the injury is serious, and most of them die quickly after the injury. Severe chest damage, heart fragment injury, multiple organ damage and rapid blood loss were the main causes of death.
