摘要
目的:探讨冲击波致伤及爆炸性武器破片防护作用中战壕的意义。方法:实验动物为山羊26只,其中战壕组12只,开阔地组14只,分别布放于距爆心10m和15m的战壕及开阔地,某型炸弹置于地面,用电雷管引爆,先后共进行3次,观察伤后18h动物的活存情况,体表和内脏损伤情况。结果:战壕组距爆心10m的活存率为1/5,距爆心15m的活存率为7/7,而开阔地组距爆心10m的活存率为0/5,距爆心15m的活存率为1/9;战壕组均未被破片击中,而开阔地组均被破片击中;战壕组距爆心10m的动物可见严重的冲击伤,主要表现为严重的肺出血和肺水肿,而距爆心15m的战壕仅个别动物有轻、中度肺出血,开阔地组动物可因破片和冲击波的作用,引起严重的体表和内脏损伤,表现为肢体毁损、胸腹腔开放伤、肢体离断骨折、内脏器官破裂缺损等。结论:战壕可有效防止爆炸性武器破片引起的损伤,对距爆心一定距离的冲击波致伤也有较好的防护效果。
AIM:To explore the protective effects of entrenchment in fragments and blast injury caused by explosive weapons. METHODS: Twenty six goats were divided into 2 groups:12 in entrenchment group and 14 in open land group.They were distributed in the entrenchment and open land around the explosive point with the radius of 10 and 15 meters.A bomb was detonated on the ground and this explosion was repeated 3 times.Then the survival proportion and macro morphological changes were carefully recorded 18 hours after injury. RESULTS:The survival proportion in the entrenchment group was 1/5 and 7/7 corresponding to the 10 m and 15 m radius.The survival proportion in the open land group was 0/5 and 1/9 corresponding to the 10 m and 15 m radius. No goats in the entrenchment group, but all goats in the open land group, were hit by fragments. The animals distributed 10 m beyond the explosive center in the entrenchment group appeared severe blast injuries, showed as severe lung hemorrhage and edema, however, very few animals among those distributed 15 m beyond the explosive center in the same group showed mild and moderate injuries. The animals in the open land group, acted by fragments and blast wave, had severe body surface and viscera injuries which included limb mutilation,fracture or breakaway, thoracic and abdominal open injuries,viscera rupture or defection, etc. CONCLUSION:Entrenchment can prevent the fragment injuries caused by explosive weapons effectively.It is also preferred in the protection of blast injuries which occur some distance to explosive center.
