【摘要】：目的探索多舱室爆炸比格犬的致伤特点并进行伤情分析。方法健康成年雄性比格犬48只,分别置于当舱和邻舱(n=24),于装药量为0.75kg和3.50kg TNT的舱室(当舱)进行静爆,观察爆后即刻至伤后24h动物存活情况、各项生命体征的改变、脏器形态学改变及各种致伤类型的发生率,并进行神经功能评分。结果比格犬现场死亡20只,伤后24h内死亡9只,死亡发生率为60.42%(29/48),其中当舱死亡发生率为79.17%(19/24),邻舱死亡发生率为41.67%(10/24)。形态学改变主要表现为颅骨弹片穿通伤,脑组织以及肺、心、胃肠道、肝、肾等器官不同程度淤血和出血,软组织挫伤或体腔破裂缺损,肢体断离缺失,肢体骨折,严重者甚至发生空腔和实质脏器穿孔或破裂。破片伤、冲击波伤与冲击波破片复合伤的致死率分别为27.59%(8/29)、17.24%(5/29)和55.17%(16/29)。结论舱室内爆炸性武器所致破片伤与冲击波复合伤具有发生率高、伤情重、致死率高等特点,应尽可能地寻找遮挡物体,从而减少被杀伤的机会,进而降低死亡发生率。其早期救治的重点是及时有效地处理多发伤;液体复苏时最好在血流动力学监测条件下进行,以免进一步加重病情。
[Abstract]:Objective to explore the injury characteristics of multi-compartment explosive Beagle and analyze the injury condition.Methods 48 healthy adult male Beagle dogs were placed in the cabin and adjacent cabin respectively, and were detonated in the cabin containing 0.75kg and 3.50kg TNT. The survival of the animals was observed immediately after the explosion and 24 hours after the injury, and the changes of the vital signs were observed.Morphological changes of organs and incidence of various types of injury, and neurological function score.Results 20 Beagle dogs died in the field, 9 died within 24 hours after injury, and the death rate was 60.42%. The mortality rate of the second compartment was 79.17 / 19 / 24, and that of the adjacent cabin was 41.67 / 24 / 10 / 24.The main morphological changes were skull shrapnel puncture injury, brain tissue and lung, heart, gastrointestinal tract, liver, kidney, and other organs of different degrees of congestion and bleeding, soft tissue contusion or body cavity rupture defect, limb broken loss, limb fracture,In severe cases, the cavity and parenchyma organ even perforated or ruptured.The fatality rates of fragment injury, shock wave injury and blast wave fragment combined injury were 27.599 / 29 and 17.24 / 29, respectively, and 55.17% of 16 / 29 respectively.Conclusion the compound injury caused by explosive weapons in cabin has the characteristics of high incidence, serious injury and high mortality. It is necessary to look for occluded objects as far as possible so as to reduce the chance of being killed and then reduce the incidence of death.The emphasis of early treatment is to deal with multiple injuries in time and effectively, and fluid resuscitation is best carried out under the condition of hemodynamic monitoring, so as to avoid further exacerbation of the disease.
