【摘要】：目的　探讨水下冲击波致腹部脏器损伤的病理形态学改变。方法　成年杂种犬 6 1只 ,用 2 0 0 g、5 0 0 g和 10 0 0 g的三硝基甲苯 (TNT)水下爆炸致水下冲击伤 ,美国 PCB公司水下爆炸压力传感器测定冲击波物理参数 ,观察伤后 6 h腹部脏器损伤的形态学改变。结果　水下冲击波物理参数的特征表现为高的峰值压力 ,正向作用时间较短 ,冲量较大。形态学观察发现胃肠道损伤发生率高 ,其发生率为 6 2 .30 % ,主要表现为胃肠道浆膜和黏膜下不同程度的出血 ,部分动物可见浆肌层撕裂 ,浆膜下血肿 ,甚至发生胃肠道穿孔 ;肝、脾等实质脏器也可发生不同程度的损伤 ,如包膜下出血、血肿和破裂 ,但发生率较低 ;含液脏器 ,如胆囊和膀胱未见明显损伤。结论　水下冲击波可致腹部多脏器损伤 ,胃肠道损伤发生率高、程度重 ,是水下冲击伤早期救治的重要环节之一。
[Abstract]:Objective to investigate the pathomorphological changes of abdominal viscera injury induced by underwater shock wave. Methods Sixty-one adult mongrel dogs were subjected to underwater blast injury induced by underwater explosion with 200 g or 1000 g trinitrotoluene trinitrotoluene (TNT). The physical parameters of shock wave were measured by PCB underwater explosion pressure sensor, and the morphological changes of abdominal viscera injury were observed 6 hours after injury. Results the physical parameters of underwater shock wave were characterized by high peak pressure. The positive action time was shorter and the impulse was larger. Morphological observation showed that the incidence of gastrointestinal injury was high (62.30%), and the main manifestations were bleeding in the serous membrane and submucous membrane of the gastrointestinal tract. In some animals there were tears of the sarcoplasmic muscular layer subserous hematoma and even gastrointestinal perforation liver spleen and other parenchymal organs could also be damaged in varying degrees such as subcapsular hemorrhage hematoma and rupture but the incidence was low. Conclusion underwater shock wave can cause abdominal multiple organ injury, the incidence of gastrointestinal injury is high and the degree of gastrointestinal injury is serious, it is one of the important links in the early treatment of underwater blast injury.
