| 目的 探讨动物受水下冲击波作用后的胸部X线改变。方法 清醒状态的家兔61只,置于水下2 m或6 m处,使用50 g和500 g两种不同当量球形TNT炸药引爆形成冲击波后,观察动物胸部X线改变,并与组织病理对照。结果 水下冲击波作用引起动物胸部损伤的X线表现为肺挫伤(52/61)、肺撕裂伤(38/61)、肺血肿(32/61)、血气胸(31/61)、膈肌破裂(5/61)等;病理表现肺出血(56/61)、血栓形成(33/61)、肺撕裂(35/61)、肺内血肿形成(32/61)、膈破裂(5/61)。相同实验条件下,不同当量的爆炸物与冲击波致机体损伤的程度有很大差别,这些差别与动物在水中承受的爆炸冲量、能流密度大小及所处的水深有关。结论 胸部X线检查可较为客观、准确地评价水下冲击波对动物胸部损伤的性质及程度。 |

| Objective To observe chest X-ray changes of rabbits injuried by underwater shock wave. Methods Sixty-one rabbits were placed 2 m or 6 m underwater with consciousness. Thoracic injuries model rabbits were established by 50 g and 500 g TNT spherical explosives with different equivalent. Comparison with pathological findings, chest X-ray changes of rabbits were observed. Results Chest X-ray changes of rabbits with thoracic injuries included lung contusion (52/61), pulmonary laceration (38/61), hematoma (32/61), hemapneumothorax (31/61) and diaphragm rupture (5/61). Pathological manifestations included scattered bleeding of alveoli (56/61), formation of thrombosis of small pulmonary artery and vein (33/61), pulmonary laceration (35/61), hematoma (32/61), diaphragm rupture (5/61). Body injury varied with different equivalents of explosive and shock wave in same experimental conditions. The changes were related to explosion impact borne by the rabbits in water, density of energy flow and depth of water. Conclusion Chest X-ray can objectively and accurately evaluate the chest injury of rabbits caused by shock wave underwater. |
