摘要
目的建立家兔胸部火器伤实验模型，探讨致伤机理及早期死亡原因。方法４８只家兔随机均分为８组，分别用气步枪和小口径步枪致胸壁伤和胸腔伤，并分实验模型组与救治组对比研究。实验中对血压、心率、气道压、血气、胸部Ｘ线等指标进行监测和常规病理检查。结果胸壁伤：模型组中气步枪无死亡，小口径步枪死亡１只，救治组无死亡。胸腔穿透伤：模型组与救治组中气步枪死亡率分别为５０％和１６．７％，小口径步枪分别为８３．３％和５０％。结论（１）按实验参数致伤结果符合量效关系，重复性好，且与人类战时火器伤死亡率近似；（２）发现除心脏、大血管损伤外，肋间动脉出血也是动物早期死亡的重要原因；肺损伤出现早而严重；
Objective To establish a firearm thoracic injury model in rabbit and study on the mechanism of injury and causes of early death. Methods 48 rabbits were divided into two groups randomly:Thoracic wall injury and intrathoracic injury groups.Each group was divided into two subgroups:Simple injury (group of model) and primary treatment after injury(group of treatment ).They were injured with air pressuring rifle (APR,missile mass:0.32g) and small bore rifle (SBR,missile mass:2.57g) respectively at a velocity of 350m/s. There were 8 groups in total and 6 rabbits in each group.The blood pressure,heart rate,airway pressure,blood gas and chest X ray were monitored,and routine pathological examination was done. Results Thoracic wall injury:No mortality in group APR.One died in group of model and no death in group of treatment in group SBR.Intrathoracic injury:The mortality in group of APR ranged from 50% to 16.7% in group of SBR and from 83.3% to 50% with treatment. Conclusion
