摘　　要：目的研究家兔正碰交通伤的损伤机制和伤情特点。方法30只家兔根据碰撞初速度不同分为3组,Ⅰ组(30km/h),Ⅱ组(40km/h),Ⅲ组(50km/h)。以坐姿固定家兔于动物固定台车上,按预先设置速度和加速度启动动力牵引系统开始致伤过程。用激光测速系统和高速摄像系统测量和分析碰撞瞬间动物固定台车的速度和减速度。观察致伤后动物的伤情特点,对家兔作大体解剖并进行AIS-ISS评分。结果伤后1h内Ⅱ组死亡1只兔子,Ⅲ组死亡3只兔子,其余动物均存活。Ⅰ组未见明显脏器损伤,Ⅱ、Ⅲ组家兔损伤部位为胸腹部,AIS(MAIS)和ISS评分分别是(2.30±0.65)、(14.50±2.10)、(4.20±0.70)、(36.40±4.58)。结论碰撞初速度和减速度对动物的伤情有影响,胸腹部是兔正碰交通伤的主要损伤部位。Objective To study the mechanism and characteristic of traffic injury of front crash. Methods Thirty rabbits were divided randomly into 3 groups according to crash velocity. The initial velocity of Group Ⅰwas 30 km/h, group Ⅱ40 km/h, and groupⅢ50 km/h. The rabbits were fixed on the seats in a sitting position and the injury process were started by driving power system with the velocity and acceleration set primarily. The crashing velocity and deceleration were recorded by laser velocity measuring system and high speed camera system. The injury characteristics of rabbits were observed and then the AIS-ISS score was compared. Results During 1 hour after injury, all rabbits survived except one in group Ⅱ and three in group Ⅲ. No organ injury was found in groupⅠ , but organ injuries in thorax and abdomen were found in group Ⅱ and Ⅲ. The score of AIS （MAIS） and ISS were （ 2.30 ± 0.65 ）, （ 14.50 ± 2.10） in group Ⅱ and （4.20 ± 0.70）, （ 36. 40 ± 4.58 ） in group Ⅲ respectively. Conclusion The velocity and deceleration of crash have impact on the injury character of animal, and the main injury organs are the thorax and abdomen in traffic injury of front crash in rabbits.
