    摘 要:目的 观察犬穿透性胸部枪弹伤对心肺功能的影响，并探讨其损伤机制. 方法 35只犬随机分为3组，A:胸部穿透伤组(对照组n=12)、B:预扎肋间血管后致伤组n=16、C:预扎肋间血管加人工气胸后致伤组n=7.以上3组分别用*****定点致伤右下胸，连续监测呼吸、气道压、动静脉压等，观察动物死亡情况. 结果 A组死亡率为83%，B组死亡率为38%，C组无死亡.A、B组致伤后呼吸频率、气道压峰值立即明显增高，动、静脉压亦短暂性地显著升高，但仅一个波峰，随即恢复到正常水平，C组无明显变化. 结论 胸部枪弹穿透伤由于心肺功能改变较重，迅即导致了循环、呼吸障碍，死亡率高，死亡原因主要为失血性休克和急性呼吸窘迫综合征(ARDS).
