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=,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%,、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).

Abstract:AIM To investigate the functional changes of the heart and lung resulting from rating thoracic gunshot wound in the dogs and to explore the wound Thirty-five dogs were divided randomly into3grou
ps:Group A was the rating thoracic wounds group(control group),in group B,the intercostal artery was ligat-ed before wound and in group C,the intercostal artery was ligated and artificial pneumothorax was made before wound.
In all the groups,the gunshot wound was made with rifles at the same site point at lower right rate,airway pressure,as well as artery and vein pressure were monitored was performed in all the experimental Mortality rate %in group A,%in group B,and no dogs died in group both group A and B,the respiration rate,pressure peak val-ue of airway soon increased pressure of artery a
