[Abstract]:Objective to establish a canine model of thoracic gunshot injury, and to investigate the causes of early death and the effect of early treatment. Methods Thirteen mongrel dogs were injured by standard small-caliber rifle bullets. The patients were randomly divided into two groups: the model group (n = 7) and the early treatment group (n = 6). The injury parameters were measured. The dynamic changes of respiration and circulation and pathological changes were observed. Results there was no difference in injury parameters between the two groups. 6 cases (86%) died in the model group, 4 cases died of massive thoracic hemorrhage. 2 cases died of respiratory failure, 5 cases died (83%) in the treatment group, 3 cases mainly suffered from massive thoracic hemorrhage. The other two cases died of respiratory failure and femoral artery blood loss, respectively. The mean survival time of the dead dogs after injury was 52 min in the model group. Conclusion 1 Thoracic bullet can be established according to the parameters of injury in this group.
