Abstract:
Remote effect is one of the most important characteristics of high-velocity projectiles. It is the basic way to explore its mechanism in the changes of hemodynamic. Our experiments were desingned to observe the hemodynamic changes in 10 pigs with abdomen trauma caused by 6.35ram 1.03g high-velocity steel balls. The results showed that at one hour after trauma the level of cardiac output (CO), stroke volume (SV), left ventricle stroke work (LVSW) and mean artery pressure (MAP) decreased significantly, however, the level of pulmonary capillary wedge pressure (PCWP) increased significantly. At 8 hour after trauma, CO, SV, LVSW, MAP began to increase and PCWP began to declined slowly. At 72 hour after trauma the changes were close to the pretrauma values. From the experiments we also found that the hemodynamic changes were related to the heart injuries caused by remote effect.
