[Simulated experiment of hemodynamics changes in aorta during high energetic trauma through abdomen].

In order to study the mechanism of remote effect of missile wound, we designed and carried out a simulated experiment. The change of hemodynamics in aorta was examined with a pressure transducer during gunshot and then calculated. The results revealed superhigh pressure, high speed of pressure rising, accelerated velocity of blood flow, substantial pressure difference and profuse blood flow in aorta during gunshot.
