Abstract

Experiments with armoured vest on mongrel dogs and mini-pigs showed that the most significant indices of contusion trauma is the volume of injury. When the shock impulse affects the cardiac zone the inner organs injuries are distributed in the following way: right lung - 29%o, right lung + liver - 29%o, left lung + liver -14%o, right lung + heart - 14%o, heart + liver - 14%o, and cardiorrhexis occurs only in 32%o of cases. When the shock impulse is aimed at the pulmonary zone the isolated liver injury is observed in 54%o and combined injury of the right lung and liver in 46%> of cases. The severity of the contusion trauma resulting in liver and spleen injuries may be of different degree. In such cases the outcome depends on the type and severity of these organs injury and inner bleeding may be asymptomatic for a long time. The results of our study show that even the first 6 hours after the spleen injury the volume of blood within the abdomen could be from 500 to 1000 ml. At the same time the ruptures and fissures of the hepatic capsule do not result in such massive hemorrhage.
