Abstract: Argument. Gunshot wounds are generally examined by assessing the aspect of the traumatic lesions aspect, represented by the destruction produced by the projectile. The injuries produced strictly by gas pressure have been less studied, and the model of a weapon that fires blind cartridges can provide valuable information in this direction. Objective. The purpose of the present work is to analyze the mechanical action of gas pressure in gunshot injuries, distinct from primary injuries, produced by a projectile, in the situation of firing from a short distance, within the range of action of secondary factors of shooting. Material and method. Two pig carcasses were used for the experiment, a gas revolver brand RÖHM RG89 cal. 9 mm. R, blindfolds, a Cannon brand camera and a LEICA microscope. Shootings were performed in different anatomical regions. Results: shots from a centimeter distance produce only epidermal lesions. Shots with glued barrel produce injuries that exceed the level of the skin when they are executed in an area of minimum resistance of the skin. Conclusion. In shooting with blind cartridges, the destructive effect rarely exceeds the surface of the skin, it essentially depends on the shooting distance. In contact gunshot wounds, it is possible to exceed the limit of the dermis, these injuries becoming penetrating, especially at the abdominal level.
Keywords: blind cartridges effect, gaseous pressure in ballistic-induced injuries, shooting effects.
