Body armor is used by military personnel, police officers, and security guards to protect them from fatal gunshot injuries to the thorax. The protection against high-velocity weapons may, however, be insufficient. Complementary trauma attenuating backings (TAB) have been suggested to prevent morbidity and mortality in high-velocity weapon trauma.
Twenty-four Swedish landrace pigs, protected by a ceramid/aramid body armor without (n = 12) or with TAB (n = 12) were shot with a standard 7.62-mm assault rifle. Morphologic injuries, cardiorespiratory, and electroencephalogram changes as well as physical parameters were registered.
The bullet impact caused a reproducible behind armor blunt trauma (BABT) in both the groups. The TAB significantly decreased size of the lung contusion and prevented hemoptysis. The postimpact apnea, desaturation, hypotension, and rise in pulmonary artery pressure were significantly attenuated in the TAB group. Moreover, TAB reduced transient peak pressures in thorax by 91%.
Our results indicate that ordinary body armor should be complemented by a TAB to prevent thoracic injuries when the threat is high-velocity weapons.
军事人员、警察和保安人员使用防弹衣来保护胸部免受致命枪伤。然而，防弹衣对高速武器的防护作用可能不足。有人建议使用辅助创伤减轻衬垫（TAB）来预防高速武器创伤导致的发病和死亡。
用标准的7.62毫米突击步枪射击24头瑞典长白猪，其中12头猪仅穿着陶瓷/芳纶防弹衣，另外12头猪穿着带有TAB的陶瓷/芳纶防弹衣。记录形态学损伤、心肺和脑电图变化以及身体参数。
两组猪均出现了可重复性的防弹衣后钝性创伤（BABT）。TAB显著减小了肺挫伤的面积并预防了咯血。TAB组冲击后呼吸暂停、血氧饱和度降低、低血压和肺动脉压升高的情况均得到显著缓解。此外，TAB使胸部的瞬态峰值压力降低了91%。
我们的结果表明，当面临高速武器威胁时，普通防弹衣应辅以TAB以预防胸部损伤。
