【摘要】：目的　研究榴彈致胸部創(chuàng)傷的特點(diǎn)和規(guī)律 ,為胸部爆炸傷的救治提供依據(jù)。方法　用電啟動(dòng)引爆離地面 7m高的榴彈 ,將 36只綿羊布放于距爆心 6～ 4 8m處 ,致傷時(shí)測(cè)量沖擊波超壓和破片速度 ,致傷后進(jìn)行病理解剖觀察。結(jié)果　胸部破片傷的發(fā)生率為 4 4 .4 4 % ,傷后即刻死亡率為 31.2 5% ,傷后 6h時(shí)達(dá)56.2 5% ,以后增加不明顯 ;盲管傷、貫通傷和切線傷的發(fā)生率分別為 2 2 .2 2 %、16.67%和 5.56% ;肺沖擊傷的發(fā)生率為 55.55% ;心臟被直接擊中的機(jī)率為 5.56% ;肋骨骨折嚴(yán)重 ,胸腔積血多 ,分占胸部創(chuàng)傷動(dòng)物的 31.2 5%和 87.5%。結(jié)論　破片擊中胸部的機(jī)率高 ,胸壁穿透?jìng)?,傷情嚴(yán)重 ,多在傷后 6h以內(nèi)死亡 ;肺臟不但可被破片直接擊中 ,也以更高的比例發(fā)生沖擊傷。因而救治時(shí)不僅要早 ,也要注意檢查和處理肺沖擊傷。
[Abstract]:Objective to study the characteristics and regularity of chest trauma caused by grenade, and to provide evidence for the treatment of chest explosion injury. Methods 36 sheep were placed in the distance of 6 ~ 48 m from the explosion center. The overpressure of shock wave and the velocity of fragment were measured during the injury, and the pathological anatomy was observed after the injury. Results the incidence of chest rupture injury was 44.44%, the immediate mortality rate was 31.25%, and the mortality rate was 52.25% at 6 h after injury, but the increase was not obvious in the future. The incidence of blind tube injury, penetrating injury and cut line injury was 22.22%, 16.67% and 5.56% respectively, the incidence of lung blast injury was 5555%, and the probability of heart being hit directly was 5.56%. The fracture of ribs was serious and there was a lot of bleeding in chest cavity, accounting for 31.25% and 87.5% of the animals with chest trauma. Conclusion the probability of fragment hitting the chest is high, the penetrating injury of chest wall is more, the injury is serious, and most of them die within 6 hours after injury, and the lung can not only be hit directly by fragment, but also have impact injury in a higher proportion. Therefore, the treatment should not only be early, but also pay attention to the examination and treatment of lung impact injury.
