The aim of this study was to elucidate the clinical characteristics of the injury and to present our clinical experiences on the treatment of such cases.Methods Five patients with severe bum-blast combined injuries were admitted to our hospital 77 hours post-injury on June 7, 2005. The burn extent ranged from 80% to 97% （89.6%±7.2%） of TBSA （full-thickness burns 75%-92% （83.4%±7.3%））. All the patients were diagnosed as having blast injury and moderate or severe inhalation injury. Functions of the heart, liver, kidney, lung, pancreas and coagulation were observed. Autopsy samples of the heart, liver, and lungs were taken from the deceased. Comprehensive measures were taken during the treatment, including protection of organ dys function, use of antibiotics, early anticoagulant treatment, early closure of burn wounds, etc. All the data were analyzed statistically with t test.Results One patient died of septic shock 23 hours after admission （four days after injury）, the others survived. Dysfunction of the heart, liver, lungs, pancreas, and coagulation were found in all the patients on admission, and the functions were ameliorated after appropriate treatments.Conclusions Burn-blast combined injury may cause multiple organ dysfunctions, especially coagulopathy. Proper judgment of patients＇ condition, energetic anticoagulant treatment, early closure of burn wounds, rational use of antibiotics, nutritional support, intensive insulin treatment, timely and effective support and protection of organ function are the most important contributory factors in successful treatment of burn-blast combined injuries.展开更多
研究了一次引爆云爆剂(SEFAE—single event fuel air explosive)的后燃反应(after-burning)及对其爆炸波威力的影响。通过高速摄像的记录对战斗部爆炸过程进行了分析,根据对SEFAE战斗部爆炸场参数的测试,以及爆炸威力的TNT当量计算,对...研究了一次引爆云爆剂(SEFAE—single event fuel air explosive)的后燃反应(after-burning)及对其爆炸波威力的影响。通过高速摄像的记录对战斗部爆炸过程进行了分析,根据对SEFAE战斗部爆炸场参数的测试,以及爆炸威力的TNT当量计算,对战斗部壳体破裂后SEFAE所释放的能量进行了定量分析,并同试验结果进行了对比。发现强烈的后燃反应使SEFAE爆轰总能量和爆炸威力较普通炸药有很大的提高。并探讨了壳体破裂后SEFAE与空气中氧的作用机理,提出了提高云爆剂威力的途径。展开更多
