As mentioned in the literature, the lung is one of the most vulnerable organs to blast wave.Severe blast injury of the lung is always one of the causes of death in persons suffering from blast injuries. In an effort to clarify early changes of pulmonary function after blast injury, the following experiment was made:Thirty-four male adult mongrel dogs weighing from 15 to 20 kg were exposed to 40 kg of TNT charge in an open area. The distance from the animals to the charge was 7.5 meters. After explosion,...

As mentioned in the literature, the lung is one of the most vulnerable organs to blast wave.Severe blast injury of the lung is always one of the causes of death in persons suffering from blast injuries. In an effort to clarify early changes of pulmonary function after blast injury, the following experiment was made:Thirty-four male adult mongrel dogs weighing from 15 to 20 kg were exposed to 40 kg of TNT charge in an open area. The distance from the animals to the charge was 7.5 meters. After explosion, most of the experimental animals suffered from more than moderate blast injuries.Arterial and venous blood of the animals were drawn for pulmonary shunt (in 13 dogs), PO2, PCO2, HCO-3 and BE(in all dogs) before and eight to forty-eight hours after explosion. The results showed that pulmonary shunt increased to 21.6% eight hours after injury (4.7% before explosion). The difference between them was very significant (P<0.001). 48 hours after injury, the pulmonary shunt decreased to 9.6%, which was still higher than that of pre-explosion level, but the difference between the two was statistically insignificant (P>0.05). Other parameters did not show any significant changes 8, 24 and 48 hours after explosion, except a slight decrease in PO2.From the results mentioned above, it can be suggested that the pulmonary shunt is a more sensitive index for diagnosing blast injury of the lung.

本文报告了用TNT炸药爆炸致伤的34只冲击伤狗,伤后肺分流量和血气等方面的变化。观察表明,动物在伤后8小时,肺分流量平均由伤前的4.7%增至21.6%,差别非常显著(P<0.001);伤后48小时,已降至9.6%,与伤前相比,差别已不显著(p>0.05)。致伤后8、24、48小时所作的PaO_2、PaCO_2、HCO_3~-,BE和pH等项检查表明,除PaO_2伤后有一些降低外,其余变化均不明显。我们认为,肺冲击伤时,肺分流量的变化较PaO_2等指标更为敏感,并可在很大程度上反映出肺损伤的伤情,因而有一定的诊断价值。

The lung is known as one of the 'target' organs to the effect of blast wave.

In addition, the relation between overpressure and che degree of blast injury to the lung is also describ-ed. The main pathological alterations in the lung were various degrees of hemorrhage, edema, rupture and large air bubble formation,and,in the next place, hyperaemia, atelectasis, emphysema and secondary...

The lung is known as one of the 'target' organs to the effect of blast wave. This paper describes the pathology of blast injuries to the lungs in forty-three dogs inflicted with explosion of TNT charge. In addition, the relation between overpressure and che degree of blast injury to the lung is also describ-ed. The main pathological alterations in the lung were various degrees of hemorrhage, edema, rupture and large air bubble formation,and,in the next place, hyperaemia, atelectasis, emphysema and secondary bronchitis. Parallel strips of pulmonary hemorrhage corresponding to the intercostal spaces formed the characteristic feature. On the basis of gross and microscopical observations, the mechanism of the injuries has been discussed.

(1)本文报告了TNT炸药爆炸条件下,43只狗肺冲击伤伤情与超压峰值的关系、肺损伤的发生情况和伤后1~8天间肺的病理改变。(2)实验结果表明,造成不同程度肺损伤的超压(入射压/反射压)阈值依次为:轻度——0.35/0.45、中度和重度——0.73/0.78、极重度——1.03/1.21kg/cm~2。中度以上各级肺损伤的致伤压力阈值与同级的全身损伤压力阈值相同。就各种肺损伤的超压阈值而言,肺出血最低,肺破裂最高。(3)肺的主要病变为出血、水肿、大疱形成和肺破裂,其次为充血、萎陷、气肿及继发感染。对肺出血和肺水肿的发生机理作了讨论。

How to use intravenous fluid therapy safely in patients with combined burn-blast injuries is an unsolved problem. Therefore, this experimental study was carried out in 64 dogs with combined injuries of 40% second degree burns (inflicted with nalpam) and moderate or severe blast injury (inflicted with TNT charge explosion) . Intravenous infusion was administered as early as 6-8 hours after injury. The amount was 0.5 ml colloid and 1-1.5 ml crystal solution/kg of body weight/one percent of body surface burns...

How to use intravenous fluid therapy safely in patients with combined burn-blast injuries is an unsolved problem. Therefore, this experimental study was carried out in 64 dogs with combined injuries of 40% second degree burns (inflicted with nalpam) and moderate or severe blast injury (inflicted with TNT charge explosion) . Intravenous infusion was administered as early as 6-8 hours after injury. The amount was 0.5 ml colloid and 1-1.5 ml crystal solution/kg of body weight/one percent of body surface burns in the first 24 hours after injury, and a half of this amount was given in the second 24 hours. The transfusion of the fluid was finished within 3-5 hours. Another amount 30% of the total amount of the fluid intravenously infused was added as drinking water.It was found that there was no significant difference between the infused animals and the controls so far as the pulmonary pathological changes (including pulmonary edema) were concerned. It is believed that a reasonable amount of intravenous fluid can be safely given to patients with combined burn-blast injuries provided that the changes of the urinary output and the physical signs of the chest are carefully monitored.

1.本文报告了狗40%Ⅱ~-~Ⅱ~+烧伤合并中度以上肺冲击伤时,早期静脉输液对肺部的影响。共用122只狗,有相应烧冲、单烧、单冲对照组。 2.实验结果表明,按临床输液公式较晚而较快地静脉补给液体,未见有肺出血加重,肺水肿的发生率和中度以上的比例虽较对照组略高,但差别无统计学意义。 3.据实验结果,结合临床资料,认为在烧冲复合伤时,在监测尿量和胸部体征变化的条件下,应补充足量的液体。
