为探讨补液时间对烧伤休克复苏的影响，利用电子顺磁共振（ＥＳＲ）技术、丙二醛（ＭＤＡ）及三磷酸腺苷（ＡＴＰ）含量、血乳酸脱氢酶同功酶（ＬＤＨ３）与ＡＴＰ酶（ＡＴＰａｓｅ）活力、肺血管通透性的测定，以及电镜下观察肺部超微结构改变等方法，观察了大鼠烧伤后不补液、立即补液和延迟补液对其肺部损伤情况。发现烧伤后不补液和延迟补液组大鼠肺部受到不同程度损伤，而立即补液则对烧伤大鼠肺部有一定保护作用。作者认为：烧伤休克延迟补液对肺产生的损伤因素是多方面的，氧自由基的损伤起着重要作用。立即补救对肺有一定程度的保护作用，但严重烧伤后的液体复苏中应辅以新的内容
In order to investigate the effect of rehydration time on the recovery of burn shock, the effect of alcohol paramagnetic resonance (ESR) on malondialdehyde (MDA) and ATP content, LDH3 and ATPase ) Vitality and pulmonary vascular permeability, as well as electron microscopic observation of ultrastructural changes in the lungs and other methods to observe the rat after burn without rehydration, immediate rehydration and delayed rehydration on the lung injury. It was found that the lungs of rats that were not rehydrated and delayed rehydration after burn were injured to some extent, while the immediate rehydration had a certain protective effect on the lungs of the burn rats. The author believes that: delayed burn wound shock fluid damage caused by the lungs are many, oxygen free radical damage plays an important role. Immediate relief has some degree of protective effect on the lungs, but fluid recovery after severe burns should be supplemented with new content
