| 摘 要： | 用蒸气吸入性损伤犬模型,对其伤前、伤后呼吸和循环动力学的早期变化进行了观察比较,旨在为临床应用提供依据。结果发现:致伤后呼吸系统总阻力逐渐上升(3小时和4小时 P<0.05);呼吸系统总顺应性在伤后3小时,肺顺应性在伤后4小时均显著下降(P<0.05);在伤后2小时,心率非常显著地减少(P<0.01),心输出量显著降低(P<0.05)。提示蒸气吸入性损伤后,早期就发生呼吸和循环动力学的变化。早期检测这些指标,有助于及时诊治吸入性损伤。

| Abstract: | Early changes in respiratory and circulatory dynamics before and after steam-inhalation injury were made in a dog model were studied.The results showed that the resistance of the respiratory system was significantly higher 3 hours and 4 hours post injury than that before injury(P<0.05),the compliances of both the lung 4 hours post-injury and the respiratory system 3 hours psot-injury signifi- cantly decreased(P<0.05),and the heart rate markedly lowered(P<0.01),and the cardiac output al- so decreased(P<0.05)2 hours after injury.It is suggested that the early changes in the respiratory and circulatory dynamics may be used as markers for the diagnosis and treatment of the inhalation injury. |
