摘要
目的:在法医鉴定中,常遇到因过量输液引发循环超负荷致死案例,本研究探讨不同输液量救治失血性休克过程中对心脏及其心钠素(Atrial natriuretic peptide,ANP)表达的影响。方法:成年家兔分对照组、模型组(失血性休克)、常规组(失血性休克常规输液)、观察组(失血性休克大量输液),7只每组,建立失血性休克模型,动态监测生命体征、心肌HE染色、ANP的免疫组化染色并使用图像分析技术定量心肌间隙总面积和ANP表达情况。结果:各组心肌间隙不同程度水肿,观察组HE染色心肌间隙总面积、ANP免疫组化表达均高于其他组(P<0.05)。结论:失血性休克过量输液加重心脏负荷,引起心肌损害,增加死亡风险。
Objective In forensic identification,the cases of cyclic overload caused by excessive infusion are often encountered. This study was to investigate the effect of different infusion volumes on the expression of atrial natriuretic peptide（ ANP） during the hemorrhagic shock.Methods Adult rabbits were divided into control group,model group（ hemorrhagic shock）,conventional group（ hemorrhagic shock conventional infusion）,observation group（ heavy hemorrhagic shock,large infusion）,7 rabbits in each group.The established hemorrhagic shock model was established on all rabbits. Dynamic monitoring of vital signs,myocardial HE staining,immunohistochemical staining of ANP and image analysis technique were used to quantify the total area of myocardial interstitial and ANP expression.Results There were different degrees of edema in each group. The total area of HE stained myocardial interstitial and the immunohistochemical expression of ANP were higher in the observation group than in the other groups（ P〈0.05）.Conclusion Excessive infusion of hemorrhagic shock aggravates cardiac burden,causes myocardial damage,and increases the risk of death.
