摘要 目的:研究嵌顿疝患儿血浆中二胺氧化酶(diamine oxidase,DAO)及肠脂肪酸结合蛋白(intestinal fatty acid binding protein,I-FABP)在不同嵌顿时间段的变化情况及对预测嵌顿肠管血运情况的价值。方法:收集临床资料,分为嵌顿疝组和对照组,嵌顿疝组收集32例嵌顿疝患儿术前30 min血标本,其中非肠切组22例与肠切组10例,肠切组标本送病理诊断,另外对照组收集腹股沟斜疝患儿血标本10例。离心提取上层血清,采用酶联免疫吸附法测定样品血清中DAO和I-FABP的浓度。结果:嵌顿疝组与对照组相比,DAO、I-FABP水平明显提高(P <0.05)。DAO、I-FABP水平随着嵌顿的进展有明显增高,呈正相关(P <0.05)。肠切组患儿的DAO、I-FABP水平与非肠切除组相比,均有明显提高(P <0.05)。DAO>27.10 U/mL时,诊断考虑肠管处于濒临坏死或坏死状况的灵敏度为70.0%,特异度为95.5%;I-FABP>1 654.50 ng/L时,诊断考虑肠管处于濒临坏死或坏死状况的灵敏度为90.0%,特异度为86.4%。结论:小儿嵌顿疝中,血浆中的DAO与I-FABP水平有着明显的时间依赖性,且能相对较敏感地反映实际肠管血运情况,特别对于早期了解嵌顿疝患儿肠管缺血情况有较大帮助,能为临床医师的治疗措施提供证据。
