【摘要】 目的:探讨血浆D-二聚体在早期诊断急性肠系膜缺血中的应用价值。方法:成年雄性Wistar大鼠48只随机均分为实验组和对照组,实验组结扎肠系膜上动脉建立肠系膜动脉缺血模型,对照组仅行开腹手术,1h、6h、12h后分别抽血检测血浆D-二聚体和其他生化指标。结果:实验组中随肠系膜缺血时间的延长,血浆D-二聚体水平越高,实验组和对照组有显著性差异有统计学意义(P<0.05)。其他实验室指标实验组和对照组差异无统计学意义。结论:动态测定血浆D-二聚体可能对早期筛选急性肠系膜缺血具有重要价值。更多还原

【Abstract】 Objective:In this study we evaluated the diagnostic value of plasma D-dimer level as an early indicator in acute mesenteric ischemia in rats.Methods:Forty-eight mature male Wistar rats were divided equally into experimental group (EG) and control group (CG),The superior mesenteric artery was ligated In EG,and while a simple laparotomy was performed in CG.Blood samples were taken for laboratory test in both groups at 1h、6h、12h respectively.Results:The longer the duration of mesenteric ischemia,the higher were the serum D-dimer levels in the study groups,and statistical significance was obtained between these two groups (P=0.0375).Otherwise,significant difference was not found in other laboratory parameters between them.Conclusions:Serum D-dimer dynamic measurements may be a important valuable screening parameter in the early diagnosis of mesenteric ischemia.更多还原
