摘　　要：感染、创伤、休克等应激状态后,胃肠是最容易受损的器官。胃肠功能衰竭发生率高,严重影响危重患儿预后,但缺乏适用于临床的明确诊断指标。肠系膜上动脉是肠道主要供血来源,监测它的血流灌注能反映肠道功能。近年来应用近红外光谱技术(near infrared spectroscopy,NIRS)监测腹部血氧饱和度(rSO2),可反映肠道的血流灌注,间接反映肠道功能。本文基于国内外对胃肠功能衰竭的最新进展,整理了NIRS在胃肠方面的广泛应用,提出对胃肠功能衰竭诊断的适用于临床的有力指标——肠系膜局部组织血氧饱和度。The gastrointestinal tract is the most vulnerable organ to infection,trauma,shock and other stress states.The incidence of gastrointestinal failure is high,which seriously affects the prognosis of critically ill children,but it lacks clear diagnostic indicators for clinical application.The intestinal blood supply mainly comes from superior mesenteric artery,so the blood perfusion of superior mesenteric artery can reflect the intestinal circulation.Based on the latest progress of gastrointestinal failure all over the world,and the extensive application of near infrared spectroscopy in brain and gastrointestinal tract,this study puts forward a powerful clinical index for the diagnosis of gastrointestinal failure-mesenteric local tissue oxygen saturation.
