摘　　要：先天性心脏病（先心病）作为最常见的一种先天性解剖畸形，主要治疗方式为体外循环下行手术矫治。手术后部分患儿会出现低心排出量综合征（低心排），使得机体血流重新分布，心脏及脑部是首先要保证血流灌注的器官，因此胃肠道组织不能得到充分的灌注，使得胃肠道缺氧缺血，酸性代谢产物堆积。胃黏膜pH值（pHi）能敏感地反映胃黏膜缺氧缺血状态，对低心排有一定的预警作用。目前测定pHi的方法有盐水张力计法和连续空气张力计法。现就pHi监测技术在先心病术后的应用做一综述。Congenital heart disease （CHD） as the most common type of congenital anatomical deformity, the main treatment is surgical correction undergoing cardiopulmonary bypass. Some children will appear low cardiac output syndrome after the operation, it makes the body blood flow redistribution. The heart and brain are the organs which are ensured the blood perfusion at first. The gastrointestinal tract can not be fully perfused because of that, which makes gastrointestinal tract ischemia and hypoxia, acid metabolites accumulation. Gastric intramucosal pH （ pHi ） can reflect the gastric mucosal hypoxia status sensitively, warn the low cardiac output syndrome. At present, the pHi determines method includes the salt water tensiometer law and the continual gaseous state tensiometer law. Now, the gastric intramueosal pHi monitoring technology in the application of congenital heart disease was reviewed.
