Application progress of gastric mucosa pH monitoring technique after congenital heart disease operation / 中华实用儿科临床杂志

ABSTRACT

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 intramucosal pHi monitoring technology in the application of congenital heart disease was reviewed.
