胎儿水肿是指胎儿组织内浆液过度积聚。除了皮下组织水肿外,也可以出现腹腔积液、胸腔积液甚至心包积液。胎儿水肿的严重度可按照发生渗出的体腔的数目分级。四级法为0、1、2和3级。分别代表无体腔渗出和1、2或3个体腔渗出。胎儿水肿包括免疫性和非免疫性两大类。免疫性胎儿水肿以Rh血型不合的新生儿溶血病为代表。有关免疫性胎儿水肿内容的综述很多,这儿不再讨论。本文重点综述一下非免疫性胎儿水肿。在1970年,西方国家估计有大约20%的水肿胎儿是非免疫性的。而且,随着Rh免 Fetal edema refers to excessive accumulation of fluid within the fetal tissue. In addition to subcutaneous edema, but also can occur ascites, pleural effusion and pericardial effusion. The severity of fetal edema can be graded according to the number of body cavities where exudation occurs. Level 4 law is 0,1,2 and 3 levels. Respectively, no body cavity exudation and 1, 2 or 3 body cavity exudation. Fetal edema, including immune and non-immune two categories. Immune fetal edema to Rh blood group incompatible neonatal hemolytic disease as the representative. There are a lot of reviews on the content of immune fetal edema and we will not discuss it here. This article focuses on non-immune fetal edema. In 1970, Western countries estimated that about 20% of edematous fetuses are non-immune. And, with Rh free
