由于胎盘功能复杂,因此它的功能不能被任何一项胎盘功能指标所决定,而且胎儿和胎盘由同一胎卵产生,所以胎儿功能和胎盘功能很难区分。现将迄今关于胎儿胎盘功能检查法汇集如表一,但临床上常是根据不同的情况,选择其中几项检查方法,以求了解胎盘功能和胎儿功能。 Due to the complex function of the placenta, its function can not be determined by any one of the indicators of placental function, and the fetus and placenta are produced by the same fetus, so the function of the fetus and placenta are difficult to distinguish. So far on the fetal placental function test method pooled in Table 1, but the clinical is often based on different situations, choose one of several test methods in order to understand the placental function and fetal function.
