脐带是胎儿的生命线。如果脐带发生异常情况,无论在孕期或分娩过程中,常可使胎儿突然发生宫内窘迫、胎死宫内、出生后窒息或死亡,个别情况(脐带过短)还可能累及产妇。所以对脐带异常情况,应该引起产科工作者的高度重视。现将临床上常见的一些异常情况,略述如下: 脐带扭曲:脐带在发育过程中,三根脐血管的长度远远超过脐带的长度,因而形成螺旋状的扭曲,一般足月胎儿的脐带大约有20个左右的扭曲。从生理学角度看,这是自然界的一个巧妙安排,有了这些扭曲,不但增加了脐带的坚韧性,而且当一部分脐带弯
Umbilical cord is the lifeline of the fetus. If the umbilical cord anomalies, either during pregnancy or childbirth, often make sudden fetal distress intrauterine fetal distress, fetal death, suffocation or death after birth, in some cases (the umbilical cord is too short) may also affect the mothers. Therefore, the abnormal situation of the umbilical cord, should cause obstetric workers to attach great importance. Now common clinical abnormalities, outlined as follows: Umbilical cord distortion: the umbilical cord during development, the length of the three umbilical vessels far beyond the length of the umbilical cord, and thus the formation of spiral twisting, umbilical cord generally full-term fetus about Twenty or so distortions. From a physiological point of view, this is an ingenious arrangement in nature, with these distortions, not only increased the tenacity of the umbilical cord, and when part of the umbilical cord bend
