孕妈妈越临近预产期,就越担心可怕的难产会发生在自己身上。其实只要在设备完善的医疗院所进行妥善的产前检查与及时处理,难产并不是那么可怕。孕妈妈自己不必放大“假想难产”的程度。难产的四种因素1.不正常胎位或胎向不正常。因为产前超音波的广泛使用,不正常胎位(臀位或横位)大都会被发现,胎向不正常(如胎儿的后脑勺在正后方)一般需要在待产过程中依靠内诊来发现。2.胎儿过大。胎儿过大跟骨盆腔狭窄其实是相对的,骨盆腔比较宽的妈妈就可以顺产生下比较大的婴儿。在一些比较特殊的情况下,容易有胎儿过大的情形发生,如患有糖尿病或妊娠糖尿病的妈妈、前一胎是巨婴等等。
Pregnant mothers closer to the expected date of delivery, the more worried about the dystocia will occur in their own body. In fact, as long as well-equipped medical institutions for proper prenatal care and timely treatment, dystocia is not so terrible. Pregnant mothers do not have to enlarge their own “imaginary difficult delivery” level. Four factors of dystocia 1. Abnormal fetal position or fetal abnormalities. Because of the widespread use of prenatal ultrasound, abnormal fetal bones (breech or transverse) are mostly found, abnormal fetal orientation (such as the fetal head in the back of the rear) generally need to rely on in the process of waiting to find out. The fetus is too large. Fetal pelvic pelvic stenosis is actually relatively large, pelvic relatively wide mother can produce a relatively large baby. In some special circumstances, prone to excessive fetal situation, such as diabetes or gestational diabetes, mother, the previous baby is a giant baby and so on.
