做好孕期检查是很重要的。在检查中常可发现母体和胎儿的异常情况,及时地加以纠正和治疗。但是,有些异常情况在孕期检查中未能查出,直到分娩进行到某一阶段才被发现。所以在分娩过程中,必须随时注意胎儿有无异常情况的发生。 Good pregnancy check is very important. In the inspection can often find maternal and fetal abnormalities, in a timely manner to be corrected and treated. However, some abnormalities were not detected during the pregnancy test and were not found until some stage of delivery. Therefore, in the delivery process, we must always pay attention to the fetus with or without anomalies.
