The examinations that need to be performed during the 37-week maternity checkup generally include routine examination, fetal heart monitoring, ultrasound examination and cervical examination, according to which the physical status of the pregnant woman and the development of the fetus are judged comprehensively: 1. The purpose is to monitor whether the pregnant woman has gestational hypertension, gestational diabetes, etc., and to make preliminary observations on the development of the fetus; 2. fetal heart monitoring: the main purpose is to assess whether the fetus is hypoxic in the uterus, so as to correct it in time and improve the survival rate of the newborn; 3. ultrasound examination: the fetus at 37 weeks of pregnancy is full term and more mature in all aspects. Therefore, the fetal size, fetal position, intrauterine amniotic fluid content and placental maturity can be assessed through ultrasound examination to further understand the development of the fetus; 4. It is recommended that pregnant women can communicate with their doctors about the mode of delivery and make rational judgments based on the results of various examinations, so as to make adequate preparations in advance.
