1.Counting fetal movements Count fetal movements after 28 weeks of pregnancy, if the fetal movements are normal, it means the fetus is safe in the womb. Please refer to my other article “What kind of fetal movement is normal”. 2.Fetal ultrasound During the whole pregnancy, if everything goes well, a total of 6 ultrasounds will be done (i.e. the first one at about 7 weeks of pregnancy; the second one for NT, the third one at 16 to 18 weeks of pregnancy, the fourth one at 20 to 24 weeks of pregnancy, the fifth one at 30 to 32 weeks of pregnancy and the sixth one at 38 weeks of pregnancy). Please refer to the article “Procedure of maternity checkup”. All ultrasound results are normal, including fetal growth and development, amniotic fluid volume, S/D ratio of umbilical blood flow, and exclusion of placenta praevia or placental implantation. 3.Fetal monitoring Generally speaking, the fetal monitoring starts at 34 to 35 weeks of pregnancy, once a week, if the fetal monitoring score is good, it means that the baby is not hypoxic in the uterus. On the contrary, if the fetal monitoring response is not good, you can recheck it after eating or taking oxygen, if it is better, it is fine, if not, you need to be admitted to hospital for observation. The sensitivity of fetal monitoring is too high, because hunger and fetal sleep can cause poor fetal monitoring response, so you should eat well and exercise before doing fetal monitoring to feel the fetal activity, so as not to cause errors. In addition to the weekly fetal monitoring, if the fetal movement is frequent or reduced, you also need to come to the hospital to do fetal monitoring to see if the fetus is really hypoxic. 4, control blood sugar In case of gestational diabetes or gestational diabetes with poor blood sugar control, the fetus may have unpredictable fetal death in the womb. Therefore, it is important to check fasting blood sugar and glycosylated hemoglobin in early pregnancy to see if there is diabetes before pregnancy, and if there is, it is called “gestational combined diabetes”. A glucose tolerance test is done at 24-28 weeks of regular labor and delivery, and if any of these tests are exceeded, the diagnosis of “gestational diabetes” is made. The standard is that fasting blood sugar should not exceed 5.3, one hour after meal blood sugar should not exceed 7.8, and two hours after meal blood sugar should not exceed 6.7. If the control is not good, you should be hospitalized for monitoring to avoid the bad outcome of fetal death in the womb. 5. Prevention and control of cholestasis of pregnancy syndrome In late pregnancy, there is another condition: when itchy skin, especially itchy fingers and toes, no rash, yellow skin and sclera, and elevated bile acid and sometimes elevated transaminase, it can be diagnosed as “cholestasis of pregnancy syndrome”, and this condition is also prone to In this case, there is also a risk of unpredictable intrauterine death. Once the diagnosis of cholestasis of pregnancy is made, hospitalization is required, with close monitoring of fetal movements and twice-daily fetal monitoring, as well as bile acid lowering therapy.
