Late pregnancy requires obstetric ultrasound, fetal heart monitoring, blood pressure, weight measurement, auscultation of the fetal heart, liver function tests, and screening for group B streptococcus. After entering the late stage of pregnancy, women need to go to the hospital for a number of examinations, mainly including the following aspects: 1. Obstetric ultrasound examination. Obstetric ultrasonography is done to determine the position of the fetus as well as its development, observe the function of the placenta, look at the amount of amniotic fluid, and see if there are any abnormalities such as umbilical cord around the neck. 2. Fetal heart monitoring. Generally, after 34 weeks of pregnancy, you need to go to the hospital regularly for fetal heart monitoring, which can observe the changes of the fetal heart and determine whether the fetus has hypoxia. After 37 weeks of pregnancy, you should go to the hospital every week for fetal heart monitoring. 3. Measure blood pressure and weight. In late pregnancy, you should pay attention to the measurement of blood pressure to prevent the emergence of gestational hypertension. Pay attention to the change of weight, if the weight gain is too fast in a short period of time, consider whether there is edema. 4. Listen to the fetal heart. Women should pay attention to listening to the fetal heart in the late stage of pregnancy, and determine whether the fetus has hypoxia by observing the changes of the fetal heart. 5. Liver function test. In the 32-34 weeks of pregnancy, if there is a suspicion of intrahepatic cholestasis in pregnancy, it is usually necessary to draw blood to check liver function and serum bile acids. 6. Group B streptococcus screening. At 35-37 weeks of pregnancy, screening for group B streptococcus is needed to determine whether there is a group B streptococcus infection, so as not to affect the labor.
