The maternity checkup at 29 weeks of pregnancy includes general checkup and obstetrical checkup. The whole body examination includes blood pressure, pulse, weight, etc.; the obstetric examination includes uterine height, abdominal circumference, fetal heartbeat, fetal position, etc. In addition, 3D ultrasound examination of the fetus is needed, as well as related auxiliary examinations. I. Systemic examination includes blood pressure, pulse rate, weight and so on. The blood pressure of pregnant women should be <140/90mmHg. Usually, at 29 weeks, it is found that the blood pressure is significantly elevated, >140/90mmHg, and it is considered that it may be hypertensive disease in pregnancy, and it is recommended that pregnant women should be hospitalized for treatment in time. At 29 weeks of pregnancy, a 75g glucose tolerance test is required. The blood glucose values of 1h and 2h after fasting and sugar should be lower than 5.1mmol/L, 10.0mmol/L and 8.5mmol/L respectively, and any point where the blood glucose value reaches or exceeds the above standard is diagnosed as gestational diabetes. Second, obstetric examination includes uterine height, abdominal circumference, fetal heartbeat, fetal position, etc. Attention should be paid to observe whether the size of the fetus is in line with 29 weeks. It is necessary to measure the biparietal diameter, femur length, head circumference, chest circumference, amniotic fluid depth, amniotic fluid index, to see the position of the placenta, the thickness of the placenta, and to pay attention to whether the umbilical cord is wrapped around the neck, and to check whether the fetus has any malformations, such as facial part, limbs, brain, internal organs, heart malformations, etc. At 29 weeks of labor and delivery, 3D ultrasound examination is required. If the fetus is found to be less than 29 weeks old, it is also necessary to measure the umbilical artery blood flow and middle cerebral artery blood flow during the ultrasound to note whether the fetus has intrauterine hypoxia. In addition, if an abnormality is found in the fetus during the ultrasound, cord blood puncture and chromosomal examination should be done to note whether there is any chromosomal or genetic abnormality. Usually, MRI is needed when fetus is found to have widened lateral ventricles and increased fluid in the posterior cranial fossa at 29 weeks. It is recommended that pregnant women should pay close attention to monitor fetal movement, normal fetal movement is 3-5 times per hour, and it is recommended to count fetal movement 3 times per day. Auxiliary examination is needed to measure the blood routine, urine routine and electrocardiogram of pregnant women in 29 weeks of pregnancy. The routine blood test is mainly to check whether the pregnant woman has anemia, and iron deficiency anemia is easy to appear after pregnancy, which will be reflected in the routine blood test. The urine routine needs to take the middle urine, mainly to check whether there are parasites and fungal infections, and also to check whether there is urine protein to determine the kidney function. The electrocardiogram is to check whether the pregnant woman has insufficient blood supply to the heart.
