Normally, fetal movement should be not less than 3-5 times an hour. However, depending on the growth and development of the fetus, the amount of amniotic fluid in the uterus, the size of the pregnant woman and other factors, the specific number of fetal movements varies from person to person. Most of the pregnant women in 18-20 weeks of pregnancy can feel the fetal movement, and then the number of times gradually increase, the amount of activity is also more and more, in 32-34 weeks is the most active, but to the end of pregnancy, that is, 38 weeks after the gradual decrease. Fetal movement count in 12 hours is commonly used in clinical practice, the specific method is to count 1 hour of fetal movement in the morning, midday and evening, and multiply the number of fetal movements in the three time periods by 4, that is, the number of fetal movements in 12 hours, and the number of fetal movements counted > 30 times/12 hours is normal. Fetal movements should be counted as one continuous movement of the fetus, and should not be counted as multiple movements of the fetus. Pregnant women should cooperate with their doctors to have regular checkups during pregnancy and count the fetal movements themselves, and in the middle and late stages of pregnancy, i.e. after 28 weeks, they should count the fetal movements themselves regularly. If the number of fetal movements is less than 20 in 12 hours, it should be taken seriously and the fetal heart rate should be closely monitored. If the number of fetal movements is less than 10 in 12 hours, intrauterine distress may occur due to fetal hypoxia. Therefore, the number and strength of fetal movements can directly reflect the safety of the fetus. If the fetal movement decreases or the fetal movement is intense, you should be vigilant and go to the hospital in time. You can increase the blood oxygen level in the pregnant woman’s body through oxygen inhalation, change the body position, etc., so as to improve the situation of fetal hypoxia.
