Fetal movement in 38 weeks of pregnancy is strong and powerful, usually caused by physiological factors, but also may be an abnormal situation, need to borrow the relevant examination methods for differential diagnosis. First, the common causes and treatments: 1, emotional, dietary influences: if the increase in fetal movement occurs after the pregnant woman has eaten too cold or spicy stimulating food, it may be caused by improper diet to stimulate uterine contraction. In addition, pregnant women’s excessive emotional tension or excitement can also cause a significant increase in fetal movement. Generally speaking, after improving dietary habits, adequate rest, relaxation, frequent fetal movement will gradually return to normal; 2, intrauterine fetal hypoxia: if the number of fetal movements suddenly frequent, or no intermittent restlessness, may be the initial manifestation of intrauterine hypoxia, may be the umbilical cord around the neck tighter, placental dysfunction and other factors. At this time, you should go to the hospital in time to complete the ultrasound examination and conduct fetal heartbeat monitoring. If the mouth of the uterus is not open and the fetus is developing well, you can continue to inhale oxygen to increase the blood oxygen content of the mother’s body, improve the environment for fetal growth and development, and alleviate the symptoms of hypoxia; if the mouth of the uterus is open or the fetus appears to be in intrauterine distress, you should deliver the baby as soon as possible to avoid fetal death in the uterus. Second, precautions: normal pregnancy from the 34th week of pregnancy to do a weekly fetal heartbeat monitoring, pregnant women in the morning, midday, evening relatively fixed time every day to measure the fetal movement for 1 hour, the fetal movement count 3-5 times per hour, 12 hours is generally 30 times. Fetal movement beyond the normal range is frequent, should pay attention to close observation.
