Under normal circumstances, the number of fetal movements per hour is 3-5 times. There are more reasons for frequent fetal movement in 35 weeks of pregnancy, it may be physiological, such as after the pregnant woman bath, after eating the fetal blood supply is sufficient, may be frequent fetal movement, in this case the pregnant woman is generally not accompanied by uncomfortable symptoms, it is recommended that appropriate rest, can be temporarily observed. If the frequent fetal movements do not improve, accompanied by other symptoms, may be pathological causes, need to promptly seek medical treatment, common pathological causes include the following aspects: 1, fetal acute intrauterine distress: common cause is the umbilical cord factors, there may be an umbilical cord around the neck or umbilical cord around the body. After the umbilical cord is pressurized, the fetal blood oxygen supply is affected, which will cause frequent fetal movements, and it is recommended to go to the hospital for examination in time. First of all, you need to do fetal 3D ultrasound to observe the situation of the fetus in the uterus, and also need to do fetal heart monitoring to notice whether the fetus has intrauterine hypoxia. The left lateral position can be adopted to reduce the pressure on the inferior vena cava and relieve the intrauterine distress of the fetus. If the fetal movement is still frequent after taking the left-sided position, it is recommended to properly administer oxygen and observe whether the fetal movement is relieved; 2, pregnant women have pregnancy complications: if gestational hypertension occurs in the 35th week of pregnancy, accompanied by frequent fetal movement, suggesting that the condition is more serious, it is recommended to promptly seek medical treatment to lower the pressure and preserve the fetus; 3, pregnant women have fever: if the body temperature of pregnant women is significantly higher in the 35th week of pregnancy, the heart rate of the fetus will also become faster, causing frequent fetal movement. This will cause frequent fetal movements. Need to promptly consult a doctor, do routine blood and blood culture examination, if it is clear that the bacterial infection, if necessary, the use of sensitive antibiotics for treatment.
