The decrease of fetal movement at 32 weeks of pregnancy can be roughly divided into three reasons: fetal intrauterine hypoxia, intrauterine amniotic fluid reduction and fetal occurrence of cord winding, which need to go to the hospital for examination in time: 1. There are more factors that cause fetal intrauterine hypoxia, such as lower maternal blood oxygen content and low placental function. At this time, pregnant women need to go to the hospital further for fetal heart monitoring and abdominal ultrasound, and carry out appropriate treatment according to different reasons, for example, if the fetal heart is good, pregnant women can be given oxygen therapy and bed rest. If the hypoxia is corrected and the fetal movement is significantly better, the pregnancy can be continued; if the fetal movement is still reduced and the fetal heartbeat appears abnormal, the pregnancy needs to be terminated in time. 2. Intrauterine amniotic fluid reduction Amniotic membrane rupture, placental abnormality, and the pregnant woman’s own poor physical condition can cause intrauterine amniotic fluid reduction, and it is recommended to terminate the pregnancy at this time. If the amniotic fluid is reduced and fetal distress is combined, a cesarean section should be taken in time; if the fetal reserve function is still good, a vaginal trial of labor can be attempted and real-time attention should be paid to the fetal heart changes. 3, the fetus has an umbilical cord around the neck umbilical cord around the neck leads to fetal distress and restricts fetal movement. For example, if the umbilical cord is too tight and the fetal blood circulation is obstructed, the pregnancy should be terminated in time.
