Intrauterine hypoxia may be manifested by decreased or disappeared fetal movement, and changes in fetal heart rate and cloudy amniotic fluid may also be found after going to the hospital for relevant examinations. 1. Decrease or disappearance of fetal movement: intrauterine hypoxia is usually manifested by decrease or disappearance of fetal movement, for fetus after 34 weeks of gestation, their sympathetic and parasympathetic development is basically sound, the fetus will have its own waking and sleeping cycle, every day’s activities are regular, if the fetal movement is decreased or disappeared, it suggests that the fetus may be suffering from hypoxia. 2. Fetal heart rate change: normal fetal heart rate should be uniform and regular, intrauterine hypoxia may cause fetal heart rate to become faster and then slower. 3. Clouding of amniotic fluid: intrauterine oxygen deprivation will cause vagus nerve excitation, which will increase intestinal peristalsis and relax the anal sphincter, resulting in a small amount of meconium being discharged into the amniotic fluid, which is why amniotic fluid will become cloudy during the ultrasound examination. There are many signs of intrauterine hypoxia, if there are obvious abnormalities, pregnant women need to go to the hospital in time to complete the relevant examinations, with the doctor for standardized treatment.
