Objective To explore the causes of fetal distress through B-ultrasound to determine the physiological and pathological status and prognosis of the fetus. Methods By observing fetal heart rate, umbilical cord, amniotic fluid, fetal movement, to make a diagnosis. Results Fetal heart rate, fetal motion abnormalities is to determine whether the fetus with or without hypoxia and its major indicators; umbilical cord, amniotic fluid is the main cause of fetal distress. B-ultrasound diagnosis and postpartum coincidence rate 100%. Conclusion Ultrasound diagnosis is fast, accurate, simple, economical and noninvasive. It provides a powerful basis for the observation of labor and the choice of mode of delivery, which is of great significance in preventing and reducing perinatal mortality.
