To explore the effect of implementing fetal systemic ultrasound screening in Material and Child Health Hospital of Shannan.

The data of pregnant women at 11-40 gestational weeks who received prenatal ultrasound examination during 2016—2021 at Material and Child Health Hospital of Shannan were retrospectively analyzed. The change in the number of pregnant women receiving prenatal ultrasound screening, the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester, the ratio of the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester to that of pregnant women receiving prenatal ultrasound screening, the number of fetal abnormalities detected by prenatal ultrasound, the detection rate of fetal abnormalities by prenatal ultrasound, the gestation weeks when fetal abnormalities were detected, and the ranking and distribution of fetal abnormalities after implementing the fetal systemic ultrasound screening were then analyzed.

After implementing the fetal systemic ultrasound screening, the number of pregnant women receiving prenatal ultrasound screening, the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester, the ratio of the number of pregnant women receiving fetal systemic ultrasound screening in the mid-trimester to that of pregnant women receiving prenatal ultrasound screening, and the number and detection rate of fetal abnormalities detected by prenatal ultrasound all increased. The detection rate of fetal abnormalities by prenatal ultrasound increased to 1.03% from 0.39%. The number of fetal abnormalities detected by prenatal ultrasound in the first trimester (11-13⁺⁶ weeks) and the early mid-trimester (14-17⁺⁶ weeks) increased from zero to 12, and showed an increasing trend year by year; and appendage abnormalities still ranked first. The type of fetal abnormalities increased from 6 to 34. Single umbilical artery (SUA) and aberrant right subclavicular artery (ARSA) accounted for 40.16% of all fetal abnormalities detected by prenatal ultrasound.

Implementing the standardized fetal systemic ultrasound screening could make more pregnant women to receive the prenatal ultrasound screening, improve the detection rate of fetal abnormalities, and reduce the incidence of fetal abnormalities.
