Since the two-child policy has been fully liberalized, the number of elderly women has increased, and the widespread application of assisted reproductive technology has increased the proportion of high-risk pregnancy year by year, which adds new challenges to obstetric work. High-risk pregnancy not only increases the risk of pregnancy complications, but also threatens the health of mother and child. Prenatal screening and pregnancy care for high-risk pregnant women are essential to ensure their safety through pregnancy and delivery. In recent years, with the continuous improvement of prenatal screening and hierarchical medical system, high-risk pregnant women have received more intensive monitoring and active intervention. At the same time, the promotion of Internet + hospitals has also achieved initial results in the field of obstetrics, which has increased the convenience of perinatal health care services. However, there are still differences in maternal health status between urban and rural areas and among different regions, and the supply capacity of maternal and child health services needs to be improved. In terms of reducing maternal and perinatal mortality, obstetric workers and maternal women still need to work together to improve the management of high-risk pregnancies, prevent adverse pregnancy outcomes, and ensure the safety of mothers and infants.
