The Clinical, Subclinical Characteristics and the Factor Associated of Intrauterine Fetal Death at ≥14 Weeks of Pregnancy

The study carried out on 84 women with intrauterine fetal death at ≥14 weeks of pregnancy hospitalized at obstetrics and gynecology department in Tay Nguyen Regional General Hospital from 1/2024 to 12/2024. The average age of pregnant women is 30,5 ± 8,3 years old, 60,7% of cases were multiparous pregnancy. The average age of stillbirth was 28,7 ± 9,2 weeks. 40,5% of pregnant women detect stillbirth because of abdominal pain or vaginal bleeding, 38,1% because the fetus was not moving, and 21,4% discovered the stillbirth during a periodic prenatal examination. 59,5% had regular check-ups during pregnancy. 14% case of them detected abnormalities. In the second trimeste, abnormalities detected during prenatal check-ups are usually related to fetal malformations, while in the third trimester, most abnormalities are associated with the placenta, umbilical cord, and amniotic fluid (p<0,05), 2 groups of maternal disease in study are high blood pressure in pregnancy and metabolic disorders. Most participants were multiparous women from rural areas with low educational levels, admitted due to abdominal pain, vaginal bleeding, or absent fetal movement. Despite over half receiving adequate antenatal care, a notable rate of abnormalities was detected—fetal anomalies mainly in the second trimester, and placental, umbilical cord, or amniotic fluid issues in the third (p<0.05). The most common maternal conditions were gestational hypertension and metabolic disorders. These findings highlight the importance of comprehensive prenatal monitoring, especially in high-risk groups.
