Abstract

Background: Abnormal fetal middle cerebral artery (MCA) doppler untrasound is associated with hypoxia of fetus. The identification of characteristics and fetal outcomes of pregnant women with abnormal fetal MCA Doppler ultrasound is essential for timely intervention to achieve maternal and neonatal safety. Objectives: To calculate the rate and describe clinical features, laboratory findings, related factors and the fetal outcomes of pregnant women in labor with abnormal fetal MCA Doppler ultrasound at Cantho Gynecology Obstetrics hospital. Materials and methods: a descriptive cross-sectional study of 1481 pregnant women in labor with gestational age ≥ 37 weeks at Cantho Gynecology Obstetrics hospital between October 2016 and April 2018. Results: The rate of women with abnormal MCA Doppler ultrasound is 19.2%. The rates of primigravida was 55.4%; uterine tachysystol 2.1%; 15.4% with rupture of membranes; meconium staining of amniotic fluid 13.7%, abnormal CTG 17.9%, abnormal cerebroplacental ratio 2.5%. Caesarean section was conducted on 60.7% patients, low birth weight 6.7%, The rate of Apgar score values upper than 7 at 1st min was 92.6% and 1.2% of newborn was death. We found the statistically significant association between abnormal fetal MCA Doppler ultrasound and uterine tachysystole, oligoamnios, low birth weight. Conclusions: When the hypoxic fetus during labor can be manifested through RI (Resistive Index), PI (Pulsatility Index) of fetal MCA Doppler, it is necessary to perform Doppler ultrasound to evaluate the change and when abnormal fetal MCA Doppler ultrasound we should use cerebroplacental ratio to limit excessive interference.
