Résumé
Knowing the factors affecting fetal distress is of particular importance in improving prognosis in newborns. The study aimed to determine the relationship between fetal middle cerebral artery pulsatility indexes and umbilical artery Doppler ratio with fetal distress at 38-40 weeks of gestation. In this prospective cohort, 181 consecutive pregnant women with 38-40 weeks of gestational age were selected by a non-random convenience sampling method from January 2016 to January 2017. Women with labor pain and embryos with chromosomal and structural disorder were excluded. Color Doppler sonography was done for all of them, and the association of this ratio with fetal distress consequently was assessed as well. In this study, abnormal amniotic fluid index (AFI) (1.1%), low birth weight (< 2500 g) (5.5%), emergency cesarean (11.6%), neonatal intensive care unit (NICU) admission (12.2%), low 5th minute Apgar (< 7) (0.6%), abnormal fetal monitoring (10.5%), fetal distress (11.6%), meconium aspiration syndrome (10.5%), and respiratory distress (3.9%) were present. The mean cerebroplacental ratio was 1.9. There was a significant association between low fetal middle cerebral artery pulsatility index and umbilical artery Doppler ratio with fetal distress, abnormal monitoring, and urgent cesarean ( It may be concluded that in our study a cutoff for fetal middle cerebral artery to umbilical artery ratio of 1.94 at 38 weeks was considered statistically significant in predicting fetal distress at 38-40 weeks. However, further studies with larger sample size and multi-center sampling would develop more definite results for wider application.

BACKGROUND AND OBJECTIVE
OBJECTIVE
Knowing the factors affecting fetal distress is of particular importance in improving prognosis in newborns. The study aimed to determine the relationship between fetal middle cerebral artery pulsatility indexes and umbilical artery Doppler ratio with fetal distress at 38-40 weeks of gestation.
MATERIALS AND METHODS
METHODS
In this prospective cohort, 181 consecutive pregnant women with 38-40 weeks of gestational age were selected by a non-random convenience sampling method from January 2016 to January 2017. Women with labor pain and embryos with chromosomal and structural disorder were excluded. Color Doppler sonography was done for all of them, and the association of this ratio with fetal distress consequently was assessed as well.
RESULTS
RESULTS
In this study, abnormal amniotic fluid index (AFI) (1.1%), low birth weight (< 2500 g) (5.5%), emergency cesarean (11.6%), neonatal intensive care unit (NICU) admission (12.2%), low 5th minute Apgar (< 7) (0.6%), abnormal fetal monitoring (10.5%), fetal distress (11.6%), meconium aspiration syndrome (10.5%), and respiratory distress (3.9%) were present. The mean cerebroplacental ratio was 1.9. There was a significant association between low fetal middle cerebral artery pulsatility index and umbilical artery Doppler ratio with fetal distress, abnormal monitoring, and urgent cesarean (
CONCLUSION
CONCLUSIONS
It may be concluded that in our study a cutoff for fetal middle cerebral artery to umbilical artery ratio of 1.94 at 38 weeks was considered statistically significant in predicting fetal distress at 38-40 weeks. However, further studies with larger sample size and multi-center sampling would develop more definite results for wider application.
