P20.07: Doppler study in intrauterine growth restricted fetuses

Abstract

and abnormal S/D ratio group(n = 11). All cases were delivered at 37 + 0-41 + 6 weeks of gestational age from January 2001 to December 2008 at Ajou University Medical Center. The criteria for S/D ratio of umbilical artery was 3.0 and the neonatal weight < 10percentile compared to gestational age was used for definition of IUGR. Gas analysis and blood tests, including nRBC count in umbilical artery, were done during delivery. Results: The abnormal S/D ratio group showed significantly higher numbers of nRBC compared to the other groups (2.25 vs 4.67 vs 8.91/WBC100, p < 0.05). Also there was a significant decrease of neonatal weight in the abnormal S/D ratio group compared to the other groups (2130gm vs 2420gm vs 3211gm, p < 0.005). Conclusions: The number of nRBC of the umbilical artery showed an increase in the group of abnormal S/D ratio and associated with decreased neonatal weight.
