Intrapartum sonographic assessment of fetal head position and descent of fetal head in prediction of labor outcome

Abstract

To predict the progress and outcome of labor by assessing fetal head position and descent of fetal head by intrapartum ultrasound. Study design: Prospective observational study. Method: Ninety two primigravida with singleton term gestation in active labor with vertex presentation and intact membrane were recruited in the study. Intrapartum ultrasonographic evaluation was done to assess fetal head position and descent of fetal head. Result: Women with occipito anterior fetal head position and angle of progression (AOP) >120 degree were more likely to have successful vaginal delivery. It was also found that larger the AOP, lesser was the mean time to delivery interval. Conclusion: Intrapartum ultrasonographic assessment of fetal head position and descent of fetal head is a predictor of mode of delivery and labor out-come.
