| Abstract | Objectives: Cervical effacement and dilatation, station of the presenting part, and fetal head positionare the key determinants of progress of labor. There is growing evidence about the usefulnessof intrapartum ultrasound in evaluating the labor parameters objectively to decide about thelabor management. Hence, intrapartum translabial ultrasound was studied to predict the modeof delivery.Materials and Methods: 185 laboring women with singleton pregnancy, term gestation, and cephalicpresentation with 4 cm. cervical dilatation were included. Intrapartum translabial ultrasound wasdone to note angle of progression (AoP), cervical length, and position of the fetal head.Results: Among 185 women, 121 (65.4%) had vaginal (112 normal and 9 assisted vaginal) and 64cesarean (34.6%) delivery. An angle of progression of 89o with area under the curve (AUC)0.789 (p ? 0.0001) measured in the early active phase of labor had a sensitivity, specificity,positive predictive value and negative predictive value of 79.3% and 65.6%, 81.3% and 62.7%respectively. The positive likelihood ratio and the negative likelihood ratio were 2.3 and 0.315,respectively. The clinical utility index for AoP was 0.644 in predicting the mode of delivery. AUCfor cervical length was 0.534 (p = 0.452), which was not significant. The odds ratio foroccipitoanterior position in predicting vaginal delivery was 3.9.Conclusion: Intrapartum translabial ultrasound is a reproducible and feasible method to evaluatelabor parameters. Assessing multiple components like the angle of progression, cervical length,and position of the fetal head in early labor could help to predict the mode of delivery. |
