“…In the study by Dupuis et al performed on a phantom, residents made mistakes in 50-88% of cases and obstetricians in 36-80% (depending on the position of the head of the fetus) in determining the head station in birth canal measured with the numerical system [6].…”

Objectives: The aim of the study is to determine the usefulness of ultrasound parameters in the second stage of labor in prediction of the method of delivery and to evaluate the benefits to be derived from this study. Material and methods:Ultrasound scan was performed with Convex transabdominal probe on 68 pregnant women in labor at term with fetuses in cephalic presentation at the beginning of the second stage of labor and parameters such as angle of progression, head progression distance, head-symphysis distance and head-perineum distance were measured. The parameters were observed in two scans: a midline scan visualizing the pubic symphysis with the head of the fetus and a transverse scan approximately 1-2 cm below the pubic symphysis visualizing the head of the fetus. Results:The ultrasound parameters measured at the beginning of the second stage of labor, differed in the group in which women have delivered vaginally and in the group, in which caesarean section was performed: angle of progression and head progression distance were greater in group of women who delivered naturally and head-perineum distance and head-symphysis distance were smaller in this group. Some relations between each measured parameter and time left to delivery were observed as well as strong relations among parameters were also observed. Conclusions:Intrapartum sonography is a useful and objective tool to assess the progress of labor. Transperineal ultrasound scans performed in the second stage of labor may play a role in making the decision about the mode of delivery.

“…2 Akmal et al reported that digital VE failed to determine the fetal head position in 34% of laboring women, and incorrectly determined head position in 51% of patients in whom the position could be defined. 3,4 Digital VE are shown to be associated with infection ascending to the fetus, chorioamnionitis, endometritis and shortened time interval to delivery in preterm labor.…”

Background: Non-invasive transperineal ultrasound has been used to detect the descent of the fetal head using head-perineum distance (HPD) and angle of progression (AOP). The aim was to evaluate HPD and AOP as predictors of vaginal delivery in the first stage of labor.Methods: This was a prospective cohort study in Riga Maternity Hospital in Latvia from May till August 2016. The study included only nulliparous women with singleton pregnancies and cephalic presentation. Ultrasound was used to measure HPD and AOP. Data was collected on demographics, labor parameters and outcome.Results: Of 36 women enrolled, 26 (72.2%) had a vaginal delivery. The area under the receiver–operating characteristics curve for the prediction of vaginal delivery was 0.865 (95% confidence interval (CI) 0.75-0.98) using HPD as the test variable and the area under the curve was 0.877 (95% CI 0.77-0.99) for AOP. The median HPD was lower in the women delivering vaginally than in the women delivering by cesarean section (P<0.001). HPD was ≤40 mm in 18 (50%) women, of whom all delivered vaginally. HPD was >40 mm in the other 18 women, of whom 8 (22.2%) delivered vaginally (P<0.001). AOP was ≥105° in 22 (61.1%) women and, of these, 21 delivered vaginally. AOP was <105° in the other 14 (38.9%) women, of whom 5 delivered vaginally (P<0.001).Conclusions: HPD ≤40 mm and AOP ≥105° are both predictive of vaginal delivery in the first stage of labor.
