“…This study is consistent with the study conducted in Ethiopia [34], and China [35]. This is might be due to the fact that higher the station, the longer the duration of labor and the higher the risk of operative delivery [36].…”

Background: For a majority of women who have had one prior lower segment caesarean section Vaginal delivery after caesarean section is proper route of delivery. However, little is known about vaginal delivery after caesarean section in Ethiopia. Objectives:To determine the magnitude and associated factors of successful vaginal birth after one cesarean section in University of Gondar Comprehensive Specialized Hospital.Methods: Institutional based cross-sectional study was conducted among 409 women who were randomly selected and had one previous cesarean section delivery and underwent trial of labor. Data was analyzed and computed using Stata version 14 Software. Multivariable logistic regression analysis was performed to identify the factors associated with successful vaginal birth after caesarean section. A crude and adjusted odds ratio with a 95% confidence interval was used to interpret the results. A P value of < 0.05 indicated statistically significant results.Results: Of 385 completed charts reviewed, the success rate of vaginal birth after cesarean section was 38.2%, (95%CI; 33.3%-43.1%). The factors associated with successful vaginal birth after cesarean section were: Prior history of spontaneous vaginal delivery at any point time (AOR = 1.84, 95% CI; 1.02-3.33), prior successful vaginal birth after previous cesarean section (AOR = 2.12, 95%CI; 0.97-4.64), no history of still birth (AOR = 1.78, 95% CI; 1.03-3.07), cervical dilation on admission ≥ 3 cm (AOR = 2.22, 95% CI; 1.14-4.35), station on admission ≥ 0 (AOR = 1.94, 95% CI; 1.12-3.37), and Antenatal care follow-up (AOR = 2.48,95% CI; 1.26-4.88). Conclusions:The finding of current study was lower than other previous studies conducted in Ethiopia. Therefore, strong endeavour is needed to reduce repeated caesarean section among women who had one previous lower segment caesarean section by considering the above identified factors.

“…Fetal station and cervical dilatation are closely interlinked. The fetal presenting part at complete dilatation of the cervix was, according to findings of Ashwal et al, at or below the ischial spines in 91.9% of nulliparous women and 80.3% of multiparous women [23], which limits interpretation of which factor constitutes the risk.…”

“…The fetal head station is the most important parameter and its assessment at the beginning of the second stage is significantly and independently associated with the duration of the second stage and correlated with the risk of operative delivery in both nulliparous and multiparous women (p < 0.001). 36 Perineum-toskull USG distance (HPD) measurement of ≥40 mm (measured in 659 women) was significantly associated with the occurrence of a difficult extraction based on the composite criterion, after adjustment for parity, presentation type, and fetal macrosomia. 37 The cutoff parameters taken in the second stage of labor to predict success are AOP >120°, HPD <2-5 cm, MLA <45°, and head-up sign.…”

Traditionally, progress of labor and the prediction of vaginal delivery is done by clinical assessment. There is a lot of subjectivity in assessment and increased interobserver variability, especially with digital vaginal examination. For the past two decades, many ultrasonographic parameters were developed, and their utility was studied objectively. Of the ultrasound (USG) parameters, head position is the easiest to recognize. The descent and station of the head are determined indirectly by angle of progression (AOP) and head perineal distance (HPD). Cervical dilatation does not correlate well with digital vaginal examination, and it is difficult to visualize cervical rim beyond 8-cm dilatation. Midline angle and head-up position are other parameters in the second stage of labor that are determined to predict difficult vaginal delivery. Angle of progression of >110° and HPD <4 cm are good predictors of vaginal delivery. "Sonopartogram" may replace the traditional partogram as it is more objective, noninvasive, and women-friendly. Intrapartum apps are incorporating USG parameters with other patient characteristics to develop models for predicting vaginal delivery.
