“…No beneficial effect of anterior occiput position could be detected in predicting successful IOL as well. It seems that clinical models with combined consideration of maternal factors and ultrasound measurements are needed for a proper prediction of successful vaginal delivery for each individual [42, 43]. …”

BackgroundBy increased concerns about the accuracy of the traditional methods to predict outcomes after induction of labor, developing new standards has a great clinical importance. Here, we compared the predictive value of translabial ultrasound measurements with Bishop Score to determine the suitability of induction of labor.MethodsA homogenous population of primigravid women was recruited. Induction of labor was performed with low-dose infusion of oxytocin. Translabial ultrasound and assessment of Bishop Score were performed by two different obstetricians. Receiver–operating characteristics curves were obtained to measure area under curve and subsequently, test sensitivity of each method.ResultsOne hundred women entered the investigation. Maternal body mass index was significantly higher among candidates of Cesarean section (P: 0.02). Maternal age and fetus weight, gender and occiput position were not determinants of outcomes of induction of labor. Cervical length and fetal head-pubis symphysis distance measured by translabial ultrasound had a test sensitivity of 90 and 88 %, respectively which were slightly higher than sensitivity of Bishop score (84 %).ConclusionThis study demonstrates that translabial measurements can be a suitable alternative method to monitor labor progress with an admissible predictive value compared with Bishop Score. It is a non-invasive method which provides valuable objective measurements and can be better accepted by women when considering the painful process which is required in evaluating Bishop Score.

“…Molina et al [7], among other authors [13,14], evaluated the reproducibility of the different ultrasound parameters used to assess the evolution of delivery and concluded that the angle of descent is the most reproducible parameter for measuring fetal head progression during labor, whereas Duckelmann et al [10], showed that the determination of this ultrasound parameter is also independent of the professional's experience.…”

Objective: The aim of this study was to investigate the role of the 'angle of progression' (AOP) in the prediction of vaginal delivery and establish a cut-off value.Method: 101 pregnant women were included in this prospective study. They were admitted in labor to our hospital and had singleton cephalic presentations and full-term pregnancies. AOP was measured at admission time. We analyzed the results of all the women included but also a subgroup of 66 singleton pregnant women whose assessment of the AOP was performed at the beginning of the second stage of labor.Results: Ninety-one patients had a vaginal delivery (90%) and 19 a cesarean section (10%).The area under the curve was 0.85 (95% confidence interval [CI], 0.77-0.92)and the value of the AOP that optimizes the curve was 125º (S 67.1% E 100%). In the subgroup that was assessed at the second stage of labor, the area under the curve was 0.97 (95%CI,0.90-0.99) and a value of the AOP that optimizes the curve was also 125º (S 91.38% E 100%). Conclusions:The angle of progression is a simple and reliable intrapartum ultrasound parameter for the evaluation of fetal head descent. Transperineal ultrasound assessment could help to decide the method of delivery. In our experience, the sensitivity of the ultrasound measurement increases when this is taken in the second stage of childbirth.

“…76 In a prospective observational study with 202 term nulliparous women, they identified that factors, such as maternal age, history of cesarean section, Bishop score and bladder position on valsalva had an ability of up to 87% to discriminate between normal vaginal delivery and operative delivery. The initial ultrasound parameters taken into account were Anterior vaginal wall relaxation determined by translabial ultrasound after bladder emptying, 77 the descent of the bladder wall (the lowest point reached by any part of the bladder) observed on maximal Valsalva maneuver, ultrasound engagement of the fetal head and cervical length determined translabially.…”

Ultrasound is a crucial part of everyday obstetrical practice and becomes more and more important in the management of traditionally clinical aspects of obstetrics, such as management of labor and delivery, offering a possibly more objective method of examination. The rate of labor induction has doubled in the last two decades and more objective methods are needed to assess the possible outcome of an induction and help clinicians in order to counsel women appropriately. Regarding the management of labor there is extensive evidence that clinical assessment during labor is not accurate, with potential consecutive major implications in the decision-making and the prognosis of the delivery mode. Several studies have shown that ultrasound is an objective method of assessing labor and its progress and is very helpful in decision-making for instrumental deliveries. The purpose of this article is to review the evidence available in literature regarding the benefits and the role in general of ultrasonography in prelabor and labor.
