TLDR
A new algorithm is developed, applied to intrapartum US and based on suitable US pictures, that sets out the quantitative evaluation, in degrees, of the occiput posterior position of the fetal head in the pelvis and the birth canal in the first and second stage of labor.Abstract:
The determination of fetal head position can be useful in labor to predict the success of labor management, especially in case of malpositions. Malpositions are abnormal positions of the vertex of the fetal head and account for the large part of indication for cesarean sections for dystocic labor. The occiput posterior position occurs in 15-25% of patients before labor at term and, however, most occiput posterior presentations rotate during labor, so that the incidence of occiput posterior at vaginal birth is approximately 5-7%. Persistence of the occiput posterior position is associated with higher rate of interventions and with maternal and neonatal complications and the knowledge of the exact position of the fetal head is of paramount importance prior to any operative vaginal delivery, for both the safe positioning of the instrument that may be used (i.e. forceps versus vacuum) and for its successful outcome. Ultrasound (US) diagnosed occiput posterior position during labor can predict occiput posterior position at birth. By these evidences, the time requested for fetal head descent and the position in the birth canal, had an impact on the diagnosis of labor progression or arrested labor. To try to reduce this pitfalls, authors developed a new algorithm, applied to intrapartum US and based on suitable US pictures, that sets out, in detail, the quantitative evaluation, in degrees, of the occiput posterior position of the fetal head in the pelvis and the birth canal, respectively, in the first and second stage of labor. Authors tested this computer system in a settle of patients in labor.read more

TL;DR: A systematic approach consisting of a combination of transabdominal and transperineal scans is proposed and the findings that allow an accurate diagnosis of normal and abnormal position, flexion, and synclitism of the fetal head are described.

Can the intrapartum ultrasonography reduce the legal liability in distocic labor and delivery
TL;DR: The main advantages of using an intrapartum ultrasonography are: improvement of fetal head’s malposition diagnosis; prevention of maternal and fetal complications of childbirth due to the use of forceps or vacuum extractor; a more accurate planning of cesarean section; a proof of professional correctness.

TL;DR: The modified Sims position is a maternal posture intervention efficient in POP rotation, which decreases cesarean delivery rate and is a simple and noninvasive intervention, reproducible, and well tolerated by pregnant women.

Intrapartum fetal head position I: comparison between transvaginal digital examination and transabdominal ultrasound assessment during the active stage of labor.
TL;DR: Using ultrasound assessment as the gold standard, transvaginal digital determination of fetal head position during active labor demonstrates an overall high rate of error (76%) and may serve as an educational tool for physicians in training.

Investigation of occiput posterior delivery by intrapartum sonography
TL;DR: To investigate if occiput posterior delivery is the consequence of persistence of an initial occipUT posterior position or malrotation from an initial Occiput anterior or transverse position, a large number of animals have been fitted with EMTs.
