“…Blasi et al [6] showed that the diagnostic sonographic accuracy of the foetal occiput position assessment at the second stage of labour had a sensitivity of 100%, specificity of 78%, positive predictive value (PPV) of 26%, and negative predictive value (NPV) of 100% to predict the same position at birth. Considering the foetal spinal position, ultrasound showed a sensitivity of 100%, specificity of 98%, PPV of 85%, and NPV of 100% [6].…”

We investigated the role of foetal spine position in the first and second labour stages to determine the probability of OPP detection at birth and the related obstetrical implications. We conducted an observational-longitudinal cohort study on uncomplicated cephalic single foetus pregnant women at term. We evaluated the accuracy of ultrasound in predicting occiput position at birth, influence of fetal spine in occiput position during labour, labour trend, analgesia request, type of delivery, and indication to CS. The accuracy of the foetal spinal position to predict the occiput position at birth was high at the first labour stage. At the second labour stage, CS (40.3%) and operative vaginal deliveries (23.9%) occurred more frequently in OPP than in occiput anterior position (7% and 15.2%, resp.), especially in cases of the posterior spine. In concordant posterior positions labour length was greater than other ones, and analgesia request rate was 64.1% versus 14.7% for all the others. The assessment of spinal position could be useful in obstetrical management and counselling, both before and during labour. The detection of spinal position, more than OPP, is predictive of successful delivery. In concordant posterior positions, the labour length, analgesia request, operative delivery, and caesarean section rate are higher than in the other combination.

“…Nevertheless, most occiput posterior positions at delivery are the initial occiput posterior position rather than misrotation from an original occiput anterior or transverse position [5,6]. Several recent studies support this notion of POPP as the main cause of occiput posterior delivery, although the concept of malrotation of the initial occiput anterior or transverse position for POPP prevailed even until approximately a decade ago [5,7,8]. …”

“…Blasi et al [7] suggest that the positions of the head and spine during the second stage of labor could be practical indicators for predicting the occiput posterior position at delivery. In their prospective cohort study, 100 singleton pregnant women underwent intrapartum ultrasound during the first and second stages of labor, and the positions of the fetal head and spine were defined.…”

The last step of a successful pregnancy is the safe delivery of the fetus. An important question is if the delivery should vaginal or operative. In addition to the use of conventional antenatal ultrasound, the use of intrapartum ultrasound to evaluate fetal head station, position, cervical ripening, and placental separation is promising. This review evaluates and summarizes the usefulness of intrapartum ultrasound for the evaluation of labor progress and predicting successful operative vaginal delivery.

“…Blasi et al [5] have shown in a pilot study that the final head positions in labor can be predicted by following the spine and head position during the second stage of labor. The authors showed that if the fetal back was posterior at the second stage of labor and the fetal head position was OP, the head would probably not rotate to OA position during delivery.…”

Fetal head progression during labor is difficult to assess. Digital examination has been shown to be an inaccurate method. Utilizing the ultrasound technology in the delivery room can standardize the way we assess head progression. Intrapartum ultrasound is applicable, for the assessment of the progression of labor and assists the obstetrician, in decision making regarding the need for an assisted delivery. This article summarizes the latest studies regarding the usage of ultrasound in the delivery room and the measurements that are used during delivery.
