“…One could argue that the mean difference of 0.12 cm between both measuring techniques for CD in the latent stage group still appears to be acceptable. A meta-analysis showed that correlation of TPU and DE was higher in multigravida women than in nulliparous women [36]. As we did not differentiate between nulliparous and multiparous women, this may also have led to lower correlations.…”

The aim was to compare transperineal ultrasound (TPU) with parameters of the Bishop Score during the first stage of labour and evaluate how TPU can contribute towards improving labour management. Digital examination (DE) and TPU were performed on 42 women presenting at the labour ward with regular contractions. TPU measurements included the head–symphysis distance, angle of progression, diameter of the cervical wall, cervical dilation (CD) and cervical length (CL). To examine if TPU can monitor labour progress, correlations of TPU parameters were calculated. Agreement of DE and TPU was examined for CL and CD measurements and for two groups divided into latent (CD < 5 cm) and active stages of labour (CD ≥ 5 cm). TPU parameters indicated a moderate negative correlation of CD and CL (Pearson: r = −0.667; Spearman = −0.611). The other parameters showed a weak to moderate correlation. DE and TPU measurements for CD showed better agreement during the latent stage than during the active stage. The results of the present study add to the growing evidence that TPU may contribute towards an improved labour management, suggesting a combined approach of TPU and DE to monitor the latent first stage of labour and using only DE during the active stage of labour.

“…They concluded that the utility of transperinal USG for nulliparous women needs further study. 26 This may be due to the fact that different investigators with various levels of experience were involved in these studies that were pooled together and the measurement of cervical dilatation by digital examination was highly subjective. None of the studies, however, interpreted arrest of dilatation as measured by USG as one of the labor abnormalities as classified by Freidman, but the same definitions that were applied for arrest of dilatation can be used when the dilatation is measured by USG and that can be shown by plotting on a sonopartogram.…”

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.

Background: The First-time mothers and their unborn babies rely heavily on skilled management of labour progression. Vaginal exams (VE) are the gold standard for gauging cervical dilation and foetal head position. The purpose of this research was to examine how useful transperineal ultrasonography (TPUS) is for tracking labour. Methods: Thirty-six first-time mothers were included in this prospective observational research. All of the women were at least 18 years old and carrying a single baby during 37 to 41 weeks' gestation. After doing a transvaginal ultrasound (TPUS), the doctor took notes on the mother's cervical dilatation, the foetal head descent, and the head position of the baby. The results of the VE were compared to these measures. The average age of the participants was determined to be 33 years and 7.4 months. The average body mass index was 27.31.3 kg/m2. The average gestational age was 39 weeks and 1 day. There was a favourable connection between the foetal head station as measured by VE and the Head-perineum distance as measured by US (p0.001). There was a favourable connection between the foetal head station as measured by VE and the Headperineum distance as measured by US (p0.001). Women were more likely to comply with and be satisfied with TPUS (66.7% vs. 38.9% with VE, p 0.001) than males were with VE. In conclusion, TPUS shows potential as a safe and user-friendly method for tracking the development of labour in first-time mothers. Our results show that TPUS measures correlate well with traditional vaginal checks at many time points during childbirth.
