摘要Objectives: To evaluate the feasibility, reliability and agreement of serial transperineal ultrasound (TPU) assessment of fetal head station (para-sagittal angle of progression [psAOP], head-perineum distance [HPD], head-symphysis distance [HSD]) and sonographic cervical dilatation (SCD), compared to fetal head station and cervical dilatation determined by vaginal examination, respectively.
Methods: This was a prospective longitudinal study in singleton pregnancies undergoing induction of labor at term. Paired assessment of fetal head station and cervical dilatation by vaginal examination, with transperineal ultrasound assessment of psAOP, HPD, HSD and SCD were made serially. Feasibility, correlation, reliability and agreement were determined.
Results: 1,139-paired measurements amongst 326 women were included. psAOP and HPD were achievable in all assessments. HSD was not achievable in 3.4% (11/326) due to high fetal head station. Fetal head station by vaginal examination was positively correlated with psAOP (rho=0.70) but negatively correlated with HPD (rho=-0.57) and HSD (rho=-0.52). The feasibility to measure SCD reduced as cervical dilatation increased. Cervical dilatation and SCD were positively correlated (rho=0.96) with strong agreement (concordant correlation coefficient=0.925).
Conclusions: Measurements of psAOP and HPD are feasible and correlate significantly with fetal head station by vaginal examination. Measurement of HSD is not feasible when fetal head station is high. Measurement of SCD is feasible, though, it is more difficult in advanced stage of labor. The correlation, reliability and agreement between SCD and cervical dilatation by vaginal examination are high.
