Abstract
Background: Progress of labor has been assessed by digital vaginal examination (VE). We introduce the concept of a non-intrusive ultrasound (US)-based assessment of labor progress (the ‘sonopartogram’) and investigate its feasibility for assessing cervical dilatation and fetal head descent and rotation.
Aim of the Work: To evaluate the accuracy of the transperineal ultrasound in detecting the cervical dilation in relation to VE
. Patients and Methods: This prospective observational study was carried out in Ain Shams University Maternity Hospital on 40 pregnant women at third trimester planned to undergo digital VE and transperineal 2D-US during the period from December 2016 to May 2017.
Results: There is very strong correlation between the cervical dilatation by VE and by US. [Pearson’s r =.8601, 95% CI = 0.7493 to 0.9240, p-value <.0001, r2 = 0.7396] (Fig. 12).
Conclusion: The agreement between digital VE and US was good for cervical dilatation, head rotation and caput but less so for head descent.
Recommendations: Intrapartum translabial ultrasound examination is a useful, an objective tool to assess the progress of labor.
