Worldwide, the gold standard method to monitor the labor progress is by using vaginal examination. Digital vaginal examination (DVE) is considered subjective, as it depends mainly on the experience of the examiner and is affected by the circumstances of the examination .WHO recommended the usage of partogram as a response to high level of fetal and maternal morbidity and mortality rates because of slow labor progress.
Trans-perineal ultrasonography (TPUS) has been investigated to be a complementary tool to manage labor. Studies have shown great reliability of TPUS for evaluation of cervical dilatation, position of the fetal head and its station.
Authors have found that the usage of TPUS alone when DVE is not a preferable method as in conditions of premature rupture of the amniotic membranes or in preterm labor. TPUS has proved to be better accepted and convenient to laboring mothers than DVE.
Correlation of the provided sono-partorgam data in the study to the fetal outcome helps to reduce fetal morbidity and mortality. The Apgar score enables a convenient method to report the condition of the newborn baby immediately after delivery and can evaluate how the response to resuscitation will be if it is needed.
