Fetal malpositions and cephalic malpresentations are well-recognized causes of failure to
progress in labor. They frequently require operative delivery, and are associated with an …

ABSTRACT PURPOSE AND SCOPE The purpose of these Guidelines is to review the
published techniques of ultrasound in labor and their practical applications, to summarize …

Background: The fetal occiput posterior position poses challenges in every aspect of
intrapartum care—prevention, diagnosis, correction, supportive care, labor management …

Objective To investigate the ability of intrapartum translabial sonography to diagnose fetal
station in the second stage of labor. Methods Patients with uncomplicated pregnancies at …

Background Safe management of the second stage of labor is of great importance.
Unnecessary interventions should be avoided and correct timing of interventions should be …

Objective To investigate if fetal head–perineum distance and angle of progression
measured with two‐dimensional (2D) and three‐dimensional (3D) transperineal ultrasound …

Objective. To identify maternal and fetal risk factors associated with persistent occiput
posterior position at delivery, and to examine the association of occiput posterior position …

Objective Accurate prediction of whether a nulliparous woman will have a vaginal delivery
would be a major advance in obstetrics. The objective of the study was to develop such a …

Background: Hands‐and‐knees positioning during labor has been recommended on the
theory that gravity and buoyancy may promote fetal head rotation to the anterior position and …

Background To date, no research has focused on the sonographic quantification of the
degree of flexion of the fetal head in relation to the labor outcome in women with protracted …
