Is it time for midwives to do intrapartum ultrasound in the delivery ward?

In the last 40 years, intrapartum ultrasound (IU) has been a technique often used in the delivery ward. Many studies are reported in literature about it. According to literature, the IU improves especially the diagnosis of fetal head position (FHP) during the labor, in comparison with traditional digital vaginal examination (DVE). ISUOG practice guidelines highlighted high levels of evidence and grades of recommendation, in particular for the sonographic confirmation of FHP in the pelvis before OVD. IU is currently used in the delivery room for FHP labor diagnosis with VE. The caput succedaneum in labor limits the DVE of FHP diagnosis because reduces the digital examinations of sutures and fontanels. Some authors demonstrate that angle of progression (AOP), head-perineal distance (HPD), and head-symphysis distance (HSD) are important to determine fetal head station during labor. It is time for IU use by midwives together with obstetricians because it improves the traditional VE in the FHP diagnosis.
