Abstract

For many years, diagnostic ultrasound has had a place in the labor ward. Recently, it has also been applied to assess birth progress. Initially, the position of the fetal spine and occiput was assessed by transabdominal ultrasound and correlated with vaginal palpation to improve detection of OP presentation. From 2005, translabial ultrasound was used, initially before [3, 4] but then also during labor [5–10] to measure head station objectively. Studies of accuracy of vaginal palpation, measured using a phantom, showed that obstetric vaginal palpation is very operator dependent and, overall, not accurate; this applies to palpated head stations expressed in centimeters above or below the mid-pelvis (Fig. 9.1) and simply as “high,” “mid,” and “low,” according to the ACOG classification [11].
