Investigators will perform a multicentric randomized controlled trial comparing the effect of transabdominal and transperineal ultrasound in pregnant women in the second stage of labor, in whom it was decided an operative delivery. Our objective is to evaluate the impact of intrapartal ultrasound measurements, as an auxiliary to clinical evaluation, in the efficacy of an instrumental delivery.

Transabdominal ultrasound, for determining fetal head position, is performed with the pregnant women in supine position after bladder emptying, with the transducer placed transversely on the suprapubic region of the maternal abdomen. For the sonographic determination of the fetal descent we will perform a transperineal ultrasound achieved by placing the ultrasound transducer on the perineum in a mid sagittal position between the labia below the pubic symphysis.
