Overview

In the managing of labor, the obstetrician gets often to the border situations especially at the end of the second stage of labor, where only accurate diagnosis allows the make correct decisions on how to end the delivery. Since clinical vaginal examination does not always give complete informations about station and rotation of the head, the intrapartum fetal ultrasound showing the fetus inside the birth canal can refine and document the diagnosis and help us to decide.

Key words:
obstructed labor, ultrasound, rotation, station of the head, forceps, Caesarean section, stage of labor.
