In the Schultz mechanism of placental delivery, which side is presented at the introitus?

In the Schultz mechanism of placental delivery, it is the fetal side of the placenta that presents at the introitus. This mechanism is characterized by the placenta being expelled in a way that the smooth fetal surface comes out first, often seen as the membranes being intact until the very end of the delivery process. The fetal side, also called the chorionic surface, is typically shiny and covered with the amniotic membranes, giving it a distinct appearance compared to the rough maternal side.

The significance of the Schultz mechanism lies in its implications for maternal and fetal outcomes, as the fetal side presenting first can help minimize the risk of retained placental tissue, which can lead to complications. Understanding this mechanism aids midwives and healthcare providers in managing the third stage of labor effectively.
