Methods of placental separation
There are two methods of separation and expulsion of the placenta.
Shultze Method: 80%: This is the most common method. Inthis method separation starts from the centre of the placenta and with the aid of Retroplacenta clot the placenta drop into the lower uterine segment or into the vagina. During delivery the fetal surface appears first at the vulva followed by the membranes. There is minimal blood loss with this method. The 3rd stage is neat
Mathews Duncan Method 20%: In this method separationstarts at the edge and slides down sideways. It comes through
the vulva with the lateral border first, like a button through a button hole. The maternal surface is seen first at the vulva. There is trickling of blood throughout the third stage. The third stage .is messier.
Control of bleeding: the Contraction and retraction of theuterine muscle fibers that bring about separation of the placenta also act as “living Ligatures” by compress ing the blood vessels and controlling the bleeding. The clothing mechanism is of little value untill later when contractions are much less. The opposite wall are now in contact and apply further pressure on the placenta site.
