Correct Answer � A
Explanation
|
|
Matthews Duncan method involves marginal separation of the placenta during the third stage of labour. The placenta separates from the margins first, then peels towards the center—a physiological mechanism for placental separation post-delivery. Blood escapes externally early due to immediate bleeding. This method is common with a non-contracted uterus and results in less efficient placental expulsion.
Incorrect Options:
– B. Central separation: Known as the Schultz mechanism, placenta separates from the center first, forming a retroplacental clot which assists further separation. Bleeding is delayed.
– C. Controlled contraction: Involves uterotonic administration (e.g., oxytocin) and controlled cord traction—part of active management, not linked to the Matthews Duncan method.
– D. Reposition of uterus inversion: Refers to manual procedures like the Johnson maneuver, not the Matthews Duncan method.
