OBG · Postpartum hemorrhage: retained placenta
Sample itemAfter birth, the placenta has not delivered and heavy bleeding continues despite a firm uterus. Which cause of postpartum hemorrhage is most likely?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Retained placental tissue
The four Ts of postpartum hemorrhage include tone, trauma, tissue, and thrombin. A firm uterus with undelivered placenta and bleeding points toward tissue, such as retained placenta.
Option by option
A. Uterine atony
Atony causes a boggy poorly contracted uterus.
B. Deep-vein thrombosis
DVT does not cause uterine hemorrhage.
C. Retained placental tissue (correct)
Correct. Retained tissue prevents normal placental separation and contraction at the implantation site.
D. Uterine inversion only
Inversion causes a mass and severe pain or shock, not simply an undelivered placenta.
