Distinguishing RPOC from natural postpartum lochia or uterine atony
is not easy.
was the most common reason for EOH in this study, followed by morbidly adherent placenta.
In a study, packing was performed due to postpartum bleeding associated with uterine atony
but hypogastric artery ligation was not performed in one of three patients in whom the Kittipat method was performed (11).
One of our subject end up in uterine atony
and surgical treatment was opted.

Although uterine atony
following a spontaneous vaginal delivery is the most frequent reason for PPH, other pregnancy-related emergent conditions may also lead to rapid blood loss .
The predominant cause of MT was uterine atony
(mostly due to multiple gestation, uterine leiomyomas, and chorioamnionitis) throughout the 10-year period, which accounted for 55% of the MTs, followed by placental abnormalities (placenta previa, placenta accreta, and placental abruption) at 29%, laceration (uterine rupture) at 11%, and coagulation dysfunction (amniotic embolism) at 5%.
In grand multiparas due to decrease in muscular tissues and increase in fibrous tissues of uterus, uterine atony
is more common.
PP with or without PA and uterine atony
were the main cause of PPH in this study, as well as in control groups.
It is generally caused by four major conditions- tone (uterine atony
), trauma, tissue (retained placenta), Thrombin (coagulopathy).
At the pathological level, the causes of excessive bleeding at CD are uterine atony
(commonly after prolonged labour), uterine trauma (excessive bleeding from uterine incision or additional tears laterally into the broad ligament or vertically down the lower segment) and placental site bleeding (associated with placenta praevia, previous CD and/or morbidly adherent placenta).
is the most common cause of PPH (70%), but genital tract trauma (i.e.
