Therefore, a lack of uterine muscle contraction can lead to an acute hemorrhage, as the vasculature is not being sufficiently compressed. Uterine atony is the most common cause of postpartum hemorrhage, which is an emergency and potential cause of fatality.
Thus, if there are no uterine muscle contractions, it can lead to a severe hemorrhage because the blood vessels are not being compressed properly. Uterine atony is the most common cause of postpartum hemorrhage, which could be an emergency situation that poses a risk of fatality.
