The Importance of the Novel Postpartum Uterine Ultrasonographic Scale in Numerical Assessments of Uterine Involution Regarding Perinatal Maternal and Fetal Outcomes.

By standardizing uterine involution in a numerical fashion, we precisely demonstrate that uterine involution varied with the method of delivery (vaginal/cesarean) and with the number of vials of oxytocin received intrapartum, but not with the number of vials of ergometrine maleate received, and not with the origin of the parturient (rural/urban).
