Intraumbilical vein injection of prostaglandin F-2 alpha in retained placenta

A randomized protocol was used to study the effect of intraumbilical prostaglandin F-2 alpha (Hembate, Upjohn) and oxytocin injection in women with retained placenta. Prostaglandin F-2 alpha, 20 mg, diluted to 20 ml in normal saline solution (10 women, group 1); 30 IU of oxytocin, diluted to 20 mi in normal saline solution (11 women, group 2). or 20 mi of normal saline solution alone (7 women, group 3): were injected into the umbilical vein 1 h after delivery. Nine women (group 4, controls) underwent manual removal of the retained placenta. In group 1, placental expulsion occurred in all patients and the duration of the placental expulsion after prostaglandin F,a injection was 6.8 +/- 1.36 (mean +/- SE) min: in group 2, six placental expulsions occurred after 13.3 +/- 1.97 min (mean +/- SE); and in group 3, no effect was recorded after intraumbilical saline injection. We suggest that intraumbilical vein injection of prostaglandin F-2 alpha might be a beneficial, non-surgical method for treating retained placenta. Oxytocin might reduce the Incidence of manual lysis of the placenta and achieve partial success.
