Randomized, Double-Blinded Trial of Magnesium Sulfate Tocolysis versus Intravenous Normal Saline for Preterm Nonsevere Placental Abruption.

Objective To evaluate the efficacy and safety of magnesium sulfate in the resolution of vaginal bleeding and contractions in nonsevere placental abruption. Study Design Thirty women between 24 and 34 weeks of gestation diagnosed with nonsevere placental abruption were randomized to receive magnesium sulfate tocolysis or normal saline infusion. The primary outcome was the proportion of women undelivered at 48 hours with resolution of vaginal bleeding and uterine contractions. Maternal and neonatal outcomes were also compared. Results Fifteen (50%) women received magnesium sulfate tocolysis and 15 (50%) received intravenous saline. There was no difference in the number of women who were undelivered at 48 hours with resolution of vaginal bleeding and contractions in the magnesium sulfate (80.0%) and saline (66.7%; p-value = 0.68) groups. There were no differences between groups in the gestational age at randomization, time to uterine quiescence, time on study drug, length of hospitalization, days from randomization to delivery, incidence of side effects, or admissions to the neonatal intensive care unit. Conclusions Magnesium sulfate tocolysis did not provide a significant difference in pregnancy prolongation in the management of preterm nonsevere placental abruption. Recruitment goals were not met due to the introduction of the use of magnesium sulfate for neuroprotection.

Nonpneumatic antishock garment combined with bakri balloon as a nonoperative "uterine sandwich" for temporization of massive postpartum hemorrhage from disseminated intravascular coagulation.

Disseminated intravascular coagulation (DIC) is an uncommon but potentially catastrophic complication of postpartum hemorrhage. We describe two cases of massive postpartum hemorrhage complicated by DIC that were successfully temporized with combined use of the Bakri balloon and nonpneumatic antishock garment (NASG) during massive transfusion. In the first case, a healthy, term gravida underwent emergent cesarean for fetal bradycardia during labor induction. 10 minutes after completion of surgery, brisk vaginal hemorrhage of nonclotting blood from fulminant DIC resulted in maternal shock. A Bakri balloon and NASG were placed during massive transfusion, resulting in rapid maternal stabilization. In the second case, a healthy, term gravida suffered an amniotic fluid embolism during labor requiring emergent cesarean delivery and complicated by cardiac arrest with successful resuscitation. Postoperative rapid uterine bleeding from DIC was treated with a Bakri balloon and NASG, stabilizing the patient during massive transfusion. Neither patient required further surgical procedures. NASG combined with Bakri balloon may serve as a valuable nonoperative treatment or temporization option in cases of massive postpartum hemorrhage complicated by coagulopathy such as these. Further study of the utility of NASG in high-resource settings is warranted.
