Epidural analgesia and fetal head malposition at vaginal delivery.
To determine if nulliparas who delivered with on-demand epidural analgesia are more likely to have malpositioning of the fetal vertex at delivery than women delivered during a period of restricted epidural use. ⋯ Providing on-request labor epidural analgesia to nulliparas in spontaneous labor did not result in a clinically significant increase in the frequency of fetal head malpositioning at vaginal delivery.

Multicenter StudyImmunologic studies in presumed amniotic fluid embolism.
To evaluate the potential role of immunologic mechanisms that involve mast cell degranulation (anaphylaxis) or complement activation in the mechanism of amniotic fluid embolism. ⋯ Serologic findings suggest a role for complement activation in the mechanism of amniotic fluid embolism. Laboratory data from this series did not implicate mast cell degranulation (anaphylaxis) in the pathophysiology of the disease.

Multicenter StudyPregnancy-related mortality from preeclampsia and eclampsia.
To examine the role of preeclampsia and eclampsia in pregnancy-related mortality. ⋯ The continuing racial disparity in mortality from preeclampsia and eclampsia emphasizes the need to identify those differences that contribute to excess mortality among black women, and to develop specific interventions to reduce mortality from preeclampsia and eclampsia among all women.
