Comparative StudyA comparison of hemodynamic data derived by pulmonary artery flotation catheter and the esophageal Doppler monitor in preeclampsia.
This study was undertaken to compare hemodynamic data derived with the esophageal Doppler monitor against those obtained with a pulmonary artery flotation catheter in women with complicated preeclampsia. ⋯ In women with preeclampsia the esophageal Doppler monitor consistently underestimated cardiac output by approximately 40%. It is not known whether the apparent increase in accuracy among the women >40 years old arose by chance or reflected a real improvement in performance. The esophageal Doppler monitor accurately reflected the direction and magnitude of the changes in cardiac output with time.

The Preterm Prediction Study: prediction of preterm premature rupture of membranes through clinical findings and ancillary testing. The National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network.
Our objective was to determine the relative importance of demographic characteristics, clinical risk factors, and ancillary screening tests in the prediction of preterm birth as a result of premature rupture of membranes. ⋯ The combination of short cervical length, previous preterm birth caused by preterm premature rupture of membranes, and positive fetal fibronectin screening results was highly associated with preterm delivery caused by preterm premature rupture of membranes in the current gestation.

ReviewAlternatives to mifepristone regimens for medical abortion.
Alternatives to regimens with mifepristone and a prostaglandin analog for medical abortion emerged because of the need for accessible, effective, and safe options in areas of the world where mifepristone was unavailable. Studies of oral or intramuscular methotrexate combined with misoprostol have demonstrated complete abortion rates in the same range as mifepristone regimens at

As early medical abortion becomes more widespread in the United States, those who wish to provide it need to understand how existing abortion restrictions apply to this procedure. Although these laws were written with a primary regard for surgical procedures, most will be broadly applicable to the provision of medical abortion as well. ⋯ We discuss the applicability of such requirements to medical abortions and describe how providers of medical abortion can comply. Finally, we address potential legislative and regulatory changes that could help to make medical abortion more widely accessible to women in the United States.

Case ReportsSuccessful application of extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation as lifesaving therapy for a patient with amniotic fluid embolism.
A woman in labor was noted to have amniotic fluid embolism. Extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation were performed post partum, and the vital signs became stable. The ensuing recovery was uneventful. We conclude that extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation should be considered to save the life of a patient with amniotic fluid embolism and left ventricular failure unresponsive to medical therapy.
