Transabdominal fetal pulse oximetry with near-infrared spectroscopy.
The purpose of this study was to determine the feasibility of noninvasive fetal pulse oximetry in the human fetus with transabdominal continuous-wave near-infrared spectroscopy. ⋯ This preliminary data indicate that transabdominal fetal pulse oximetry is feasible for human patient application. The measured values were similar to those that are obtained with transvaginal pulse oximetry. Future studies should correlate transabdominally obtained measurements with those measurements that are obtained by transvaginal fetal pulse oximetry.

The purpose of this study was to determine risk assessments for a spectrum of neonatal outcomes with elective cesarean delivery versus a trial of labor for previous cesarean section and otherwise healthy patients who deliver at term. ⋯ For otherwise healthy patients at term, the risk of adverse neonatal outcomes is low, with the choice between elective cesarean delivery and trial of labor in general balancing the low risk of increased respiratory morbidity and thereby neonatal intensive care unit triage/admission against the extremely low risk of labor-related infant death and severe morbidity. However, this balance for the patients with previous cesarean delivery appears shifted, with less benefit from a trial of labor in terms of reduced respiratory morbidity and neonatal intensive care unit triage/admission and with increased labor-related severe morbidity/death, albeit with all of these still at a low level.

Insulin and glyburide therapy: dosage, severity level of gestational diabetes, and pregnancy outcome.
We sought to investigate the association between glyburide dose, degree of severity in gestational diabetes mellitus (GDM), level of glycemic control, and pregnancy outcome in insulin- and glyburide-treated patients. ⋯ Glyburide and insulin are equally efficient for treatment of GDM in all levels of disease severity. Achieving the established level of glycemic control, not the mode of pharmacologic therapy, is the key to improving the outcome in GDM.

Randomized Controlled Trial Clinical TrialA randomized trial of plasma volume expansion in hypertensive disorders of pregnancy: influence on the pulsatility indices of the fetal umbilical artery and middle cerebral artery.
The purpose of this study was to investigate the effect of plasma volume expansion on the pulsatility indices of the fetal umbilical and middle cerebral arteries. ⋯ Plasma volume expansion did not influence the pulsatility indices of the umbilical and middle cerebral arteries.

Multicenter Study Comparative StudyComparison of "instrument-associated" and "spontaneous" obstetric depressed skull fractures in a cohort of 68 neonates.
A depressed skull fracture is an inward buckling of the calvarial bones and is referred to as a "ping-pong" fracture. This study aimed to look at differences between "spontaneous" and "instrument-associated" depressed skull fractures. ⋯ Depressed skull fractures occur in the setting of spontaneous and operative deliveries, although the incidence is higher in the latter case. Depressed skull fractures that are associated with instrumental deliveries are significantly more likely to be associated with intracranial lesions. Persistent disabilities are rare.
