The outcome of macrosomic infants weighing at least 4500 grams: Los Angeles County + University of Southern California experience.
To describe the maternal and neonatal outcome of macrosomic infants weighing at least 4500 g. ⋯ Vaginal delivery is a reasonable alternative to elective cesarean for infants with estimated birth weights of at least 4500 g, and a trial of labor can be offered.

Multicenter Study Comparative StudyThe origin and outcome of preterm twin pregnancies.
To define the etiology of preterm twin births and determine the contribution of twin births to preterm birth and related morbidity and mortality. ⋯ Twins accounted for a disproportional amount of preterm birth and associated morbidity and mortality. Also, when preterm twins were compared with preterm singletons and corrected for their gestational ages, the rates of morbidity were similar. Preterm twins weighing less than 1000 g did not have an increased prevalence of major handicaps at 1 year of age compared with preterm singletons.

Randomized Controlled Trial Clinical TrialHeparin versus normal saline as a peripheral line flush in maintenance of intermittent intravenous lines in obstetric patients.
To compare heparin sodium (100 United States Pharmacopeia U/mL) with 0.9% sodium chloride for use in the maintenance of intermittent intravenous (IV) devices during pregnancy. ⋯ During pregnancy, dilute heparin flush to maintain patency of intermittent IV site devices results in the following: a greater catheter patency rate at 48 and 72 hours after insertion of the catheter, a lower rate of catheter complications requiring therapy, and no alteration in PTT.

Clinical TrialContinuous monitoring of fetal oxygen saturation by pulse oximetry.
To compare spectrophotometric saturation values of fetal blood sampling to the saturation readings by pulse oximetry. ⋯ Fetal pulse oximetry corresponds satisfactorily to results from fetal blood analysis. Low invasiveness and continuous monitoring are the advantages of this method. At present, the available sensor generates only a limited amount of signal time. However, in combination with FHR monitoring, pulse oximetry promises greatly improved detection of fetal hypoxia.

To describe eight cases of postpartum women who developed seizures associated with post-dural puncture headache. ⋯ We propose that cerebral vasoconstriction is the mechanism for post-dural puncture headaches and seizures. Anatomic brain displacement may incite this vasospasm. This mechanism could also be the cause of cranial nerve palsies that have been described after dural puncture.
