Umbilical cord blood gas analysis in augmented labour.

Labour augmentation with oxytocin may produce an excessive increase in frequency, duration or strength in uterine contractions which may result in fetal stress. Umbilical cord acid-base assessment provides an objective parameter in evaluating the neonatal condition immediately after delivery. We evaluated the neonatal condition in 235 deliveries where oxytocin was used for labour augmentation.

Intrapartum surveillance of IUGR fetuses with cardiotocography and fetal pulse oximetry.

Objective: To investigate the efficacy and safety of intrapartum fetal pulse oximetry, as a predictor of metabolic acidosis at birth of fetuses with intrauterine growth retardation (IUGR).

Study Design: We studied 18 IUGR fetuses (group I) and a control group of 30 appropriate for gestational age (AGA) fetuses (group II) during labor. Both groups had abnormal fetal heart rate tracings and were monitored simultaneously throughout labor with cardiotocography and fetal pulse oximetry.

The value of transvaginal ultrasonography in diagnosis and management of cervical incompetence.

To determine the value of transvaginal sonography in women with a previous history of second trimester miscarriage due to cervical incompetence, 55 patients were subjected to either elective cervical cerclage or follow-up (every second patient) with weekly evaluations of the cervix by transvaginal ultrasonography. Emergency cerclage was applied when significant cervical changes were noted. All patients were evaluated with cervical cultures and ultrasound.

Maternal plasma leptin levels and their relationship to insulin and glucose in gestational-onset diabetes.

To investigate the changes in leptin levels and the relationship between this substance and insulin and glucose in pregnant women with gestational-onset diabetes, we measured plasma leptin levels in the maternal peripheral vein of 17 healthy and 17 diabetic women at 29 and 33 weeks of gestation. We also correlated maternal plasma leptin levels in diabetic women with fasting plasma insulin levels and plasma glucose levels obtained 1 h after oral administration of 50 g of glucose. Maternal serum leptin levels in women with gestational diabetes (mean +/- SD 16.

Sweeping of the membranes versus uterine stimulation by oxytocin in nulliparous women. A randomized controlled trial.

The aim of this study was to evaluate whether sweeping of the membranes at term could shorten the length of pregnancy and reduce the incidence of postterm pregnancies. We randomly selected 104 nulliparas with uncomplicated pregnancy and gestational age between 281 and 287 days. Our patients were divided into three groups.
