BACKGROUND Instrumental deliveries are commonly performed in the United Kingdom and Ireland, with rates of 12 - 17% in most centres. Knowing the exact position of the fetal head is a pre-requisite for safe instrumental delivery. Traditionally, diagnosis of the fetal head position is made on transvaginal digital examination by delineating the suture lines of the fetal skull and the fontanelles. ...

objectives comparing the effects of spontaneous pushing in the lateral position with the valsalva maneuver during the second stage of labor on maternal and fetal outcomes. methods inclusion criteria in this randomized clinical trial conducted in iran were as follows: nulliparous mothers, live fetus with vertex presentation, gestational age of 37 - 40 weeks, spontaneous labor, and no complicatio...

BACKGROUND Umbilical cord prolapse is an obstetric complication associated with high perinatal morbidity and mortality. A few interventions may improve fetal outcome. In developed countries these have advanced to giving intrauterine fetal resuscitation. Conditions in low resource settings do not allow for some of these advanced techniques. Putting the mother in knee chest position and immediate...

We investigated the role of foetal spine position in the first and second labour stages to determine the probability of OPP detection at birth and the related obstetrical implications. We conducted an observational-longitudinal cohort study on uncomplicated cephalic single foetus pregnant women at term. We evaluated the accuracy of ultrasound in predicting occiput position at birth, influence o...

Observations were made on 475 fetuses carried by 71 pregnant rabbits. 63 or 88.7 per cent of the 71 does were sacrificed from 28 to 31 days after the last fertile mating, and these does bore 401 or 88.2 per cent of the total of 455 fully developed fetuses. The following information was available with reference to each fetus: age, weight, weight of corresponding placenta, horn, i.e., right or le...

OBJECTIVE To investigate the interobserver agreement on the intrapartum ultrasonographic definition of the fetal occipital position. METHODS In 60 singleton pregnancies in labor at term the fetal occipital position was determined by transabdominal ultrasound by two appropriately trained sonographers who were not aware of each other's findings. The Bland-Altman plot was performed and the 95% l...

OBJECTIVE The aim of this study was to determine the effects of period of gestation and position of fetal neck on nuchal translucency measurement. MATERIALS AND METHODS Nuchal translucency was measured in the mid-sagittal plane, with the fetal neck in the flexed, neutral, and extended positions in 100 pregnant women between 11 and 13(+6) weeks. Mean nuchal translucency measurements at differe...
