Is maternal posturing during labor efficient in preventing persistent occiput posterior position? A randomized controlled trial.
OBJECTIVE We sought to evaluate the efficacy of maternal posturing during labor on the prevention of persistent occiput posterior (OP) position. STUDY DESIGN We conducted a randomized trial including 220 patients in labor with a single fetus in documented OP position. Main outcome was the proportion of anterior rotation from OP position. RESULTS The rates of anterior rotation were, respecti...
متن کاملInstrumental Rotation for Persistent Fetal Occiput Posterior Position: A Way to Decrease Maternal and Neonatal Injury?
OBJECTIVE To evaluate immediate perineal and neonatal morbidity associated with instrumental rotations performed with Thierry's spatulas for the management of persistent posterior occiput (OP) positions. METHODS Retrospective study including all persistent occiput posterior positions with vaginal OP delivery, from August 2006 to September 2007. Occiput anterior deliveries following successful...
متن کاملInvestigation of occiput posterior delivery by intrapartum sonography.
OBJECTIVE To investigate if occiput posterior delivery is the consequence of persistence of an initial occiput posterior position or malrotation from an initial occiput anterior or transverse position. METHODS This was a cross-sectional study involving transabdominal sonography to determine fetal occipital position in 918 singleton pregnancies with cephalic presentation in active labor at 37-...
متن کاملNeonatal outcomes of deliveries in occiput posterior position when delayed pushing is practiced: a cohort study
BACKGROUND To examine the impact of occiput posterior position, compared to occiput anterior position, on neonatal outcomes in a setting where delayed pushing is practiced. The specific aim was to estimate the risk of acidaemia. METHODS Cohort study from a university hospital in Sweden between 2004 and 2012. Information was collected from a local database of 35,546 births. Umbilical artery sa...
متن کاملThe association between persistent fetal occiput posterior position and perinatal outcomes: an example of propensity score and covariate distance matching.
In a retrospective cohort study of 18,880 full-term, cephalic singletons born in San Francisco, California, during 1976-2001, the authors used multivariable logistic regression (MVLR) and propensity score analysis (PSA) to examine the association between persistent fetal occiput posterior (OP) position and perinatal outcomes. The principles and applications of these techniques are compared and ...
