OBJECTIVES: to assess the obstetrical and psychological effect of visual biofeedback using trans-perineal ultrasound (TPU) during the second stage of labor. METHODS: Visual biofeedback using TPU was performed prospectively during the second stage of labor in twenty-six low risk nulliparous women. Pushing efficacy was assessed by the angle of progression at rest and during pushing efforts before and after observing the ultrasound screen. Obstetrical outcomes included level of perineal tearing, mode of delivery and length of the second stage...

OBJECTIVE: To study patterns of induced labor at term in hypertensive women. STUDY DESIGN: We performed a retrospective cohort study using the Consortium on Safe Labor database; a multicenter study of labor and delivery practices from electronic medical records in 19 hospitals. 55,572 women were studied: 28,254 nulliparas and 27,318 multiparas, undergoing induction of labor at term without a prior cesarean with a singleton vertex live born fetus. Four hypertensive groups were defined: chronic hypertension (n=1164), gestational hypertension (n=1861), preeclampsia (n=1513) and superimposed preeclampsia (n=655), compared to controls (no hypertension, n=50,379)...

The main complication of diabetes is Diabetic retinopathy (DR), retinal vascular disease and it leads to the blindness. Regular screening for early DR disease detection is considered as an intensive labor and resource oriented task. Therefore, automatic detection of DR diseases is performed only by using the computational technique is the great solution. An automatic method is more reliable to determine the presence of an abnormality in Fundus images (FI) but, the classification process is poorly performed...

Episiotomy is obstetric procedure during which the incision extends the vestibule of the vagina during the second stage of labor. Episiotomy was extensively spread with gradual increase of rates in the first half of the 20th century and was performed medio-laterally in all nulliparous women with the idea to protect fetal head from trauma and pelvic floor from injuries. However, reports claiming that episiotomy had no such benefits were published. It was shown that routine medio-lateral episiotomy did not protect against the appearance of urinary incontinence after vaginal delivery, while the risk of anal incontinence could be increased...

Obstetricians who care for twin pregnancies should be aware of the challenges that may arise during the labor and delivery. With recognition of these issues and proper training, providers should be able to help women with twin pregnancies achieve a safe delivery for them and their babies. With the use of breech extraction of the second twin and active management of the second stage of labor, women with twin pregnancies can also achieve a high vaginal delivery rate of both twins.

REVIEW
Yvonne W Cheng, Aaron B Caughey
The American College of Obstetricians and Gynecologists (ACOG) Practice Bulletin No. 49 on Dystocia and Augmentation of Labor defines a prolonged second stage as more than 2 hours without or 3 hours with epidural analgesia in nulliparous women, and 1 hour without, or 2 hours with epidural in multiparous women. This definition diagnoses 10% to 14% of nulliparous and 3% to 3.5% of multiparous women as having a prolonged second stage. Although current labor norms remained largely based on data established by Friedman in the 1950s, modern obstetric population and practice have evolved with time...

The analysis of the temporal dynamics in intrapartum fetal heart rate (FHR), aiming at early detection of fetal acidosis, constitutes an intricate signal processing task, that continuously receives significant research efforts. Entropy and entropy rates, envisaged as measures of complexity, often computed via popular implementations referred to as Approximate Entropy (ApEn) or Sample Entropy (SampEn), have regularly been reported as significant features for intrapartum FHR analysis. The present contribution aims to show how mutual information enhances characterization of FHR temporal dynamics and improves fetal acidosis detection performance...

OBJECTIVE: Vietnamese clinicians routinely perform episiotomies in the belief that 3rd-4th degree tears may be prevented, based partly on the view that Vietnamese women have a short perineal length that puts them at increased risk of tears. However, there is no evidence to suggest Vietnamese women have a short perineum compared with other populations. We aimed to determine the mean perineal length among Vietnamese women in early labor and in the second stage, and to compare this to findings from similar studies in other populations...

BACKGROUND: In 2010 the Consortium on Safe Labor published labor curves. It was proposed that the rate of cesarean delivery could be lowered by avoiding the diagnosis of arrest of dilation before 6 cm. However, there is little information on the uptake of the guidelines and on changes in cesarean delivery rates that may have occurred. OBJECTIVE: The objective of the study was to test the following hypotheses: (1) among patients laboring at term, rates of arrest of dilation disorders have decreased, leading to a decrease in the rate of cesarean delivery; (2) in the second stage, pushing duration prior to diagnosis of arrest of descent has increased, also leading to a reduction in the rate of cesarean delivery for this indication...
