Abstract
PURPOSE Labor is shorter in multiparous women. However, there are no individualized data on differences in duration of labor for consecutive deliveries in the same parturient. METHODS We conducted a retrospective data analysis from 2004 to 2021 at the University Hospital of Zurich and included all women with 2 or more vaginal deliveries of a singleton child in cephalic position, between 22 and 42 weeks of gestation. Descriptive statistics were performed with SPSS version 25.0 (IBM, SPSS Inc., USA). The primary endpoint was the ratio between durations of labor stages in consecutive deliveries of the same parturient. RESULTS A total of 3344 women with 7066 births (2601 first [P0], 2987 s [P1], 1176 third [P2], and 302 fourth [P3]) were included. The ratio of duration of the active first stage of labor between P1 and P0 was 0.49 (95% CI 0.47-0.51, p < 0.001) meaning that the active first stage of labor was 51% shorter. The second stage of labor with a ratio of 0.26 (95% CI 0.24-0.27, p < 0.001) was 74% shorter in P1 compared to P0. Higher birthweight of the first child led to an even greater decrease in duration of the second stage of labor in P1 compared to P0 (p = 0.003). Neuraxial anesthesia was an independent risk factor for a longer duration of labor, irrespective of parity (p < 0.001). Birthweight and HC of the neonates did not significantly differ between the children born by the same women. However, higher birthweight in of the first child significantly augmented the rate of second stage of labor between P0 and P1 (p = 0.003). DISCUSSION Up to the third delivery, duration of labor decreased with each consecutive delivery of the same parturient. An individualized assessment of the expected duration of labor in multiparous women should be encouraged.

Abstract
Background Some evidence indicates that maternal analgesia during labor may have adverse effects on neonates due to exposure to specific drugs or the potential effects of analgesia on the course of labor. We assessed the clinical outcome of term neonates born to mothers who received epidural analgesia (E) or systemic analgesia with remifentanil (R) during labor. Methods Data was collected retrospectively over one year. We have evaluated the medical records of 247 full-term neonates; 208 were born to mothers who received E and 39 to mothers who received R. Data on Apgar scores and neonatal complications (perinatal asphyxia, respiratory distress, infection, hyperbilirubinemia, and birth injuries), and average hospital stay were collected. Mann-Whitney U test, chi-square test, and logistic regression analysis were used where appropriate. Results The values of the mean Apgar scores between E and R at 1 and 5 minutes were similar (8.83 vs. 8.97, p = 0.252; 9.81 vs. 9.87, p = 0.762, respectively). The average length of neonatal hospitalization did not differ between groups (4.19 vs. 4; p = 0.557). The percentages of neonates with any complication were similar between groups (28.3% vs. 32.5%, p = 0.598). Neonates born by cesarean delivery (CD) had significantly worse outcomes than those born vaginally (p = 0.008, OR 2.8, 95% CI [1.30, 6.17]). Conclusion We did not find a statistically significant difference in mean Apgar scores and neonatal complications between neonates who received epidural vs. remifentanil analgesia. An increased rate of complications in neonates born via CD was found. Future studies should have a larger sample size and be powered to detect associations in these findings.

[PMID: 33039395 DOI: 10.1016/j.ajog.2020.10.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 09/25/2020] [Accepted: 10/02/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Ultrasound measurements offer objective and reproducible methods to measure the fetal head station. Before these methods can be applied to assess labor progression, the fetal head descent needs to be evaluated longitudinally in well-defined populations and compared with the existing data derived from clinical examinations. OBJECTIVE This study aimed to use ultrasound measurements to describe the fetal head descent longitudinally as labor progressed through the active phase in nulliparous women with spontaneous onset of labor. STUDY DESIGN This was a single center, prospective cohort study at the Landspitali - The National University Hospital of Iceland, Reykjavik, Iceland, from January 2016 to April 2018. Nulliparous women with a single fetus in cephalic presentation and spontaneous labor onset at a gestational age of ≥37 weeks, were eligible. Participant inclusion occurred during admission for women with an established active phase of labor or at the start of the active phase for women admitted during the latent phase. The active phase was defined as an effaced cervix dilated to at least 4 cm in women with regular contractions. According to the clinical protocol, vaginal examinations were done at entry and subsequently throughout labor, paired each time with a transperineal ultrasound examination by a separate examiner, with both examiners being blinded to the other's results. The measurements used to assess the fetal head station were the head-perineum distance and angle of progression. Cervical dilatation was examined clinically. RESULTS The study population comprised 99 women. The labor patterns for the head-perineum distance, angle of progression, and cervical dilatation differentiated the participants into 75 with spontaneous deliveries, 16 with instrumental vaginal deliveries, and 8 cesarean deliveries. At the inclusion stage, the cervix was dilated 4 cm in 26 of the women, 5 cm in 30 of the women, and ≥6 cm in 43 women. One cesarean and 1 ventouse delivery were performed for fetal distress, whereas the remaining cesarean deliveries were conducted because of a failure to progress. The total number of examinations conducted throughout the study was 345, with an average of 3.6 per woman. The ultrasound-measured fetal head station both at the first and last examination were associated with the delivery mode and remaining time of labor. In spontaneous deliveries, rapid head descent started around 4 hours before birth, the descent being more gradual in instrumental deliveries and absent in cesarean deliveries. A head-perineum distance of 30 mm and angle of progression of 125° separately predicted delivery within 3.0 hours (95% confidence interval, 2.5-3.8 hours and 2.4-3.7 hours, respectively) in women delivering vaginally. Although the head-perineum distance and angle of progression are independent methods, both methods gave similar mirror image patterns. The fetal head station at the first examination was highest for the fetuses in occiput posterior position, but the pattern of rapid descent was similar for all initial positions in spontaneously delivering women. Oxytocin augmentation was used in 41% of women; in these labors a slower descent was noted. Descent was only slightly slower in the 62% of women who received epidural analgesia. A nonlinear relationship was observed between the fetal head station and dilatation. CONCLUSION We have established the ultrasound-measured descent patterns for nulliparous women in spontaneous labor. The patterns resemble previously published patterns based on clinical vaginal examinations. The ultrasound-measured fetal head station was associated with the delivery mode and remaining time of labor.

Abstract
BACKGROUND The fetal head malposition in labor leads to prolonged labor, cesarean delivery and increased perinatal morbidity. Epidural analgesia has been associated with fetal head malposition, but it remains unknown if this relation is causal. OBJECTIVE To compare the incidence of fetal malposition during labor and maternal/fetal outcomes, between women who received epidural analgesia with those who did not use the analgesic method. STUDY DESIGN Case control study including 500 women with a single fetus in vertex position who gave birth at term at the Policlinic Hospital of Modena between May 2019 and July 2019. Two-hundred and fifty women belonged to the epidural analgesia (EA) group and 250 to the control group. RESULTS The rate of posterior occiput positions occurred 4 times more frequently in the EA group than in the control group (8.8% vs 2.2%, p = .004). Cesarean sections were significantly higher in the EA group (11.6% vs 1.6%, p < .0000) as well as the need for augmentation with oxytocin (20% vs 8%, p = .0001) compared to the control group, in which spontaneous delivery prevailed instead. Women with epidural had labors that lasted on average 7.0 h against the 3.30 h of controls (p < .0000). The length of 2nd stage of labor was 55 vs 30 min (p = .009), respectively. No differences in blood loss and Apgar score between groups. Early breastfeeding was significantly higher among controls (82% vs 92.8%, p = .0004). CONCLUSIONS Women receiving epidural analgesia in labor have higher rate of fetal malposition, prolonged labors, and more cesarean sections than controls. However, further studies are required to confirm a causal association between EA and fetal head malposition.

Abstract
Background/aim Knowledge regarding pain relief during labor remains insufficient. We aimed to determine and compare the effectiveness and safety of epidural analgesia, combined spinal–epidural analgesia, and parenteral meperidine on both mothers and fetuses. Materials and methods This study was designed as an observational case-control study. We collected prospective data from patients whose labor pain management was conducted with meperidine in addition to retrospective cohort data of neuraxial methods; 138 patients were enrolled. Epidural analgesia group consisted of 68 patients, whereas combined spinal-epidural (CSE) analgesia group and meperidine group consisted of 50 and 20 patients, respectively. We compared the delivery patterns, labor durations, pain levels, side effects, maternal satisfaction levels, and neonatal outcomes of the various pain management methods. Results Patient demographics, duration of first, second, and third labor stages, and instrumental delivery rates were comparable among groups (P > 0.05). Cesarean section tended to be less frequent in the CSE group. In the meperidine group, visual analog scale (VAS) values and sedation were significantly higher (P < 0.001) and maternal satisfaction lower (P < 0.001). Hypotension tended to be more frequent in the meperidine group. APGAR scores at the 1st and 5th min were similar among the groups and between meperidine subgroups defined by three different administration times (<1 h, 1‒4 h, ≥4 h; P > 0.05). Conclusion Neuraxial methods had no effect on instrumental delivery rates. CSE represented a near significant risk reduction in cesarean section. Our results demonstrated that regional analgesia methods were reasonably safe for both mother and fetus, and regional analgesia methods resulted in greater maternal satisfaction and pain control compared to meperidine.

Abstract
Purpose Labor analgesia is part of the most important tasks an anesthesiologist needs to deal with. With the “two-child policy” in China, the number of parturients has increased significantly, labor analgesia more should be valued. There has been a tremendous change on labor analgesia research in China and around the world; however, broader trends in the prevalence and scope of labor analgesia research remain underexplored. The current study quantitatively analyzes trends in labor analgesia research publications in the past 30 years. Methods A bibliometric approach was used to search Scopus, PubMed, Web of Science and the China National Knowledge Infrastructure for all labor analgesia-related research articles. The research progress and growing trend were quantitatively analyzed by total publications, research types, research institutions, journal impact factors, and author’s contribution. Total citations frequency, average citations per item and h-index were used for evaluating literature quantity. Results From 1988 to 2018, over 8000 documents in labor analgesia research field were published worldwide. According to Scopus, 68.2% papers of all documents were articles. The USA published the largest number of articles (2204, 27.45%). China had published 175 articles (2.18%), ranking the 11th. According to WOS, there were 221 research categories for labor analgesia articles all over the world. The total citations were 76,207, average 9.086 citations per item, and the h-index was 114, average 14 citations per item worldwide. The total citations and h-index of papers published in China were as follows: 353 total citations, 7.06 citations per item, and 10 h-index. High contribution journals, authors, institutions and the top 10 most cited articles on labor analgesia in the world and China were also listed. Conclusion Labor analgesia research has grown markedly during the 1988–2018 period. Although China had made remarkable achievements, there was a gap in the high-quality studies between China and other leading countries.

Abstract
OBJECTIVE To assess the effect of a modified definition of dystocia and of a different timing of interventions during spontaneous labor on the rate of oxytocin use and on its consequences on labor outcome. METHODS We compared oxytocin use and labor outcome before and after the introduction of a new protocol for the management of spontaneous labor. By protocol, oxytocin use and/or artificial rupture of the membranes was restricted to cases without progress in cervical dilatation for≥1h and/or no progress of fetal descent for≥1h at full dilatation. The main outcome measure was the rate of oxytocin use. Secondary outcome criteria were the consequences on labor (duration of labor, tachysystole and uterine hyperstimulation, abnormal fetal heart rate, cesarean delivery rate) and neonatal outcome. RESULTS Oxytocin use was strongly reduced from 2015 (69.2%) to 2016 (39.8%; P<0.01) and 2017 (31.9%; P<0.01). Abnormal FHR rates decreased simultaneously (respectively 52%, 37% et 29%, P<0.05), as well as uterine hyperstimulation (respectively 33.6%, 21.3% et 23.0%; P<0.05). The cesarean delivery rate did not vary significantly from 2015 (11.5%) to 2016 (8.4%; NS) but it decreased from 2015 to 2017 (11.5% to 2.6%, respectively; P<0.05). No difference was found in postpartum hemorrhage rates or in neonatal outcome. The duration of labor was significantly longer for women who delivered in 2017, compared with 2015 (372 minutes versus 306 minutes, respectively; P<0.05). After multivariate analysis, FHR abnormalities were reduced (aOR 0.65 IC 95% [0.49-0.86]) as well as cesarean deliveries during labor (aOR 0.5 IC 95% [0.26-0.97]) in 2017 only, compared with the reference year 2015. CONCLUSION A simple and easy-to-use definition of dystocia and of interventions required during labor allowed a strong reduction of oxytocin use during labor with subsequent benefits such as reduced rates of FHR abnormalities, uterine hyperstimulations and cesarean deliveries, at the cost of a limited prolongation of labor, mainly in nulliparous women.

Abstract
BACKGROUND Women's experience of pain during labor varies greatly, and pain control is a major concern for obstetricians. Several methods have been studied for pain management for women in labor, including drug and non-drug interventions. OBJECTIVE To test the hypothesis that in nulliparous women with singleton pregnancies at term, listening to music would reduce the pain level during labor. METHODS Parallel group non-blinded randomized clinical trial conducted at a single center in Italy. Nulliparous women in spontaneous labor with singleton pregnancies and vertex presentation admitted in labor and delivery room between 37 0/7 and 42 0/7 weeks of gestation for active phase of labor were eligible, and were randomized in a 1:1 ratio to receive music during labor or no music during labor. Music in labor was defined listening to music from the randomization until the delivery of the baby. The primary endpoint was the pain level during the active phase of labor, recorded using the visual analogue scale (VAS) for pain, ranging from 0 (no pain) to 10 (unbearable pain). The effect of music use during labor on each outcome was quantified as the mean difference (MD) with 95% confidence interval (CI). RESULTS During the study period, 30 women agree to take part in the study, underwent randomization, and were enrolled and followed up. 15 women were randomized in the music group, and 15 in the control group. No patients were lost to follow up for the primary outcome. Pain level during the active phase of labor was scored 8.8 ± 0.9 in the music group, and 9.8 ± 0.3 in the control group (MD - 1.00 point, 95% CI - 1.48 to - 0.52; P < 0.01). Music during labor and delivery was also associated with a decreased pain at 1 h postpartum (MD - 2.40 points, 95% CI - 4.30 to - 0.50), and decreased anxiety level during active phase of labor (MD - 19.90 points, 95% CI - 38.72 to - 1.08), second stage of labor (MD - 49.40 points, 95% CI - 69.44 to - 29.36), and at 1 h postpartum (MD - 27.00 points, 95% CI - 47.37 to - 6.63). CONCLUSION In nulliparous women with singleton pregnancies at term, listening to music reduces the pain level, and the anxiety level during labor. TRIAL REGISTRATION Clinicaltrials.gov NCT03779386.

Abstract
BACKGROUND The first stage of labor is significantly longer with epidural analgesia use, implying an alteration in uterine contractility. Although the pre-epidural fluid bolus is used with every epidural and affects as many as 80% of laboring women, its effects on uterine contraction parameters are unknown. DESIGN Using a retrospective descriptive repeated measures design, we compared uterine contraction parameters including frequency, duration, peak intensity, resting tone, and Montevideo units at baseline and during the intravascular pre-epidural fluid bolus (Bolus) epochs for healthy laboring women at term gestation undergoing augmentation or induction. METHOD Contraction parameters were compared using data from fetal monitor strips with intrauterine pressure catheter instrumentation. RESULTS No significant differences were found between epochs for women receiving constant Pitocin dosages (n = 10) using Wilcoxon signed rank tests at .05 α level, but all parameters trended in the direction of improved contractility except frequency, which was unchanged. CONCLUSIONS These pilot study findings do not support the proposal that the pre-epidural fluid bolus is a contributor to decreased uterine contractility in any parameter. It is possible that the bolus improved myometrial perfusion and metabolic function in the contracting and resting states in less hydrated women.

Abstract
BACKGROUND The traditional approach to the assessment of labor progress is by digital vaginal examination; however, it is subjective and imprecise. Recent studies have investigated the role of transperineal ultrasonographic assessment of fetal head descent by measuring the angle of progression and head-perineum distance. OBJECTIVE The objective of this study was to evaluate factors that affected labor progress, which were defined by the transperineal ultrasonographic parameters, in women who achieved vaginal delivery. STUDY DESIGN This was a prospective longitudinal study performed in 315 women with singleton pregnancy who underwent labor induction at term between December 2016 and December 2017. Paired assessment of cervical dilation and fetal head station by vaginal examination and transperineal ultrasonographic assessment of fetal head descent (parasagittal angle of progression and head-perineum distance) were made serially after the commencement of labor induction until full cervical dilation. The researchers were blinded to the findings of the clinical team's vaginal examination and vice versa. The repeated measure data were analyzed by mixed effect models to identify the significant factors (age ≥35 years, obesity, parity, methods of labor induction, and epidural anesthesia) that affected the relationship between parasagittal angle of progression and head-perineum distance against fetal head station and cervical dilation. RESULTS The total number of paired vaginal examination and transperineal ultrasonographic assessments among the 261 women (82.9%) with vaginal delivery was 945, with a median of 3 per woman. The median assessment-to-assessment interval was 4.6 hours (interquartile range, 4.3-5.2). Multiparity and mechanical methods of labor induction were associated with a faster rate of fetal head descent, which was determined by head-perineum distance against fetal head station, than nulliparity and the use of a slow-release vaginal pessary, respectively. An additional increase of 0.10 cm in head-perineum distance was observed, for an unit increase in fetal head station in nulliparous women (P=.03) and women who had a slow-release vaginal pessary (P=.02), compared with multiparous women and those who had mechanical methods for labor induction. The use of epidural anesthesia was associated with a slower rate of fetal head descent, which was determined by both parasagittal angle of progression and head-perineum distance, against fetal head station. An additional decrease of 3.66 degrees in parasagittal angle of progression (P=.04) and an additional increase in 0.33 cm in head-perineum distance (P≤.001) were observed for a unit increase in fetal head station in women with the use of epidural anesthesia, compared with those without. Obese women had higher head-perineum distance overall, compared with normal weight women; at different cross-sections of time periods, obesity appeared to be associated with a slower rate of change between head-perineum distance and cervical dilation. Advanced maternal age did not affect transperineal ultrasound-determined labor progress (P>.05). CONCLUSION Parity, methods of labor induction, the use of epidural anesthesia, and obesity affect labor progress, which has been illustrated objectively by serial transperineal ultrasonographic assessment of fetal head descent.

Abstract
INTRODUCTION Epidural analgesia may lead to a prolonged second stage, and increased instrumental vaginal deliveries rate in singleton gestations. We aimed to examine the association between epidural and vacuum deliveries rate and second stage duration among twin deliveries. METHODS Retrospective study conducted at a single teaching hospital on data between January 1995 and December 2015. All twin pregnancies, >24 weeks that had a trial of labor were included. Twins with major malformations, intrauterine death, or had a caesarean delivery without a trial of labor, were excluded. Women were divided to those who had an epidural analgesia (group 1) and those who did not (group 2). Primary outcome was vacuum delivery rate. RESULTS Of all 1955 twin pregnancies delivered during the study period, 827 (42.3%) were eligible and included; 332 (40.1%) in group 1 and 495 (59.9%) in group 2. Vacuum delivery rate of any twin was 7.5% and 6.3% in groups 1 and 2, respectively (p = 0.48; Relative Risk 1.20; 95% Confidence Interval: 0.72-2.0). Vacuum delivery rate of first twin only or second twin only did not differ significantly as well. After adjusting for variables that differed significantly between the groups in univariate analysis, second stage duration of first and second twins in group 1 was significantly longer than in group 2 (p = 0.001; ratio=1.66; 95% Confidence Interval: 1.42-1.94 and p = 0.001; ratio=1.40; 95% Confidence Interval: 1.24-1.58, respectively). CONCLUSIONS Epidural use in twin deliveries did not affect vacuum deliveries rate. Epidural was associated with a prolonged second stage of both twins.

Abstract
Background In regard to obstetrical analgesia management there are different results related to the use of epidural analgesia versus mechanical adverse outcomes at delivery. Methods Cohort study of 23,183 consecutive, term, singleton vaginal deliveries, including spontaneous and induced labours, at a single institution from January 2004 to June 2016 to determine the association between epidural analgesia and different mechanical complications affecting maternal health such as severe perineal tears (SPT), abnormal foetal head position at delivery, instrumental delivery and caesarean section (CS). Multivariate logistic regression models were constructed to evaluate the risk factors of these mechanical complications with respect to possible cofounders. Results Epidural analgesia was used in 15,821 (68.24%) women. The logistic regression model showed a non-significant association between the use of epidural analgesia and SPT (odds ratio [OR], 078; 95% confidence interval [CI], 0.48–1.26; p = 0.310). Instrumental delivery and CSs were more frequently performed in cases than controls (p = < 0.001), with OR of 1.19 (95% CI: 1.10–1.29) for CS and with OR of 3.27 (95% CI: 2.93–4.61) for instrumental delivery. The abnormal foetal position head at delivery were significantly lower in the neonates delivered without epidural analgesia compared with those in which epidural analgesia was used (p < 0.001) with OR of 1.43 (95% CI:1.27–1.72). Conclusions Epidural analgesia is not associated with an increase of SPT, but it was an independent risk factor for instrumental delivery, CS and abnormal foetal head position at delivery.

Abstract
Spinal epidural abscess is a rare complication of epidural catheter insertion, with an incidence reported to be as low as 0.02%, but with a high morbidity and mortality. This reflects the difficulty in diagnosis of the condition, as early symptoms and signs are usually non-specific with late neurological manifestations. We report a case of spinal epidural abscess in a diabetic patient who underwent splenectomy and distal pancreatectomy. Early investigation with magnetic resonance imaging was effective in demonstrating an extensive epidural abscess involving the thoracic spine, with extension to the base of the skull and associated cord compression. Extensive multilevel laminectomies with thorough irrigation and washout of the epidural space were successful in treating this patient and preventing the development of permanent neurological sequelae.

Abstract
Obstetric anesthesia has evolved over the course of its history to encompass comprehensive aspects of maternal care, ranging from cesarean delivery anesthesia and labor analgesia to maternal resuscitation and patient safety. Anesthesiologists are concerned with maternal and neonatal outcomes, and with preventing and managing complications that may present during childbirth. The current review will focus on recent advances in obstetric anesthesia, including labor anesthesia and analgesia, cesarean delivery anesthesia and analgesia, the effects of maternal anesthesia on breastfeeding and fever, and maternal safety. The impact of these advances on maternal and neonatal outcomes is discussed. Past and future progress in this field will continue to have significant implications on the health of women and children.

Abstract
BACKGROUND The Journal has had a profound influence in nearly 150 years of publishing. A bibliometric analysis, which uses citation analyses to evaluate the impact of articles, can be used to identify the most impactful papers in the Journal's history. OBJECTIVE The objective was to identify and characterize the top-cited articles published in the Journal since 1920. STUDY DESIGN We used the Web of Science and Scopus databases to identify the most frequently cited articles of the Journal from 1920 through 2018. The top 100 articles from each database were included in our analysis. Articles were evaluated for several characteristics including year of publication, article type, topic, open access, and country of origin. Using the Scopus data, we performed an unadjusted categorical analysis to characterize the articles and a 2 time point analysis to compare articles before and after 1995, the median year of publication from each database list. RESULTS The top 100 articles from each database were included in the analysis. This included 120 total articles: 80 articles listed in both and 20 unique in each database. More than half (52%) were observational studies, 9% were RCTs, and 75% were from US authors. When the post-1995 studies were compared with the articles published before 1995, articles were more frequently cited (median 27 vs 13 citations per year, P < .001), more likely to be randomized (14.0% vs 4.8%, P = .009), and more likely to originate from international authors (33.3% vs 17.5%, P = .045). CONCLUSION Slightly more than half of the top-cited papers in the Journal since 1920 were observational studies and three quarters of all papers were from US authors. Compared with top-cited papers before 1995, the Journal's top-cited papers after 1995 were more likely to be randomized and to originate from international authors.

Effects of Ropivacaine in Patient-Controlled Epidural Analgesia on Uterine Electromyographic Activities during Labor. BIOMED RESEARCH INTERNATIONAL 2018; 2018:7162865.

Abstract
Epidural analgesia is effective in relieving pain during labor. However, concerns as to compromised labor progress and outcomes arise. This study aimed to assess the effect of patient-controlled epidural analgesia (PCEA) with ropivacaine on uterine electromyography (EMG) activities and outcomes in labor. A total of 213 pregnant women were divided into three groups: the PCEA with ropivacaine group (n = 78), the PCEA with levobupivacaine group (n = 66), and a control group that did not receive PCEA (n = 69). Uterine EMG activities were recorded during the first stage of labor. Maternal and fetal outcomes also were assessed. The primary outcomes of this study were EMG activities. No significant differences were observed in patient demographics or neonatal weight among the three groups. Compared to the PCEA with levobupivacaine group, the control and PCEA with ropivacaine groups had lower rates of oxytocin administration (P < 0.05) and shorter durations of the first stage of labor (P < 0.05). For the EMG activities, the PCEA with ropivacaine group showed a higher power (P < 0.01) and higher peak frequency (P < 0.05) than the PCEA with levobupivacaine group. With ropivacaine, the EMG activities remained stable 30–120 min. Compared with levobupivacaine, the use of ropivacaine in PCEA has no suppressive effect on uterine EMG activities during the first stage of labor. In addition, ropivacaine leads to labor progress and delivery outcomes similar to those in the control group, as well as similar and favorable analgesic satisfaction with the use of levobupivacaine.

Abstract
BACKGROUND Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour. However, there are concerns about unintended adverse effects on the mother and infant. This is an update of an existing Cochrane Review (Epidural versus non-epidural or no analgesia in labour), last published in 2011. OBJECTIVES To assess the effectiveness and safety of all types of epidural analgesia, including combined-spinal-epidural (CSE) on the mother and the baby, when compared with non-epidural or no pain relief during labour. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register (ClinicalTrials.gov), the WHO International Clinical Trials Registry Platform (ICTRP) (30 April 2017), and reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials comparing all types of epidural with any form of pain relief not involving regional blockade, or no pain relief in labour. We have not included cluster-randomised or quasi-randomised trials in this update. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risks of bias, extracted data and checked them for accuracy. We assessed selected outcomes using the GRADE approach. MAIN RESULTS Fifty-two trials met the inclusion criteria and we have included data from 40 trials, involving over 11,000 women. Four trials included more than two arms. Thirty-four trials compared epidural with opioids, seven compared epidural with no analgesia, one trial compared epidural with acu-stimulation, one trial compared epidural with inhaled analgesia, and one trial compared epidural with continuous midwifery support and other analgesia. Risks of bias varied throughout the included studies; six out of 40 studies were at high or unclear risk of bias for every bias domain, while most studies were at high or unclear risk of detection bias. Quality of the evidence assessed using GRADE ranged from moderate to low quality.Pain intensity as measured using pain scores was lower in women with epidural analgesia when compared to women who received opioids (standardised mean difference -2.64, 95% confidence interval (CI) -4.56 to -0.73; 1133 women; studies = 5; I2 = 98%; low-quality evidence) and a higher proportion were satisfied with their pain relief, reporting it to be "excellent or very good" (average risk ratio (RR) 1.47, 95% CI 1.03 to 2.08; 1911 women; studies = 7; I2 = 97%; low-quality evidence). There was substantial statistical heterogeneity in both these outcomes. There was a substantial decrease in the need for additional pain relief in women receiving epidural analgesia compared with opioid analgesia (average RR 0.10, 95% CI 0.04 to 0.25; 5099 women; studies = 16; I2 = 73%; Tau2 = 1.89; Chi2 = 52.07 (P < 0.00001)). More women in the epidural group experienced assisted vaginal birth (RR 1.44, 95% CI 1.29 to 1.60; 9948 women; studies = 30; low-quality evidence). A post hoc subgroup analysis of trials conducted after 2005 showed that this effect is negated when trials before 2005 are excluded from this analysis (RR 1.19, 95% CI 0.97 to 1.46). There was no difference between caesarean section rates (RR 1.07, 95% CI 0.96 to 1.18; 10,350 women; studies = 33; moderate-quality evidence), and maternal long-term backache (RR 1.00, 95% CI 0.89 to 1.12; 814 women; studies = 2; moderate-quality evidence). There were also no clear differences between groups for the neonatal outcomes, admission to neonatal intensive care unit (RR 1.03, 95% CI 0.95 to 1.12; 4488 babies; studies = 8; moderate-quality evidence) and Apgar score less than seven at five minutes (RR 0.73, 95% CI 0.52 to 1.02; 8752 babies; studies = 22; low-quality evidence). We downgraded the evidence for study design limitations, inconsistency, imprecision in effect estimates, and possible publication bias.Side effects were reported in both epidural and opioid groups. Women with epidural experienced more hypotension, motor blockade, fever, and urinary retention. They also had longer first and second stages of labour, and were more likely to have oxytocin augmentation than the women in the opioid group. Women receiving epidurals had less risk of respiratory depression requiring oxygen, and were less likely to experience nausea and vomiting than women receiving opioids. Babies born to women in the epidural group were less likely to have received naloxone. There was no clear difference between groups for postnatal depression, headache, itching, shivering, or drowsiness. Maternal morbidity and long-term neonatal outcomes were not reported.Epidural analgesia resulted in less reported pain when compared with placebo or no treatment, and with acu-stimulation. Pain intensity was not reported in the trials that compared epidural with inhaled analgesia, or continuous support. Few trials reported on serious maternal side effects. AUTHORS' CONCLUSIONS Low-quality evidence shows that epidural analgesia may be more effective in reducing pain during labour and increasing maternal satisfaction with pain relief than non-epidural methods. Although overall there appears to be an increase in assisted vaginal birth when women have epidural analgesia, a post hoc subgroup analysis showed this effect is not seen in recent studies (after 2005), suggesting that modern approaches to epidural analgesia in labour do not affect this outcome. Epidural analgesia had no impact on the risk of caesarean section or long-term backache, and did not appear to have an immediate effect on neonatal status as determined by Apgar scores or in admissions to neonatal intensive care. Further research may be helpful to evaluate rare but potentially severe adverse effects of epidural analgesia and non-epidural analgesia on women in labour and long-term neonatal outcomes.

Abstract
PURPOSE The aim of the study was to evaluate the progression and rotation of the fetal head during the second stage of labor using translabial ultrasound and to compare ultrasonographic data obtained in nulliparous women both receiving and not receiving neuraxial analgesia. METHODS The 49 patients enrolled in the study were divided into two groups according to receiving or not receiving neuraxial analgesia. Every half hour from full dilation to delivery, the ultrasonographic translabial parameters of Angle of Progression, Head Symphysis Distance, and Midline Angle were obtained and recorded by a single operator. Then, these records were compared between the two groups of patients. RESULTS Patients that underwent neuraxial analgesia presented with increased duration of the second stage of labor, with mean values of Angle of Progression significantly higher and of Midline Angle significantly lower for each time interval studied compared to patients without analgesia. A borderline significant relationship was found between administration of neuraxial analgesia and Head Symphysis Distance. CONCLUSIONS In this study, we demonstrated that combined spinal-epidural analgesia influences the duration of the second stage of labor and the initial progression and rotation of the fetal head through the birth canal, but not the kind of delivery. A correlation between Angle of Progression values and success in the application of a vacuum has been reported by other authors and confirmed in our study.

Abstract
QUESTION Among women in labour, does sequential application of non-pharmacological interventions relieve labour pain, shorten labour, and delay pharmacological analgesia use? DESIGN Randomised trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Eighty women admitted in labour at the end of a low-risk pregnancy. INTERVENTION Participants in the experimental group received three interventions for up to 40minutes each in particular stages of labour: exercise on a Swiss ball at 4 to 5cm of cervical dilation; lumbosacral massage at 5 to 6cm dilation; and a warm shower at >7cm dilation. Participants in the control group received usual maternity unit care. Participants in both groups were encouraged to try not to avoid or delay use of pharmacological analgesia. OUTCOME MEASURES Pain severity was reported on a visual analogue scale. Maternal and neonatal data were collected from official birth records. Satisfaction with care was recorded with a questionnaire. RESULTS Some participants took analgesic medication before the study was complete, so pain was analysed with a last observation carried forward approach. In this analysis, the experimental group had significantly lower pain severity immediately after: exercises (MD 24mm, 95% CI 15 to 34), massage (14mm, 95% CI 4 to 25), and showering (17mm, 95% CI 5 to 29), which allowed delayed and reduced use of analgesic medication. Other significant benefits included: faster expulsion (MD 18minutes, 95% CI 5 to 30), improved neonatal status, and higher maternal satisfaction. No adverse effects were identified. CONCLUSION This sequence of non-pharmacological interventions significantly reduced labour pain from 4cm to beyond 7cm of cervical dilation, as reflected in decreased and delayed use of analgesic medication. Women in labour could be encouraged to use these interventions, especially if they seek to minimise or delay use of analgesic medication. TRIAL REGISTRATION NCT01389128.

Abstract
OBJECTIVE Patient-controlled epidural analgesia (PCEA), used to relieve pain during delivery, delays labor but the mechanism is unknown. The aim was to investigate the effects of PCEA on uterine and abdominal muscles electromyographic (EMG) activity during the second stage of labor. METHODS This study included 45 nulliparous pregnant women without PCEA, 42 women with standard PCEA treatment given during the first stage of labor and stopped near the end of the first stage, and 22 women with standard PCEA treatment with continued use throughout the first and second stages of labor. The EMG signals were recorded from the abdominal surface using PowerLab hardware and LabChart software (ADInstruments, New South Wales, Australia) and filtered to separate uterine and abdominal EMG. Various EMG burst parameters were obtained. RESULTS There are no differences ( P > .05) in the age, body mass index, fetal weight, and Apgar scores between the patients from the various groups. PCEA (both stopped and continued) inhibits ( P < .05) duration, number of bursts, and root mean square of uterine EMG. PCEA also produces statistically significant ( P < .001) reductions in abdominal EMG. The decrease in EMG activity is accompanied by a significant ( P < .001) prolongation of the second stage duration (PCEA continued = 95.08 ± 8.60 minutes, PCEA stopped = 79.39 ± 6.25 minutes, no PCEA = 61.00 ± 7.23 minutes). CONCLUSION PCEA suppresses uterine and abdominal muscle EMG during the second stage of labor but inhibition depends upon the treatment schedule. PCEA prolongs the duration of labor by inhibition of uterine and abdominal muscle and neural activity.

Abstract
The effects of combined spinal–epidural analgesia (CSEA) and epidural analgesia (EA) were studied in 50 healthy parturients randomly allocated to receive bupivacaine plus fentanyl either epidurally, or intrathecally and epidurally. Significant differences from baseline values were seen in systolic blood pressure at all time-points except for 4 h in the EA group and at 3 and 4 h in the CSEA group. Significant differences from baseline values were seen in diastolic blood pressure at 1, 2, 3 and 4 h in the EA group, whereas no significant differences from baseline were seen in the CSEA group. Pain scores in both groups were significantly decreased compared with baseline and all scores, except at 2h, were significantly lower in the CSEA group compared with the EA group. The duration of labour and total amount of drugs used were significantly decreased and cervical dilatation was faster with CSEA compared with EA. In conclusion, CSEA was associated with more rapid onset of analgesia and faster progress in cervical dilatation compared with EA, and can be used safely for labour analgesia.

Abstract
Current American College of Obstetricians and Gynecologists' definition of prolonged second stage diagnoses 10% to 14% of nulliparous and 3% to 3.5% of multiparous women as having a prolonged second stage. The progression of labor in modern obstetrics may have deviated from the current labor norms established in the 1950s, likely due to differences in obstetric population characteristics and variation in clinical practice. Optimal management of the second stage in women with and without epidural remains debatable. Although prolonged second stage is associated with increased risk of maternal morbidity, conflicting data exist regarding the duration of second stage and associated neonatal morbidity and mortality.

Abstract
The controversy over whether epidurals increase the risk of cesarean has raged since the 1970s. This article provides a history of of the early observational research designed to answer this question and an in-depth analysis of the most recent randomized control trials. Based on the research, the author concludes that we cannot assure women that epidurals do not increase the risk of cesarean.

Abstract
OBJECTIVES Intention-to-treat (ITT) analysis of randomized controlled trials (RCTs) may cause bias when compliance is poor. Noncompliance describes failure to comply with allocation in the intervention arm, and contamination describes uptake of the intervention in the control arm. Instrumental variable (IV) analysis can be applied in addition to the primary ITT analysis to estimate the causal effect adjusted for noncompliance and contamination, assuming that noncompliers would have had the same treatment benefit as compliers. We aimed to compare ITT and IV meta-analysis of the association between epidural analgesia in labor and cesarean section. STUDY DESIGN AND SETTING The study was restricted to 27 trials in a Cochrane Systematic Review. The association between epidural analgesia in labor and cesarean section was calculated using ITT and IV analyses. Pooled risk ratios (RRs) were calculated using fixed-effects meta-analysis. RESULTS In 18 trials with compliance data, noncompliance was 23% and contamination was 27%. In 10 trials with outcome data stratified by compliance, the pooled RR for cesarean section following epidural analgesia was 1.37 [95% confidence interval (CI): 1.00, 1.89; P = 0.049] using IV compared with 1.19 (95% CI: 0.93, 1.51; P = 0.16) using ITT. CONCLUSION ITT meta-analysis underestimates the effect of receiving epidural analgesia in labor on cesarean section compared with IV meta-analysis.

Abstract
OBJECTIVE To describe trends in the use of epidural analgesia (EA) and to evaluate the association of EA with operative deliveries. STUDY DESIGN In this population-based, retrospective cohort study, women with an intention to deliver vaginally of a term, cephalic, singleton between 2000 and 2009 (n=1378458) were included. Main outcome measures were labor EA rates, unplanned caesarean section (CS), and instrumental vaginal delivery (IVD) including deliveries by either vacuum or forceps. Data were obtained from the Perinatal Registry of The Netherlands and logistic regression analyses were used. RESULTS Among nulliparous, EA use almost tripled over the 10-year span (from 7.7% to 21.9%), while rates of CS and IVD did not change much (+2.8% and -3.3%, respectively). Among multiparous, EA use increased from 2.4% to 6.8%, while rates of CS and IVD changed slightly (+0.8% and -0.7%, respectively). Multivariable analysis showed a positive association of EA with CS, which weakened in ten years, from an adjusted OR of 2.35 (95% CI, 2.18 to 2.54) to 1.69 (95% CI, 1.60 to 1.79; p<0.001) in nulliparous, and from an adjusted OR of 3.17 (95% CI, 2.79 to 3.61) to 2.56 (95% CI, 2.34 to 2.81; p<0.001) in multiparous women. A weak inverse association between EA and IVD was found among nulliparous (adjusted OR, 0.76; 95% CI, 0.75 to 0.78), and a positive one among multiparous women (adjusted OR, 2.08; 95% CI, 2.00 to 2.16). Both associations grew slightly weaker over time. CONCLUSIONS A near triplication of EA use in The Netherlands in ten years was accompanied by relatively stable rates of operative deliveries. The association between EA and operative delivery became weaker. This supports the idea that EA is not an important causal factor of operative deliveries.

Abstract
AIMS This study aimed to evaluate the effect of ropivacaine epidural analgesia on duration and outcome of labour in nulliparous parturients of India with parturient not receiving any analgesia. SETTINGS AND DESIGN One hundred and twenty nulliparous parturient in established labour at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group (n=60), whereas those not enthusiastic to labour analgesia were allocated in the control group (n=60). MATERIALS AND METHODS Epidural analgesia was provided by a bolus injection of 10 ml of ropivacaine 0.2% and 50μg fentanyl and maintained by using a continuous infusion of ropivacaine 0.1% with fentanyl 2μl/ml at a 10ml/hour rate. The outcomes were duration of labour, incidence of cesarean sections and instrumental vaginal delivery and neonatal outcome. STATISTICAL ANALYSIS USED Statistical analysis was conducted using unpaired student t-test and chi-square test as required. All tests of significance were performed using two-tailed probability tests. Differences were considered significant when p-value was <0.05. RESULTS The two groups were comparable in terms of socio-demographic data. The mean duration of first stage of labour was shorter in epidural group (4.83 ± 1.59 h) compared with control group (5.48 ± 1.56 h) while the duration of second stage of labour was prolong in epidural group (33.13 ± 12.78 min) as compared to control (27.53 ± 11.73 min). Instrumental vaginal or caesarean delivery rate did not increase in the epidural group. The APGAR scores at 5 min were statistically similar in both groups. CONCLUSION Epidural analgesia by ropivacaine in Indian nulliparous resulted in shorter duration of first stage and prolongs duration of second stage of labour compared with parturients without analgesia; however, instrumental vaginal or caesarean delivery rate does not increase in the epidural group.

Abstract
BACKGROUND Pain during childbirth is arguably the most severe pain some women may experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour. Many women have concerns regarding its safety. Furthermore, epidural services and anaesthetic support may not be available consistently across all centres. Observational data suggest that early initiation of epidural may be associated with an increased risk of caesarean section, but the same findings were not seen in recent randomised controlled trials. More recent guidelines suggest that in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labour. The choice of analgesic technique, agent, and dosage is based on many factors, including patient preference, medical status, and contraindications. There is no systematically reviewed evidence on the maternal and foetal outcomes and safety of this practice. OBJECTIVES This systematic review aimed to summarise the effectiveness and safety of early initiation versus late initiation of epidural analgesia in women. We considered the obstetric and fetal outcomes relevant to women and side effects of the treatments, including risk of caesarean section, instrumental birth and time to birth. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 February 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (January 1966 to February 2014), Embase (January 1980 to February 2014) and reference lists of retrieved studies. SELECTION CRITERIA We included all randomised controlled trials involving women undergoing epidural labour analgesia that compared early initiation versus late initiation of epidural labour analgesia. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, extracted the data and assessed the trial quality. Data were checked for accuracy. MAIN RESULTS We included nine studies with a total of 15,752 women.The overall risk of bias of the studies was low, with the exception of performance bias (blinding of participants and personnel).The nine studies showed no clinically meaningful difference in risk of caesarean section with early initiation versus late initiation of epidural analgesia for labour (risk ratio (RR) 1.02; 95% confidence interval (CI) 0.96 to 1.08, nine studies, 15,499 women, high quality evidence). There was no clinically meaningful difference in risk of instrumental birth with early initiation versus late initiation of epidural analgesia for labour (RR 0.93; 95% CI 0.86 to 1.01, eight studies, 15,379 women, high quality evidence). The duration of second stage of labour showed no clinically meaningful difference between early initiation and late initiation of epidural analgesia (mean difference (MD) -3.22 minutes; 95% CI -6.71 to 0.27, eight studies, 14,982 women, high quality evidence). There was significant heterogeneity in the duration of first stage of labour and the data were not pooled.There was no clinically meaningful difference in Apgar scores less than seven at one minute (RR 0.96; 95% CI 0.84 to 1.10, seven studies, 14,924 women, high quality evidence). There was no clinically meaningful difference in Apgar scores less than seven at five minutes (RR 0.96; 95% CI 0.69 to 1.33, seven studies, 14,924 women, high quality evidence). There was no clinically meaningful difference in umbilical arterial pH between early initiation and late initiation (MD 0.01; 95% CI -0.01 to 0.03, four studies, 14,004 women, high quality evidence). There was no clinically meaningful difference in umbilical venous pH favouring early initiation (MD 0.01; 95% CI -0.00 to 0.02, four studies, 14,004 women, moderate quality evidence). AUTHORS' CONCLUSIONS There is predominantly high-quality evidence that early or late initiation of epidural analgesia for labour have similar effects on all measured outcomes. However, various forms of alternative pain relief were given to women who were allocated to delayed epidurals to cover that period of delay, so that is it hard to assess the outcomes clearly. We conclude that for first time mothers in labour who request epidurals for pain relief, it would appear that the time to initiate epidural analgesia is dependent upon women's requests.

Abstract
Approximately 60% of women who labour in the USA receive some form of neuraxial analgesia, but concerns have been raised regarding whether it negatively impacts the labour and delivery process. In this review, we attempt to clarify what has been established as truths, falsities and uncertainties regarding the effects of this form of pain relief on labour progression, negative and/or positive. Additionally, although the term 'epidural' has become synonymous with neuraxial analgesia, we discuss two other techniques, combined spinal-epidural and continuous spinal analgesia, that are gaining popularity, as well as their effects on labour progression.

Abstract
Este artigo avaliou o uso das boas práticas (alimentação, deambulação, uso de métodos não farmacológicos para alívio da dor e de partograma) e de intervenções obstétricas na assistência ao trabalho de parto e parto de mulheres de risco obstétrico habitual. Foram utilizados dados da pesquisa Nascer no Brasil, estudo de base hospitalar realizada em 2011/2012, com entrevistas de 23.894 mulheres. As boas práticas durante o trabalho de parto ocorreram em menos de 50% das mulheres, sendo menos frequentes nas regiões Norte, Nordeste e Centro-oeste. O uso de ocitocina e amniotomia foi de 40%, sendo maior no setor público e nas mulheres com menor escolaridade. A manobra de Kristeller, episiotomia e litotomia foram utilizada, em 37%, 56% e 92% das mulheres, respectivamente. A cesariana foi menos frequente nas usuárias do setor público, não brancas, com menor escolaridade e multíparas. Para melhorar a saúde de mães e crianças e promover a qualidade de vida, o Sistema Único de Saúde (SUS) e, sobretudo o setor privado, necessitam mudar o modelo de atenção obstétrica promovendo um cuidado baseado em evidências científicas.

Abstract
BACKGROUND Labour epidural analgesia is increasingly used as a means of pain relief for women during labour and delivery. The significant pain during labour and delivery can be terrifying for mothers-to-be and the prospect of relief from pain can help reduce fear of childbirth to an extent. However, it is not necessary that reduced fear of childbirth may lead to an increased satisfaction with the childbirth experience. AIM To determine the influence of labour epidural analgesia (LEA) on the experience of childbirth in pregnant women at a tertiary care center in southern India Materials and Methods: A pre-post interventional non-randomized study design at a tertiary care perinatal institute that used the Wijma Delivery Expectation and Experience questionnaires to determine baseline expectations of labour and childbirth and the actual experience in pregnant women. Labour analgesia was provided on maternal request or demand. Total and domain scores were compared between the two groups using non-parametric tests and a generalized linear repeated measures model after adjusting for factors that were found significant in the bivariate model. RESULTS The study included 235 pregnant women who opted for LEA and 219 pregnant women who opted against LEA. Overall, 37 (15.74%) of woman with LEA and 30 (13.70%) of women without LEA had a worse than expected experience of childbirth. Significant pain relief (p<0.001) was provided with LEA, however, the post-delivery scores did not differ significantly between the two groups (F=0.90, p=0.34) in a generalized linear repeated measures model. CONCLUSION Maternal satisfaction with the process of childbirth is a complex dynamic that is not limited to the significant relief from pain provided by LEA.

Abstract
BACKGROUND The rate of operative deliveries (both caesarean sections, vacuum extractions and forceps), continues to rise throughout the world. These are associated with significant maternal and neonatal morbidity. The most common reasons for operative births in nulliparous women are labour dystocia (failure to progress), and non-reassuring fetal status. Epidural analgesia has been shown to slow the progress of labour, as well as increase the rate of instrumental deliveries. However, it is unclear whether the use of oxytocin in women with epidural analgesia results in a reduction in operative deliveries, and thereby reduces both maternal and fetal morbidity. OBJECTIVES To determine whether augmentation of women using epidural analgesia with oxytocin will decrease the incidence of operative deliveries and thereby reduce fetal and maternal morbidity. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2013). SELECTION CRITERIA All published and unpublished randomised and quasi-randomised trials that compared augmentation with oxytocin of women in spontaneous labour with epidural analgesia versus intent to manage expectantly were included. Cluster-randomised trials were eligible for inclusion but none were identified.Cross-over study designs were unlikely to be relevant for this intervention, and we planned to exclude them if any were identified. We did not include results that were only available in published abstracts. DATA COLLECTION AND ANALYSIS The two review authors independently assessed for inclusion the 16 studies identified as a result of the search strategy. Both review authors independently assessed the risk of bias for each included study. Both review authors independently extracted data. Data were checked for accuracy. MAIN RESULTS We included two studies, involving 319 women. There was no statistically significant difference between the two groups in either of the primary outcomes of caesarean section (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.42 to 2.12) or instrumental delivery (RR 0.88, 95% CI 0.72 to 1.08). Similarly, there were no statistically significant differences between the two groups in any of the secondary outcomes for which data were available. This included Apgar score less than seven at five minutes (RR 3.06, 0.13 to 73.33), admission to neonatal intensive care unit (RR 1.07, 95% CI 0.29 to 3.93), uterine hyperstimulation (RR 1.32, 95% CI 0.97 to 1.80) and postpartum haemorrhage (RR 0.96, 95% CI 0.58, 1.59). AUTHORS' CONCLUSIONS There was no statistically significant difference identified between women in spontaneous labour with epidural analgesia who were augmented with oxytocin, compared with those who received placebo. However, due to the limited number of women included in the studies, further research in the form of randomised controlled trials are required.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. METHOD Between July 2009 and December 2010, 188 nulliparous women with a singleton pregnancy at term were enrolled and only one dropped. The participants were randomized to receive either standard care (control group, n = 91) or uterine fundal pressure by the Labor Assister (Baidy M-520/Curexo, Inc., Seoul, Korea; active group, n = 97) during the second stage of labor in addition to standard care. The Labor Assister is an inflatable obstetric belt that is synchronized to apply constant fundal pressure during a uterine contraction. The primary endpoint was duration of the second stage of labor in women who delivered vaginally (control, n = 80 versus active, n = 93). It was not analyzed in women who delivered by cesarean section (n = 14) and delivered precipitously (n = 1). The secondary outcomes are perinatal outcomes and perineal laceration. Participants received patient-controlled epidural analgesia. RESULTS The 93 women in the active group spent less time in the second stage of labor when compared to the 80 women in the control group (46.51 ± 28.01 min versus 75.02 ± 37.48 min, p < 0.001). There was no significant difference in perinatal outcomes and perineal laceration between the two groups. CONCLUSION The uterine fundal pressure exerted by the inflatable obstetric belt reduces the duration of the second stage of labor without complications in nulliparous women who receive patient-controlled epidural analgesia.

Abstract
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, respectively, 78.2% and 76.4% in the intervention group and the control group without significant difference (P = .748). Rates of instrumental and cesarean section deliveries were not significantly different between intervention and control groups (18.2% vs. 19.1%, P = .89, and 19.1% vs. 17.3%, P = .73, respectively). In intervention and control groups, persistent OP position rates were significantly higher among women who had cesarean section (71.4% and 89.5%, respectively) and an instrumental delivery (25% and 33.3%, respectively) than among women who achieved spontaneous vaginal birth (5.8% and 2.8%, respectively). In multivariable analysis, body mass index and parity were found to have significant and independent impact on the probability of fetal head rotation. CONCLUSION Our study failed to demonstrate any maternal or neonatal benefit to a policy of maternal posturing for the management of OP position during labor.

Abstract
OBJECTIVE Analgesia for labor is a legal obligation in Chile. In our institution we implemented patient controlled analgesia for pain relief during labor. We describe the perception of the several professionals involved in the medical care of patients in labor in terms of effectiveness, usefulness, satisfaction, and safety. MATERIAL AND METHODS A self-reported questionnaire was given to the professionals involved, and the obstetrical and neonatal outcomes were recorded along with the workload indices. Twenty-five structured questions were presented with a Likert type score to evaluate analgesia quality, workload of professionals involved, adverse effects, patient satisfaction, and healthcare workers satisfaction. Finally, a question was asked about the overall perception. RESULTS We found that the overall perception of the analgesic technique was (mean) 6.0 (SD) (0.88). A decrease in the anesthesiologist workload was observed, without affecting obstetric outcomes. CONCLUSION Considering the study design limitations, absence of knowledge of economical impact, and the satisfaction level of patients under standard epidural analgesia, we recommend the patient controlled analgesia technique due to its good obstetric outcomes, general satisfaction and workload decrease.

Abstract
BACKGROUND Epidural analgesia is claimed to result in prolonged labor. Previous studies have assessed epidural analgesia vs systemic opioids rather than to parturients receiving no analgesia. This study aimed to evaluate the effect of epidural analgesia on labor duration compared with parturients devoid of analgesia. METHODS One hundred sixty nulliparous women in spontaneous labor at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group, whereas those not enthusiastic to labor analgesia were allocated in the control group. Epidural analgesia was provided with 20 mL bolus 0.5% epidural lidocaine plus fentanyl and maintained at 10 mL for 1 h. Duration of the first and second stages of labor, number of parturients receiving oxytocin, maximal oxytocin dose required for each parturient, numbers of instrumental vaginal, vacuum-assisted, and cesarean deliveries and neonatal Apgar score were recorded. RESULTS There was no statistical difference in the duration of the active-first and the second stages of labor, instrumental delivery, vacuum-assisted or cesarean delivery rates, the number of newborns with 1-min and 5-min Apgar scores less than 7 between both groups and number of parturients receiving oxytocin, however, the maximal oxytocin dose was significantly higher in the epidural group. CONCLUSION Epidural analgesia by lidocaine (0.5%) and fentanyl does not prolong labor compared with parturients without analgesia; however, significant oxytocin augmentation is required during the epidural analgesia to keep up the aforementioned average labor duration.
