Early versus delayed amniotomy during labor induction with oxytocin in women with Bishop’s score of ≥6: a randomized trial

Objective: To study the effect of “early amniotomy” {initiating induction of labor (IOL) with amniotomy followed by oxytocin} versus “late amniotomy” (initiating IOL with oxytocin followed by amniotomy 4–8?h later) in induced labor.

Methods and Materials: One hundred and fifty women with Bishop’s score of ≥6 undergoing IOL were randomized into “early amniotomy” and “delayed amniotomy”.

Results: Early amniotomy resulted in a reduced induction-delivery interval (IDI) (7.35 versus 11.66?h with delayed amniotomy, p?=?.000) but higher the caesarean section (CS) rate was observed (10.7 versus 2.7% with delayed amniotomy, p?=?.049). With early amniotomy, the proportion of women delivering within 12?h was higher (86.7 versus 60%, p?=?.000) and the maximum oxytocin concentration used was lower (30.05 versus 39.68?mU/min, p?=?.001) as compared to delayed amniotomy. The neonatal outcomes were similar in the two groups. Early amniotomy detected meconium prior to initiating uterine contractions with oxytocin in three women who underwent CS for meconium.

Conclusion: Initiating IOL with amniotomy in women with a favorable cervix was efficacious in expediting delivery, but it resulted in a higher CS rate. The higher CS rate was partly due to CS for meconium detected as a result of early amniotomy.

Factors Associated with the Choice of Delivery without Epidural Analgesia in Women at Low Risk in France

ABSTRACT: Background: Regional anesthesia is used for three‐fourths of the deliveries in France. Epidural analgesia during labor is supposed to be available to all women at low risk. The purpose of our study was to examine how the choice of delivery without an epidural varied in this context according to women’s characteristics, prenatal care, and type of maternity unit. Methods: The 2003 National Perinatal Survey in France collected data about a representative sample of births. We selected 8,233 women who were at low risk and therefore should have been able to choose whether or not to deliver without epidural analgesia. Women were interviewed in the maternity unit after delivery. The factors associated with women’s choice to deliver without epidural analgesia were studied with multivariable analyses. Results: Of the 2,720 women who gave birth without epidural analgesia, 37 percent reported that they had not wanted one; other reasons were labor occurring too quickly (43.9%), medical contraindication (3.3%), and unavailability of an anesthesiologist (2.8%). The reported decision to deliver without epidural analgesia was closely associated with high parity. It was also more frequent among women in an unfavorable social situation (not cohabiting, no or low‐qualified job) and among women who gave birth in nonuniversity public hospitals, in small‐ or medium‐sized maternity units, and in maternity units without an anesthesiologist always on site. Conclusions: Unfavorable social situation and organizational factors are associated with the reported choice to give birth without epidural analgesia. This finding suggests that women are not always in a position to make a real choice. It would be useful to improve the understanding of how pregnant women define their preferences and to know how these preferences change during pregnancy and labor. (BIRTH 35:3 September 2008)     

Update on best available options in obstetrics anaesthesia: perinatal outcomes,side effects and maternal satisfaction. Fifteen years systematic literature review

Purpose

In modern obstetrics, different pharmacological and non-pharmacological options allow to obtain pain relief during labour, one of the most important goals in women satisfaction about medical care. The aim of this review is to compare all the analgesia administration schemes in terms of effectiveness in pain relief, length of labour, mode of delivery, side effects and neonatal outcomes.

Methods

A systematic literature search was conducted in electronic databases in the interval time between January 1999 and March 2013. Key search terms included: “labour analgesia”, “epidural anaesthesia during labour” (excluding anaesthesia for Caesarean section), “epidural analgesia and labour outcome” and “intra-thecal analgesia”.

Results

10,331 patients were analysed: 5,578 patients underwent Epidural-Analgesia, 259 patients spinal analgesia, 2,724 combined spinal epidural analgesia, 322 continuous epidural infusion (CEI), 168 intermittent epidural bolus, 684 patient-controlled infusion epidural analgesia and 152 intra-venous patient-controlled epidural analgesia. We also considered 341 women who underwent patient-controlled infusion epidural analgesia in association with CEI and 103 patients who underwent patient-controlled infusion epidural analgesia in association with automatic mandatory bolus.

Conclusion

No significant differences occurred among all the available administration schemes of neuraxial analgesia. In absence of obstetrical contraindication, neuraxial analgesia has to be considered as the gold standard in obtaining maternal pain relief during labour. The options available in the administration of analgesia should be known and evaluated together by both gynaecologists and anaesthesiologists to choose the best personalized scheme and obtain the best women satisfaction. Since it is difficult to identify comparable circumstances during labour, it is complicate to standardize drugs schemes and their combinations.     

Repeat Cesarean Delivery: What Indications Are Recorded in the Medical Chart?

Abstract: Background: National surveillance estimates reported a troubling 63 percent decline in the rate of vaginal birth after cesarean delivery (VBAC) from 1996 (28.3%) to 2003 (10.6%), with subsequent rising rates of repeat cesarean delivery. The study objective was to examine patterns of documented indications for repeat cesarean delivery in women with and without labor. Methods: We conducted a population‐based validation study of 19 nonfederal short‐stay hospitals in Washington state. Of the 4,541 women who had live births in 2000, 11 percent (n = 493) had repeat cesarean without labor and 3 percent (n = 138) had repeat cesarean with labor. Incidence of medical conditions and pregnancy complications, patterns of documented indications for repeat cesarean delivery, and perioperative complications in relation to repeat cesarean delivery with and without labor were calculated. Results: Of the 493 women who underwent a repeat cesarean delivery without labor, “elective”(36%) and “maternal request”(18%) were the most common indications. Indications for maternal medical conditions (3.0%) were uncommon. Among the 138 women with repeat cesarean delivery with labor, 60.1 percent had failure to progress, 24.6 percent a non‐reassuring fetal heart rate, 8.0 percent cephalopelvic disproportion, and 7.2 percent maternal request during labor. Fetal indications were less common (5.8%). Breech, failed vacuum, abruptio placentae, maternal complications, and failed forceps were all indicated less than 5.0 percent. Women's perioperative complications did not vary significantly between women without and with labor. Regardless of a woman's labor status, nearly 10 percent of women with repeat cesarean delivery had no documented indication as to why a cesarean delivery was performed. Conclusions: “Elective” and “maternal request” were common indications among women undergoing repeat cesarean delivery without labor, and nearly 10 percent of women had undocumented indications for repeat cesarean delivery in their medical record. Improvements in standardization of indication nomenclature and documentation of indication are especially important for understanding falling VBAC rates. Future research should examine how clinicians and women anticipate, discuss, and make decisions about childbirth after a previous cesarean delivery within the context of actual antepartum care.

Epidural Analgesia Use as a Marker for Physician Approach to Birth: Implications for Maternal and Newborn Outcomes

Background: Understanding the association between caregiver belief systems and practice patterns is an emerging area of research. We hypothesized an association between a maternity caregiver's belief system and his or her behavior. The study objective was to determine if a family physician's overall approach to maternity care, as measured by average use of epidural analgesia, was associated with maternal and fetal outcomes. Methods: Retrospective analysis was conducted of the births of three cohorts of 1992 nulliparous, low‐risk women attended by 96 family physicians within an 18‐month period in the department of family practice at the largest maternity hospital in Canada. Cohorts were based on the physicians' mean use of epidural analgesia for the women. Family physicians attending fewer than 5 births were excluded. The main outcome measures, by physician epidural utilization cohort, were maternal/newborn morbidity, procedure rates, consultation rates, and length of stay. Results: Family physicians were separated into cohorts based on their mean use of epidural analgesia at rates of: low, 0–30 percent (15 physicians, 263 births); medium, 31–50 percent (55 physicians, 1323 births); and high, 51–100 percent (26 physicians, 406 births). After adjustment for maternal age and race, patients of low versus high epidural users were admitted at a later state of cervical dilation (mean 4.0 vs 3.1 cm), received less electronic fetal monitoring (76.4 vs 87.2%) and oxytocin augmentation (12.2 vs 29.8%), sustained fewer malpositions (occiput posterior or transverse)(23.2 vs 34.2%), had fewer cesarean sections (14.0 vs 24.4%), less obstetric consultation (47.9 vs 63.8%), and fewer newborn special care admissions (7.2 vs 12.8%). Conclusions: In our setting, high use of epidural analgesia is a marker for a style of practice characterized by malpositions leading to dysfunctional labors and higher intervention rates leading, in turn, to excess maternal/newborn morbidity.     

Older Maternal Age and Intervention in Labor: A Population‐Based Study Comparing Older and Younger First‐Time Mothers in Victoria,Australia

Background: In Australia, birth rates for women aged 35 years or more are significant and increasing and a considerable percentage are first births. This study investigated the effect of maternal age on interventions in labor and birth for primiparous women aged 35 to 44 years compared with primiparous women aged 25 to 29 years. Methods: All primiparous women who gave birth in Victoria, Australia, in 2005 and 2006 (n = 57,426) were included in this population‐based cross‐sectional study. Women were stratified by admission status (private/public). Main outcome measures were induction of labor, augmentation of labor, use of epidural analgesia, and method of birth. Multivariate logistic regression was used to explore the relationship between maternal age and cesarean adjusted for confounders. Results: Older women were more likely to give birth by cesarean section whether admitted as public or private patients. For private patients, total cesarean rates were 31.8 percent (25–29 yr), 46.0 percent (35–39 yr), and 60.0 percent (40–44 yr; p < 0.001) compared with 27.5, 41.6, and 53.4 percent for public patients (p < 0.001). Older women who experienced labor were more likely to have an instrumental vaginal birth or an emergency cesarean section than younger women. Both were more common in women admitted as private patients. Age‐related trends were also seen for induction of labor and use of epidural analgesia. Rates were higher for private patients. Rates of induction were (37.8, 40.2, and 42.5%) for private patients compared with (32.1, 36.7, and 40.1%) for public patients and rates for epidural were (45.3, 49.9, and 48.1%) among private patients compared with (33.3, 38.8, and 39.3%) among public patients. Conclusions: Interventions in labor and birth increased with maternal age, and this effect was seen particularly for cesarean section among women admitted privately. These findings were not fully explained by the complications we considered. (BIRTH 38:1 March 2011)     

Effects of combined spinal–epidural analgesia on first stage of labor: a cohort study

Background: Neuraxial anesthesia is considered as the gold standard in the control labor of pain. Its variants are epidural analgesia and combined spinal–epidural analgesia. Few studies, as yet, have investigated the duration of labor as a primary outcome. Some authors have suggested that combined spinal–epidural analgesia may reduce labor duration but at the moment the benefit of shortening labor is uncertain. The main aim of this study was to compare combined spinal–epidural with epidural analgesia in terms of their effect on duration of stage I labor, maternal, and neonatal outcomes.

Methods: A prospective cohort study was conducted. Parturients who requested analgesia at cervical dilatation <6?cm were included. Analgesia was either epidural with low concentration levobupivacaine or combined spinal epidural with subarachnoid sufentanil. The primary outcome was the length of stage I labor. Onset and quality of analgesia, mode of delivery, effects on uterine activity and use of oxytocin, fetal heart rate abnormalities and uterine hyperkinesia, maternal, and neonatal complications were also considered.

Results: We enrolled 400 patients: 176 in the combined spinal–epidural group and 224 in the epidural group. Patients in the two treatment groups were similar with regard to demographic characteristics, parity, and incidence of obstetric comorbidities, labor induction, oxytocin infusion, Bishop score, and Visual Analogue Score (VAS) at analgesia request. Duration of stage I labor did not differ, at 195 (120–300) minutes for both the groups (p?=?.7). Combined spinal–epidural was associated with less reduction in uterine contractility after initial administration: 15.34 versus 39.73%, (p?p?=?.002). Onset of analgesia was quicker for combined spinal–epidural analgesia: 31 versus 20%, with VAS <4 after 5?minutes, (p?Conclusions: Combined spinal–epidural with subarachnoid sufentanil may not reduce the duration of stage I labor, but in our study it appeared to affect uterine contractility less. It also had a more rapid onset and was more effective, without any concomitant increase in maternal or neonatal complications.     

Attitudes of the New Generation of Canadian Obstetricians: How Do They Differ from Their Predecessors?

Background: Attitudes drive practice, perhaps more than evidence . The objective of this study was to determine if the new generation of Canadian obstetricians has attitudes differing from those of their predecessors. Methods: Employing a cross‐sectional, Internet, and paper‐based survey, we conducted an in‐depth study of obstetricians responding to the Canadian National Maternity Care Attitudes Survey. Results: Of the 800 Canadian obstetricians providing intrapartum care, 549 (68.6%) responded. Participants were stratified by age less than or equal to 40 years compared with those over 40 years; 81 percent of those 40 years or younger were women versus 40 percent over 40 years of age. Younger obstetricians were significantly more likely to favor use of routine epidural analgesia and believed that it did not interfere with labor or lead to instrumentation; were more concerned and feared the perineal and pelvic floor consequences of vaginal birth compared with cesarean section; and were significantly less supportive of vaginal birth after prior cesarean section, home birth, birth plans, routine episiotomy, and routine electronic fetal monitoring as providing maternal or fetal benefits. They were less positive than the older generation about a range of approaches to reducing the cesarean section rate, the importance of maternal choice and role in their own birth, and peer review, and they were more likely to believe that women having a cesarean section were not missing an important experience. No significant generational differences were found for ambivalent attitudes to vaginal breech birth. Conclusions: Younger obstetricians were more evidence‐based for some issues and less for others. In general younger obstetricians were more supportive of the role of birth technology in normal birth, including routine epidural analgesia, and they were less appreciative of the role of women in their own birth. They saw cesarean section as a solution to many perceived labor and birth problems. Results suggest a need to examine how obstetricians acquire their favorable attitudes to birth technology in normal birth. (BIRTH 38:2 June 2011)     

A Randomized,Controlled Trial of Nurse-Midwifery Care

ABSTRACT: Background : In 1990 a pilot nurse-midwifery program was implemented in a tertiary care hospital in a major western Canadian city. A randomized, controlled trial was conducted to determine if when maternal and newborn patient outcomes were compared, the midwifery program was as effective as traditional, low-risk health care available in the city. Methods : All low-risk women who requested and qualified for nurse-midwifery care were randomly assigned to an experimental or control group. Results : One hundred one women received care from nurse-midwives and 93 received standard care from either an obstetrician or family physician. The rate of cesarean delivery in the nurse-midwife group was 4 percent compared with 15.1 percent in the physician group. The episiotomy rate, excluding cesarean deliveries, for the nurse-midwife group was 15.5percent compared with 32.9 percent in the physician group. The rates of epidural anesthesia for pain relief in labor were 12.9 percent and 23.7 percent, respectively. Statistically significant differences were found for ultrasound examinations, amniotomy, intravenous drug administration during labor; dietary supplements, length of hospital stay, and admission of infants to the neonatal intensive care unit. Conclusions : The results clearly support the effectiveness of the pilot nurse-midwifery program and suggest that more extensive participation of midwives in the Canadian health care system is an appropriate use of health care dollars.     

Nulliparas' Preferences for Epidural Analgesia: Their Effects on Actual Use in Labor

Background: Few studies have directly examined the reasons for choices of pain relief during labor. The purpose of this study was to investigate if women's preferences for epidural analgesia in labor have an impact on the use of intrapartum epidural analgesia. Methods: Nulliparous women attending childbirth classes completed questionnaires about their antenatal preferences for the use of intrapartum epidural analgesia. Data on actual use of analgesia was obtained by chart review. The analysis included 303 women with either spontaneous or induced labor at term. Results: The 185 women who planned to receive epidural analgesia had a markedly higher rate of epidural use (91%) than the 110 women who hoped to avoid it (57%) ( p= 0.001). Of 237 epidurals administered, 169 (71%) were planned during the antenatal period. Among women receiving epidural analgesia, those planning to receive it tended to have more frequent early administration (≤ 3 cm cervical dilation) than women who unsuccessfully tried to avoid epidural use (54% vs. 24%, p= 0.003). Conclusion: In our population of nulliparas, a woman's antenatal plan to receive epidural analgesia is strongly associated with her likelihood of receiving it. Women who plan to receive epidural analgesia have earlier administration.     

Continuity of Nursing Care and Its Link to Cesarean Birth Rate

ABSTRACT: Background: High cesarean birth rates are an international concern. The role of patterns of nursing care responsibility in preventing or contributing to cesarean births has been understudied. Our study sought to identify and describe indicators of continuity of nursing care responsibility during labor and to explore whether any association between these indicators and risk of cesarean birth could be identified empirically using an existing data set. Methods: We obtained a representative sample of low‐risk women giving birth in an intrapartum unit at a university hospital in Quebec, Canada, with approximately 3,700 births per year. To be considered for inclusion, women needed to have been primiparous, carrying singletons in vertex position, and at 37 weeks’ gestation or more. All women giving birth over a 13‐month period were assessed for eligibility using the hospital’s birth log. Data were extracted from the medical records of every second eligible birth, including information related to patterns of nursing care responsibility, maternal and infant characteristics, obstetric procedures, non–health‐related risk factors, and type of birth. Results: Data on all variables of interest were available for 467 women. These women were cared for by 1–17 nurses, care responsibility changed hands for them from 1 to 28 times, and the mean length of labor for which the same nurse was responsible for a woman ranged from 10 to 1,045 minutes. After controlling for length of labor, maternal age, maternal height, infant weight, gestational age, induction, type of rupture, and epidural analgesia, the odds ratio for cesarean birth due to number of nurses was 1.17 (95% CI 1.04, 1.32); 1 or more nurses switch per 2 hours (i.e., number of times care responsibilities changed hands), 1.04 (95% CI 0.62, 1.74); and 33 percent or more of the labor attended by the same nurse, 0.74 (95% CI 0.42, 1.30). Conclusions: An association was observed between number of nurses caring for a laboring woman and risk of cesarean delivery. Estimates of the association of other patterns of nursing care responsibility on cesarean birth were not sufficiently precise to draw conclusions. (BIRTH 34:1 March 2007)     

Team Midwifery Care in a Tertiary Level Obstetric Service: A Randomized Controlled Trial

Background: In 1996 a new model of maternity care characterized by continuity of midwifery care from early pregnancy through to the postpartum period was implemented for women attending Monash Medical Centre, a tertiary level obstetric service, in Melbourne, Australia. The objective of this study was to compare the new model of care with standard maternity care. Methods: In a randomized controlled trial, 1000 women who booked at the antenatal clinic and met the eligibility criteria were randomly allocated to receive continuity of midwifery care (team care) from a group of seven midwives in collaboration with obstetric staff, or care from a variety of midwives and obstetric staff (standard care). The primary outcome measures were procedures in labor, maternal outcomes, neonatal outcomes, and length of hospital stay. Results: Women assigned to the team care group experienced less augmentation of labor, less electronic fetal monitoring, less use of narcotic and epidural analgesia, and fewer episiotomies but more unsutured tears. Team care women stayed in hospital 7 hours less than women in standard care. More babies of standard care mothers were admitted to the special care nurseries for more than 5 days because of preterm birth, and more babies of team care mothers were admitted to the nurseries for more than 5 days with intrauterine growth retardation. No differences occurred in perinatal mortality between the two groups. Conclusions: Continuity of midwifery care was associated with a reduction in medical procedures in labor and a shorter length of stay without compromising maternal and perinatal safety. Continuity of midwifery care is realistically achievable in a tertiary obstetric referral service.     

A Randomized Controlled Trial of Continuous Labor Support for Middle‐Class Couples: Effect on Cesarean Delivery Rates

ABSTRACT: Background: Previous randomized controlled studies in several different settings demonstrated the positive effects of continuous labor support by an experienced woman (doula) for low‐income women laboring without the support of family members. The objective of this randomized controlled trial was to examine the perinatal effects of doula support for nulliparous middle‐income women accompanied by a male partner during labor and delivery. Methods: Nulliparous women in the third trimester of an uncomplicated pregnancy were enrolled at childbirth education classes in Cleveland, Ohio, from 1988 through 1992. Of the 686 prenatal women recruited, 420 met enrollment criteria and completed the intervention. For the 224 women randomly assigned to the experimental group, a doula arrived shortly after hospital admission and remained throughout labor and delivery. Doula support included close physical proximity, touch, and eye contact with the laboring woman, and teaching, reassurance, and encouragement of the woman and her male partner. Results: The doula group had a significantly lower cesarean delivery rate than the control group (13.4% vs 25.0%, p = 0.002), and fewer women in the doula group received epidural analgesia (64.7% vs 76.0%, p = 0.008). Among women with induced labor, those supported by a doula had a lower rate of cesarean delivery than those in the control group (12.5% vs 58.8%, p = 0.007). On questionnaires the day after delivery, 100 percent of couples with doula support rated their experience with the doula positively. Conclusions: For middle‐class women laboring with the support of their male partner, the continuous presence of a doula during labor significantly decreased the likelihood of cesarean delivery and reduced the need for epidural analgesia. Women and their male partners were unequivocal in their positive opinions about laboring with the support of a doula. (BIRTH 35:2 June 2008)     

Outcomes of induced versus spontaneous labor

Purpose: Induced labor is associated with a higher request for analgesia than spontaneous labor. This study compared duration of labor, mode of delivery, quantity of blood loss, type of perineal outcome and neonatal outcomes between women in induced labor and women in spontaneous labor, both on epidural analgesia (administered at cervical dilation ≤?4?cm).

Methods: In a two-year longitudinal cohort study, data were gathered from nulliparous women with a single cephalic pregnancy of at least 37 weeks attending the labor and delivery ward in Policlinico San Matteo Fundation-Pavia. Data were compared for women with early labor analgesia in (1) spontaneous labor (Robson group 1) and (2) induced labor (dinoprostone – vaginal insert or gel, Robson group 2a).

Results: Of the 1104 women who underwent epidural analgesia in the study period, 531 were included: 326 in spontaneous labor and 205 in induced labor. The only significant difference found was duration of the first stage, which lasted 305 (200–390) min in spontaneous labor compared to 205?min (120–345) in induced labor (p <0.001).

Conclusions: In women on early epidural analgesia, induction is associated with a shorter duration of the first stage of labor and does not affect other outcomes.     

Analgesia epidural a demanda. Estudio de las consecuencias sobre el parto

ObjectiveTo study the effect of on-patient-request epidural analgesia in a hospital of InsaludMaterial And Method207 nuliparas with unique fetus at term who gave birth in 1997 and 198 that did it in 1999–2000. Groups compare themselves both to each other and separately the childbirths with epidural analgesia of both groupsResultsWe have not observed changes in the frequency of operative deliveries or on neonatal morbidity. There were differences in duration of labor, more use of oxytocin and maternal fever in the group of on-patient-request epidural analgesia. At the time of restricted use, the epidural analgesia was associated to prolonged labor, higher doses of oxytocin and greater use of fentanil. When using this analgesia on-request we have observed a prolongation of the second stage of labor and a greater number of women receiving oxytocinConclusionsWe have not found the epidural analgesia is associated to important adverse effects on the evolution of childbirth, heightening the benefits of this technique     

Neuraxial analgesia versus intravenous remifentanil for pain relief in early labor in nulliparous women

Objective

To assess if there is a difference in duration of labor, the mode of delivery, average Visual Analog Scale (VAS) pain scores, maternal overall satisfaction with analgesia, side effects and neonatal outcomes in nulliparous women who received early labor analgesia with either epidural, patient-controlled IV analgesia (PCIA) with remifentanil or combined spinal–epidural (CSE) techniques.

Study design

This is a prospective randomized interventional study.

Subjects and methods

The study included 1,140 healthy nulliparous women (with term, singleton pregnancies) early in labor, requesting labor analgesia, during the period from September 2009 to August 2011 at TAIBA Hospital in Kuwait. The participants were randomized to receive either epidural analgesia (Group I), or PCIA with remifentanil (Group II) or CSE analgesia (Group III). The primary outcome was the rate of cesarean delivery.

Results

CSE analgesia was associated with a statistically highly significant decrease in labor duration (from analgesia to vaginal delivery), duration of latent and active phases of the first stage, and duration of the second stage of labor, average VAS pain scores, and a highest maternal overall satisfaction score with analgesia (P?<?0.01) as compared to epidural analgesia or PCIA with remifentanil.

Conclusion

In terms of labor duration, average VAS pain scores, and maternal overall satisfaction score with analgesia, CSE analgesia is superior to that provided by epidural analgesia or PCIA with remifentanil for pain relief in early labor in nulliparous women. However, there were no differences in the mode of delivery, side effects or neonatal outcomes between the three techniques.     

Prolonged second stage in nulliparous with epidurals: a systematic review

Objective: Management of prolonged second stage of labor remains a clinical challenge. Nulliparous with epidurals are the most likely women to have a prolonged second stage and can be difficult to manage. The aim of this study was to evaluate the maternal and fetal morbidities associated with prolonged second stage of labor in nulliparous women with epidurals.

Methods: A systematic review of the literature was performed using PubMed, Ovid and Scopus searches for case series evaluating the morbidities of prolonged second stage of labor. Search terms used were “prolonged”, “second stage”, and “labor”. Prolonged second stage was defined as three hours or more. Retrospective case series of prolonged second stage in nulliparous women with epidurals were identified. The primary outcome was the incidence of cesarean delivery.

Results: Two retrospective series with 5350 nulliparous women with prolonged second stage were identified. 76.3% (4 081/5 350) had an epidural. Of all nulliparous women with an epidural, 11.5% (4 081/35 469) had prolonged second stage. Cesarean Delivery occurred in 19.8% of these cases (782/4 081), while 80.2% had a vaginal delivery.

Conclusions: Over three quarters of nulliparous women with epidural diagnosed with a prolonged second stage deliver vaginally.     

Have Women Become More Willing to Accept Obstetric Interventions and Does This Relate to Mode of Birth? Data from a Prospective Study

ABSTRACT: Background: Concern has increased about rising rates of cesarean section and other obstetric interventions, and it has been suggested that a change in women’s attitudes may be partly responsible. Our objectives were, first, to examine changes in women’s antenatal willingness to accept obstetric interventions between 1987 and 2000 and, second, to look at the relationship between willingness to accept obstetric interventions and mode of birth. Methods: Data on willingness to accept obstetric interventions were collected at 35–36 weeks of pregnancy using postal questionnaires, and follow‐up of women was conducted 6 weeks postnatally. Data are presented for 977 women drawn from 8 maternity units in England who were due to give birth in April to May 2000. To address the first objective, data were compared with the parent study carried out in 1987. Results: The sample had significantly more positive antenatal attitudes toward obstetric interventions than the comparable sample in 1987 (F= 42.25, df= 1, p < 0.001). Willingness to accept obstetric interventions was related to mode of birth. Binary logistic regression controlling for age, education, and parity showed that women with high “willingness to accept intervention” scores had a nearly twofold increase in the odds of an operative or instrumental birth (OR 1.94, 95% CI 1.28–2.95) compared with women who had low scores. These attitudes also predicted epidural analgesia use, and differences in mode of birth were no longer significant when epidural use was included in the regression model. Conclusions: A shift toward greater willingness to accept obstetric interventions appears to have occurred since 1987, and this shift does appear to relate to mode of birth in the 2000 cohort but not in 1987. The findings suggest that epidural analgesia use mediates the link. (BIRTH 34:1 March 2007)     

Institutional Processes and Individual Responses: Women’s Experiences of Care in Relation to Cesarean Birth

Abstract: Background: Cesarean section is an increasingly common mode of birth, and although clinical care has improved and the risks reduced, less attention has been paid to the effect of the procedure and the care received. The aim of this study was to gain a better understanding by investigating individual women’s recent experiences and reflections on their care. Methods: Views of women who had recently undergone cesarean birth were obtained in a study in which a random sample of women was selected by means of birth registrations in England and invited to complete a questionnaire 3 months after the birth. Text responses to open‐ended questions about care during labor and birth, the postnatal period in hospital, and anything else women wished to say about their maternity care were analyzed using qualitative methods. Results: A response rate of 63 percent was achieved; 23 percent of women (n = 682) had a cesarean section birth, 53 percent of which were because of unforeseen problems in labor. A total of 66 percent of women who had a cesarean section responded to one or more open questions. Anticipated themes that were confirmed related to expectations, uncertainty, emotional reactions, pain and discomfort, explanations, support, and adjustment. Emerging themes included “being heard,”“how it might have been different,”“wasted effort,”“just another mother,”“wounds and hurt feelings,” and “needing to talk.” Conclusions: Women responded as individuals and despite different clinical circumstances, the role of the staff and the institutions in which care was provided were key factors in the way most women constructed their cesarean section experience. The themes described present a powerful argument and reminder about why health professionals working in maternity care need to continue to listen to women. (BIRTH 37:2 June 2010)
