Johnson K, Johansson K, Elvander C, Saltvedt S, Edqvist M. Variations in the use of oxytocin for augmentation of labour in Sweden: a population-based cohort study. Sci Rep 2024; 14:17483. [PMID: 39080360 PMCID: PMC11289380 DOI: 10.1038/s41598-024-68517-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Accepted: 07/24/2024] [Indexed: 08/02/2024] Open
Abstract
National Swedish data shows substantial variation in the use of oxytocin for augmentation of spontaneous labour between obstetric units. This study aimed to investigate if variations in the use of oxytocin augmentation are associated with maternal and infant characteristics or clinical factors. We used a cohort design including women allocated to Robson group 1 (nulliparous women, gestational week ≥ 37 + 0, with singleton births in cephalic presentation and spontaneous onset of labour) and 3 (parous women, gestational week ≥ 37 + 0, with singleton births in cephalic presentation, spontaneous onset of labour, and no previous caesarean birth). Crude and adjusted logistic regression models with marginal standardisation were used to estimate risk ratios (RR) and risk differences (RD) with 95% confidence intervals (CI) for oxytocin use by obstetric unit. An interaction analysis was performed to investigate the potential modifying effect of epidural. The use of oxytocin varied between 47 and 73% in Robson group 1, and 10% and 33% in Robson group 3. Compared to the remainder of Sweden, the risk of oxytocin augmentation ranged from 13% lower (RD - 13.0, 95% CI - 15.5 to - 10.6) to 14% higher (RD 14.0, 95% CI 12.3-15.8) in Robson group 1, and from 6% lower (RD - 5.6, 95% CI - 6.8 to - 4.5) to 18% higher (RD 17.9, 95% CI 16.5-19.4) in Robson group 3. The most notable differences in risk estimates were observed among women in Robson group 3 with epidural. In conclusion, variations in oxytocin use remained despite adjusting for risk factors. This indicates unjustified differences in use of oxytocin in clinical practice.

Weckend M, McCullough K, Duffield C, Bayes S, Davison C. Failure to progress or just normal? A constructivist grounded theory of physiological plateaus during childbirth. Women Birth 2024; 37:229-239. [PMID: 37867094 DOI: 10.1016/j.wombi.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 10/08/2023] [Accepted: 10/09/2023] [Indexed: 10/24/2023]
Abstract
BACKGROUND AND PROBLEM During childbirth, one of the most common diagnoses of pathology is 'failure to progress', frequently resulting in labour augmentation and intervention cascades. However, failure to progress is poorly defined and evidence suggests that some instances of slowing, stalling and pausing labour patterns may represent physiological plateaus. AIM To explore how midwives conceptualise physiological plateaus and the significance such plateaus may have for women's labour trajectory and birth outcome. METHODS Twenty midwives across Australia participated in semi-structured interviews between September 2020 and February 2022. Constructivist grounded theory methodology was applied to analyse data, including multi-phasic coding and application of constant comparative methods, resulting in a novel theory of physiological plateaus that is firmly supported by participant data. FINDINGS This study found that the conceptualisation of plateauing labour depends largely on health professionals' philosophical assumptions around childbirth. While the Medical Dominant Paradigm frames plateaus as invariably pathological, the Holistic Midwifery Paradigm acknowledges plateaus as a common and valuable element of labour that serves a self-regulatory purpose and results in good birth outcomes for mother and baby. DISCUSSION Contemporary medicalised approaches in maternity care, which are based on an expectation of continuous labour progress, appear to carry a risk for a misinterpretation of physiological plateaus as pathological. CONCLUSION This study challenges the widespread bio-medical conceptualisation of plateauing labour as failure to progress, encourages a renegotiation of what can be considered healthy and normal during childbirth, and provides a stimulus to acknowledge the significance of childbirth philosophy for maternity care practice.

Abstract
BACKGROUND There is widespread concern around the rising rates of cesarean births (CBs), especially among first-time mothers, despite evidence suggesting increased morbidities after birth by cesarean. There are uncertainties around factors associated with rising rates of CBs among first-time mothers in Ireland, and insight into these is essential for understanding the rising trend in CBs. Therefore, this study aimed to identify the factors associated with CBs in nulliparous women. METHODS A prospective cohort study was conducted in three maternity hospitals in the Republic of Ireland between 2012 and 2017. Data were collected from 3047 nulliparous women using self-administered surveys antenatally and at 3 months postpartum and from consenting women's hospital records (n = 2755) and analyzed using the Poisson regression to assess associations between demographic and clinical factors and the main outcome measures, planned and unplanned CBs. RESULTS Common risk factors for planned and unplanned CBs were being aged ≥40 years, being in private care, multiple pregnancy, and fetus in breech or other malpresentations. An unplanned CB occurred for 22.43% (n = 377/1681) of women who did not have induction of labor (IOL) or who had IOL with no epidural, but the risk was about twice as high for women who had IOL and epidural. CONCLUSIONS Findings confirm multifactorial reasons for CB and the challenge of reversing the increasing CB rate if maternal age, overweight/obesity, infertility treatment, multiple pregnancy, and preexisting hypertension in Ireland continue to increase. There is a need to address prelabor interventions, especially IOL combined with epidural analgesia with respect to unplanned CB.

Peripartum outcomes after combined myo-inositol, probiotics, and micronutrient supplementation from preconception: the NiPPeR randomized controlled trial. Am J Obstet Gynecol MFM 2022; 4:100714.

Abstract
BACKGROUND Evidence that nutritional supplementation before and during pregnancy improves peripartum outcomes is sparse. In the Nutritional Intervention Preconception and During Pregnancy to Maintain Healthy Glucose Metabolism and Offspring Health (NiPPeR) trial, we previously reported that a combined myo-inositol, probiotics, and micronutrient supplement started at preconception showed no difference in the primary outcome of gestational glycemia, but did reduce the risk of preterm delivery, preterm prelabor rupture of membranes, and major postpartum hemorrhage. OBJECTIVE This study aimed to examine the hypothesis that a reduction in major postpartum hemorrhage following a combined nutritional (myo-inositol, probiotics, and micronutrients) intervention is linked with promotion of labor progress and reduced operative delivery. STUDY DESIGN This double-blind randomized controlled trial recruited 1729 women from the United Kingdom, Singapore, and New Zealand, aged 18 to 38 years, and planning conception between 2015 and 2017. The effects of the nutritional intervention compared with those of a standard micronutrient supplement (control), taken at preconception and throughout pregnancy, were examined for the secondary outcomes of peripartum events using multinomial, Poisson, and linear regression adjusting for site, ethnicity, and important covariates. RESULTS Of the women who conceived and progressed beyond 24 weeks' gestation with a singleton pregnancy (n=589), 583 (99%) provided peripartum data. Between women in the intervention (n=293) and control (n=290) groups, there were no differences in rates of labor induction, oxytocin augmentation during labor, instrumental delivery, perineal trauma, and intrapartum cesarean delivery. Although duration of the first stage of labor was similar, the second-stage duration was 20% shorter in the intervention than in the control group (adjusted mean difference, -12.0 [95% confidence interval, -22.2 to -1.2] minutes; P=.029), accompanied by a reduction in operative delivery for delayed second-stage progress (adjusted risk ratio, 0.61 [0.48-0.95]; P=.022). Estimated blood loss was 10% lower in the intervention than in the control group (adjusted mean difference, -35.0 [-70.0 to -3.5] mL; P=.047), consistent with previous findings of reduced postpartum hemorrhage. CONCLUSION Supplementation with a specific combination of myo-inositol, probiotics, and micronutrients started at preconception and continued in pregnancy reduced the duration of the second stage of labor, the risk of operative delivery for delay in the second stage, and blood loss at delivery.

Abstract
INTRODUCTION Implementation research with pre- and post-comparison was planned to improve the quality of evidence-based intrapartum care services in Indian medical schools. We present the baseline study results to assess the status of adherence to intrapartum evidence-based practices (IP-EBP) in study schools in 3 states in India and the perception of the faculty. METHODS A concurrent mixed-methods approach was used to conduct the baseline assessment in 9 medical schools in Rajasthan, Gujarat, and Union Territory from October 2018 to June 2019. IP-EBP among pregnant women in uncomplicated first (n=135), second (n=120), and third stage (n=120) of labor were observed using a predesigned, pretested checklist quantitatively. We conducted in-depth interviews with 33 obstetrics and gynecology faculty to understand their perceptions of intrapartum practices. Quantitative data were analyzed using SPSS (version 22). COM-B (Capability, Opportunity, and Motivation Behavior) model was used to understand the behaviors, and thematic analysis was done for the qualitative data. FINDINGS Unindicated augmentation of labor was done in 64.4%, fundal pressure applied in 50.8%, episiotomy done in 58.3%, and delivery in lithotomy position was performed in 86.7% of women in labor. CONCLUSIONS Intrapartum practices that are not recommended were routinely practiced in the study medical schools due to a lack of staff awareness of evidence-based practices and incorrect beliefs about their impact.

Abstract
Background: Augmentation of labour (AOL) is the most common intervention to treat labour dystocia. Previous research reported extensive disparities in AOL rates across countries and institutions. Despite its widespread use, women’s views on and experiences of intrapartum augmentation with infused synthetic oxytocin are limited. Methods: A qualitative evidence synthesis on women’s views and experiences of AOL with synthetic oxytocin after spontaneous onset of labour will be conducted. Qualitative studies and studies employing a mixed methods design, where qualitative data can be extracted separately, will be included, as will surveys with open-ended questions that provide qualitative data. A systematic search will be performed of the databases: MEDLINE, CINAHL, EMBASE, PsycINFO, Maternity and Infant Care and Web of Science Core Collection from the date of inception. The methodological quality of included studies will be assessed using the Evidence for Policy and Practice Information and Co-ordinating Centre’s appraisal tool. A three-stage approach, coding of data from primary studies, development of descriptive themes and generation of analytical themes, will be used to synthesise findings. Confidence in findings will be established by the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research. Discussion: This qualitative evidence synthesis may provide valuable information on women’s experiences of AOL and contribute to a review of clinical practice guidelines for maternity care providers.

Oxytocin administration for induction and augmentation of labour in polish maternity units - an observational study. BMC Pregnancy Childbirth 2021; 21:764. [PMID: 34763657 PMCID: PMC8582102 DOI: 10.1186/s12884-021-04190-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Accepted: 10/12/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND There is not enough data regarding practices and protocols on the dose of oxytocin administrated to women during labour. Empirical evidence indicates that compliance with the guidelines improves the quality of healthcare and reduces adverse effects. The study aimed to evaluate practices of oxytocin provision for labour induction and augmentation in two maternity units in Poland. METHODS The article presents a prospective observational study. Data from 545 (n = 545) labours was collected in two maternity units. First, the total dose (the total amount of oxytocin provided from the beginning in the labour ward until delivery including the III and IV stage of labour) and cumulative dose of oxytocin (the amount of oxytocin given until the birth of the neonate) administered to women during labour was calculated. Then, the relationship between the cumulative dose of oxytocin and short term perinatal outcomes (mode of delivery, use of epidural anaesthesia, Apgar scores, birth weight and postpartum blood loss) was analysed. Finally, the compliance of oxytocin supply during labour with national guidelines in the following five criteria: medium, start dose, escalation rate, interval, the continuation of infusion after established labour was examined. RESULTS The average cumulative dose of oxytocin administrated to women before birth was 4402 mU following labour induction and 2366 mU following labour augmentation. The actual administration of oxytocin deviated both from the unit and national guidelines in 93.6% of all observed labours (mainly because of continuation of infusion after established labour). We found no statistically significant correlation between the cumulative dose of oxytocin administered and mode of delivery, immediate postpartum blood loss or Apgar scores. There was no observed effect of cumulative dose oxytocin on short-term perinatal outcomes. The two units participating in the study had similar protocols and did not differ significantly in terms of total oxytocin dose, rates of induction and augmentation - the only observed difference was the mode of delivery. CONCLUSIONS The study showed no effect of the mean cumulative oxytocin dose on short-term perinatal outcomes and high rate of non-compliance of the practice of oxytocin administration for labour induction and augmentation with the national recommendations. Cooperation between different professional groups of maternity care providers should be considered in building national guidelines for maternity care.. Further studies investigating possible long-term effects of the meant cumulative dose of oxytocin and the reasons for non-compliance of practice with guidelines should be carried out.

Abstract
Normal labor is identified as regular uterine contractions in addition to dilation and effacement of the cervix. It is necessary to define normal labor in order to delineate when a woman's labor pattern diverges from that observed in most women. Labor irregularities are subdivided into protraction disorders and arrest disorders. Identifying abnormal labor patterns and initiating appropriate interventions is essential because prolonged labor is associated with an increase in perinatal morbidity. The aim of this review was to delineate both normal labor progress and also discuss the current evidence-based diagnosis and treatment of protraction and arrest disorders. Many subtleties go into defining the boundaries of the first and second stages of labor. Historically, the Friedman curve established normal limits; but currently Zhang has advanced these definitions by accounting for current demographical characteristics and practice environments. The most significant variables for defining normal progress of labor are parity and regional anesthesia status. The most common causes of labor abnormalities are uterine inactivity, obesity, cephalopelvic disproportion and fetal malposition. Risks of extending the first and/or second stage of labor include postpartum hemorrhage, intraamniotic infection and potentially an increase in neonatal adverse outcomes. The management of labor disorders consists of oxytocin administration, amniotomy, intrauterine pressure catheter use and shared decision-making regarding proceeding with expectant management, operative vaginal delivery or cesarean delivery after weighing the risks and benefits of each option. The decision to extend the duration of labor is personalized for each mother-baby dyad and should be agreed upon depending on individual maternal and fetal circumstances.

Abstract
Introduction The aim of this study was to compare childbirth experiences and experience of labor pain in primiparous women who had received high‐ vs low‐dose oxytocin for augmentation of delayed labor. Material and methods A multicenter, parallel, double‐blind randomized controlled trial took place in six Swedish labor wards. Inclusion criteria were healthy primiparous women at term with uncomplicated singleton pregnancies, cephalic fetal presentation, spontaneous onset of labor, confirmed delayed labor progress and ruptured membranes. The randomized controlled trial compared high‐ vs low‐dose oxytocin used for augmentation of a delayed labor progress. The Childbirth Experience Questionnaire version 2 (CEQ2) was sent to the women 1 month after birth. The CEQ2 consists of 22 items in four domains: Own capacity, Perceived safety, Professional support and Participation. In addition, labor pain was reported with a visual analog scale (VAS) 2 hours postpartum and 1 month after birth. The main outcome was the childbirth experience measured with the four domains of the CEQ2. The clinical trial number is NCT01587625. Results The CEQ2 was sent to 1203 women, and a total of 1008 women (83.8%) answered the questionnaire. The four domains of childbirth experience were scored similarly in the high‐ and low‐dose oxytocin groups of women: Own capacity (P = .36), Perceived safety (P = .44), Professional support (P = .84), Participation (P = .49). VAS scores of labor pain were reported as similar in both oxytocin dosage groups. Labor pain was scored higher 1 month after birth compared with 2 hours postpartum. There was an association between childbirth experiences and mode of birth in both the high‐ and low‐dose oxytocin groups. Conclusions Different dosage of oxytocin for augmentation of delayed labor did not affect women’s childbirth experiences assessed through CEQ2 1 month after birth, or pain assessment 2 hours or 1 month after birth.

Abstract
OBJECTIVES Current labour practices have seen an acceleration in interventions to either initiate, monitor, accelerate, or terminate the physiological process of pregnancy and childbirth. This study aimed to describe and analyse the use of interventions in childbirth in Denmark over almost two decades (2000-2017). We also examined the extent to which contemporary care adheres to current international recommendations towards restricted use of interventions. STUDY DESIGN A national retrospective Danish register-based cohort study including all nulliparous women with term births with singleton pregnancy and a foetus in cephalic between the years 2000 and 2017 (n = 380,326 births). Multivariate regression analyses with adjustment for change in population were performed. MAIN OUTCOME MEASURES Induction of labour, epidural analgesia, and augmentation of labour. RESULTS Between 2000/2001 and 2016/2017, the prevalence increased for induction of labour from 5.1% to 22.8%, AOR 4.84, 95% CI [4.61-5.10], epidural analgesia from 10.5% to 34.3% (AOR 4.10, 95% CI [3.95-4.26]), and augmentation of labour decreased slightly from 40.1% to 39.3% (AOR 0.84, 95% CI [0.81-0.86]). Having more than one of the three mentioned interventions increased from 12.8% in to 30.9%. CONCLUSIONS The number of interventions increased during the study period as well as the number of interventions in each woman. As interventions may interfere in physiological labour and carry the risk of potential short- and long-term consequences, the findings call for a careful re-evaluation of contemporary maternity care with a "first, do no harm" perspective.

Abstract
INTRODUCTION One of the most common complications during labor is prolonged labor (dystocia), which is associated with risks for the mother and fetus. Dystocia is usually treated with oxytocin, which is also used to induce labor. Oxytocin may not have the desired effect of progress and can negatively affect the fetus, thus resulting in an emergency caesarean section (CS). The aim of this study was to describe obstetric practice, use of oxytocin and its association with an emergency CS. METHODS A cross-sectional retrospective register study was conducted that included all women who gave birth during 2014 and 2015 at a hospital in a large city in Pakistan. RESULTS A total of 6652 women gave birth to 6767 newborns, 66.8% were multiparous and 33.2% primiparous women. Of the primiparous women, 78.9% had a spontaneous vaginal birth, 1.2% an elective CS and 14.4% an emergency CS. Of the multiparous women, 81.9% had a spontaneous vaginal birth, 8.0% an elective CS and 6.7% an emergency CS. Operative vaginal birth was 2.1% among primiparous and 0.2% among multiparous women. Oxytocin for induction or augmentation was administered to 60.0% of primiparous and 30.5% of multiparous women. Oxytocin during the first stage of labor was associated with an increased risk for emergency CS for both primiparous and multiparous women. CONCLUSIONS Despite the association between oxytocin and emergency CS, the CS rate was low in this hospital. The majority of the women gave birth vaginally, even with a breech presentation. Few operative vaginal births were performed.

Abstract
Objective To compare synthetic oxytocin infusion regimens used during labour, calculate the International Units (IU) escalation rate and total amount of IU infused over eight hours. Design Observational study Setting Twelve countries, eleven European and South Africa. Sample National, regional or institutional-level regimens on oxytocin for induction and augmentation labour Methods Data on oxytocin IU dose, infusion fluid amount, start dose, escalation rate and maximum dose were collected. Values for each regimen were converted to IU in 1000ml diluent. One IU corresponded to 1.67μg for doses provided in grams/micrograms. IU hourly dose increase rates were based on escalation frequency. Cumulative doses and total IU amount infused were calculated by adding the dose administered for each previous hour. Main Outcome Measures Oxytocin IU dose infused Results Data were obtained on 21 regimens used in 12 countries. Details on the start dose, escalation interval, escalation rate and maximum dose infused were available from 16 regimens. Starting rates varied from 0.06 IU/hour to 0.90 IU/hour, and the maximum dose rate varied from 0.90 IU/hour to 3.60 IU/hour. The total amount of IU oxytocin infused, estimated over eight hours, ranged from 2.38 IU to 27.00 IU, a variation of 24.62 IU and an 11-fold difference. Conclusion Current variations in oxytocin regimens for induction and augmentation of labour are inexplicable. It is crucial that the appropriate minimum infusion regimen is administered because synthetic oxytocin is a potentially harmful medication with serious consequences for women and babies when inappropriately used. Estimating the total amount of oxytocin IU received by labouring women, alongside the institution’s mode of birth and neonatal outcomes, may deepen our understanding and be the way forward to identifying the optimal infusion regimen.

Abstract
Augmentation of labour aims at improving the efficiency of uterine contractions in order to reduce maternal and foetal adverse outcomes associated with prolonged labour. This review covers the current best practice for different methods of augmentation of labour, namely, artificial rupture of membranes and oxytocin infusion as a prevention of, or therapy for, prolonged labour. The review highlights essential practice points and identifies knowledge gaps for future research in this important area of clinical obstetric practice.

Clinical experiences with the use of oxytocin injection by healthcare providers in a southwestern state of Nigeria: A cross-sectional study. PLoS One 2019; 14:e0208367. [PMID: 31600195 PMCID: PMC6786624 DOI: 10.1371/journal.pone.0208367] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Accepted: 09/15/2019] [Indexed: 12/05/2022] Open
Abstract
Background Postpartum hemorrhage (PPH) is a leading cause of maternal mortality in Nigeria and in most low- and middle-income countries. The World Health Organization (WHO) strongly recommends oxytocin as effective, affordable, and the safest drug of first choice in the prevention and treatment of PPH in the third stage of labor. However, there are concerns about its quality. Very high prevalence of poor-quality oxytocin, especially in Africa and Asia, has been reported in literature. Excessive and inappropriate use of oxytocin is also common in low-resource settings. Objective To assess clinical experiences with quality of oxytocin used by healthcare providers in Lagos State, Nigeria. Methods This was a descriptive cross-sectional study conducted in 2017, with 705 respondents (doctors and nurses) who use oxytocin for obstetrics and gynecological services recruited from 195 health facilities (public and registered private) across Lagos State. Data collection was quantitative, using a pretested self-administered questionnaire. Data analysis was performed with IBM SPSS version 21. Statistical significance was set at 5 percent (p<0.05). Ethical approval was obtained from Lagos University Teaching Hospital Health Research Ethics Committee. Results Only 52 percent of the respondents knew oxytocin should be stored at 2°C to 8°C. About 80 percent of respondents used oxytocin for augmentation of labor, 68 percent for induction of labor, 51 percent for stimulation of labor, and 78 percent for management of PPH. Forty-one percent used 20IU and as much as 10% used 30IU to 60IU for management of PPH. About 13 percent of respondents reported believing they had used an ineffective brand of oxytocin in their practice. Just over a third (36%) had an available means of documenting or reporting perceived ineffectiveness of drugs in their facility; of these, only about 12 percent had pharmacovigilance forms in their facilities to report the ineffectiveness. Conclusion The inappropriate and inconsistent use of oxytocin, especially overdosing, likely led to the high perception of medicine effectiveness among respondents. This is coupled with lack of suspicion of medicine ineffectiveness by clinicians as a possible root cause of poor treatment response or disease progression. Poor knowledge of oxytocin storage and consequent poor storage practices could have contributed to the ineffectiveness reported by some respondents. It is necessary to establish a unified protocol for oxytocin use that is strictly complied with. Continuous training of healthcare providers in medicine safety monitoring is advocated.

Abstract
Introduction In high‐income countries the majority of pregnancies have a good outcome, and many adverse obstetric outcomes rarely occur. This makes demonstrating clinically relevant and statistically significant effects of new interventions a challenge. The objective of the study was to report incidences of important obstetric outcomes and to calculate sample sizes for tentative studies. Material and methods The study was a registry‐based study. Data were retrieved from the Danish Medical Birth Registry and included all deliveries in Denmark from 2008 to 2015. The total population included 465 919 deliveries. The study population comprised intended vaginal deliveries with a single fetus in cephalic presentation at term (n = 381 567). Incidences were reported for 20 outcomes considering the relevance for the patients and the severity of the outcomes. We calculated the sample sizes required in tentative obstetric studies to detect risk reductions of 25 and 50%, for tests at the 5% level, using a power of 80 and 90%. For the randomized controlled trials we calculated the sample size required for comparing two proportions with equal‐sized groups. For the cohort study we calculated the sample size also required for two proportions but with unequal sized groups. Outcome measures for sample size calculation were neonatal mortality, Apgar score <7 at 5 minutes and emergency cesarean section. Results The incidence of neonatal mortality, Apgar score <7 at 5 minutes and emergency cesarean section was 0.05, 0.58 and 10.5%, respectively. Using neonatal mortality as the outcome in a tentative randomized controlled trial with an expected risk reduction of 50% and power of 80%, our calculation showed a sample size of 195 036 deliveries. Using Apgar score <7 at 5 minutes or emergency cesarean section as the outcome, 16 254 and 818 deliveries, respectively, were required. In tentative cohort studies, the required sample sizes were larger due to the unequal proportion of exposed/non‐exposed women. Conclusions Most adverse obstetric outcomes occur rarely; thus, very large sample sizes are required to achieve adequate statistical power in randomized controlled trials. Multicenter studies, international collaborations or alternative study designs to randomized controlled trials could be considered.

Abstract
PROBLEM Researchers have prioritized understanding and differentiating the pathophysiologic mechanisms to improve precision in diagnosis and individualization of care, however the experiences of women with labor dystocia have been underexamined. BACKGROUND Management of labor dystocia has been identified as an opportunity for reducing the rate of unnecessary cesarean births and the associated risks to women and their infants. This meta-synthesis explores women's experiences of labor dystocia to enrich the discussion of care practices and contextualize discussions of shared decision making in what is most meaningful to women. QUESTIONS How does prolonged labor influence women's experience of birth and motherhood? What are women's experiences with decision-making about labor augmentation during prolonged labor? METHODS Sandelowski and Barroso's meta-synthesis approach was used to analyze primary qualitative studies of women's experiences of labor dystocia. Through inductive thematic synthesis and reciprocal translation, themes identified in qualitative research, quotations, and coded meaning units were aggregated and interpreted into derived categories and themes. FINDINGS Fourteen qualitative studies were analyzed. Women experienced labor dystocia as a transition from healthy labor to abnormal labor requiring medical support consistent with Transition Theory by Meleis. Six new categories and thirty themes were identified. Each category and theme reflects a distinct component of the experience of labor dystocia. DISCUSSION/CONCLUSION There is wide variation in the way women experience labor dystocia. Facilitation of the transition from healthy labor to labor dystocia can be supported by a fluid, adaptable method of caring for women in the face of uncertainty and loss of choice.

Abstract
BACKGROUND Globally, Caesarean section (CS) rates are mounting and currently exceed the safe upper limit of 15%. Monitoring CS rates using clinical indications and obstetric sub-group analysis could confirm that women in need have been served. In Bangladesh, the reported CS rate was 31% in 2016, and almost twice that rate in urban settings. Delivering in the private healthcare sector was a strong determinant. This study uses Robson Ten Group Classification System (TGCS) to report CS rates in urban Bangladesh. The clinical causes and determining factors for CS births have also been examined. METHODS This record linkage cross-sectional survey was undertaken in 34 urban for-profit private hospitals having CS facilities during the period June to August 2015. Data were supplied by inpatient case records and operation theatre registers. Descriptive analyses were performed to calculate the relative size of each group; the group-specific CS rate, and group contribution to total CS and overall CS rate. CS indications were grouped into eleven categories using ICD 10 codes. Binary logistic regression was performed to explore the determinants of CS. RESULTS Out of 1307 births, delivery by CS occurred in 1077 (82%). Three obstetric groups contributed the most to overall CS rate: previous CS (24%), preterm (23%) and term elective groups (22%). The major clinical indications for CS were previous CS (35%), prolonged and obstructed labor (15%), fetal distress (11%) and amniotic fluid disorder (11%). Multiple gestation, non-cephalic presentation, previous bad obstetric history were positive predictors while oxytocin used for labour induction and increased parity were negative predictors of CS. CONCLUSIONS As the first ever study in urban private for-profit health facilities in Bangladesh, this study usefully identifies the burden of CS and where to intervene. Engagement of multiple stakeholders including the private sector is crucial in planning effective strategies for safe reduction of CS.

Helbig S, Petersen A, Sitter E, Daly D, Gross MM. Inter-institutional variations in oxytocin augmentation during labour in German university hospitals: a national survey. BMC Pregnancy Childbirth 2019; 19:238. [PMID: 31288780 PMCID: PMC6617790 DOI: 10.1186/s12884-019-2348-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Accepted: 05/31/2019] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND There are several international guidelines on oxytocin regimens for induction and augmentation of labour, but no agreement on a standardised regimen in Germany. This study collated and reviewed the oxytocin regimens used for labour augmentation in university hospitals, with the long-term aim of contributing to the development of a national clinical guideline. METHODS Germany has 34 university hospital compounds, representing 39 maternity units. In this observational study we asked units to provide standard operational procedures on oxytocin augmentation during labour or provide the details in a structured survey. Data were collected on the dosage of oxytocin, type and volume of solutions used, indications and contraindications for use and discontinuation, case-specific administration, and on who developed the procedures. Findings were analysed descriptively. RESULTS A total of 35 (90%) units participated in this study. Standard operating procedures were available in 24 units (69%), seven units (20%) did not have procedures and information was missing from four units (11%). Midwives participated in the development of standard operating procedures in 15 units (43%). Infusions were most commonly prepared using six units of oxytocin in 500 ml 0.9% normal saline solution (12 mU/ml). The infusions were started at 120 mU/hour and increased by 120 mU/hour at 20-min intervals up to a maximum dosage of 1200 mU/hour. The most common indication for use was delayed progress in labour. Infusions were stopped when uterine contractions became hypertonic and/or the fetal heart rate showed signs of distress. Most of the practices described aligned with international guidance. All units used reduced oxytocin dosages for women with a history of previous caesareans section, as recommended in the international guidelines, and restrictive use was advised in multiparous women. The main difference between units related to combined use of amniotomy and oxytocin, recommended by three guidelines but used in only four maternity units (11%). CONCLUSIONS While there was considerable variation in the oxytocin augmentation procedures, most but not all practices used in these 35 German maternity units were comparable. Establishing a national guideline on the criteria for and administration of oxytocin for augmentation of labour would eliminate the observed differences and minimise risk of administration and medication error.

Abstract
Maternity care in the United States continues to be intervention intensive. The routine use of intravenous fluids, restrictions on eating and drinking, continuous electronic fetal monitoring, epidural analgesia, and augmentation of labor characterize most U.S. births. The use of episiotomy has decreased but is still higher than it should be. These interventions disturb the normal physiology of labor and birth and restrict women's ability to cope with labor. The result is a cascade of interventions that increase risk, including the risk of cesarean surgery, for women and babies. This paper describes the use and effect of routine interventions on the physiologic process of labor and birth and identifies the unintended consequences resulting from the routine use of these interventions in labor and birth.

Abstract
BACKGROUND The timing of hospital admission for women with spontaneous labor onset and the criteria used to assess active labor progress and diagnose labor dystocia may significantly influence women's risk for primary cesarean birth. Our aims were to assess associations of labor status at admission (i.e., preactive or active) and active labor progress (i.e., dystocic or physiologic) with oxytocin augmentation, cesarean birth, and adverse neonatal outcome rates. METHODS A sample of low-risk, nulliparous women admitted to hospitals for spontaneous labor onset was extracted from the Consortium on Safe Labor (n = 27 077). Binomial logistic regression was used to assess associations between labor classifications and outcomes. RESULTS At admission, 68.0% of women were in preactive labor and 32.0% were in active labor. Cesarean rates for these groups were 18.0% and 7.2%, respectively (adjusted odds ratio [AOR] 2.69; 95% CI 2.45-2.96). Oxytocin augmentation and adverse neonatal outcomes were more likely for women admitted in preactive labor. Among women admitted in active labor, 9.3% experienced labor dystocia and 90.7% progressed physiologically. Cesarean rates for these groups were 20.4% and 5.9%, respectively (AOR 3.02; 95% CI 2.45-3.73). Nearly half of the cesareans performed for dystocia among women admitted in active labor occurred when cervical dilation was physiologic. Oxytocin augmentation and adverse neonatal outcomes were more likely when active labor was dystocic. CONCLUSIONS Adoption of evidence-based, standardized approaches for diagnosing active labor onset, assessing labor progress, and diagnosing dystocia may safely decrease oxytocin augmentation and cesarean birth rates in the United States.

Abstract
Background The current guideline for oxytocin regimens in the abnormal labor of delivery is continuous infusion. The objective of the present study was to compare effects and safety measures of various available regimens of oxytocin in abnormal labor delivery. Material/Methods In this clinical experimental study, a total of 900 pregnant women admitted for delivery were randomized into 5 group with 162 each. Pregnant women received oxytocin as continuous administration of 16 mU/min (Group I), 1 mU/min (group II), 4 mU/min (group III), 5 mU/min quarter-hourly (group IV), and through a syringe pump (group V). Measurement of the expense of delivery, the ratio of the instrumental delivery, and the other secondary outcome measures was performed to find the best regimen of oxytocin. The 2-tailed paired t test and Mann-Whitney U test following Dunnett’s multiple comparison tests were used at 95% confidence level. Results Pulsatile delivery had least risk of instrumental delivery as compared to continuous infusion (p<0.0001, q=6.663) and normal-frequency low-dose (p<0.0001, q=5.638) of oxytocin. The time required from infusion to delivery was longer for group II (p=0.001, q=2.925), group IV (p<0.0001, q=4.829), and group V (p<0.0001, q=41.456) than for group I. The expense of delivery was: group I < group II < group IV < group III < group V. Conclusions High-dose and pulsatile preparation of oxytocin had reduced risks of operative delivery vs. continuous administration.

Abstract
OBJECTIVE to evaluate the impact of the implementation of evidence-based practices on normal delivery care. METHOD quasi-experimental, before-and-after intervention study conducted in a public maternity hospital, Amapá. Forty-two professionals and 280 puerperal women were interviewed and data from 555 medical records were analyzed. The study was developed in three phases: baseline audit (phase 1), educational intervention (phase 2) and post-intervention audit (phase 3). RESULTS after the intervention, there was an increase of 5.3 percentage points (p.p.) in the normal delivery rate. Interviews with the women revealed a significant increase of the presence of companions during labor (10.0 p.p.) and of adoption of the upright or squatting position (31.4 p.p.); significant reduction of amniotomy (16.8 p.p.), lithotomy position (24.3 p.p.), and intravenous oxytocin (17.1 p.p.). From the professionals' perspective, there was a statistical reduction in the prescription/administration of oxytocin (29.6 p.p.). In the analysis of medical records, a significant reduction in the rate of amniotomy (29.5 p.p.) and lithotomy position (1.5 p.p.) was observed; the rate of adoption of the upright or squatting position presented a statistical increase of 2.2 p.p. CONCLUSIONS there was a positive impact of the educational intervention on the improvement of parturition assistance, but the implementation process was not completely successful in the adoption of scientific evidence in normal delivery care in this institution.

Lack of controlled studies investigating the risk of postpartum haemorrhage in cesarean delivery after prior use of oxytocin: a scoping review. BMC Pregnancy Childbirth 2017; 17:399.

Abstract
BACKGROUND Postpartum haemorrhage (PPH) is a major cause of maternal mortality and morbidity worldwide. Experimental and clinical studies indicate that prolonged oxytocin exposure in the first or second stage of labour may be associated with impaired uterine contractility and an increased risk of atonic PPH. Therefore, particularly labouring women requiring cesarean delivery constitute a subset of patients that may exhibit an unpredictable response to oxytocin. We mapped the evidence for comparative studies investigating the hypothesis whether the risk for PPH is increased in women requiring cesarean section after induction or augmentation of labour. METHODS We performed a systematic literature search for clinical trials in Medline, Embase, Web of Science, and the Cochrane Library (May 2016). Additionally we searched for ongoing or unpublished trials in clinicaltrials.gov and the WHO registry platform. We identified a total of 36 controlled trials investigating the exogenous use of oxytocin in cesarean section. Data were extracted for study key characteristics and the current literature literature was described narratively. RESULTS Our evidence map shows that the majority of studies investigating the outcome PPH focused on prophylactic oxytocin use compared to other uterotonic agents in the third stage of labour. Only 2 dose-response studies investigated the required oxytocin dose to prevent uterine atony after cesarean delivery for labour arrest. These studies support the hypotheses that labouring women exposed to exogenous oxytocin require a higher oxytocin dose after delivery than non-labouring women to prevent uterine atony after cesarean section. However, the study findings are flawed by limitations of the study design as well as the outcome selection. No clinical trial was identified that directly compared exogenous oxytocin versus no oxytocin application before intrapartum cesarean delivery. CONCLUSION Despite some evidence from dose-response studies that the use of oxytocin may increase the risk for PPH in intrapartum cesarean delivery, current research has not investigated the prepartal application of oxytocin in well controlled clinical trials. It was striking that most studies on exogenous oxytocin are focused on PPH prophylaxis in the third stage of labour without differing between the indications of cesarean section and hence the prepartal oxytocin status.

Abstract
This study aims to determine relationships between intrapartum factors, neonatal characteristics, skin-to-skin contact (SSC), and early breastfeeding initiation after spontaneous vaginal and Caesarean section or operative vaginal birth. A total of 915 mother-newborn dyads were considered in a hypothetical model based on integrated concepts of breastfeeding initiation model, infant learning framework, and attachment theory. Multiple-group path analysis was used to determine whether differences exist between effects of immediate SSC (≤30 min) on early breastfeeding initiation in different modes of birth. SSC, mode of birth, labour duration, and neonatal intensive care unit admission were significantly associated with early breastfeeding initiation, as indicated by the path analysis model, which included all samples. Women with immediate SSC were more likely to initiate early breastfeeding in different modes of birth. In the spontaneous vaginal birth group, women showed a lower likelihood of initiating early breastfeeding when their neonates were admitted to the neonatal intensive care unit and presented an Apgar score of <7 at 1 min. Multiple-group analysis showed no significant difference between effects of immediate SSC on early breastfeeding initiation in different modes of birth (critical ratio = -0.309). Results showed that models satisfactorily fitted the data (minimum discrepancy divided by degrees of freedom = 1.466-1.943, goodness of fit index = 0.981-0.986, comparative fit index = 0.947-0.955, and root mean square error of approximation = 0.023-0.032). Our findings emphasize the crucial importance of prioritizing promotion of immediate SSC under different modes of birth.

Abstract
Background Labor that progresses faster than anticipated may lead to unplanned out-of-hospital births. With the aim to improve planning of transportation to birthing institutions, this study investigated predictors of time to completion for the first stage of labor conditional on cervical opening (conditional time) in multiparous women at term. Methods We performed a retrospective analysis of partograms for women in Robson’s group 3 who delivered at one hospital from 2003 to 2013. A generalized additive mixed model was fitted, accounting for possible non-linear relationships between the predictor variables and outcome, e.g. the time from each cervical measurement to full dilation, using multiple measurements for each woman. The following predictors were included: cervical dilation (cm), parity (1, 2, or ≥3 previous vaginal births), oxytocin infusion (no/yes), epidural (no/yes), maternal age (years), maternal height (cm), body mass index (BMI, kg/m2), birthweight (kg), spontaneous rupture of membranes (no/yes). A modified regression model with gestational age (days) instead of birthweight was used to predict conditional time to full cervical dilation for combinations of the most relevant predictors. Results A total of 1753 partograms were included in the analysis. The strongest predictors were birthweight, epidural and oxytocin use, and spontaneous rupture of membranes, along with cervical measurements. For birthweight, there was an almost 40% increase in time to full cervical dilation for each 1-kg increment. Conditional time was on average 23% longer in cases with epidural use and 53% longer in cases requiring oxytocin augmentation. Spontaneous rupture of the membranes shortened conditional time by 31%. Maternal age was not associated with the outcome, while increasing BMI and parity modestly reduced conditional time. Conclusions Higher parity, lower fetal weight (gestational age), and spontaneous rupture of the membranes are associated with more rapid labor.

Abstract
OBJECTIVE Describing the obstetric care provided in public maternity hospitals during normal labour using the Bologna Score in the city of Natal, Northeastern Brazil. METHOD A quantitative cross-sectional study conducted with 314 puerperal women. Data collection was carried out consecutively during the months of March to July 2014. RESULTS Prenatal care was provided to 95.9% of the mothers, beginning around the 1st trimester of pregnancy (72.3%) and having seven or more consultations (51%). Spontaneous vaginal delivery was planned for 88.2% women. All laboring women were assisted by a health professional, mostly by a physician (80.6%), and none of them obtained 5 points on the Bologna Score due to the small percentage of births in non-supine position (0.3%) and absence of a partogram (2.2%). A higher number of episiotomies were observed among primiparous women (75.5%). CONCLUSION The score obtained using the Bologna Index was low. Thus, it is necessary to improve and readjust the existing obstetrical model. OBJETIVO Descrever a assistência obstétrica prestada em maternidades públicas municipais durante o parto normal na cidade de Natal, Nordeste do Brasil, com uso do Índice de Bologna. MÉTODO Estudo transversal com abordagem quantitativa, desenvolvido com 314 puérperas. A coleta de dados processou-se de forma consecutiva durante os meses de março a julho de 2014. RESULTADOS A assistência pré-natal foi prestada a 95,9% das puérperas, com início em torno do 1º trimestre de gestação (72,3%) e realização de sete ou mais consultas (51%). O parto vaginal espontâneo foi planejado para 88,2% mulheres. Todas as parturientes foram assistidas por um profissional de saúde, especialmente pelo médico (80,6%) e nenhuma obteve 5 pontos no Índice de Bologna em virtude dos baixos percentuais de partos em posição não supina (0,3%) e ausência do partograma (2,2%). Houve maior número de episiotomias em primíparas (75,5%). CONCLUSÃO A pontuação obtida por meio do Índice de Bologna foi baixa. Desse modo, é preciso melhorar e readequar o modelo obstétrico vigente.

Abstract
BACKGROUND Unnecessary routine interventions in uncomplicated labour and birth, like cardiotocography (CTG), amniotomy, use of scalp electrode and oxytocin treatment, are associated with further interventions that could harm the woman and the infant. A four year Action Research (AR) project was done on a labour ward to enhance the capacity of local midwives in the promotion of physiological labour and birth. AIM To describe the use of interventions during labour and birth in healthy women at term with spontaneous onset of labour, before and after initiation of an Action Research project. METHODS A retrospective before and after comparative study of clinical records from 2009 (before) and 2012 (after), based on a random selection of records from primiparous and multiparous women. Outcome measures were duration of admission CTG, frequency of admission CTG over 30min, frequency of amniotomy, use of scalp electrode, and frequency of oxytocin augmentation in spontaneous labour. RESULTS 903 records were included. The duration of admission CTG (p=0.001), frequency of admission CTG duration over 30min (p=<0.001), the use of scalp electrodes (p=<0.001), and use of oxytocin augmentation of spontaneous labour (p=0.014) were reduced significantly after initiation of the AR project. There were no significant differences in frequency of amniotomy, duration of total CTG, postpartum bleeding, sphincter tears, Apgar score <5 at 5min, and mode of birth. CONCLUSION Following an AR project, several interventions were reduced during labour and birth. Controlled studies in other settings are needed to assess the impact of collaborative action on decreasing unnecessary interventions.

Abstract
OBJECTIVE To determine antepartum and intrapartum factors that are associated with admission to neonatal intensive care unit (NICU) among infants delivered between 36.0 and 42.0 weeks at our institution. METHODS The retrospective cohort study included 73 consecutive NICU admissions and 375 consecutive non-NICU admissions. Data on demographic, antepartum, intrapartum and neonatal factors were collected. The primary endpoint defined was admission to NICU. Univariate analyses using the Student's t-test, Mann-Whitney U-test, χ2 Fisher's exact test was performed along with multivariate analysis of significant non-redundant variables. RESULTS Those with a significantly higher risk of NICU admission underwent induction of labor with prostaglandin analogs (12.5% vs. 24.7%, P=0.007). Length of first stage ≥720 min (33.5% vs. 51.9%, P=0.011), length of second stage of labor ≥240 min (10.6% vs. 31.6%, P<0.001) and prolonged rupture of membranes ≥120 min (54.0% vs. 80.0%, P=0.001) were all associated with an increased chance of NICU admission. Intrapartum factors predictive of NICU admission included administration of meperidine (11.7% vs. 27.4%, P<0.001), presence of preeclampsia (5.5% vs. 0.8%, P=0.015), use of intrapartum IV antihypertensives (1.1% vs. 13.7%, P<0.001), maternal fever (5.3% vs. 31.5%, P<0.001), fetal tachycardia (1.9% vs. 12.3%, P<0.001), and presence of meconium (30% vs. 8%, P<0.001). CONCLUSION Identification of modifiable risk factors may reduce neonatal morbidity and mortality. Results from this study can be used to develop and validate a risk model based on combined antepartum and intrapartum risk factors.

Front Med (Lausanne) 2016; 3:26. [PMID: 27446924 PMCID: PMC4921453 DOI: 10.3389/fmed.2016.00026] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2016] [Accepted: 05/21/2016] [Indexed: 11/29/2022] Open
Abstract
Background Rates of cesarean section increase worldwide, and the components of this increase are partially unknown. A strong role is prescribed to dystocia, and at the same time, the diagnosis of dystocia is highly subjective. Previous studies indicated that risk of cesarean is higher when women are admitted to the hospital early in the labor. Methods We examined data on 1,202 nulliparous women with singleton, vertex pregnancies and spontaneous labor onset. We selected three groups based on cervical dilatation at admission: early (0.5–1.5 cm, N = 178), intermediate (2.5–3.5 cm, N = 320), and late (4.5–5.5 cm, N = 175). The Kaplan–Meier estimator was used to analyze the risk of delivery by cesarean section at a given dilatation, and thin-plate spline regression with a binary outcome (R library gam) to assess the form of the associations between the cesarean section in either the first or second stage versus vaginal delivery and dilatation at admission. Results Women who were admitted to labor early had a higher risk of delivery by cesarean section (18 versus 4% in the late admission group), while the risk of instrumental delivery did not differ (24 versus 24%). Before 4 cm dilatation, the earlier a woman was admitted to labor, the higher was her risk of delivery by cesarean section. After 4 cm dilatation, however, the relationship disappeared. These patterns were true for both first and second stage cesarean deliveries. Oxytocin use was associated with a higher risk of cesarean section only in the middle group (2.5–3.5 cm dilatation at admission). Conclusion Early admission to labor was associated with a significantly higher risk of delivery by cesarean section during the first and second stages. Differential effects of oxytocin augmentation depending on dilation at admission may suggest that admission at the early stage of labor is an indicator rather than a risk factor itself, but admission at the intermediate stage (2.5–3.5 cm) becomes a risk factor itself. Further research is needed to study this hypothesis.

Variation in referrals to secondary obstetrician-led care among primary midwifery care practices in the Netherlands: a nationwide cohort study. BMC Pregnancy Childbirth 2015; 15:42. [PMID: 25885706 PMCID: PMC4342018 DOI: 10.1186/s12884-015-0471-x] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2014] [Accepted: 02/06/2015] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The primary aim of this study was to describe the variation in intrapartum referral rates in midwifery practices in the Netherlands. Secondly, we wanted to explore the association between the practice referral rate and a woman's chance of an instrumental birth (caesarean section or vaginal instrumental birth). METHODS We performed an observational study, using the Dutch national perinatal database. Low risk births in all primary care midwifery practices over the period 2008-2010 were selected. Intrapartum referral rates were calculated. The referral rate among nulliparous women was used to divide the practices in three tertile groups. In a multilevel logistic regression analysis the association between the referral rate and the chance of an instrumental birth was examined. RESULTS The intrapartum referral rate varied from 9.7 to 63.7 percent (mean 37.8; SD 7.0), and for nulliparous women from 13.8 to 78.1 percent (mean 56.8; SD 8.4). The variation occurred predominantly in non-urgent referrals in the first stage of labour. In the practices in the lowest tertile group more nulliparous women had a spontaneous vaginal birth compared to the middle and highest tertile group (T1: 77.3%, T2:73.5%, T3: 72.0%). For multiparous women the spontaneous vaginal birth rate was 97%. Compared to the lowest tertile group the odds ratios for nulliparous women for an instrumental birth were 1.22 (CI 1.16-1.31) and 1.33 (CI 1.25-1.41) in the middle and high tertile groups. This association was no longer significant after controlling for obstetric interventions (pain relief or augmentation). CONCLUSIONS The wide variation between referral rates may not be explained by medical factors or client characteristics alone. A high intrapartum referral rate in a midwifery practice is associated with an increased chance of an instrumental birth for nulliparous women, which is mediated by the increased use of obstetric interventions. Midwives should critically evaluate their referral behaviour. A high referral rate may indicate that more interventions are applied than necessary. This may lead to a lower chance of a spontaneous vaginal birth and a higher risk on a PPH. However, a low referral rate should not be achieved at the cost of perinatal safety.

Abstract
BACKGROUND Prolonged labour very often causes suffering from difficulties that may have lifelong implications. This study aimed to explore the prevalence and treatment of prolonged labour and to compare birth outcome and women's experiences of prolonged and normal labour. METHOD Women with spontaneous onset of labour, living in a Swedish county, were recruited two months after birth, to a cross-sectional study. Women (n = 829) completed a questionnaire that investigated socio-demographic and obstetric background, birth outcome and women's feelings and experiences of birth. The prevalence of prolonged labour, as defined by a documented ICD-code and inspection of partogram was calculated. Four groups were identified; women with prolonged labour as identified by documented ICD-codes or by partogram inspection but no ICD-code; women with normal labour augmented with oxytocin or not. RESULTS Every fifth woman experienced a prolonged labour. The prevalence with the documented ICD-code was (13%) and without ICD-code but positive partogram was (8%). Seven percent of women with prolonged labour were not treated with oxytocin. Approximately one in three women (28%) received oxytocin augmentation despite having no evidence of prolonged labour. The length of labour differed between the four groups of women, from 7 to 23 hours.Women with a prolonged labour had a negative birth experience more often (13%) than did women who had a normal labour (3%) (P <0.00). The factors that contributed most strongly to a negative birth experience in women with prolonged labour were emergency Caesarean section (OR 9.0, 95% CI 1.2-3.0) and to strongly agree with the following statement 'My birth experience made me decide not to have any more children' (OR 41.3, 95% CI 4.9-349.6). The factors that contributed most strongly to a negative birth experience in women with normal labour were less agreement with the statement 'It was exiting to give birth' (OR 0.13, 95% CI 0.34-0.5). CONCLUSIONS There is need for increased clinical skill in identification and classification of prolonged labour, in order to improve care for all women and their experiences of birthing processes regardless whether they experience a prolonged labour or not.

Abstract
BACKGROUND Approximately 15% of women have caesarean sections (CS) and while the rate varies, the number is increasing in many countries. This is of concern because higher CS rates do not confer additional health gain but may adversely affect maternal health and have implications for future pregnancies. Active management of labour has been proposed as a means of reducing CS rates. This refers to a package of care including strict diagnosis of labour, routine amniotomy, oxytocin for slow progress and one-to-one support in labour. OBJECTIVES To determine whether active management of labour reduces CS rates in low-risk women and improves satisfaction. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (16 April 2013). SELECTION CRITERIA Randomised controlled trials comparing low-risk women receiving a predefined package of care (active management) with women receiving routine (variable) care. Trials where slow progress had been diagnosed before entry into the trial were excluded. DATA COLLECTION AND ANALYSIS At least two review authors extracted data. We assessed included studies for risk of bias. MAIN RESULTS We included seven trials, with a total of 5390 women. The quality of studies was mixed. The CS rate was slightly lower in the active management group compared with the group that received routine care, but this difference did not reach statistical significance (RR 0.88, 95% CI 0.77 to 1.01). However, in one study there was a large number of post-randomisation exclusions. On excluding this study, CS rates in the active management group were statistically significantly lower than in the routine care group (RR 0.77 95% CI 0.63 to 0.94). More women in the active management group had labours lasting less than 12 hours, but there was wide variation in length of labour within and between trials. There were no differences between groups in use of analgesia, rates of assisted vaginal deliveries or maternal or neonatal complications. Only one trial examined maternal satisfaction; the majority of women (over 75%) in both groups were very satisfied with care. AUTHORS' CONCLUSIONS Active management is associated with small reductions in the CS rate, but it is highly prescriptive and interventional. It is possible that some components of the active management package are more effective than others. Further work is required to determine the acceptability of active management to women in labour.
