Identification of maternal characteristics associated with the use of epidural analgesia

Chorioamnionitis and its association with neonatal and maternal adverse outcomes in women with and without epidural analgesia administration

OBJECTIVE

To evaluate neonatal fever and adverse maternal and neonatal outcomes in febrile laboring women and assess whether the time interval between epidural analgesia (EA) administration and chorioamnionitis is associated with these complications.

METHODS

A retrospective cohort study at a university affiliated medical center between 2003 and 2015. Included were women who underwent term vaginal delivery attempt and diagnosed with chorioamnionitis. The primary outcomes compared between febrile women with and without EA were neonatal fever and adverse neonatal and maternal outcomes. The association between time from EA to fever (<6, 6-12, >12 h) and maternal and neonatal complications was also assessed.

RESULTS

During the study period, 1,933 women with chorioamnionitis were assessed. Of them, 1,810 (93.6%) received EA prior to fever and 123 (6.4%) febrile parturients did not receive EA. Neonatal fever and other neonatal adverse outcomes were similar in the EA vs. non-EA group (2.2% vs. 0.8% and 2.7% vs. 4.9% (NS)), except for transient tachypnea of the newborn rates which were lower in the EA group (1.4% vs. 4.1%, p = 0.043). Maternal complications were similar, besides for higher rates of instrumental deliveries found in the EA group (24.0% vs. 5.7%, p < 0.001). Time between EA and fever onset was not associated with neonatal complications in logistic regression analysis.

CONCLUSION

Neonatal and maternal outcomes are similar in febrile laboring women with and without EA. The time interval between EA and onset of fever is not associated with increased rates of neonatal fever or adverse outcomes and should not affect the management of labor.

Epidural use among women with spontaneous onset of labour - an observational study using data from a cluster-randomised controlled trial

OBJECTIVE

To investigate whether the proportion of pregnant women who use epidural analgesia during birth differed between women registered at a maternity clinic randomised to Mindfetalness or to routine care.

DESIGN

An observational study including women born in Sweden with singleton pregnancies, with spontaneous onset of labour from 32 weeks' gestation. Data used from a cluster-randomised controlled trial applying the intention-to-treat principle in 67 maternity clinics where women were randomised to Mindfetalness or to routine care. ClinicalTrials.gov (NCT02865759).

INTERVENTIONS

Midwives were instructed to distribute a leaflet about Mindfetalness to pregnant women at 25 weeks' gestation. Mindfetalness is a self-assessment method for the woman to use to become familiar with the unborn baby's fetal movement pattern. When practising the method in third trimester, the women are instructed to daily lie down on their side, when the baby is awake, and focus on the movements' intensity, character and frequency (but not to count each movement).

FINDINGS

Of the 18 501 women with spontaneous onset of labour, 47 percent used epidural during birth. Epidural was used to a lower extent among women registered at a maternity clinic randomised to Mindfetalness than women in the routine-care group (46.2% versus 47.8%, RR 0.97, CI 0.94-1.00, p= 0.04). Epidural was more common among primiparous women, women younger than 35 years, those with educational levels below university, with BMI ≥25 and with a history of receiving psychiatric care or psychological treatment for mental illness.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Pregnant women who were informed about a self-assessment method, with the aim of becoming familiar with the unborn baby's fetal movement pattern, used epidural to a lower extent than women who were not informed about the method. Future studies are needed to investigate and understand the association between Mindfetalness and the reduced usage of epidural during birth.

Effects of different analgesic methods used for vaginal delivery on mothers and fetuses

Background/aim

Knowledge regarding pain relief during labor remains insufficient. We aimed to determine and compare the effectiveness and safety of epidural analgesia, combined spinal–epidural analgesia, and parenteral meperidine on both mothers and fetuses.

Materials and methods

This study was designed as an observational case-control study. We collected prospective data from patients whose labor pain management was conducted with meperidine in addition to retrospective cohort data of neuraxial methods; 138 patients were enrolled. Epidural analgesia group consisted of 68 patients, whereas combined spinal-epidural (CSE) analgesia group and meperidine group consisted of 50 and 20 patients, respectively. We compared the delivery patterns, labor durations, pain levels, side effects, maternal satisfaction levels, and neonatal outcomes of the various pain management methods.

Results

Patient demographics, duration of first, second, and third labor stages, and instrumental delivery rates were comparable among groups (P > 0.05). Cesarean section tended to be less frequent in the CSE group. In the meperidine group, visual analog scale (VAS) values and sedation were significantly higher (P < 0.001) and maternal satisfaction lower (P < 0.001). Hypotension tended to be more frequent in the meperidine group. APGAR scores at the 1st and 5th min were similar among the groups and between meperidine subgroups defined by three different administration times (<1 h, 1‒4 h, ≥4 h; P > 0.05).

Conclusion

Neuraxial methods had no effect on instrumental delivery rates. CSE represented a near significant risk reduction in cesarean section. Our results demonstrated that regional analgesia methods were reasonably safe for both mother and fetus, and regional analgesia methods resulted in greater maternal satisfaction and pain control compared to meperidine.

Factors promoting or inhibiting normal birth

BACKGROUND

In response to rising rates of medical intervention in birth, there has been increased international interest in promoting normal birth (without induction of labour, epidural/spinal/general anaesthesia, episiotomy, forceps/vacuum, or caesarean section). However, there is limited evidence for how best to achieve increased rates of normal birth. In this study we examined the role of modifiable and non-modifiable factors in experiencing a normal birth using retrospective, self-reported data.

METHODS

Women who gave birth over a four-month period in Queensland, Australia, were invited to complete a questionnaire about their preferences for and experiences of pregnancy, labour, birth, and postnatal care. Responses (N = 5840) were analysed using multiple logistic regression models to identify associations with four aspects of normal birth: onset of labour, use of anaesthesia, mode of birth, and use of episiotomy. The probability of normal birth was then estimated by combining these models.

RESULTS

Overall, 28.7% of women experienced a normal birth. Probability of a normal birth was reduced for women who were primiparous, had a history of caesarean, had a multiple pregnancy, were older, had a more advanced gestational age, experienced pregnancy-related health conditions (gestational diabetes, low-lying placenta, high blood pressure), had continuous electronic fetal monitoring during labour, and knew only some of their care providers for labour and birth. Women had a higher probability of normal birth if they lived outside major metropolitan areas, did not receive private obstetric care, had freedom of movement throughout labour, received continuity of care in labour and birth, did not have an augmented labour, or gave birth in a non-supine position.

CONCLUSIONS

Our findings highlight several relevant modifiable factors including mobility, monitoring, and care provision during labour and birth, for increasing normal birth opportunity. An important step forward in promoting normal birth is increasing awareness of such relationships through patient involvement in informed decision-making and implementation of this evidence in care guidelines.

Sense of coherence in pregnant and new mothers - A longitudinal study of a national cohort of Swedish speaking women

BACKGROUND

Previous research shows inconsistent results about the stability of SOC during the childbearing period, and few studies have focused on longitudinal measures. There are contradictory results regarding the association between SOC and birth outcome. The link between levels of SOC and parental stress needs to be further explored.

AIM

The aim of this study was to investigate changes in SOC from early pregnancy to one year after birth and associations with background characteristics, birth outcome and parental stress.

METHODS

A longitudinal survey of a national cohort of Swedish speaking women during 3 weeks in 1999-2000. Data were collected by questionnaires in early pregnancy, 2 months and 1 year after birth.

RESULTS

SOC increased from pregnancy to 2 months after birth but decreased 1 year after birth. SOC was associated with women's background characteristics, emotional wellbeing and attitudes, but not with labour outcome. Women with low SOC reported higher parental stress after one year.

CONCLUSION

Sense of coherence is not stable during the childbearing period and is associated with women's sociodemographic background, emotional health and attitudes, but not with reproductive history or birth outcome. Parental stress is negatively correlated with SOC, and some important characteristics are similar in women having low SOC and high parental stress. Identifying women with low SOC in early pregnancy could be a means to prevent later parental stress.

Efficacy and Effects of Parenteral Pethidine or Meptazinol and Regional Analgesia for Pain Relief during Delivery. A Comparative Observational Study

Background: Peripartum anesthesia may consist of parenteral opioids and/or regional analgesia. There is only limited data in the literature comparing both methods in daily obstetric practice. This observational study investigated the opioids pethidine and meptazinol as well as regional analgesics with regard to their administration, efficacy, side effects and subjective maternal satisfaction with therapy. The rates of secondary regional analgesia administration after administration of the respective opioid served as a means of evaluating treatment. Methods: This study collected data on pain management during vaginal delivery in a German university hospital over a twelve month period. Severity of pain was measured intrapartum using a numerical rating scale. Maternal, neonatal and delivery-related data were obtained postpartum from the clinical records and from the mothers using a questionnaire. Results: The study is based on data obtained from 449 deliveries. Pain relief achieved by the administration of pethidine and meptazinol was similarly low; maternal satisfaction with the respective therapy was high. Meptazinol was usually administered intravenously (83 % vs. 6 %; p < 0.001), repeatedly (27 % vs. 6 %; p < 0.001) and closer to the birth (1.9 ± 2.7 h vs. 2.6 ± 2.8 h; p < 0.05) compared to pethidine. Secondary regional analgesia was more common after the administration of pethidine (16 % vs. 8 %; p < 0.05). Regional analgesia resulted in greater pain relief compared to opioid therapy (78 % vs. 24 % after 30 min; p < 0.001) and was associated with longer times to delivery (7.6 ± 2.5 h vs. 5.7 ± 2.5 h; p < 0.001) and higher levels of maternal satisfaction with therapy (6.1 ± 1.2 vs. 4.8 ± 1.6 on a 7-point scale; p < 0.001). Conclusion: In daily clinical practice, meptazinol can be adapted more readily to changes during birth and requires less secondary analgesia. Regional neuraxial analgesia was found to be an efficacious and safe way of managing labor pain.

Sense of coherence among healthy Norwegian women in postnatal care: Dimensionality reliability and construct validity of the Orientation to Life Questionnaire

OBJECTIVE

Salutogenesis focuses on identifying the causes of health rather than the causes of illness, and in this way offers a health promotion framework for maternity services. The application of salutogenesis theory in empirical studies of healthy women in maternity care appears to be rare, and mostly incomplete. The objective of this study is to examine the psychometric properties of the Orientation to Life Questionnaire (OLQ) assessing sense of coherence (SOC) in a population of healthy Norwegian women during the postnatal period.

METHODS

Self-reported cross-sectional data were collected from 183 women six weeks into the postnatal period. The data were analysed by descriptive statistics and confirmative factor analysis.

RESULTS

Discriminant validity was supported by significant negative correlations between SOC, meaningfulness, comprehensibility, manageability, anxiety and depression. Inter-item consistency with Cronbach's alpha (0.62-0.87) and composite reliability (0.60-0.92) revealed acceptable to good values approving the reliability. The original one-dimensional concept of sense of coherence was confirmed in this study. However, in accordance with previous research, some misspecifications in reference to correlated error variances between the items OLQ2 and OLQ3 were discovered.

CONCLUSION

This study lends support to the original one-dimensional construct of sense of coherence, and sheds more light upon the troublesome pair of items OLQ2-OLQ3. Further studies are required. However, based on our results, a rewording or deletion of one of these two items seems necessary in order to achieve a reliable and valid instrument measuring SOC among healthy postnatal women.

Sense of coherence and women׳s birthing outcomes: A longitudinal survey

BACKGROUND

in Western countries, caesarean section rates are increasing at an alarming rate. This trend has implications for women׳s health and calls into question the use of pathogenesis to frame maternity services. The theory of salutogenesis offers an alternative as it focuses on health rather than illness. Sense of coherence (SOC), the cornerstone of salutogenesis, is a predictive indicator of health. This study aimed to explore associations between pregnant women׳s SOC, their birthing outcomes and factors associated with SOC changes.

METHODS

a longitudinal survey was conducted where women completed a questionnaire in the antenatal and postnatal period. Questionnaire one provided information on SOC scores, Edinburgh Postnatal Depression Scale (EPDS) scores, Support Behaviour Inventory (SBI) scores, pregnancy choices and demographics. Questionnaire two provided information on SOC scores, EPDS scores and birthing outcomes.

FINDINGS

1074 women completed questionnaire one and 753 women completed questionnaire two. Compared to women with low antenatal SOC, women with high antenatal SOC were less likely to experience caesarean section (OR 0.437 95% CI 0.209-0.915) and more likely to experience assisted vaginal birth (AVB) (OR 3.108 95% CI 1.557-6.203). Higher birth satisfaction, higher antenatal EPDS scores and lower antenatal SOC were associated with an increase in SOC. Epidural, AVB and decreased birth satisfaction were associated with a decrease in SOC.

CONCLUSION

high sense of coherence in pregnant women is associated with half the likelihood of caesarean section compared to women with low sense of coherence. Women׳s sense of coherence is raised and lowered by degree of satisfaction with their births and lowered by some labour interventions.

Sense of coherence and childbearing choices: A cross sectional survey

BACKGROUND

as concern for increasing rates of caesarean section and interventions in childbirth in Western countries mounts, the utility of the risk approach (inherent in the biomedical model of maternity care) is called into question. The theory of salutogenesis offers an alternative as it focuses on the causes of health rather than the causes of illness. Sense of coherence (SOC), the cornerstone of salutogenic theory, is a predictive indicator of health. We hypothesised that there is a relationship between a woman's SOC and the childbirth choices she makes in pregnancy.

METHODS

the study aims to investigate the relationship between SOC and women's pregnancy and anticipated labour choices. A cross sectional survey was conducted where eligible women completed a questionnaire that provided information on SOC scores, Edinburgh Postnatal Depression (EPDS) scores, Support Behaviour Inventory (SBI) scores, pregnancy choices and demographics.

FINDINGS

1074 pregnant women completed the study. Compared to women with low SOC, women with high SOC were older, were less likely to identify pregnancy conditions, had lower EPDS scores and higher SBI scores. SOC was not associated with women's pregnancy choices.

CONCLUSION

this study relates SOC to physical and emotional health in pregnancy as women with high SOC were less likely to identify pregnancy conditions, had less depressive symptoms and perceived higher levels of support compared to women with low SOC. Interestingly, SOC was not associated with pregnancy choices known to increase normal birth rates. More research is required to explore the relationship between SOC and women's birthing outcomes.

The relationship between childbirth self-efficacy and aspects of well-being, birth interventions and birth outcomes

OBJECTIVE

this study aimed to examine how women׳s childbirth self-efficacy beliefs relate to aspects of well-being during the third trimester of pregnancy and whether there was any association between childbirth self-efficacy and obstetric factors.

DESIGN

a cross-sectional design was used. The data was obtained through the distribution of a composite questionnaire and antenatal and birth records.

SETTING

data were recruited from antenatal health-care clinics in Halland, Sweden.

PARTICIPANTS

a consecutive sample of 406 pregnant women was recruited at the end of pregnancy at gestational weeks of 35-42.

MEASUREMENTS

five different measures were used; the Swedish version of Childbirth Self-Efficacy Inventory, the Wijma Delivery Expectancy/Experience Questionnaire, the Sense of Coherence Questionnaire, the Maternity Social Support Scale and finally the Profile of Mood States.

FINDINGS

results showed that childbirth self-efficacy was correlated with positive dimensions as vigour, sense of coherence and maternal support and negatively correlated with previous mental illness, negative mood states and fear of childbirth. Women who reported high childbirth self-efficacy had less epidural analgesia during childbirth, compared to women with low self-efficacy.

KEY CONCLUSIONS

this study highlights that childbirth self-efficacy is a positive dimension that interplays with other aspects and contributes to well-being during pregnancy and thereby, acts as an asset in the context of childbirth.

Back to normal: A retrospective, cross-sectional study of the multi-factorial determinants of normal birth in Queensland, Australia

BACKGROUND

currently, care providers and policy-makers internationally are working to promote normal birth. In Australia, such initiatives are being implemented without any evidence of the prevalence or determinants of normal birth as a multidimensional construct. This study aimed to better understand the determinants of normal birth (defined as without induction of labour, epidural/spinal/general anaesthesia, forceps/vacuum, caesarean birth, or episiotomy) using secondary analyses of data from a population survey of women in Queensland, Australia.

METHODS

women who birthed in Queensland during a two-week period in 2009 were mailed a survey approximately three months after birth. Women (n=772) provided retrospective data on their pregnancy, labour and birth preferences and experiences, socio-demographic characteristics, and reproductive history. A series of logistic regressions were conducted to determine factors associated with having labour, having a vaginal birth, and having a normal birth.

FINDINGS

overall, 81.9% of women had labour, 66.4% had a vaginal birth, and 29.6% had a normal birth. After adjusting for other significant factors, women had significantly higher odds of having labour if they birthed in a public hospital and had a pre-existing preference for a vaginal birth. Of women who had labour, 80.8% had a vaginal birth. Women who had labour had significantly higher odds of having a vaginal birth if they attended antenatal classes, did not have continuous fetal monitoring, felt able to 'take their time' in labour, and had a pre-existing preference for a vaginal birth. Of women who had a vaginal birth, 44.7% had a normal birth. Women who had a vaginal birth had significantly higher odds of having a normal birth if they birthed in a public hospital, birthed outside regular business hours, had mobility in labour, did not have continuous fetal monitoring, and were non-supine during birth.

CONCLUSIONS

these findings provide a strong foundation on which to base resources aimed at increasing informed decision-making for maternity care consumers, providers, and policy-makers alike. Research to evaluate the impact of modifying key clinical practices (e.g., supporting women׳s mobility during labour, facilitating non-supine positioning during birth) on the likelihood of a normal birth is an important next step.

Promoting a normal birth and a positive birth experience - Norwegian women's perspectives

OBJECTIVE

the aim of this study is to gain a deeper understanding of a woman's internal factors and factors in her environment that are important for a normal birth and a positive birth experience.

DESIGN/SETTING

a qualitative approach was selected for data collection, and the data presented are derived from in-depth interviews. Twelve healthy first time Norwegian mothers, aged 22-34, with a normal childbirth and a positive birth experience were interviewed five to six weeks after giving birth. All participants had given birth at a maternity unit, where 4000 births take place per year. The transcribed interviews were analysed through systematic text condensation.

FINDINGS

the findings included two main themes: safe environment and emotional strength. Stability in everyday life and close relationships provided the women with the safe environment they needed. The women had a positive attitude to childbirth and they had all previously developed coping strategies. They highlighted that these acquired coping strategies contributed to higher emotional strength and a positive birth experience.

CONCLUSIONS

the women experienced that a safe environment and network contributed to a sense of trust and emotional strength, which were positive factors promoting a normal birth and a positive birth experience. The women had a positive attitude towards the birth and used acquired coping strategies to deal with it, which in turn led to a positive birth experience. The natural vision the women had in connection with childbirth was part of their antenatal preparation, which also contributed to a positive experience of childbirth.

Does bupivacaine and fentanyl combination for epidural analgesia shorten the duration of labour?

In this study we aimed to explore the effects of epidural analgesia achieved by a combination of low-dose bupivacaine and fentanyl infused through an epidural catheter on mother, foetus and labour process in nulliparous at-term pregnant women during vaginal delivery. This study was designed in a prospective, randomised controlled manner. Epidural analgesia was achieved in 50 nulliparous women. Fifty nulliparous women did not undergo epidural analgesia procedure. The duration of the first stage of labour was significantly shortened, while the second stage was significantly lengthened in pregnant women who underwent epidural analgesia (p < 0.05). In conclusion, starting epidural analgesia application during the active phase of the first stage of labour may shorten the duration of the first stage compared with the group of nulliparous women not undergoing epidural analgesia. The factor that has an impact on this may be the addition of fentanyl to bupivacaine used for epidural analgesia.

Antenatal fear of childbirth and sense of coherence among healthy pregnant women in Japan: a cross-sectional study

While antenatal fear of childbirth (FOC) has been associated with many psychosocial variables, few studies have focused on individual stress resiliency. Sense of coherence (SOC) is one of the essential components of individual stress resiliency. This study investigates the relationship between antenatal FOC and SOC in Japanese healthy pregnant women. Self-reported questionnaires were distributed to 240 women at 37 gestational weeks at an obstetric clinic in Tokyo, Japan. Structural regression modeling was conducted to identify the causal relationships between FOC and SOC. The non-recursive model showed significant acceptance of fit (chi-square value/degree of freedom = 1.72, comparative fit index = 0.97, and root mean square error of approximation = 0.05). The model identified SOC as a direct cause of FOC (β = -0.89, p < 0.001), not a reflection of FOC. We found that SOC was negatively linked with antenatal fear of childbirth. High SOC works as a resiliency factor that helps pregnant women cope with the stress of their upcoming childbirth and reduces FOC.

Sense of Coherence and Childbearing: A Scoping Review of the Literature

OBJECTIVE: To undertake a scoping review of the literature to understand how a woman’s sense of coherence (SOC) score affects her childbearing.

METHOD: Ovid MEDLINE, CINAHL, Cochrane, and Web of Science databases were searched to identify articles published in English from 2000 to 2014 using combinations of specified search terms. Included articles were assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Critical Appraisal Skills Programme.

FINDINGS: This scoping review identified 15 studies focusing on SOC scores and childbearing. Childbearing women with strong SOC were less likely to smoke and more likely to seek out useful support compared to women with low SOC. Women with strong SOC demonstrated increased emotional health, experiencing less depression, anxiety, stress, and posttraumatic stress disorder. Women with strong SOC were more likely to experience uncomplicated birth and birth at home, identify normal birth as their preferred birth option in pregnancy and identify a desire to avoid epidural anesthesia in labor compared to women with low SOC.

CONCLUSION: This scoping review of the literature identified significant associations between strong SOC and positive childbearing, including increased emotional health, improved health behaviors, and increased normal birth choices and outcomes.

Managing the pain of labour: factors associated with the use of labour pain management for pregnant Australian women

BACKGROUND

Despite high rates of women's use of intrapartum pain management techniques, little is known about the factors that influence such use.

OBJECTIVE

Examine the determinants associated with women's use of labour pain management.

DESIGN

Cross-sectional survey of a substudy of women from the 'young' cohort of the Australian Longitudinal Study of Women's Health (ALSWH).

SETTING AND PARTICIPANTS

Women aged 31-35 years who identified as being pregnant or recently given birth in the 2009 ALSWH survey (n = 2445) were recruited for the substudy. The substudy survey was completed by 1835 women (RR = 79.2%).

MAIN VARIABLES STUDIED

Determinants examined included pregnancy health and maternity care [including complementary and alternative medicine (CAM)] for their most recent pregnancy and any previous pregnancies. Participants' attitudes and beliefs related to both CAM and maternity care were also included in the analysis.

MAIN OUTCOME MEASURES

The outcome measures examined were the use of both pharmacological and non-pharmacological pain management techniques (NPMT).

RESULTS

Differences were seen in the effects of demographics, health service utilization, health status, use of CAM, and attitudes and beliefs upon use of intrapartum pain management techniques across all categories. The only variable that was identified as a determinant for use of all types of pain management techniques was a previous caesarean section (CS).

DISCUSSION AND CONCLUSIONS

The effect of key determinants on women's use of pain management techniques differs significantly, and, other than CS, no one determinant is clearly influential in the use of all pain management options.
