Effect of maternal birth positions on duration of second stage of labor: systematic review and meta-analysis

Birthing positions and mother`s satisfaction with childbirth: a cross-sectional study on the relevance of self determination

INTRODUCTION

Considering the inconclusive evidence regarding the clinical benefits of specific birthing positions, emphasis has been placed on adhering to women's preferences during the second stage of labour. Therefore, the present study aimed to assess the association between birthing position, the freedom to choose a birth position during the second stage of labour, and women's subjective satisfaction with childbirth.

METHODS

We performed a cross-sectional survey of women 8 or 12 months after a vaginal birth in a hospital. The women were recruited via two cooperating health insurance companies. Multivariate analyses were conducted to assess the strength of the association between birthing position and maternal satisfaction with childbirth, with a particular focus on interactions with self-determination.

RESULTS

In total, the data from 761 women were analysed. The supine position was the most frequently reported birthing position in the second stage of labour at 77.5%. Notably, 39.0% and 30.5% of the women who gave birth in the dorsal and lateral supine positions, respectively, stated that the birth position was not chosen voluntarily. The regression models show a significant negative association between supine birthing position and satisfaction with childbirth, which is significantly related to self-determination. The most common reason for the adoption of a specific birthing position was instructions from medical staff.

DISCUSSION

The data provide insight into the perceived satisfaction with childbirth depending on the birthing position, whereby the relevance of self-determination is particularly evident. At the same time, self-determination is often not given, which is associated with reduced birth satisfaction.

The understanding of dynamic birth positions for women in labor and childbirth - A hybrid concept analysis

PROBLEM AND BACKGROUND

The assessment of advantages and drawbacks associated with varying birthing positions has predominantly centered around medical or technical considerations and few studies have accounted for a woman's ability to attune to her bodily instincts during labor and birth. The objective of this study was to define the concept of dynamic birth positions and its significance within the birthing process.

METHODS

This hybrid concept analysis consisted of three phases: theoretical, fieldwork, and analytical. Science Direct, PubMed and Google Scholar were searched with related terms in the theoretical phase. In the fieldwork phase, seven professionals and six mothers with the experience of dynamic birth positions were interviewed. After each interview, qualitative content analysis was conducted. During the final phase, descriptions and themes from the first two phases were combined.

RESULTS

In the theoretical phase, the definition of dynamic birth positions included descriptions answering the Who, What, When, Where, and Why questions. In the fieldwork phase, the results present two distinct categories that define dynamic birth positions: "Women's choice, women's power" and "A flow between rest and activity." The final analysis phase of this study indicated that dynamic birth positioning is characterized by the organic progression through a variety of postures that seamlessly merge rest and activity throughout the labor and birthing process, guided by the woman's individual preferences.

CONCLUSIONS

The definition of dynamic birth positions redefines birth as an evolving, dynamic journey characterized by a fluid interplay of movements and moments of rest, transcending conventional fixation on static positions.

A qualitative descriptive training needs analysis of midwives perceived continuous professional development in providing intranatal respectful maternal care

BACKGROUND

The Vietnam midwifery report acknowledges that while health services are available in Vietnam, there is growing need to increase levels of respectful maternal care provided to women in labour.

OBJECTIVE

In conjunction with newborns Vietnam charity, our objective was to assess the perceived continuous professional development needs of midwives working in Vietnam to inform development of an intranatal respectful maternal care education resource.

METHOD

A qualitative exploratory descriptive method was used to conduct a training needs analysis, which identified perceived education requirements of midwives in Vietnam in relation to providing respectful maternal care.

PARTICIPANTS

A convenience sample of midwives (n = 49) participated in the study.

DATA-COLLECTION

Eight on-line focus groups were carried out in four hospitals (maternity units) across Vietnam using WebEx, with the interview schedule informed by the World Health Organization guide for delivering intrapartum care for a positive birth experience.

DATA-ANALYSIS

Data were transcribed into English and analysed using the 6-steps of thematic analysis outlined by Braun and Clark.

FINDINGS

Three themes and 9 sub-themes were developed from the data. The first theme addressed aspects that contribute towards creating a positive birth experience; the second theme observed barriers to changing practice; and the third theme noted that there are a variety of preferred teaching methods.

CONCLUSIONS

In response to the training needs analysis, a respectful maternal care education resource has been designed to transform selected areas of intranatal care in Vietnam. Integrating the respectful maternal care educational resource into midwives' continuous professional development in Vietnam is intended to increase women's rights to have safe childbirth, which accommodates choice and control, and promotes a positive birth experience.

RECOMMENDATIONS FOR PRACTICE

Post-completion and evaluation, we hope that the intranatal respectful maternal care educational resource will be rolled out to all practising midwives in Vietnam.

The prevention of perineal trauma during vaginal birth

Perineal trauma after vaginal birth is common, with approximately 9 of 10 women being affected. Second-degree perineal tears are twice as likely to occur in primiparous births, with a incidence of 40%. The incidence of obstetrical anal sphincter injury is approximately 3%, with a significantly higher rate in primiparous than in multiparous women (6% vs 2%). Obstetrical anal sphincter injury is a significant risk factor for the development of anal incontinence, with approximately 10% of women developing symptoms within a year following vaginal birth. Obstetrical anal sphincter injuries have significant medicolegal implications and contribute greatly to healthcare costs. For example, in 2013 and 2014, the economic burden of obstetrical anal sphincter injuries in the United Kingdom ranged between £3.7 million (with assisted vaginal birth) and £9.8 million (with spontaneous vaginal birth). In the United States, complications associated with trauma to the perineum incurred costs of approximately $83 million between 2007 and 2011. It is therefore crucial to focus on improvements in clinical care to reduce this risk and minimize the development of perineal trauma, particularly obstetrical anal sphincter injuries. Identification of risk factors allows modification of obstetrical practice with the aim of reducing the rate of perineal trauma and its attendant associated morbidity. Risk factors associated with second-degree perineal trauma include increased fetal birthweight, operative vaginal birth, prolonged second stage of labor, maternal birth position, and advanced maternal age. With obstetrical anal sphincter injury, risk factors include induction of labor, augmentation of labor, epidural, increased fetal birthweight, fetal malposition (occiput posterior), midline episiotomy, operative vaginal birth, Asian ethnicity, and primiparity. Obstetrical practice can be modified both antenatally and intrapartum. The evidence suggests that in the antenatal period, perineal massage can be commenced in the third trimester of pregnancy to increase muscle elasticity and allow stretching of the perineum during birth, thereby reducing the risk of tearing or need for episiotomy. With regard to the intrapartum period, there is a growing body of evidence from the United Kingdom, Norway, and Denmark suggesting that the implementation of quality improvement initiatives including the training of clinicians in manual perineal protection and mediolateral episiotomy can reduce the incidence of obstetrical anal sphincter injury. With episiotomy, the International Federation of Gynecology and Obstetrics recommends restrictive rather than routine use of episiotomy. This is particularly the case with unassisted vaginal births. However, there is a role for episiotomy, specifically mediolateral or lateral, with assisted vaginal births. This is specifically the case with nulliparous vacuum and forceps births, given that the use of mediolateral or lateral episiotomy has been shown to significantly reduce the incidence of obstetrical anal sphincter injury in these groups by 43% and 68%, respectively. However, the complications associated with episiotomy including perineal pain, dyspareunia, and sexual dysfunction should be acknowledged. Despite considerable research, interventions for reducing the risk of perineal trauma remain a subject of controversy. In this review article, we present the available data on the prevention of perineal trauma by describing the risk factors associated with perineal trauma and interventions that can be implemented to prevent perineal trauma, in particular obstetrical anal sphincter injury.

Factors Influencing Duration of Breastfeeding: Insights from a Prospective Study of Maternal Health Literacy and Obstetric Practices

Numerous factors concerning early breastfeeding abandonment have been described, including health literacy (HL). This study's objective was to analyze factors related to early breastfeeding abandonment (<6 months). This prospective multicentric study examined the duration of breastfeeding at 6 months postpartum and was conducted in four different regions of Spain from January 2021 to January 2023. A total of 275 women participated in this study, which focused on maternal HL and obstetric practices. A decrease in the breastfeeding rate was observed from hospital discharge (n = 224, 81.5%) to the sixth month postpartum (n = 117, 42.5%). A Cox regression analysis revealed that inadequate HL levels, lack of mobilization during labour, and induced labour were significantly associated with early breastfeeding cessation (p = 0.022, p = 0.019, and p = 0.010, respectively). The results highlight that women with adequate HL had a 32% lower risk of early breastfeeding abandonment. In comparison, mobilization during labour and induction of labour were linked to a 32.4% reduction and a 53.8% increase in this risk, respectively. These findings emphasize the importance of considering obstetric and HL factors when addressing the breastfeeding duration, indicating opportunities for educational and perinatal care interventions.

Analysis of Maternal Positions during the Dilation and Expulsive Phase and Their Relationship with Perineal Injuries in Eutocic Deliveries Attended by Midwives

This cross-sectional descriptive study aimed to analyze the relationship between maternal positions during the expulsion phase and perineal outcomes in 367 eutocic births attended by midwives or midwifery residents at a public hospital in northern Spain in 2018. A total of 94.3% of women opted for horizontal positions. Limited sacral retroversion was observed in 71.7%, potentially influencing perineal outcomes. A low incidence of tears indicated effective management during the expulsive phase, with an episiotomy rate of 15.3%, which was slightly above the 15% standard. Primiparity and maternal age were identified as risk factors associated with episiotomy. Additionally, sacral mobilization and vertical positions during delivery were significantly related to fewer perineal injuries, suggesting benefits for both mother and newborn. The correlation between maternal positions and the need for epidural analgesia highlighted the importance of considering these in pain management during childbirth. Despite limitations, the study provides valuable insight into obstetric practices and advocates for a woman-centered approach that respects autonomy during childbirth. Further research is needed to explore biomechanical parameters and enhance childbirth experiences.

Methods of induction and augmentation of labor in a freestanding birth center: a cross-sectional study

OBJECTIVE

To describe and analyze the use of methods of induction and augmentation of labor in a freestanding birth center (FBC).

METHOD

Cross-sectional study carried out at a FBC located in São Paulo (SP), with all women booked from 2011 to 2021 (n = 3,397).

RESULTS

The majority of women (61.3%) did not receive any method. The methods were used alone or in combination (traditional Chinese medicine, massage, castor oil, stimulating tea, amniotomy, and oxytocin). Traditional Chinese medicine (acupuncture, acupressure, and moxa) was the most used method (14.7%) and oxytocin was the least frequent (5.1%). The longer the water breaking time, the greater the number of methods used (p < 0.001). Amniotomy was associated with maternal transfers (p < 0.001).

CONCLUSION

Induction and augmentation of labor were strictly adopted. The use of natural or non-pharmacological methods prevailed. Robust clinical studies are needed to prove the effectiveness of non-pharmacological methods of stimulation of childbirth, in addition to strategies for their implementation in other childbirth care services, to really prove the effectiveness of non-pharmacological methods in the parturition process, that is, in labor and birth.

Vacuum-assisted birth in maternal lateral posture versus lithotomy. A simulation study

OBJECTIVE

Maternal lateral postures provide advantages during childbirth. This study aims to investigate the feasibility of assisting vacuum births in maternal lateral postures in a simulation model.

STUDY DESIGN

In a simulation model, four obstetricians and four medical students were randomly allocated to perform vacuum-assisted births first in maternal lateral posture or lithotomy. A modification of Aldo Vacca's 5-step technique was developed to assist vacuum-assisted births in lateral posture. The lateral distance, vertical distance, and distance from the cup center to the flexion point were measured for every placement of the cup.

RESULTS AND CONCLUSIONS

A total of 128 vacuum-assisted births were performed. The mean distance to the flexion point was 1.15 ± 0.71 cm for the lithotomy posture and 1.31 ± 0.82 cm for the lateral posture (P = 0.127). There were no statistically significant differences in vacuum extractor cup placement accuracy based on maternal posture. Performing vacuum-assisted births in maternal lateral posture is feasible in a simulation model. The technique is easy to learn, and the differences in cup placement between the lateral and lithotomy postures are small.

A virtual simulation-based training program on birthing positions: a randomized controlled trial

BACKGROUND

Restricting parturient women in healthcare facilities from choosing positions that provide the greatest comfort and benefit during labor is a global barrier. Several complex factors, including caregiver preference and medical intervention, shape the limitation. Therefore, a practical need exists to train midwives on the knowledge and skills to change this condition.

METHODS

The study used a parallel, single-blind, randomized controlled trial at a provincial maternity and child health hospital in Fujian, China, from June 1 to December 31, 2019. The midwives in a birth suite were selected and randomly enrolled in a one-month simulation-based hybrid training or face-to-face teaching in September 2019. The four-level Kirkpatrick's model, including reaction, learning, behavior, and results, was used to evaluate training effects before and after the program. Data were analyzed with SPSS 25.0 using Student's t-test, Spearman's correlation test, Mann-Whitney U test, Wilcoxon signed-rank test, and chi-square test analysis of variance. The significance level was set at p < 0.05.

RESULTS

Forty-two midwives were initially randomized to either the virtual simulation group or the face-to-face group. One midwife was excluded from the analysis due to intervention discontinuation, resulting in a final analysis of 41 midwives (n1 = 21, n2 = 20). Post-intervention, the virtual simulation group exhibited higher satisfaction and learning effects compared to the face-to-face group, while the rate of perineal incision in primiparas was lower (p<0.05). No significant changes or differences were observed in self-rated behavior between the two groups (p>0.05). The virtual simulation group demonstrated an increase in non-supine birth rate (p = 0.030) and a decrease in perineal incision rate among primiparas compared to pre-intervention (p = 0.035). Moreover, knowledge performance was associated with the duration of virtual simulation (r = 0.664, p = 0.001).

CONCLUSIONS

Virtual simulation is a fascinating innovation that enables midwives to develop birthing positions without practicing on real pregnant women and is one solution to achieve work competency within a shortened training period.

Costs and intermediate outcomes for the implementation of evidence-based practices of midwifery under a MIDWIZE framework in an urban health facility in Nairobi, Kenya

BACKGROUND

Three evidence-based midwife-led care practices: dynamic birth positions (DBP), immediate skin-to-skin contact (SSC) with zero separation between mother and newborn, and delayed cord clamping (DCC), were implemented in four sub-Saharan African countries after an internet-based capacity building program for midwifery leadership in quality improvement (QI). Knowledge on costs of this QI initiative can inform resource mobilization for scale up and sustainability.

METHODS

We estimated the costs and intermediate outcomes from the implementation of the three evidence-based practices under the midwife-led care (MIDWIZE) framework in a single facility in Kenya through a pre- and post-test implementation design. Daily observations for the level of practice on DBP, SSC and DCC was done at baseline for 1 week and continued during the 11 weeks of the training intervention. Three cost scenarios from the health facility perspective included: scenario 1; staff participation time costs ($515 USD), scenario 2; staff participation time costs plus hired trainer time costs, training material and logistical costs ($1318 USD) and scenario 3; staff participation time costs plus total program costs for the head trainer as the QI leader from the capacity building midwifery program ($8548 USD).

RESULTS

At baseline, the level of DBP and SSC practices per the guidelines was at 0 % while that of DCC was at 80 %. After 11 weeks, we observed an adoption of DBP practice of 36 % (N = 111 births), SSC practice of 79 % (N = 241 births), and no change in DCC practice. Major cost driver(s) were midwives' participation time costs (56 %) for scenario 1 (collaborative), trainers' material and logistic costs (55 %) in scenario 2(collaborative) and capacity building program costs for the trainer (QI lead) (94 %) in scenario 3 (programmatic). Costs per intermediate outcome were $2.3 USD per birth and $0.5 USD per birth adopting DBP and SSC respectively in Scenario 1; $6.0 USD per birth adopting DBP and $1.4 USD per birth adopting SSC in Scenario 2; $38.5 USD per birth adopting DBP and $8.8 USD per birth adopting SSC in scenario 3. The average hourly wage of the facility midwife was $4.7 USD.

CONCLUSION

Improving adoption of DBP and SSC practices can be done at reasonable facility costs under a collaborative MIDWIZE QI approach. In a programmatic approach, higher facility costs would be needed. This can inform resource mobilization for future QI in similar resource-constrained settings.

Correlation between bituberous diameter and mode of delivery in a cohort of low-risk nulliparous women

OBJECTIVE

The aim our study was to evaluate the association between the antepartum clinical measurement of the Bituberous Diameter (BTD) and the occurrence of unplanned obstetrical intervention (UOI) due to labor dystocia, including either operative vaginal delivery or caesarean section in a cohort of low-risk, nulliparous at term.

DESIGN

Retrospective analysis of prospectively collected data.

SETTING

Tertiary maternity care.

INTERVENTIONS

With the women lying in lithotomic the distance between two ischial tuberosities was assessed using a tape measure during the routine antenatal booking between 37 and 38 weeks of gestation.

MEASUREMENTS AND FINDINGS

Overall, 116 patient were included, and of these 23(19.8%) were submitted to an UOI due to labor dystocia. Compared to women that had a spontaneous vaginal delivery, women submitted to an UOI had a shorter BTD (8.25 + 0.843 vs 9.60 + 1.12, p < 0.001), a higher frequency of epidural analgesia (21/23 or 91.3% vs 50/93 or 53.8%; p = 0.002) and of augmentation of labor (14/23 or 60.9% vs 19/93 or 20.4%; p < 0.001) as well as a longer first [455 (IQR 142-455 min vs 293 (IQR 142-455) min] and second stages of labor [129 (IQR 85-155) min vs 51 (IQR 27-78) min]. Multivariable logistic regression showed that the BTD (aOR 0.16, 95% CI 0.04-0.60; p = 0.007) and the length of the second stage of labor (aOR 6.83, 95% CI 2.10-22.23; p = 0.001) were independently associated with UOI. When evaluating the diagnostic accuracy of the BTD for the prediction of UOI due to labor dystocia, the BTD showed an AUC of 0.82 (95 %CI 0.73-0.91; p < 0.001) with an optimal cut-off value of 8.6 cm (78.3% (95 %CI 56.3-92.5) sensitivity, 77.4% (95 %CI 67.6-85.4) specificity, 46.2% (95% CI 30.1-62.8) PPV, 93.5% (95% CI 85.5-97.9) NPV, 3.5 (95% CI 2.3-5.4) positive LR, and 0.28 (95% CI 0.13-0.61) negative LR. A significant inverse correlation between the length of the second stage of labour and the BTD in patients that had a vaginal delivery was also demonstrated (Spearman's rho = -0.24, p = 0.01).

KEY CONCLUSIONS

Our study suggests that antepartum clinical assessment of the BTD might be used as a reliable predictor of UOI due to labor dystocia in low-risk, nulliparous women at term gestation.

IMPLICATIONS FOR PRACTICE

Antenatal identification of women at higher risk for labor dystocia might trigger some interventions during the second stage of labor, such as maternal position shifting, to increase the pelvic capacity and potentially improve outcomes or might prompt a referral of the patient to a district hospital prior to the onset of labor.

Intrapartum ultrasound in maternal lateral versus semi-recumbent posture. A repeated measures study

OBJECTIVE

This study aimed to assess whether intrapartum ultrasound (ITU) measurements in maternal lateral posture are superimposable to ITU measurements in semi-recumbent position.

STUDY DESIGN

A single-center, repeated measures design was used. Women in the second stage of labor were randomized to ITU first in semi-recumbent followed by ITU in side-lying posture without and with contraction, or inversely. The angle of progression (AOP) and the head-perineum distance (HPD) between contractions (AOP1 and HPD1) and with contraction (AOP2 and HPD2) were measured in each maternal posture. The differences between AOP1 and AOP2 (dAOP), and between HPD1 and HPD2 (dHPD) were calculated.

RESULTS AND CONCLUSIONS

Forty-two women participated in the study. A generalized estimating equation model showed that AOP1 (-3.00°; 95 % CI -5.77 to -0.23; p = 0.03) and AOP2 (-4.14°; 95 % CI -7.20 to -1.08; p = 0.008) were lower in semi-recumbent compared to maternal lateral posture. HPD1 (+1.43 mm; 95 % CI 0.05-2.81; p = 0.042) and HPD2 (+1.53 mm; 95 % CI 0.17-2.89; p = 0.03) were higher in semi-recumbent position. Differences in the ITU measurements in maternal lateral posture compared to semi-recumbent position are small. Monitoring the second stage of labor with ITU in lateral maternal posture is possible.

Maternal position during the second stage of labor and maternal-neonatal outcomes in nulliparous women: a retrospective cohort study

BACKGROUND

The existing evidence is insufficient to draw conclusions about the association between maternal position in labor and obstetrical outcomes.

OBJECTIVE

This study aimed to evaluate the effects of different maternal positions during the second stage of labor among women with and those without epidural analgesia on important obstetrical outcomes including perineal damage.

STUDY DESIGN

In this retrospective cohort study, we collected data of women who delivered vaginally over a 2-year period. The associations between maternal and gestational characteristics and several obstetrical outcomes were analyzed. We considered perineal damage as the primary outcome. Secondary outcomes were the incidence of operative vaginal births, duration of fetal descent, intrapartum blood loss, and 1-minute and 5-minutes Apgar scores.

RESULTS

A total of 2240 nulliparous, at-term pregnancies were included. Of those, 76.9% gave birth in a supine position and 23.1% gave birth in alternative positions. The results showed that regardless of the use of epidural analgesia, nonsupine positions in the second stage of labor are associated with a significant reduction in the risk of both episiotomy and perineal damage to any degree (P<.0001) and to a reduction in the duration of fetal descent (Spearman rho, 9.17; confidence interval, 3.07-15.32; P=.003). No statistically significant differences were found in the 1-minute and 5-minutes Apgar score between the 2 groups.

CONCLUSION

Our results show that nonsupine positions in the second stage of labor and at the time of birth are associated with a significant increase in having an intact perineum and a reduction in any perineal trauma and in the need for an episiotomy regardless of the use of epidural analgesia.

[Good practices, interventions, and results: a comparative study between a birthing center and hospitals of the Brazilian Unified National Health System in the Southeastern Region, Brazil]

This study aims to compare obstetric care in a birthing center and in hospitals of the Brazilian Unified National Health System (SUS) considering good practices, interventions, and maternal and perinatal results in the Southeast Region of Brazil. A cross-sectional study was conducted with comparable retrospective data from two studies on labor and birth. A total of 1,515 puerperal women of usual risk of birthing centers and public hospitals in the Southeast region were included. Propensity score weighting was used to balance the groups according to the following covariates: age, skin-color, parity, membrane integrity, and cervix dilation at hospitalization. Logistic regressions were used to estimate odds ratios (OR) and 95% confidence intervals (95%CI) between the place of birth and outcomes. In birthing centers, compared to hospitals, the puerperal woman had a higher chance of having a companion (OR = 86.31; 95%CI: 29.65-251.29), eating or drinking (OR = 862.38; 95%CI: 120.20-6,187.33), walking around (OR = 7.56; 95%CI: 4.65-12.31), using non-pharmacological methods for pain relief (OR = 27.82; 95%CI: 17.05-45.40), being in an upright position (OR = 252.78; 95%CI: 150.60-423.33), and a lower chance of using oxytocin (OR = 0.22; 95%CI: 0.16-0.31), amniotomy (OR = 0.01; 95%CI: 0.01-0.04), episiotomy (OR = 0.01; 95%CI: 0.00-0.02), and Kristeller maneuvers (OR = 0.01; 95%CI: 0.00-0.02). Also, in birthing centers the newborn had a higher chance of exclusive breastfeeding (OR = 1.84; 95%CI: 1.16-2.90) and a lower chance of airway (OR = 0.24; 95%CI: 0.18-0.33) and gastric aspiration (OR = 0.15; 95%: 0.10-0.22). Thus, birthing centers offers a greater supply of good practices and fewer interventions in childbirth and birth care, with more safety and care without influence on the outcomes.

Factors associated with the occurrence of upright birth in Brazil

OBJECTIVE

To identify the factors associated with Upright Delivery (UD) performed in hospitals linked to the Rede Cegonha (RC) in Brazil.

METHODS

Cross-sectional study with 3,073 parturients who had vaginal delivery in 606 health facilities in Brazil, located in health regions with a regional action plan approved in the RC. Socioeconomic, demographic, and obstetric characteristics of the parturients, organizational and management aspects of maternity hospitals, and work processes in childbirth care were evaluated. The multivariate logistic regression model with a hierarchical approach was adjusted to identify the variables associated with UD (outcome), estimating Odds Ratios (OR) with a significance level of 5%.

RESULTS

Of the evaluated parturient, 6.7% gave birth in the vertical position. The following were associated with a greater chance of PPV: being black (OR=2.07); having 13 or more years of study (OR=3.20); giving birth in a high-risk hospital (OR=1.58); giving birth in PPP rooms (which assisted with labor, delivery, and puerperium in the same environment) in Obstetric Centers (OR=2.07) or in-hospital Normal Delivery Centers (OR=1.62); being assisted by an obstetrician nurse (OR=1.64) or by a midwife (OR=7.62) when compared to a doctor; receiving massage during labor and delivery (OR=1.89); using a stool (OR=4.16) and among women who did not ask for/not receive analgesia (OR=3.15).

CONCLUSION

The UD is an event related to racial aspects and the education of the parturient, being stimulated in health establishments where good practices of childbirth care are implemented, with adequate ambiance, and with multidisciplinary teams comprising midwives and obstetric nurses.

The Role of Midwives in the Course of Natural Childbirth-Analysis of Sociodemographic and Psychosocial Factors-A Cross-Sectional Study

BACKGROUND

An important role in the course of natural childbirth is played by midwives, who should effectively work on relieving pain. This study aims to present the opinions of midwives on non-pharmacological methods of relieving labor pain; the frequency of their use and reasons for their abandonment; and the relationship between the use of non-pharmacological methods of relieving labor pain and perceived job satisfaction, burnout, and self-efficacy of the midwife.

METHODS

The study was conducted online, with the participation of 135 Polish midwives working in the delivery room. The author's survey questionnaire, the Generalized Self-Efficacy Scale (GSES), the LBQ Burnout Questionnaire, and the Scale of Job Satisfaction were used.

RESULTS

Among the surveyed midwives, 77% use vertical positions in work with a patient giving birth. Almost all respondents consider vertical positions as an example of a non-pharmacological method of relieving labor pain; those with master's degree felt more prepared for their use (p = 0.02). The most common reason for abandoning their use was disagreement on the part of co-workers (p = 0.005). An association was observed between the use of vertical positions and the level of burnout (p = 0.001) and a significant correlation between preparation for their use and self-efficacy assessment, burnout, and job satisfaction.

CONCLUSION

Our research shows that it would be important to conduct additional training on the use of non-pharmacological methods to relieve labor pain and to present their benefits. In contrast to other research results, our results showed that midwives feel well prepared to use these methods; however, similar to other research, we found that they often feel disagreement from colleagues and a lack of support from their leaders. The use of vertical positions is related to burnout.

The MIDWIZE conceptual framework: a midwife-led care model that fits the Swedish health care system might after contextualization, fit others

OBJECTIVE

Familiarity with the unique tradition and experience of Swedish midwives during the more than 300 years in which midwife-led care has contributed to one of the lowest maternal and neonatal mortality and morbidity ratio in the world might encourage professionals in other countries to follow the Swedish example. The framework described below, reflecting the midwife's role in the Swedish health care system, might, after implementation, strengthen maternal and neonatal outcomes if contextualized to other settings.

RESULTS

Using a four-step procedure we identified our topic, made a literature review, identified the key components and their internal relationship, and finally developed the MIDWIZE conceptual framework. In this framework, the midwives in collaboration with obstetricians, provide evidence-based care with continuous quality improvements during the whole reproductive life cycle. Teamwork including specialists for referral and a responsive, relational, trust-based practice is the foundation for provision of midwife-led care for healthy women with a normal pregnancy. The well-educated midwife, of high academic standard, promoting gender equality and equity is the hub in the team and the primary care provider.

Examining the impact of upright and recumbent positions on labor outcomes in Saudi Arabia: A quasi-experiment

Background

Helping the woman to adopt a comfortable position during childbirth significantly affects labor changes and pain management. However, there is a lack of consensus on the impacts of different childbirth positions on labor outcomes. In addition, a scarce of studies have assessed the effects of the upright and recumbent positions on delivery outcomes, especially in the Kingdom of Saudi Arabia.

Objective

This study aimed to examine and compare the influence of upright and recumbent childbirth positions on birth outcomes.

Methods

The setting was the childbirth unit at East Jeddah Hospital from November 2020 to March 2021. The research design was quasi-experimental, including 300 women in labor under 18-45 years. The sample includes two equal groups of 150 women: upright (experiment) and recumbent (comparison) position groups. Three tools were used to collect data: a structured interviewing questionnaire, the modified WHO partograph, and the Wong-Baker FACES® pain rating scale. Descriptive statistics, chi-square, independent t-test, and paired t-test were used for data analysis.

Results

Women in the recumbent position spent a longer duration in the first, second, and third stages of childbirth and had higher pain scores and less satisfaction with the assumed position than women in the upright position, with a highly significant difference (p <0.001).

Conclusion

Laboring women in upright positions experienced faster progress of labor, shorter duration of childbirth, less pain, and higher satisfaction than those assumed recumbent positions. This study serves as an input for midwives and nurses to enable them to offer appropriate advice to improve intrapartum care. In addition, educational programs targeting pregnant women about the positive impacts of upright position on women's birth experience are encouraged.

Effect of Flexible Sacrum Position on Maternal and Neonatal Outcomes in Public Health Facilities, Amhara Regional State, Ethiopia: A Quasi-Experimental Study

Restricting women giving birth in health care facilities from choosing the most comfortable position during labor and birth is a global problem. This study was aimed to examine the effect of flexible sacrum birth positions on maternal and neonatal outcomes in public health facilities in Ethiopia's Amhara Region. A non-equivalent control group post-test-only design was employed at public health facilities from August to November 2019. A total of 1048 participants were enrolled and assigned to intervention or control groups based on their choice of birth position. Participants who preferred the flexible sacrum birth position received the intervention, while participants who preferred the supine birth position were placed in the control group. Data were collected using observational follow-up from admission to immediate postpartum period. Log binomial logistic regression considering as treated analysis was used. Of the total participants, 970 women gave birth vaginally, of whom 378 were from the intervention group, and 592 were from the control group. The intervention decreased the chance of perineal tear and poor Apgar score by 43 and 39%, respectively. The flexible sacrum position reduced the duration of the second stage of labor by a mean difference of 26 min. Maternal and newborn outcomes were better in the flexible sacrum position.

Complementary and Integrative Health Practices in a Brazilian Freestanding Birth Center: A Cross-Sectional Study

The study aimed to analyze the use of complementary and integrative health practices (CIHPs) during labor and birth in a freestanding birth center. A total of 28 different CIHPs were applied with or used by laboring women. The most adopted CIHPs were mind-body practices (99.9%) and natural products (35.5%), mostly used by primiparous women (P <.05). Adopting CIHPs can increase care quality, increase positive experiences during childbirth, and promote evidence-based choices.

Culturally appropriate care to support maternal positions during the second stage of labour: Midwives' perspectives in South Africa

Background

‘Doing what the Romans do in Rome’ was an expression raised by one of the midwives following workplace culture and disregarding women’s birth choices. Midwifery practice in South Africa caters for a culturally diverse ethnic groups of childbearing women. Culturally appropriate care highlights the importance of including women in decision-making concerning their birth preferences including maternal positions during labour. Women’s right to choose their maternal position and cultural preferences during labour has been overlooked, leading to poor maternal healthcare provision and negative birth experiences.

Aim

In this article, the researchers aimed to describe and explore midwives’ perspectives on culturally appropriate care to support maternal positions during the second stage of labour.

Setting

Midwives working in the maternity ward in a public hospital in South Africa.

Methods

A qualitative descriptive design using individual interviews was used to collect data. The participants were selected using the purposive sampling method. The study population comprised 20 midwives who volunteered to participate in the study. Data were transcribed manually and analysed using thematic analysis.

Results

The four main themes are as follows: (1) Caring for women from various ethnic groups, (2) midwives disregard women’s beliefs and culture, (3) midwife personal cultural attributes and (4) midwifery unit workplace culture.

Conclusion

The authors concluded that culturally appropriate care towards the women’s choices of birth position during the second stage of labour should form an integral part of the midwifery care rendered.

TheMidwifery Student’s Observations about the Implementation of International Guidelines and Protocols in Greek Maternity Hospitals

Background: Childbirth is a unique experience ina woman’s life and always remains indelibly engraved in her memory. For this reason, it is necessary to ensure appropriate conditions to have a positive birth experience. Thus, guidelines and protocols have been developed by major international organizations that aim to promote normal labor and better care for the mother and fetus without unnecessary interventions. The aim of this study is to investigate whether the international guidelines and protocols are observed in Greek maternity hospitals. Methods: The study involved 124 male and female students from the three departments of Midwifery: University of West Attica, International Hellenic University and University Western Macedonia, which completed an equal number of self-report questionnaires with their socio-demographic data and were then asked to answer questions posed by instructions for normal childbirth. Results: It was observed that many of the guidelines are not followed, such as grooming and enema, prohibition of feeding and fluid intake, application of pressure on the bottom of the uterus, frequent vaginal examination, prohibition in the presence of sessions, continuous cardiotocographic follow-up in low-risk pregnancies, termination of delivery only in a supine gynecological position, routine perineotomy and immediate ligation of the umbilical cord. Conclusions: The purpose of the guidelines is to maintain the natural course of childbirth by avoiding a series of unnecessary acts that alter the naturalness and undermine the rights of women in childbirth.

A biomechanical study of the birth position: a natural struggle between mother and fetus

Birth trauma affects millions of women and infants worldwide. Levator ani muscle avulsions can be responsible for long-term morbidity, associated with 13-36% of women who deliver vaginally. Pelvic floor injuries are enhanced by fetal malposition, namely persistent occipito-posterior (OP) position, estimated to affect 1.8-12.9% of pregnancies. Neonates delivered in persistent OP position are associated with an increased risk for adverse outcomes. The main goal of this work was to evaluate the impact of distinct fetal positions on both mother and fetus. Therefore, a finite element model of the fetal head and maternal structures was used to perform childbirth simulations with the fetus in the occipito-anterior (OA) and OP position of the vertex presentation, considering a flexible-sacrum maternal position. Results demonstrated that the pelvic floor muscles' stretch was similar in both cases. The maximum principal stresses were higher for the OP position, and the coccyx rotation reached maximums of 2.17[Formula: see text] and 0.98[Formula: see text] for the OP and OA positions, respectively. Concerning the fetal head, results showed noteworthy differences in the variation of diameters between the two positions. The molding index is higher for the OA position, with a maximum of 1.87. The main conclusions indicate that an OP position can be more harmful to the pelvic floor and pelvic bones from a biomechanical point of view. On the other side, an OP position can be favorable to the fetus since fewer deformations were verified. This study demonstrates the importance of biomechanical analyses to further understand the mechanics of labor.

Exploring midwives' experiences of implementing the Labour Hopscotch Framework: A midwifery innovation

INTRODUCTION

Midwives are ideally placed to promote physiological birth and improve women's birth experiences. Freedom of movement in labor is highly recommended as it reduces a need for obstetric interventions in labor and prevents and corrects labor complications, such as poor progress and malposition of the fetus. The Labour Hopscotch Framework (LHF) provides women and midwives with a visual depiction of the steps they can undertake to remain active and, in this way, support physiological birth processes. The objective of this study was to explore midwives' experiences of supporting women during labor with the Labour Hopscotch Framework and identify any improvements necessary to the Labour Hopscotch Framework.

METHODS

A two phased mixed-method sequential explanatory design study consisting of a survey (women, n=809 and partners, n=759) and focus group (n=8 midwives) was completed to evaluate the LHF following its implementation. This article presents the findings reporting midwives' perceptions of using the Labour Hopscotch Framework with women and their birthing partners. The setting was a large urban teaching maternity hospital in Dublin, Ireland, where eight midwives practiced in the following areas: labor suite, antenatal unit, and community midwifery.

RESULTS

The Labour Hopscotch Framework was described as beneficial in promoting physiological birth, using a creative, attractive visual depiction to guide women in, and before, labor. The Labour Hopscotch Framework was deemed helpful in increasing midwifery students and newly qualified midwives' confidence to provide women with tangible, supportive assistance during labor and increased partners' involvement in the labor process.

CONCLUSIONS

Labour Hopscotch Framework should be more widely promoted to all women attending the hospital for maternity care and a clear explanation of each step given and demonstrated to increase women's understanding of the steps within. Labour Hopscotch training should be included in midwifery education programs.

Perceptions of women and partners on labor and birth positions: A meta-synthesis

BACKGROUND

The risks and benefits of different birthing positions are commonly studied, but both paternal and maternal preferences and experiences of different birth positions are not examined. Therefore, this systematic review aims to explore the perceptions of women and their partners on birthing positions during the first and second stage of labor, so that maternity health care practitioners can provide better quality patient-centered care.

METHODS

Six databases were searched from each database's inception through November 2020. Qualitative or mixed-methods studies exploring perceptions of women and/or their partners on birthing positions were included in the review. Key information and findings of the studies were extracted; qualitative data were meta-summarized, then meta-synthesized using thematic analysis.

RESULTS

Seven studies were included, and four themes emerged: (a) Influences on choice and preference; (b) mixed experiences from "pain" to "more in control"; (c) impact on postpartum health; and (d) ways to empower couples in their choice.

CONCLUSIONS

Women's preferences for birthing positions were influenced by a myriad of personal and socio-cultural beliefs and traditions. Findings suggest a need for health care practitioners to build better rapport and provide more culturally relevant informational support to both women and their birthing partners, so they are better able to make informed decisions on their preferred birthing position.

Fatores associados à ocorrência de parto em posição vertical no Brasil

RESUMO Objetivo: Identificar os fatores associados aos partos na posição vertical realizados em hospitais vinculados à Rede Cegonha no Brasil. Métodos: Estudo transversal com 3.073 parturientes que tiveram parto vaginal em 606 estabelecimentos de saúde no Brasil, localizados em regiões de saúde com plano de ação regional aprovado na Rede Cegonha. Foram avaliadas características socioeconômicas, demográficas e obstétricas das parturientes, aspectos organizacionais e de gestão das maternidades e processos de trabalho na atenção ao parto. Modelo de regressão logística multivariada com abordagem hierarquizada foi ajustado para identificar as variáveis associadas ao parto na posição vertical (desfecho), estimando-se odds ratio (OR) com nível de significância de 5%. Resultados: Do total de parturientes avaliadas, 6,7% das mulheres tiveram parto na posição vertical. Estiveram associados à maior chance de ocorrência do parto na posição vertical: ser preta (OR=2,07); ter 13 ou mais anos de estudo (OR=3,20); parir em hospital de alto risco (OR=1,58); parir em quartos PPP (que dispunham de assistência ao trabalho de parto, parto e puerpério no mesmo ambiente) em centros obstétricos (OR=2,07) ou em centros de parto normal intra-hospitalares (OR=1,62); ser assistida por enfermeiro obstetra (OR=1,64) ou por obstetriz (OR=7,62) quando comparado ao médico; receber massagem durante o trabalho de parto e parto (OR=1,91); utilizar banqueta (OR=4,35) e entre mulheres que não pediram/não receberem analgesia (OR=3,33). Conclusão: O parto na posição vertical é um evento relacionado a aspectos raciais e à escolaridade da parturiente, sendo estimulado em estabelecimentos de saúde onde estão implantadas boas práticas de assistência ao parto, com ambiência adequada e com equipes multiprofissionais contendo obstetriz e enfermeiro obstetra.

Avaliação da satisfação de mulheres com trabalho de parto e parto em hospital de ensino

RESUMO Objetivo: Avaliar a satisfação de puérperas quanto ao trabalho de parto e parto. Método: Pesquisa analítica e transversal, realizada com puérperas de um hospital de ensino. Os dados foram coletados de outubro a dezembro de 2020, por meio de um questionário sociodemográfico e obstétrico e da Escala de Avaliação da Satisfação com o Parto de Mackey. A escala possui 34 itens divididos em seis domínios, com pontuação mínima de 34 e máxima de 170 pontos. Resultados: Em uma amostra de 243 puérperas, a pontuação média foi de 141 pontos, com desvio padrão de 16,8. Verificou-se alta satisfação das mulheres em todos os domínios da escala e baixa adesão às boas práticas de atenção ao parto e nascimento, recomendadas atualmente. Conclusão: As participantes se mostraram satisfeitas com a experiência. A limitação do processo educativo em saúde durante o pré-natal pode diminuir o discernimento e o julgamento crítico das parturientes.

Assessment of women’s satisfaction with labor and childbirth at a teaching hospital

ABSTRACT Objective: To assess the satisfaction of puerperal women regarding labor and childbirth. Method: Analytical and cross-sectional research carried out with puerperal women at a teaching hospital. Data were collected from October to December 2020 by a sociodemographic and obstetric questionnaire and the Mackey Childbirth Satisfaction Rating Scale. The scale has 34 items divided into six domains, with a minimum score of 34 and a maximum of 170 points. Results: The mean score was 141 points in a sample of 243 puerperal women, with a standard deviation of 16.8. There was high satisfaction among women in all domains of the scale and low adherence to the best practices in labor and childbirth care currently recommended. Conclusion: The women were satisfied upon the experience. The limitation of the health education process during prenatal care may reduce the parturient’ discernment and critical judgment.

Challenges to implement evidence-based midwifery care in Bangladesh. An interview study with medical doctors mentoring health care providers

BACKGROUND

In 2013 the first midwives in Bangladesh to be educated according to international standards completed their course and were awarded a diploma. Sixty percent of their training took place in clinical placement sites. In order to achieve appropriate mentor support while in clinical practice, a mentorship programme was initiated whereby local doctors were appointed by Save the Children. The aim of this study is to describe the mentors' purpose and the actions they took to improve midwifery care at clinical placement sites. Their appointment was intended to support local Health Care Providers (HCPs) at clinical placement sites meant for educating midwifery students in evidence-based midwifery care.

METHODS

An open-ended interview study with 14 mentors. The data was analysed using content analysis.

RESULTS

The main category, the theme that emerged from the analysis was "Creating commitment". "Creating commitment" describe how the mentors; the medical doctors employed by Save the Children, "Motivate", "Educate", "Mentor", "Advocate" and "Communicate" (subcategories) to creating commitment for quality midwifery care "In the organization of care" and "In clinical care practices" (categories). As intended, they enabled HCPs, midwifery students, and newly graduated midwives to provide quality midwifery care.

CONCLUSIONS

Using medical doctors' status and power to support the development of a newly emerging midwifery cadre in a country where midwifery is just emerging as a profession is because midwives integrated in the health system will improve the birthing process, improve life chances for newborns, and reduce morbidity and mortality in Bangladesh. It is recommended for implementation in other similar national contexts.

Implementing an internet-based capacity building program for interdisciplinary midwifery-lead teams in Ethiopia, Kenya Malawi and Somalia

The Swedish care model MIDWIZE defined as midwife-led interdisciplinary care and zero separation between mother and newborn, was implemented in 2020-21 in Ethiopia, Kenya, Malawi, and Somalia in a capacity building programme funded by the Swedish Institute.

OBJECTIVE

To determine the feasibility of using an internet-based capacity building programme contributing to effective midwifery practices in the labour rooms through implementation of dynamic birthing positions, delayed umbilical cord clamping and skin-to-skin care of newborns in the immediate postnatal period.

METHODS

The design is inspired by process evaluation. Focus group discussions with policy leaders, academicians, and clinicians who participated in the capacity building programme were carried out. Before and after the intervention, the numbers for dynamic birthing positions, delayed umbilical cord clamping and skin-to-skin care of the newborn in the immediate postnatal period were detected.

RESULTS

Participants believed the internet-based programme was appropriate for their countries' contexts based on their need for improved leadership and collaboration, the need for strengthened human resources, and the vast need for improved outcomes of maternal and newborn health.

CONCLUSION

The findings provide insight into the feasibility to expand similar online capacity building programmes in collaboration with onsite policy leaders, academicians, and clinicians in sub-Saharan African countries with an agenda for improvements in maternal and child health.

Standing up for your birth rights: An intersectional comparison of obstetric violence and birth positions between Quichua and Egyptian women

Obstetric violence is a pervasive phenomenon in reproductive health across the world. Denial of the choice in birth position is a common form of obstetric violence as horizontal positions are non-evidence based, yet routinely imposed. This contributes to the cultural barriers to access reproductive health care. The present study compares women's experiences in childbirth from the Quichua and Egyptian communities, exploring the intersectional factors that contribute to obstetric violence and the adoption of preferred birth positions to offer recommendations on implementing respectful and rights-based reproductive care. Two independent scoping reviews have been carried out and subsequently compared. The intersectional approach revealed how gender, race, and class have a multiplicative effect on the denial of choice in birth position as a form of obstetric violence. This phenomenon exacerbates the pre-existing health disparities that disproportionately affect women, indigenous and racialized groups, and people living in poverty. Culturally competent, multilevel, and multidisciplinary interventions, strengthening of health systems, and community participation are essential to combat discrimination and guarantee birth rights. Allowing women to choose their birth position is a low-hanging fruit to challenge the complex issue of obstetric violence and ensure a rights-based approach to reproductive health.

"I knew there has to be a better way": Women's pathways to freebirth in Poland

BACKGROUND

Each year a small number of women decide to birth at home without midwifery and medical assistance despite the availability of maternity services in the country. This phenomenon is called freebirth and can be used as a lens to look into shortcomings of maternity care services.

AIM

By exploring women's pathways to freebirth, this article aims to examine the larger context of maternity services in Poland and identify elements of care contributing to women's decision to birth without midwifery and medical assistance.

METHODS

A qualitative methodology was used employing elements of ethnographic fieldwork, including digital ethnography. Semi-structured interviews with twelve women who freebirth, analysis of online support groups, secondary sources of information and elements of participant observation were used.

FINDINGS

Women's decisions to freebirth were born out of their previous negative experiences with maternity care. Persistent use of medical technology and lack of respect from maternity care providers played a major role in pushing women away from available Polish maternity services. While searching for a better environment for themselves and their babies for the subsequent births, women experienced a rigidity of both mainstream and homebirth services and patchy availability of the latter that contributed to their decisions to freebirth.

CONCLUSIONS

Freebirth appears to be a consequence of inadequate maternity services both mainstream and homebirth rather than a preference. Women's freebirth experiences can be used to improve maternity care in Poland and inform similar contexts globally.

Obstetric iatrogenesis in the United States: the spectrum of unintentional harm, disrespect, violence, and abuse

'Medical iatrogenesis' was first defined by Illich as injuries 'done to patients by ineffective, unsafe, and erroneous treatments'. Following Lokumage's original usage of the term, this paper explores 'obstetric iatrogenesis' along a spectrum ranging from unintentional harm (UH) to overt disrespect, violence, and abuse (DVA), employing the acronym 'UHDVA' for this spectrum. This paper draws attention to the systemic maltreatment rooted in the technocratic model of birth, which includes UH normalized forms of mistreatment that childbearers and providers may not recognize as abusive. Equally, this paper assesses how obstetric iatrogenesis disproportionately impacts Black, Indigenous, and People of Color (BIPOC), contributing to worse perinatal outcomes for BIPOC childbearers. Much of the work on 'obstetric violence' that documents the most detrimental end of the UHDVA spectrum has focused on low-to-middle income countries in Latin America and the Caribbean. Based on a dataset of 62 interviews and on our personal observations, this paper shows that significant UHDVA also occurs in the high-income U.S., provide concrete examples, and suggest humanistic solutions.

Exploring the perspective of nursing staff or caregivers on birthing positions in Central India

Introduction

Maternal birthing positions refer to the various physical postures a pregnant mother may assume at the time of delivery. The World Health Organisation recommends that woman should be given an opportunity to make a choice on the type of position to use during labour. Alternative birth positions are associated with lower incidence rates of performing episiotomy, less perineal tears and less use of instrumental deliveries. Nurses' perspective on women's positions has rarely been explored in India. Present study aims at assessing the knowledge regarding alternative birth positions among nursing officers.

Materials and Methods

This cross-sectional observational study was conducted on 52 nursing officers who were posted in the labour room. A pretested questionnaire was administered to them. Data analysis was done using SPSS software version 22.

Results

Majority (82.7%) of nursing officers felt that there is a need of giving a choice to the woman regarding alternate birth position. 76.9% of them were aware of position other than lithotomy. Around 48.1% would recommend squatting position to a woman in labour. Ease and convenience in conducting the delivery was the foremost reason chosen in advocating a birth position. Whereas overcrowding in the labour room, ignorance about alternate positions and difficulty in converting to instrumental delivery were cited as reasons of not recommending these positions.

Conclusion

Educating nursing officers about emerging evidence regarding birthing positions will enable them to give accurate information to women.

Effect of the birthing position on its evolution from a biomechanical point of view

BACKGROUND AND OBJECTIVE

During vaginal delivery, several positions can be adopted by the mother to be more comfortable and to help the labor process. The positions chosen are very influenced by factors such as monitoring and intervention during the second stage of labor. However, there is limited evidence to support the most ideal birthing position. This work aims at contributing to a better knowledge associated with the widening of the pubic symphysis and the biomechanics of flexible and non-flexible sacrum positions that can be adopted during the second stage of labor, as well as their resulting pathophysiological consequences.

METHODS

A validated computational model composed by the pelvic floor muscles attached to the bones, and a fetus head was used to simulate vaginal deliveries. This model was modified to mimic two birthing positions: one that allows the free movement of the coccyx as in flexible sacrum positions and other in which this movement is more restricted as in non-flexible sacrum positions. The widening of the pubic symphysis was also considered to facilitate the passage of the fetus head.

RESULTS

The results obtained showed that, in non-flexible sacrum positions, where the coccyx movement is restricted, occur a rotation of 3.6° of the coccyx and a widening of 6 mm of the pubic symphysis. In contrast, in flexible sacrum positions, where the coccyx is free to move, occur a rotation of 15.7° of the coccyx and a widening of the pubic symphysis of 3 mm, appearing to be more beneficial for the mother's pelvis, but slightly higher stresses were detected in the pelvic floor muscles.

CONCLUSIONS

Globally, the results obtained allow to conclude that different birthing positions lead to changes in the female pelvic space, so certain positions can be adopted by the mother during the second stage of labor to reduce the risk of obstructed labor and the development of several dysfunctions. More specifically, flexible sacrum positions, such as kneeling, standing, squatting and sitting positions, are more beneficial for the bone structure of her pelvis as they allow a higher coccyx movement and lower widening of the pubic symphysis.

Birth and the Big Bad Wolf: Biocultural Evolution and Human Childbirth, Part 2

In Part 2 of this two-part article, we further employ the lens of evolutionary medicine to explore similarities in premodern biocultural features of birth, arguing that these were an outgrowth of our common evolutionary heritage as bipedal primates. These practices grew out of the empiricism of millennia of trial and error and supported humans to give birth in closer alignment with our evolved biology. We argue that many common obstetric procedures today work against this evolved biology. In seeking to manage birth, we sometimes generate an obstetric paradox wherein we (over)intervene in human childbirth to try to keep it safe, yet thereby cause harm. We describe premodern birthing patterns in three sections: (a) eating and drinking at will and unrestrained movement in labor with upright pushing; (b) obligate midwifery and continuous labor support; and (c) the low-intervention birth/long-term breastfeeding/co-sleeping adaptive complex, and discuss how these are still relevant today. We conclude with a set of suggestions for improving the global technocratic treatment of birth and with a futuristic epilogue about a 7th, cyborgian pig that asks: What will become of birth as humans continue to coevolve with our technologies?
