Determination of remifentanil in neonatal dried blood spots by liquid chromatography-tandem mass spectrometry

Remifentanil is an ultra-short-acting synthetic opioid-class analgesic which might be increasingly used "off-label" as pain management during labour. Side effects in parturients during labour, and in the infant at birth are of particular concern, especially respiratory depression which is concentration-dependent, and can occur at levels as low as 3-5 ng mL-1. The safety of such use, particularly in newborns due to remifentanil placental transfer, has not been fully demonstrated yet, partly due to the lack of a suitable non-invasive analytical method. The aim of our work was to develop a sensitive method to monitor the levels of remifentanil in neonates by a non-invasive sampling of umbi lical cord blood to support efficacy and safety trials. The presented LC-MS method is sensitive enough to reliably quantify remifentanil in just 20 µL of blood at only 0.3 ng mL-1. The dried blood spot sample preparation included solvent extraction with subsequent solid-phase extraction. The method was validated in terms of accuracy, precision, recovery, matrix effect, and stability, and was successfully applied to a small pilot study. The estimated arterial blood concentrations at the time of delivery ranged from 0.2 to 0.3, and up to 0.9 ng mL-1 in neonatal, and maternal samples, respectively.

Second twin outcome at birth: retrospective analysis in a single tertiary centre in Malaysia

OBJECTIVES

To investigate factors associated with outcome of second twin during labour.

METHODS

The study was a retrospective cohort study in a single tertiary centre in Malaysia from 2014 until 2018 involving all twin pregnancies delivered at or more than 24 weeks of gestation.

RESULTS

Total of 409 twin pregnancies were included. Dichorionic twin comprises of 54.5 % (n=223) and 45.5 % (n=186) are monochorionic. Women with dichorionic pregnancies are significantly older (p<0.001), have more pre-existing medical disorders (p=0.011) and fetal structural anomalies (p=0.009). Monochorionic pregnancies are significantly more amongst Malay (p=0.01) and conceived spontaneously (p<0.001). There are significantly more fetuses both in cephalic presentation (p=0.026), birthweight discrepancy more than 20 % (p=0.038) and shorter mean inter-twin delivery duration (p=0.048) in monochorionic pregnancies. Second twin delivered with Apgar score <7 is significantly more in dichorionic pregnancies (p=0.006). The second twin is associated with lower birthweight, small for gestational age and arterial cord pH<7.25. Within the group of women who delivered both fetuses vaginally, there was significantly more second twins with intertwin delivery duration less than 30 min who were delivered vaginally without instrumentation (p=0.018). There was significantly more second twin with intertwin delivery duration of 30 min and more with arterial cord pH<7.25 (p=0.045). Those who delivered spontaneously had inter-twin delivery duration within 15-29 min. The outcome of second twin is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth.

CONCLUSIONS

The neonatal outcome for the second twin at birth is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth in a cohort managed with non-active management of the second twin in Malaysia.

A double-blinded randomised controlled study of fluid restriction versus liberal fluid during induction of labour: A pilot study

BACKGROUND

Excess intravenous fluid for women requiring an induction of labour may adversely affect the duration of labour and maternal/neonatal outcomes.

AIMS

This study aimed to determine the difference in duration of labour and outcomes with a low background infusion rate, compared to liberal background intravenous fluid management.

MATERIALS AND METHODS

A double blind randomised controlled pilot study was performed on 200 women who underwent induction of labour at a single institution. Women were randomised to an intravenous rate of 40 mL/h versus 250 mL/h of Hartmann's solution. Fluid boluses were strictly controlled to limit bias. This trial was registered with the Australian clinical trial registry: ACTRN12621001298808.

RESULTS

Analysis of the total amount of fluid received showed good separation with Group 1 (40 mL/h) receiving 1,736 mL less than Group 2 (250 mL/h), median (interquartile range) 841 mL (458, 1691) versus 2,577 mL (1620, 4326) (P < 0.001). Median duration of labour was shorter in Group 1 by 24 min (P = ns). Subset analysis of nulliparous women showed that duration of labour was shorter in Group 1 by 83.5 min (P = ns).

CONCLUSION

As this was a pilot study, a significant difference in duration of labour or secondary outcomes was not seen. Given the increasing numbers of nulliparous women having an induction of labour, potential for adverse maternal and neonatal outcomes and the associated higher rate of operative birth, this study guides power calculations and supports proof of concept for future research into optimum fluid management during induction of labour for these women.

Obstetrician views on Fetal Pillow® device use and research in Aotearoa New Zealand: A cross-sectional survey

BACKGROUND

There is anecdotal evidence of Fetal Pillow® use, but no formal local information on clinician practices and perspectives.

AIMS

To assess obstetrician use of the Fetal Pillow®, knowledge of relevant research, and interest in a proposed randomised controlled trial in Aotearoa New Zealand.

MATERIALS AND METHODS

Anonymous cross-sectional survey of practising obstetricians and obstetric trainees in Aotearoa New Zealand distributed by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

RESULTS

Of 136 respondents (69% specialists and 31% trainees), 130 had heard of the Fetal Pillow® device, and 108 had used it at least once (43% more than ten times). The device was available in 17/21 units represented. The 108 users of the device reported this was most commonly on collegial advice (63%) or after personal experience of a difficult delivery (33%) and most (80%) believed it reduced maternal morbidity. Only around one-third of the 130 respondents who had heard of the device agreed there was adequate research demonstrating its efficacy for maternal (36%) and neonatal (30%) morbidity. The majority reported they would change practice in response to a randomised trial, although they were more likely to start use (81% of current non-users) than stop (53% of users). Most (70%) respondents agreed they would encourage patients to participate in a randomised trial.

CONCLUSIONS

The Fetal Pillow® is available in most maternity units in Aotearoa New Zealand. The majority of obstetric clinicians believe it reduces maternal morbidity, while acknowledging the lack of scientific evidence. Most would support a randomised trial.

Determinants of obstructed labour and associated outcomes in 54 referral hospitals in Nigeria

OBJECTIVE

To estimate the prevalence of obstructed labour, associated risk factors and outcomes across a network of referral hospitals in Nigeria.

DESIGN

Retrospective observational study.

SETTING

A total of 54 referral-level hospitals across the six geopolitical regions of Nigeria.

POPULATION

Pregnant women who were diagnosed with obstructed labour during childbirth and subsequently underwent an emergency caesarean section between 1 September 2019 and 31 August 2020.

METHODS

Secondary analysis of routine maternity care data sets. Random-effects multivariable logistic regression was used to ascertain the factors associated with obstructed labour.

MAIN OUTCOME MEASURES

Risk factors for obstructed labour and related postpartum complications, including intrapartum stillbirth, maternal death, uterine rupture, postpartum haemorrhage and sepsis.

RESULTS

Obstructed labour was diagnosed in 1186 (1.7%) women. Among these women, 31 (2.6%) cases resulted in maternal death and 199 (16.8%) cases resulted in postpartum complications. Women under 20 years of age (OR 2.03, 95% CI 1.50-2.75), who lacked formal education (OR 1.88, 95% CI 1.55-2.30), were unemployed (OR 1.94, 95% CI 1.57-2.41), were nulliparous (OR 2.11, 95% CI 1.83-2.43), did not receive antenatal care (OR 3.34, 95% CI 2.53-4.41) or received antenatal care in an informal healthcare setting (OR 8.18, 95% CI 4.41-15.14) were more likely to experience obstructed labour. Ineffective referral systems were identified as a major contributor to maternal death.

CONCLUSIONS

Modifiable factors contributing to the prevalence of obstructed labour and associated adverse outcomes in Nigeria can be addressed through targeted policies and clinical interventions.

Translation and validation of Vietnamese version of the Birth Satisfaction Scale-Revised (BSS-R)

BACKGROUND

The 10-item Birth Satisfaction Scale-Revised (BSS-R) is a quick and easy survey instrument recommended by the International Consortium for Health Outcome Measures as the tool of choice for measuring women's birth satisfaction.

AIM

To translate and validate a Vietnamese-language version of the BSS-R.

METHOD

A quantitative cross-sectional method was used to gather data post translation and back-translation of a Vietnamese version of the BSS-R (VN-BSS-R). Data collected were psychometrically evaluated using key indices of validity and reliability.

PARTICIPANTS

Vietnamese women who were within one month postpartum of birth (N = 383) took part in the study.

RESULTS

Findings illustrate that a two-factor model offered excellent psychometric properties. With the two-factor VN-BSS-R, five items loaded onto a subscale 'Positive birth experiences' and the other five onto a second subscale 'Negative birth experiences'. This two-factor model offered a fit to data (root mean square error of approximation [RMSEA] = 0.07, 90% confidence interval [CI] [0.05, 0.09], root square mean residual [RMSE] = 0.04 and comparative fit index [CFI] = 0.97). Mean scores for the exploratory factor analysis [EFA]-derived 'positive' and 'negative' sub-scales were 17.12 (SD 2.34) and 8.40 (SD 4.18) respectively.

CONCLUSION

The translated and validated VN-BSS-R is a psychometrically robust tool for measuring birth satisfaction in Vietnamese postpartum women.The VN-BSS-R is available for use to measure experiences and perceptions of intrapartum care received by Vietnamese women.

Parents' descriptions of labouring with an antepartum fetal death: Findings from the Birthing in Grief study

BACKGROUND

Evidence to guide intrapartum care when an unborn baby has died is limited.

AIMS

To explore parents' experiences of care during labour of an antepartum stillbirth.

MATERIALS AND METHODS

Semi-structured interviews with 18 bereaved parents from across Australia. Content analysis was conducted.

FINDINGS

Two broad themes were identified: 'explaining every step' and 'helping us feel like parents.' Sub-themes under the first broad theme, 'explaining every step', were 'how and when information was given' and 'what happens next.' 'Like any other parent', 'feeling the pain' and 'everything is clouded' were sub-themes of the second broad theme. These findings mapped to current Australian clinical practice guidelines for bereavement care around stillbirth and neonatal death, ie good communication, recognition of parenthood, shared decision making and effective support.

CONCLUSIONS

This study on parents' experiences of labour with a fetal death in utero brings an important perspective to intrapartum care for this group. As far as we are aware, this study is the first to focus solely on this aspect of care. Our findings could be readily mapped to the four perinatal bereavement care goals. Parents wanted care providers to facilitate their choices, their sense of control, their autonomy and their agency. They wanted to feel that they had received the 'best' care available.

Parturients feel capable of giving informed consent for epidural analgesia: A qualitative and quantitative analysis

INTRODUCTION

The patient's right to autonomy confirmed by informed consent is a cornerstone in modern medicine. Epidural analgesia is increasingly popular in obstetric analgesia, but physicians disagree whether labour pain impairs parturient decision-making. We investigated the fraction of parturients feeling capable of giving informed consent including their knowledge of risks.

METHODS

Bedside survey postpartum women at the Herlev Hospital, Denmark. The inclusion criteria were recipient of epidural analgesia during labour. A power calculation based on the recognition of genuine and false side effects required the inclusion of 50 participants.

RESULTS

Forty out of fifty (80%) of the participants felt they could make a judicious consent during labour and 46 out of 50 (92%) felt they knew enough about epidural analgesia to give consent to the procedure again if necessary. Participants spontaneously reported a median of two risks associated with epidural analgesia. Additionally, when prompted with a cued list of true and false risks from epidural analgesia, the participants reported on average 5.1 genuine risks compared with 0.4 made-up risks. The difference (4.7) suggests the included women could discern genuine risks from made-up risks.

DISCUSSION

The majority of participants reported the capacity to give informed consent. Our quantitative results show the participants could clearly distinguish genuine risks of epidural labour analgesia from made-up risks. Our qualitative data likewise suggest that participants understood the information and consequently their informed consent was genuine. Accordingly, parturients are able to give informed consent. This is supported by parturients' ability to identify risks from epidural labour analgesia.

Development of a novel labour monitoring tool: Improving labour care quality in the Indian setting

Introduction

Efficient care by labour monitoring tools manages labour, identifies the abnormalities and avoids the fatalities. Various studies are being undertaken by the researchers to understand the limited use of these therapeutic tools. The present study aimed to develop a novel labour monitoring instrument after understanding the barriers and enablers of the currently used tools and using it in the health setting for improving clinical outcomes.

Materials and Methods

Methodological research design was adopted to develop the novel tool. Item pool was generated by literature review, focus group discussions and retrospective observations of the partographs. Developed tool was evaluated by various experts by undergoing three rounds and was found to be reliable in terms of stability and equivalency. After undergoing pilot runs by researcher and nurses, tool was found to be feasible and understandable. The developed novel labour monitoring tool was used on 200 intranatal women.

Results

Focus group discussions revealed various barriers in the current labour tools, such as lack of clarity, complexity, staff shortage, workload etc. Retrospective observation of filled partographs revealed the incomplete recording of the components of the partograph. The prepared first draft underwent rigorous review by the experts. The prepared novel tool, after being used on 200 intranatal women resulted in 90% of normal vaginal deliveries. Duration of 1st stage of labour was around 5 hours.

Conclusion

A novel labour monitoring tool was developed after methodological approach resulting in adequate monitoring and improved labour outcomes.

Dark citizen science

Citizen science is often celebrated. We interrogate this position through exploration of socio-technoscientific phenomena that mirror citizen science yet are disaligned with its ideals. We term this 'Dark Citizen Science'. We identify five conceptual dimensions of citizen science - purpose, process, perceptibility, power and public effect. Dark citizen science mirrors traditional citizen science in purpose and process but diverges in perceptibility, power and public effect. We compare two Internet-based categorisation processes, Citizen Science project Galaxy Zoo and Dark Citizen Science project Google's reCAPTCHA. We highlight that the reader has, likely unknowingly, provided unpaid technoscientific labour to Google. We apply insights from our analysis of dark citizen science to traditional citizen science. Linking citizen science as practice and normative democratic ideal ignores how some science-citizen configurations actively pit practice against ideal. Further, failure to fully consider the implications of citizen science for science and society allows exploitative elements of citizen science to evade the sociological gaze.

The use of hydrotherapy in the first stage of labour: A systematic review and meta-analysis

AIM

To explore the effect of hydrotherapy applied in the first stage of labour on the health of mother and newborn.

METHODS

This systematic review and meta-analysis was carried out by following PRISMA. The studies were obtained by scanning EBSCO, PubMed, Science Direct, Ovid, Web of Science and Scopus electronic databases. Twenty studies published between 2013 and 2023 were included.

RESULTS

The total sample size of the studies was 8254 (hydrotherapy: 2953, control: 5301). Meta-analyses showed that the perception of pain decreased, comfort level and vaginal birth rate were higher and assisted vaginal birth rate and APGAR scores in the first minute were lower in women who underwent hydrotherapy. There was no difference between groups in terms of the duration of the first and second stage of labour, episiotomy, perineal trauma, intrapartum and postpartum bleeding amounts, use of pain medication and labour augmentations, APGAR scores in the fifth minute, positive neonatal bacterial culture and neonatal intensive care unit need.

CONCLUSION

This study revealed that the results that hydrotherapy decreased the perception of pain and assisted birth, increased the rate of vaginal birth and comfort level and did not adversely affect the health of the mother and baby during the birth process.

Maternal intrapartum fever during epidural labour analgesia: Incidence and influencing factors

BACKGROUND

The management and nursing care of women's temperature during delivery is an important part of clinical obstetrics. We aimed to evaluate maternal intrapartum fever during epidural labour analgesia to provide evidence for the management and care of women in labour.

METHODS

This study was conducted and reported according to the STROBE statement. Women in labour undergoing epidural labour analgesia in our hospital from 1 January 2021 to 31 August 2022 were retrospectively selected. The characteristics of women in labour with and without intrapartum fever were compared. Pearson correlation and logistic regression analysis were used to analyse the influencing factors of postpartum fever.

RESULTS

A total of 196 women in labour were included, the incidence of maternal intrapartum fever in women in labour undergoing epidural analgesia was 27.5%. Pearson correlation analyses showed that BMI, oxytocin use, labour duration, number of vaginal examinations, time from rupture of the foetal membranes to the end of labour and duration of epidural analgesia were all correlated with the occurrence of intrapartum fever (all P < 0.05). Logistic regression analyses indicated that body mass index ≥28 kg/m2 (OR = 1.825), oxytocin use (OR = 2.082), labour duration ≥9.2 h (OR = 2.613), number of vaginal examinations ≥8 (OR = 2.044-3.115), the time from rupture of the foetal membranes to the end of labour ≥250 min (OR = 2.766) and duration of epidural analgesia ≥300 min (OR = 3.106) were risk factors for intrapartum fever in women in labour undergoing epidural analgesia (all P < 0.05).

CONCLUSIONS

Maternal intrapartum fever in women in labour undergoing epidural analgesia is common and influenced by many factors. Nurses should take early preventive care measures according to these factors during epidural analgesia in labour.

Utilisation of partogram at a district in the North West Province, South Africa

Background

The partogram or partograph is a tool used to monitor the progress of labour and serves as a diagnostic tool for labour-related abnormalities such as prolonged labour, cephalopelvic disproportion (CPD) and obstructed labour. Appropriate utilisation of the partogram aids health caregivers with early diagnosis and facilitates clinical judgement and interventions to prevent complications of abnormal labour. The partogram is thus a mandatory tool to be utilised to monitor the progress of labour for intrapartum care in South Africa.

Aim

This study aimed to assess and describe the utilisation of the partogram in a district of the North West Province.

Setting

The study was conducted in the private rooms of facilities rendering maternity services in the district.

Methods

A quantitative cross-sectional descriptive design was employed. A purposive sampling was used to select healthcare facilities, and simple random sampling was employed to select plotted partograms. Data were collected using a checklist and analysed using Statistical Package for Social Sciences software version 22.

Results

A total of 279 partograms were analysed. The average partogram utilisation was 20% correct and 80% substandard or not recorded. All files had partogram documents included.

Conclusion

A large percentage (80%) of the partograms were not completed according to the World Health Organization (WHO) standards. There was a concern about high proportions of unrecorded parameters such as monitoring of foetal and maternal conditions, and the progress of labour.

Contribution

The findings and recommendations of the study could improve partogram utilisation in maternity care.

PGF2α induces a pro-labour phenotypical switch in human myometrial cells that can be inhibited with PGF2α receptor antagonists

Preterm birth is the leading cause of infant morbidity and mortality. There has been an interest in developing prostaglandin F2α (PGF2α) antagonists as a new treatment for preterm birth, although much of the rationale for their use is based on studies in rodents where PGF2α initiates labour by regressing the corpus luteum and reducing systemic progesterone concentrations. How PGF2α antagonism would act in humans who do not have a fall in systemic progesterone remains unclear. One possibility, in addition to an acute stimulation of contractions, is a direct alteration of the myometrial smooth muscle cell state towards a pro-labour phenotype. In this study, we developed an immortalised myometrial cell line, MYLA, derived from myometrial tissue obtained from a pregnant, non-labouring patient, as well as a novel class of PGF2α receptor (FP) antagonist. We verified the functionality of the cell line by stimulation with PGF2α, resulting in Gαq-specific coupling and Ca2+ release, which were inhibited by FP antagonism. Compared to four published FP receptor antagonists, the novel FP antagonist N582707 was the most potent compound [Fmax 7.67 ± 0.63 (IC50 21.26 nM), AUC 7.30 ± 0.32 (IC50 50.43 nM), and frequency of Ca2+ oscillations 7.66 ± 0.41 (IC50 22.15 nM)]. RNA-sequencing of the MYLA cell line at 1, 3, 6, 12, 24, and 48 h post PGF2α treatment revealed a transforming phenotype from a fibroblastic to smooth muscle mRNA profile. PGF2α treatment increased the expression of MYLK, CALD1, and CNN1 as well as the pro-labour genes OXTR, IL6, and IL11, which were inhibited by FP antagonism. Concomitant with the inhibition of a smooth muscle, pro-labour transition, FP antagonism increased the expression of the fibroblast marker genes DCN, FBLN1, and PDGFRA. Our findings suggest that in addition to the well-described acute contractile effect, PGF2α transforms myometrial smooth muscle cells from a myofibroblast to a smooth muscle, pro-labour-like state and that the novel compound N582707 has the potential for prophylactic use in preterm labour management beyond its use as an acute tocolytic drug.

The psychosomatic experiences of women who had intrauterine foetal death in rural South Africa

BACKGROUND

 Intrauterine foetal death (IUFD) is a traumatic event leading to substantial grief reactions with a variety of experiences in an expectant woman. After delivery, these experiences have shown to impact the mother's psychological well-being, where she experiences post-traumatic stress, sadness, anxiety and depression. The psychosomatic experiences before labour commenced are not known.

OBJECTIVES

 This study explored the psychosomatic (mind-body connection) experiences of women who had an IUFD before labour commenced in rural areas of Limpopo province, South Africa.

METHOD

 A qualitative approach with an explorative descriptive design was carried out among all 10 consented participants who were selected using a purposive sampling technique. The sample consisted of women who delivered an IUFD as reflected by the hospital register from the selected hospitals. Data were collected at the participants' homes through in-depth individual interviews guided by one open-ended central question as follows, 'Please share with me your experiences of IUFD before you went into labour', and analysed using Tesch's open coding method.

RESULTS

 Two themes reflecting the psychosomatic (mind-body connection) experiences of women who had an IUFD emerged from the analysis. The themes are danger alerts and emotional responses.

CONCLUSION

 This qualitative study revealed that women could relate a lack of or decreased foetal movement as the danger alert or warning sign that the baby was in danger before labour commenced. Upon noticing that something was wrong with the baby, a message was sent to the women's minds, which equally affected and activated their emotional dimensions. An investigation regarding the kind of support needed by women after being informed of an IUFD is recommended.

The association between labour epidural analgesia and postpartum depression in primiparous patients: a historical cohort study

PURPOSE

Peripartum pain has been associated with postpartum depression (PPD), and labour epidural analgesia (LEA) may be able to modify this risk. The objective of this historical cohort study was to examine the association between LEA and PPD among primiparous patients.

METHODS

With institutional research ethics board approval, a provincial perinatal database was searched for primiparous patients who delivered a liveborn singleton infant between 2004 and 2018. Those patients who experienced PPD following their first delivery were identified by a history of PPD in the perinatal records of their second pregnancy. We used logistic regression to compute odds ratios (ORs) for the association between LEA and PPD and performed an adjusted analysis to control for confounding variables.

RESULTS

A total of 35,437 primiparous patients were identified, 67% (n = 23,599) of whom received LEA. In the cohort, 3.7% (n = 1,296) of patients developed PPD. Patients who received LEA had increased odds of developing PPD compared with patients who did not receive LEA (adjusted OR, 1.29; 95% confidence interval [CI], 1.12 to 1.48). In a multivariable regression model, LEA remained a significant predictor for PPD, as did body mass index, pre-existing anxiety, and maternal antidepressant use.

CONCLUSION

This historical cohort study found an association between LEA and PPD among primiparous patients who subsequently had a second pregnancy in the same province. The findings call into question the hypothesis that LEA decreases the risk for PPD and further illustrates the complexities of PPD.

Barriers and enablers to implementing an induction of labour guideline: A clinician survey

BACKGROUND

Clinical guidelines improve outcomes, but poor compliance with recommendations is common. Insight into perceived barriers and enablers to the implementation of guidelines can engage maternity care providers and inform strategies for effective implementation.

AIM

To identify the perceived barriers and enablers to implementing the 2020 'Induction of Labour [IOL] in Aotearoa New Zealand; a Clinical Practice Guideline.'

MATERIALS AND METHODS

Electronic anonymous survey of clinical leaders in midwifery, obstetrics, and neonatology in New Zealand, from August to November 2021. Recruitment of participants was initially through provided lists of national clinical leads, followed by chain sampling.

RESULTS

There were 32 of 89 surveys returned (36%). The most frequently identified enablers were implementation tools such as 'standardised IOL request form' and 'peer review process,' and administrative support and dedicated time. Six maternity hospitals already had peer review in place, whereby IOL requests that did not adhere to guidelines were reviewed by a multidisciplinary group of senior colleagues or peers, with individual feedback to the referring clinician. Attitudes in the form of 'existing systems, routines and culture' was the most frequently identified barrier, followed by external barriers such as 'lack of human resources.'

CONCLUSIONS

Overall, few barriers were identified to implementing this guideline, and some of the key enablers were already in place. The identified enablers warrant future research to develop and evaluate effectiveness in improving outcomes.

The Effects of Music-Based Interventions for Pain and Anxiety Management during Vaginal Labour and Caesarean Delivery: A Systematic Review and Narrative Synthesis of Randomised Controlled Trials

Music-based interventions are not physically invasive, they usually have minimal side effects, and they are increasingly being implemented during the birthing process for pain and anxiety relief. The aim of this systematic review is to summarise and evaluate published, randomised controlled trials (RCTs) assessing the effects of music-based interventions for pain and anxiety management during vaginal labour and caesarean delivery. Following the PRISMA guidelines, a systematic search of the literature was conducted using: PsychInfo (Ovid), PubMed, and Web of Science. Studies were included in the review if they were RCTs that assessed the effects of music on pain and anxiety during vaginal and caesarean delivery by human mothers. A narrative synthesis was conducted on 28 identified studies with a total of 2835 participants. Most, but not all, of the included studies assessing music-based interventions resulted in reduced anxiety and pain during vaginal and caesarean delivery. Music as part of a comprehensive treatment strategy, participant-selected music, music coupled with another therapy, and relaxing/instrumental music was specifically useful for reducing light to moderate pain and anxiety. Music-based interventions show promising effects in mitigating pain and anxiety in women during labour. However, the long-term effects of these interventions are unclear.

Unveiling contextual influences of maternal satisfaction with labour care services in Nigeria: A qualitative inquiry

BACKGROUND

In light of the rising global effort to lower maternal mortality rates, it is crucial for low- and middle-income countries with poor maternal indices to investigate the problem of maternal satisfaction and the key elements that affect it. To this effect, this study explored the experiences of postnatal women in relation to labour services and investigated the factors that contribute to their overall satisfaction.

AIM

The study set out to explore factors influencing maternal satisfaction with labour care services in Ogbomoso, Oyo State, Nigeria. This study ultimately seeks to advance our understanding of this phenomenon to impact labour care and policy.

SETTING

The study was conducted among multiparous women who had their antenatal care and delivery in Ogbomoso, Oyo State, Nigeria.

METHODS

A qualitative study was performed using in-depth interviews among postnatal women.

RESULTS

The results revealed a number of variables that could affect the women's satisfaction with labour care, including the choice of health facility, healthcare providers, environment of the facility, assurance of privacy, treating patients with dignity, provision of needed amenities and having a well-planned postnatal care assessment.

CONCLUSION

The study revealed that the costs of care, the skill of the caregiver, the provision of confidential and dignified care, and the availability of supplies all have an impact on maternal satisfaction. Hospital administration should address these issues to enhance the experience of women and labour care services.Contribution: The study's findings provide insights that will inform strategies to improve the quality of care being provided to parturients in Nigeria.

Experiences of Impacted Foetal Head: Findings from a Pragmatic Focus Group Study of Mothers and Midwives

INTRODUCTION

We aimed to explore the lived experiences of caesarean birth complicated by impaction of the foetal head, for mothers and midwives.

METHODS

A pragmatic, qualitative, focus group study of mixed-participants was conducted, face-to-face. They were postpartum women (n = 4), midwives (n = 4), and a postpartum midwife (n = 1) who had experience of either providing care for impacted foetal head, and/or had experienced it during their own labour, in Fife, United Kingdom. Data were transcribed and were analysed using template analysis.

RESULTS

Three main themes emerged through analysis: (i) current knowledge of impacted foetal head; (ii) current management of impacted foetal head; and (iii) experiences and outcomes of impacted foetal head. Each theme was made up of various initial codes when data were analysed inductively. Finally, each theme could be overlaid onto the three core principles of the Tydeman Tube: (1) to improve outcomes for mother and baby in the second stage of labour; (2) to reduce the risk of trauma to mother and baby in complicated births; and (3) to increase respectful care for women in labour; thus allowing for a neat analytic template.

CONCLUSION

A lack of consensus regarding definition, management, and training were highlighted by the midwives. Women anticipated caesarean birth in late labour as straightforward and were therefore unaware of this potential complication. Women and midwives would welcome any new device to facilitate delivery of the impacted foetal head (IFH) as long as it is fully evaluated prior to widespread introduction. Women were not averse to being part of this evaluation process.

Peanut Ball Utilization Protocols in Women During Labour and Delivery: An Integrative Review

OBJECTIVE

This review aimed to assess the evidence available in the literature about the protocols for using peanut ball (PB) in women during labour and delivery.

DATA SOURCES

A systematic search was carried out by 2 independent researchers in the PubMed/MedLine, Web of Science, Embase, Cochrane and Scopus databases, and the reference lists were scanned for additional articles.

STUDY SELECTION

Search terms employed were selected from MeSH (Medical Subject Headings) and DeCS (Descriptors in Health Sciences) and combined in each database: "Pregnant Women" AND "Peanut Ball", "Peanut Ball" AND "Labor, Obstetric", as well as "Peanut Ball" AND "Parturition". There were no limits regarding the publication period or language. Studies that answered the following question were included: What are the protocols for the use of the PB in women during labour and childbirth described in the literature? Secondary studies were excluded. Disagreements were resolved by a third researcher.

DATA EXTRACTION

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guided this review. The authors prepared a standardized data extraction sheet to extract data and used the Mendeley software to organize the analyzed studies.

DATA SYNTHESIS

Ten studies made up the final sample of this review. Eight articles presented the protocol for using the PB: 2 studies included it after epidural analgesia and removed it at complete cervical dilation and effacement; 4 addressed the frequency of position changes during labour; and 3 reported data on maternal positions that were adopted. Five studies showed lower rates of cesarean delivery, and 2 reported that PB reduces the length of labour. Only 1 article associated the use of PB with the reduction of instrumental deliveries and perineal lacerations. One study showed a positive evaluation of parturients regarding the use of PB.

CONCLUSION

PB was associated with a reduction in cesarean and instrumental deliveries, and the length of labour. Despite its benefits, there is no standardized protocol for the use of PB, preventing it from predicting outcomes with its use.

Assessment of airway parameters in obstetric patients and comparing them at different phases in the perinatal period: A prospective observational study

Background and Aims

Airway changes occur in different stages of pregnancy. We aimed to evaluate the changes in the upper airway in obstetric patients during pregnancy, labour and after delivery using multiple airway indices and identify the predictive factors of these changes.

Methods

This observational study was conducted on 90 parturients aged >20 years, having monofoetal pregnancy. The patient's weight was noted, airway assessment including Mallampati grading (MPG), and thyromental distance (TMD), sternomental distance (SMD), neck circumference (NC) and Wilson's risk score were measured in the second trimester of pregnancy (T0), between 32 and 34 weeks of gestation (T1), at the time of admission for safe confinement, between 38 and 40 weeks of gestation (T2), 2 h after delivery of baby (T3) and, 24 h after delivery (T4). Unpaired t-test and analysis of variance test were applied.

Results

Changes in mean (standard deviation [SD]) weight, recorded from T0 to T2, were from 56.96 (10.77) to 65.322 (11.49) kg (P = 0.001). A rise of one or two grades in MPG was detected as the pregnancy progressed, and a decrease of one grade was noted after delivery. A significant decrease in mean (SD) TMD was noted from 6.88 (0.65) to 6.36 (0.62) cm from T0 to T2 (P = 0.001). SMD also decreased in a similar manner as TMD. NC increased from T0 to T3 and then decreased at T4 (P = 0.004).

Conclusion

Following the second trimester of pregnancy, MPG increased by either one or two grades, with a decrease in TMD and SMD and an increase in NC.

Childbearing with Hypermobile Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorders: A Large International Survey of Outcomes and Complications

One in 20 births could be affected by hypermobile Ehlers-Danlos syndrome or Hypermobility Spectrum Disorders (hEDS/HSD); however, these are under-diagnosed and lacking research. This study aimed to examine outcomes and complications in people childbearing with hEDS/HSD. A large online international survey was completed by women with experience in childbearing and a diagnosis of hEDS/HSD (N = 947, total pregnancies = 1338). Data were collected on demographics, pregnancy and birth outcomes and complications. Participants reported pregnancies in the UK (N = 771), USA (N = 364), Australia (N = 106), Canada (N = 60), New Zealand (N = 23) and Ireland (N = 14). Incidences were higher in people with hEDS/HSD than typically found in the general population for pre-eclampsia, eclampsia, pre-term rupture of membranes, pre-term birth, antepartum haemorrhage, postpartum haemorrhage, hyperemesis gravidarum, shoulder dystocia, caesarean wound infection, postpartum psychosis, post-traumatic stress disorder, precipitate labour and being born before arrival at place of birth. This potential for increased risk related to maternal and neonatal outcomes and complications highlights the importance of diagnosis and appropriate care considerations for childbearing people with hEDS/HSD. Recommendations include updating healthcare guidance to include awareness of these possible complications and outcomes and including hEDS/HSD in initial screening questionnaires of perinatal care to ensure appropriate consultation and monitoring can take place from the start.

What is Currently Understood About the Impact of Sexual Violence Activism for Higher Education Student Sexual Violence Survivors?

Objective: This systematic literature review maps the landscape of higher education and student sexual violence survivors who become involved in sexual violence activism. It was undertaken to understand what drives student sexual violence survivors to become activists, the negative and positive impacts of this activism on the students, how higher education institutions might work with sexual violence activists to foster effective prevention and response, and how activism has been negotiated by and within practice, policy and research. Method: A qualitative evidence synthesis methodology was used to identify research which examines drivers to and consequences of sexual violence activism for student activists. Searches across seven databases were conducted using six keywords combined in various ways, with further inclusion criteria of published in English between 2010 and 2020. Searches of grey literature were also carried out. Results: 28 sources met the inclusion criteria. Thematic analysis, conducted in NVivo, resulted in identification of four themes: survival from harm, community, labour in the personal made public and power between activists and institutions. Conclusions/Recommendations/Limitations: Inadequate institutional response was a key driver of student sexual violence activism. Activism had positive and negative impacts on the activists. Recommendations are that activists, institutions, researchers and policy makers work as coalitions to bring about enduring cultural change. Review limitations were the small number of studies in this field; additionally, they were dominated by US and UK perspectives.
