Investigation of the effect of pregnant women's childbirth-related Internet use on fear of childbirth

This research was carried out to examine the effect of childbirth-related Internet use by pregnant women on fear of childbirth (FOC). The descriptive study was conducted with 350 pregnant women who applied to the Outpatient Polyclinic of Gynaecology and Obstetrics. Of the pregnant women who used the Internet, 72.9% did so to research information about childbirth. The pregnant women used the Internet mostly to obtain information about coping with labour pain (43.4%), the delivery process (46.9%), the needs list at delivery (39.4%), about C-section/epidural analgesia for labour (26.8%), and about the environment of the delivery room (25.7%). It was determined that there was a statistically significant difference (p < .05) between the delivery-related video viewing status of the pregnant women, the mean score of the W-DEQ Version A (p < .05), and the FOC was lower in those who watched videos about delivery.IMPACT STATEMENTWhat is already known on this subject? Previous studies have shown that pregnant women frequently use the Internet as a source of information about childbirth.What do the results of this study add? The findings of this study reveal that watching videos and listening to or reading the narrations significantly affected the FOC.What are the implications of these findings for clinical practice or further research? Nurses who provide preconception and antenatal care should consider Internet use as a risk factor for FOC and should guide pregnant women to reliable sources.

Advancement in Partograph: WHO's Labor Care Guide

Worldwide, the partograph, also known as a partogram, is used as a labor monitoring tool to detect difficulties early, allowing for referral, intervention, or closer observations to follow. Despite widespread support from health experts, there are worries that the partograph has not yet fully realized its potential for enhancing therapeutic results. As a result, the instrument has undergone several changes, and numerous studies have been conducted to examine the obstacles and enablers to its use. Nevertheless, the partograph was widely embraced and has been a component of evaluating labor progress. Earlier it was also used as a standard method for monitoring labor progress. Even though it is widely used, there have been reports of usage and accurate execution rates. The WHO Labor Care Guide (LCG) was created so that medical professionals could keep an eye on the health of pregnant women and their unborn children during labor by conducting routine evaluations to spot any abnormalities. The tool intends to enhance women-centered care and encourage collaborative decision-making between women and healthcare professionals. The LCG is designed to be a tool for ensuring high-quality research centered on health, reducing pointless measures, and offering comfort measures.

Gender and Regionalization in North America: From NAFTA to CUSMA and Beyond?

The literature on world regions is largely gender-blind. This article suggests ways in which the study of regionalism can incorporate gender analysis, based on the case of North America. It argues that this can be done in three ways: through an examination of the gendered impact of regional integration; through an examination of how gender concerns are, or can be, mainstreamed into regional policies; and through research on new forms of feminist-inspired activism that may shape regional outcomes. After applying these perspectives to the case of North America and the new Canada-United States-Mexico Agreement, it argues that despite the failure of the Canadian government to achieve the inclusion of a gender chapter, the inclusion of language around gender discrimination in the labour chapter makes the new agreement a more effective (if still limited) tool for promotion of some forms of gender equality.

Towards a post-COVID geography of economic activity: Using probability spaces to decipher Montreal's changing workscapes

In March 2020, many workers were suddenly forced to work from home. This brought into stark relief the fact that urban economic activity is no longer attached to specific workplaces. This detachment has been analysed in research on organisations and workers, but has not yet been incorporated into concepts used to document and plan the economic geography of cities. In this article, three questions are explored by way of an original survey: first, how can a shift in the location of economic activity be measured at the urban scale whilst incorporating the idea that work is not attached to a single location? Second, what is the nature of the shift that occurred in March 2020? Third, what does this tell us about concepts that have underpinned the study of urban economic form by geographers and planners? Applying concepts developed in organisation studies and sociology, we operationalise the idea that economic activity happens across multiple spaces: it occurs within a probability space, and since March 2020 it has shifted within this space. To better understand and interpret the longer-term impact of this shift on cities - downtowns in particular - we draw upon interviews with people working from home.

Virtual reality is beneficial in decreasing pain in labouring women: A preliminary study

BACKGROUND

Women use a range of non-pharmacological pain relief methods to reduce labour pain intensity and to help manage labour pain.

AIMS

The purpose of this intervention study was to determine whether virtual reality would have an effect on labour pain intensity. Virtual reality has been shown to be effective in reducing pain in other acute pain settings.

MATERIALS AND METHODS

This study was an intervention study in labour in a cross-over within-subjects design (Clinical Trials Registry Number: ACTRN12618001776291P). Fourteen participants reported their pain and had their heart rate and blood pressure measured during active labour while using and not using virtual reality.

RESULTS

There were significantly lower reported pain scores (6.14 compared to 7.61, P < 0.001) and maternal heart rate (79.86 beats per minute compared to 85.57, P = 0.033) and mean arterial pressure (88.78 mmHg compared to 92.61 mmHg, P = 0.022) were lower when using virtual reality compared to when not using virtual reality during active labour.

CONCLUSION

This study makes an important contribution to the field of virtual reality in labour and birth. It is consistent with other recent findings of reduced pain in labour and links decreased pain scales to heart rate and blood pressure, the physiological markers of pain.

Psychometric Evaluation of the Malay Version of the Childbirth Experience Questionnaire (CEQ-My)

Negative childbirth experience may cause adverse psychological effects in postpartum mothers. The Childbirth Experience Questionnaire (CEQ) is a multidimensional tool designed to assess women’s perceptions of labour and birth. We aim to validate the Malay version of the CEQ (CEQ-My) and evaluate its psychometric properties. The previously published Malay-translated CEQ was reviewed by a panel of experts and underwent minor changes. The original visual analogue scoring (VAS) was changed to a numerical scale. The reliability and construct validity of CEQ-My was assessed using Cronbach’s alpha and exploratory analysis, respectively. Known-groups validation was conducted using the Mann−Whitney U test, whilst the inter-item correlations between CEQ-My and its subdomains were evaluated through Spearman’s correlation. The final analysis involved 246 women. The questionnaire was easy to understand and all women preferred numeric scoring to the VAS. Based on the principal component factor analysis, we deleted one item and rearranged the domain for four items. The twenty-one items CEQ-My demonstrated good reliability with Cronbach’s alpha of 0.77. Women who had spontaneous vaginal delivery demonstrated significantly greater CEQ-My scores than those who underwent operative delivery (p = 0.002). The domain of professional support was positively correlated to that of own capacity and participation (p-value of < 0.001 and 0.002, respectively). The CEQ-My is a valid and reliable instrument to assess Malaysian women’s childbirth experiences. The easy-to-use electronic version of CEQ-My will improve future research and ease data collection.

Reduced 'fates of the body' and 'production of value for others' in the global garment industry: Thinking with Berlant on eating and hunger during the COVID-19 pandemic

During the COVID-19 pandemic, suspended and laid off garment workers struggled on severely reduced incomes to meet the cost of food for themselves and their families. It is in this context of 'double crisis' that our commentary focuses on the diminished eating and reduced bodily fates of garment workers during the COVID-19 pandemic. We argue that thinking with Berlant encourages and supports scholars to contemplate and articulate how the 'production of value for others' can reduce the 'fates of the body' of those living and labouring at the sharp end of the capitalist system.

Induction of labour involving an amniotomy: Waiting compared to immediate oxytocin

During induction of labour (IOL), the optimal timing of oxytocin following amniotomy is unknown, with limited data to guide decision-making. This study aimed to see whether a 2-h delay after amniotomy before starting oxytocin during IOL reduced the use of oxytocin as well as other positive or negative impact. A propensity-score-matched cohort study assessed the maternal, neonatal and process outcomes of 1168 women (584 per group) comparing immediate oxytocin to a 2-h delay ('wait') after amniotomy. Women who waited were significantly less likely to receive oxytocin (61.2 vs 100%, P < 0.001) but more likely to receive antibiotics (14.7 vs 10.3%, P = 0.021), to be delivered by caesarean section (20.0 vs 14.6%, P = 0.013) and to be exclusively breastfeeding during discharge (77.2 vs 71.2%, P = 0.019). These findings provide further information for women and caregivers regarding the risks and benefits of a short delay before starting oxytocin.

Association between interleukin-6 levels in amniotic fluid after rupture of membranes during labour at term pregnancy and successful vaginal delivery: a prospective cohort study

We compared the mean interleukin-6 (IL-6) level in the amniotic fluid after rupture of membranes during labour at term pregnancy according to the delivery methods through prospective cohort study. Cases with premature rupture of membranes, multifetal pregnancy, and major congenital anomalies were excluded. Amniotic fluid was obtained from vaginal canal immediately after spontaneous rupture of membranes. A total of 47 cases were analysed, and 72.3% (34/47) had successful vaginal delivery. The mean concentration of IL-6 in the amniotic fluid was significantly higher in the vaginal delivery group than in the caesarean section group (5,229 pg/mL vs. 1,702 pg/mL, p = .022). The concentration of IL-6 from the amniotic fluid tended to increase as the cervical dilatation increased. The association between high IL-6 level (>2,500 pg/mL) and successful vaginal delivery was not significant after adjusting the degree of cervical dilatation in multivariate logistic regression analysis. IMPACT STATEMENTWhat is already known on this subject? Multiparity, active and strong uterine contractions, dilated cervical os, and the position of foetal head are known clinical factors affecting the successful vaginal delivery. There are few studies on markers for successful vaginal delivery in patients with labour.What do the results of this study add? The mean value of IL-6 concentration from the amniotic fluid collected from vagina immediately after rupture of membranes was significantly higher in the patients who had resulted in successful vaginal delivery than those who had failed.What are the implications are of these findings for clinical practice and/or further research? Measurement of IL-6 concentration in the amniotic fluid from vaginal canal in patients with labour might help to predict the successful vaginal delivery and shorten the time before decision of caesarean section.

Epileptic seizure control during and after pregnancy in Australian women

OBJECTIVES

To study factors that affected previous epileptic seizure control throughout pregnancy, during labour, and in the post-natal weeks.

MATERIALS & METHODS

Analysis of data concerning seizure freedom that was available at various stages of 2337 pregnancies in the Raoul Wallenberg Australian Pregnancy Register of Antiepileptic Drugs, mainly employing multiple variable logistic regression techniques.

RESULTS

Based on data available at the outset of pregnancy, the risk of seizure-affected that is, not seizure-free pregnancy was statistically significantly (p < .05) higher in pregnancies where there was previously uncontrolled epilepsy (78.1% vs. 20.8%) and focal epilepsy (51.3% vs. 39.7%), and decreased with later onset-age epilepsy (41.8% vs. 52.2% with onset before age 13 years), The risk did not differ between initially antiseizure medication (ASM)-treated or untreated pregnancies. For epilepsy receiving ASM therapy, 90.6% of 160 pregnancies of women with uncontrolled focal epilepsy that began before the age of 13 were seizure-affected. None of the above factors influenced the risk of seizures during labour, though having seizures during pregnancy increased the hazard (3.93 vs. 0.6%). Either ASM-treated pregnancy or labour being seizure-affected increased the risk of post-partum period seizures (33.0% vs. 6.67% for both stages being seizure-free). Use of particular ASMs had no statistically significant effect on the seizure control situation at any of the pregnancy stages studied.

CONCLUSIONS

Obtaining full seizure control before pregnancy appeared to be the main factor in maintaining seizure freedom during pregnancy, labour and the post-natal weeks.

Comparative evaluation of normal saline, 1/3-2/3, and ringer's lactate infusion on labour outcome, PH, bilirubin, and glucose level of the umbilical cord blood in nulliparous women with labour induction: a randomised clinical trial

This study aimed to compare the effects of infusion of normal saline, 1/3-2/3, and Ringer's lactate fluids on labour outcome, pH, bilirubin, and glucose level of umbilical cord blood. In this randomised clinical trial, 450 nulliparous women with Bishop score ˂5 and indication of pregnancy termination were randomly divided into three groups to receive normal saline, 1/3-2/3, or Ringer's lactate infusion at a rate of 125 mL/h for hydration, upon starting induction of labour. Results of this study indicated that the incidence of hypoglycaemia (p = .19), hyper bilirubinemia (p = .87) and acidosis (p = .10) was similar in neonates of the three groups. Also, there were no statistically significant differences between the three groups with regard to the duration of labour; glucose, bilirubin and pH level of cord blood; and mode of delivery. It can be concluded that infusion of Ringer's lactate, normal saline or 1/3-2/3 fluid during labour is not associated with different maternal or foetal/neonatal outcomes, and none of the fluids has superiority to the others.Impact statementWhat is already known on this subject? Several studies have been conducted on the association between type and volume of infused fluid on labour duration and neonatal outcomes. However, there has been some controversy.What do the results of this study add? This is the first study that has investigated the association between infusion of Ringer's lactate, normal saline or 1/3-2/3 fluid during labour with labour outcome and pH, bilirubin, and glucose level of the umbilical cord blood and results showed that these fluids have no effect on maternal or foetal/neonatal outcomes and also none of these fluids has superiority to the others.What are the implications of these findings for clinical practice and/or further research? Due to contradictory results of previous studies, further research with greater sample sizes and different fluids type and volumes may be needed to examine the association between infusion of fluids and neonatal and labour outcomes more precisely.

A survey of labour epidural practices at obstetric anesthesia fellowship programs in the United States

Purpose

Labour epidural analgesia (LEA) is an evolving field. Various neuraxial techniques and dosing regimens are available to the modern obstetric anesthesia provider, allowing for significant practice variability. To begin a search for consensus on optimal care, we sought to query fellowship training practices for LEA.

Methods

We conducted an electronic survey of institutions with American Council for Graduate Medical Education-accredited obstetric anesthesiology fellowship programs. We studied the frequency of epidural initiation techniques, including combined spinal epidural (CSE), dural puncture epidural, and epidural bolus. For maintenance techniques, we appraised the use of continuous epidural infusion, programmed intermittent bolus (PIEB), and patient-controlled epidural analgesia (PCEA).

Results

Of 40 institutions surveyed, we received 32 responses (80% response rate). Twenty-eight of 40 (70%) were included in the analysis. A plurality of institutions (12/28; 43%) preferred CSE, and among those who used CSE, 23/27 (85%) included intrathecal opioids. A majority of institutions used protocols with PIEB (55%), while almost all (92%) used PCEA. Most participants (88%) reported using dilute concentration maintenance infusions of 0.1% bupivacaine/ropivacaine or less.

Conclusion

Despite significant variability in LEA practice, some clear patterns emerged in our survey, including preference for opioid-containing CSE and maintenance with PIEB, PCEA, and dilute epidural solutions.

Obstetric-Neonatal Care during Birth and Postpartum in Symptomatic and Asymptomatic Women Infected with SARS-CoV-2: A Retrospective Multicenter Study

This study analyses the obstetric−neonatal outcomes of women in labour with symptomatic and asymptomatic COVID-19. A retrospective, multicenter, observational study was carried out between 1 March 2020 and 28 February 2021 in eight public hospitals in the Valencian community (Spain). The chi-squared test compared the obstetric−neonatal outcomes and general care for symptomatic and asymptomatic women. In total, 11,883 births were assisted in participating centers, with 10.9 per 1000 maternities (n = 130) infected with SARS-CoV-2. The 20.8% were symptomatic and had more complications both upon admission (p = 0.042) and during puerperium (p = 0.042), as well as transfer to the intensive care unit (ICU). The percentage of admission to the Neonatal Intensive Care Unit (NICU) was greater among offspring of symptomatic women compared to infants born of asymptomatic women (p < 0.001). Compared with asymptomatic women, those with symptoms underwent less labour companionship (p = 0.028), less early skin-to-skin contact (p = 0.029) and greater mother−infant separation (p = 0.005). The overall maternal mortality rate was 0.8%. No vertical transmission was recorded. In conclusion, symptomatic infected women are at increased risk of lack of labour companionship, mother−infant separation, and admission to the ICU, as well as to have preterm births and for NICU admissions.

Association between screening for antenatal depressive symptoms and delivery outcomes: The Born in Queensland Study

BACKGROUND

Evidence shows that depressive symptoms during pregnancy increase the risk of an intervention during delivery (induction, the use of forceps or vacuum, and caesarean sections (CS)). Many women with depression during pregnancy are not identified and therefore will not receive appropriate follow up of their symptoms. We hypothesised that routine screening for depressive symptoms during pregnancy could reduce detrimental consequences of depressive symptoms on delivery outcomes.

AIM

We explored the association between screening for depressive symptoms during pregnancy and delivery outcomes.

MATERIALS AND METHODS

A cross-sectional analysis of state-wide administrative data sets. The population included all women who delivered a singleton in Queensland between the July and December of 2015. Logistic regression analyses were run in 27 501 women (93.1% of the total population) with information in all variables. The following were the main outcomes: onset of labour, CS, instrumental vaginal delivery, and all operative deliveries (including both CS and instrumental vaginal deliveries).

RESULTS

Women who completed the screening had increased odds of a spontaneous onset of labour (adjusted odds ratio (aOR) 1.18; 95% CI 1.09-1.27) and decreased odds of an operative delivery (instrumental or CS) (aOR 0.88; 95% CI 0.81-0.96). Among women who had a vaginal delivery, those who completed the screening had decreased odds of having an instrumental delivery (aOR 0.84; 95% CI 0.74-0.97). Sensitivity analyses in women who did not have a formal diagnosis of depression showed similar results.

CONCLUSION

Our findings suggest that screening may decrease interventions during delivery in women with depressive symptoms.

Use of induction of labour and emergency caesarean section and perinatal outcomes in English maternity services: a national hospital-level study

OBJECTIVES

To assess the association between hospital-level rates of induction of labour and emergency caesarean section, as measures of "practice style", and rates of adverse perinatal outcomes.

DESIGN

National study using electronic maternity records.

SETTING

English National Health Service.

PARTICIPANTS

Hospitals providing maternity care to women between April 2015 and March 2017.

MAIN OUTCOME MEASURES

Stillbirth, admission to a neonatal unit, and babies receiving mechanical ventilation.

RESULTS

Among singleton term births, the risk of stillbirth was 0.15%; of admission to a neonatal unit 5.4%; and of mechanical ventilation 0.54%. There was considerable between-hospital variation in the induction of labour rate (minimum 17.5%, maximum 40.7%) and the emergency caesarean section rate (minimum 5.6%, maximum 17.1%). Women who gave birth in hospitals with a higher induction of labour rate had better perinatal outcomes. For each 5%-point increase in induction, there was a decrease in the risk of term stillbirth by 9% (OR 0.91; 95% CI 0.85 to 0.97) and mechanical ventilation by 14% (OR 0.86; 95% CI 0.79 to 0.94). There was no significant association between hospital-level induction of labour rates and neonatal unit admission at term (p>0.05). There was no significant association between hospital-level emergency caesarean section rates and adverse perinatal outcomes (p always >0.05).

CONCLUSIONS

There is considerable between-hospital variation in the use of induction of labour and emergency caesarean section. Hospitals with a higher induction rate had a lower risk of adverse birth outcomes. A similar association was not found for caesarean section.

Placental Inflammasome mRNA Levels Differ by Mode of Delivery and Fetal Sex

Parturition signals the end of immune tolerance in pregnancy. Term labour is usually a sterile inflammatory process triggered by damage associated molecular patterns (DAMPs) as a consequence of functional progesterone withdrawal. Activation of DAMPs recruits leukocytes and inflammatory cytokine responses in the myometrium, decidua, cervix and fetal membranes. Emerging evidence shows components of the inflammasome are detectable in both maternal decidua and placenta. However, the activation of the placental inflammasome with respect to mode of delivery has not been profiled. Placental chorionic villus samples from women delivering at term via unassisted vaginal (UV) birth, labouring lower segment caesarean section (LLSCS, emergency caesarean section) and prelabour lower segment caesarean section (PLSCS, elective caesarean section) underwent high throughput RNA sequencing (NextSeq Illumina) and bioinformatic analyses to identify differentially expressed inflammatory (DE) genes. DE genes (IL1RL1, STAT1, STAT2, IL2RB, IL17RE, IL18BP, TNFAIP2, TNFSF10 and TNFRSF8), as well as common inflammasome genes (IL1B, IL1R1, IL1R2, IL6, IL18, IL18R1, IL18R1, IL10, and IL33), were targets for further qPCR analyses and Western blotting to quantify protein expression. There was no specific sensor molecule-activated inflammasome which dominated expression when stratified by mode of delivery, implying that multiple inflammasomes may function synergistically during parturition. Whilst placentae from women who had UV births overall expressed pro-inflammatory mediators, placentae from LLSCS births demonstrated a much greater pro-inflammatory response, with additional interplay of pro- and anti-inflammatory mediators. As expected, inflammasome activation was very low in placentae from women who had PLSCS births. Sex-specific differences were also detected. Placentae from male-bearing pregnancies displayed higher inflammasome activation in LLSCS compared with PLSCS, and placentae from female-bearing pregnancies displayed higher inflammasome activation in LLSCS compared with UV. In conclusion, placental inflammasome activation differs with respect to mode of delivery and neonatal sex. Its assessment may identify babies who have been exposed to aberrant inflammation at birth that may compromise their development and long-term health and wellbeing.

Clinical algorithms for the management of intrapartum maternal urine abnormalities

AIM

To develop evidence-based clinical algorithms for management of common intrapartum urinary abnormalities.

POPULATION

Women with singleton, term pregnancies in active labour and immediate postnatal period, at low risk of complications.

SETTING

Healthcare facilities in low- and middle-income countries.

SEARCH STRATEGY

A systematic search and review were conducted on the current guidelines from WHO, NICE, ACOG and RCOG. Additional search was done on PubMed and The Cochrane Database of Systematic Reviews up to May 2020.

CASE SCENARIOS

Four common intrapartum urinary abnormalities were selected: proteinuria, ketonuria, glycosuria and oliguria. Using reagent strip testing, glycosuria was defined as ≥2+ on one occasion or of ≥1+ on two or more occasions. Proteinuria was defined as ≥2+ and presence of ketone indicated ketonuria. Oliguria was defined as hourly urine output ≤30 ml. Thorough initial assessment using history, physical examination and basic investigations helped differentiate most of the underlying causes, which include diabetes mellitus, dehydration, sepsis, pre-eclampsia, shock, anaemia, obstructed labour, underlying cardiac or renal problems. A clinical algorithm was developed for each urinary abnormality to facilitate intrapartum management and referral of complicated cases for specialised care.

CONCLUSIONS

Four simple, user-friendly and evidence-based clinical algorithms were developed to enhance intrapartum care of commonly encountered maternal urine abnormalities. These algorithms may be used to support healthcare professionals in clinical decision-making when handling normal and potentially complicated labour, especially in low resource countries.

TWEETABLE ABSTRACT

Evidence-based clinical algorithms developed to guide intrapartum management of commonly encountered urinary abnormalities.

Clinical algorithms for management of fetal heart rate abnormalities during labour

OBJECTIVE

To construct algorithms with a sequential decision analysis pathway for monitoring of the fetal heart rate and managing fetal heart rate bradycardia, late decelerations and tachycardia during labour.

POPULATION

Low-risk pregnant women in labour with singleton cephalic term pregnancies.

SETTING

Institutional births in low- and middle-income countries.

SEARCH STRATEGY

We sought relevant published clinical algorithms, guidelines and randomised trials/reviews by searching the Cochrane Library, PubMed and Google on the terms: "fetal AND heart AND rate AND algorithm AND (labour OR intrapartum)", up to March 2020.

CASE SCENARIOS

The two scenarios included were fetal heart rate bradycardia or late decelerations (potentially related to uterine rupture, placental abruption, cord prolapse, maternal hypotension, uterine hyperstimulation or unexplained) and fetal heart rate tachycardia (potentially related to maternal hyperthermia, infection, dehydration or unexplained). The algorithms provide pathways for definition, assessment, diagnosis, interventions to correct the abnormalities and ongoing monitoring leading to mode of birth, and linking to other algorithms in the series.

CONCLUSIONS

The algorithms provide a framework for monitoring and managing fetal heart rate bradycardia, late decelerations and tachycardia during labour. We emphasise the inherent diagnostic inaccuracy of fetal heart rate monitoring, the tendency to over-diagnose fetal compromise, the need to consider fetal heart rate information in the context of other clinical features and the need to engage in informed, shared, family-centred decision-making. We note the need for further research on methods of fetal assessment during labour including clinical fetal arousal testing and the rapid biophysical profile test.

TWEETABLE ABSTRACT

Decision analysis algorithms for fetal bradycardia, late decelerations and tachycardia highlight diagnostic limitations.

Clinical management of uterine contraction abnormalities; an evidence-based intrapartum care algorithm

AIM

To develop algorithms as decision support tools for identifying, managing and monitoring abnormal uterine activity during labour.

POPULATION

Women with singleton, term (37-42 weeks) pregnancies in active labour at admission.

SETTING

Institutional birth settings in low- and middle-income countries (the algorithm may be applicable to any health facility).

SEARCH STRATEGY

PubMed was searched up to January 2020 using keywords. We also searched The Cochrane Library, and international guidelines from World Health Organization (WHO), National Institute for Health and Care Excellence (NICE), American College of Obstetricians and Gynecologists (ACOG) and French College of Gynaecologists and Obstetricians (CNGOF).

CASE SCENARIOS

Algorithms were developed for two case scenarios: uterine hypoactivity and excessive uterine contractions. Key themes in the algorithm are: diagnosis, identification of probable causes, assessment of maternal and fetal condition and labour progress, monitoring and management.

CONCLUSION

The algorithms for uterine hypoactivity and excessive uterine contractions have been developed to facilitate safe and effective management of abnormal uterine activity during labour. Research is needed to assess the views of healthcare professionals and women accessing healthcare to explore the feasibility of implementing these algorithms, and impact on labour outcomes.

TWEETABLE ABSTRACT

An evidence-based algorithm to support clinical management of abnormal uterine activity during labour.

Clinical management of deviations in maternal temperature during labour and childbirth: an evidence-based intrapartum care algorithm

AIM

The development of an evidence-based algorithm for the clinical management of deviations in maternal temperature during labour and childbirth.

POPULATION

Pregnant women at any stage of labour, with singleton, term (37-42 weeks) pregnancies at low risk of developing complications.

SETTING

Health facilities in low- and middle-income countries.

SEARCH STRATEGY

We searched for international guidelines and prioritised WHO guidelines. In addition, we searched for other sources of evidence in the Cochrane Database of Systematic Reviews, EMBASE, MEDLINE and CINAHL until June 2020. Studies were prioritised according to the hierarchy of evidence.

CASE SCENARIOS

Two case scenarios were identified: maternal hyperthermia and hypothermia. We developed a single algorithm including both, due to commonalities in diagnosis, monitoring and management of underlying causes. The underlying conditions covered in the pathway include maternal sepsis and infection, chorioamnionitis, pyelonephritis, lower urinary tract and respiratory infections. Key decision points in the algorithm are suspicion of condition, definition, differential diagnosis, monitoring and management.

CONCLUSIONS

We present an evidence-based algorithm to assist healthcare professionals in making decisions about appropriate clinical management of deviations in maternal temperature. Research is needed to assess the views of healthcare professionals and women accessing healthcare on the feasibility of implementing the algorithm.

TWEETABLE ABSTRACT

An evidence-based intrapartum care algorithm to support management of deviations in maternal temperature in labour and childbirth. #sepsis #maternitycare.

Management of maternal pulse and blood pressure abnormalities during labour and childbirth: evidence-based algorithms for intrapartum care decision support

AIMS

To develop evidence-based clinical algorithms for assessment and management of abnormal maternal pulse and blood pressure during the intrapartum period.

POPULATION

Low risk singleton, term, pregnant women in labour.

SETTING

Institutional births in low- and middle-income countries.

SEARCH STRATEGY

A review of the literature was performed to retrieve evidence-based guidelines, systematic reviews, and papers on maternal pulse and blood pressure during labour. We searched a number of international clinical guidelines and PubMed using the corresponding key terms in November 2018 and updated the search in May 2020.

CASE SCENARIOS

Four common intrapartum case scenarios of abnormal pulse and blood pressure were identified for which algorithms were developed: hypertension, hypotension, tachycardia and bradycardia. Algorithms were constructed after reviewing guidelines and relevant papers, with input from a panel of experts. Thresholds for upper and lower limits of normal maternal pulse and blood pressure measurements are defined, evidence-based interventions for the initial management of abnormal parameters are described (resuscitation and monitoring) and guidance is provided on exploration of the potential causes for each case scenario, with links to pathways for their management.

CONCLUSIONS

Evidence-based algorithms to support the identification, and management of deviations in pulse and blood pressure during intrapartum care have been developed for hypertension, hypotension, tachycardia and bradycardia. The algorithms focus on initial resuscitation and monitoring, with an exploration of causes and early identification of underlying maternal conditions. These algorithms will help provide a standardised approach to investigation and management of these abnormal parameters to guide clinical practice.

TWEETABLE ABSTRACT

Algorithms for abnormal maternal pulse and blood pressure during labour allow standardised approach to early identification and management of complications.

Automated infrastructure: COVID-19 and the shifting geographies of supply chain capitalism

In recent years, geographers have evinced how infrastructure constitutes the bedrock of supply chain capitalism and its oppressions. This article interrogates how advanced automation - comprising robotics, artificial intelligence and software - is poised to politicize this infrastructural space further on the heels of the COVID-19 pandemic. Reflecting on COVID-19 developments, the article shows how logistics is turning to advanced automation to drive productivity outside labour, spur self-service consumption through digital technologies and contest labour's future. As automated infrastructure threatens to take hold, a configuration of exchange that increasingly places labour, but not profits, outside of capital's circulations will need to be challenged.

Birth with synthetic oxytocin and the risk of being overweight or obese during childhood

BACKGROUND

Despite the importance of oxytocinergic signalling for satiety regulation and energy balance, the impact of exposure to synthetic oxytocin during childbirth on obesity during childhood remains unknown.

OBJECTIVES

To examine the association between oxytocin exposure during labour and the risk of being overweight or obese during childhood.

METHODS

Synthetic oxytocin exposure data of mothers from the Danish Medical Birth Registry were linked with self-reported anthropometric data of their children from the Danish National Birth Cohort (5 months-11 years of age). Multinomial logistic regression and latent class growth analyses were performed to determine the association between oxytocin exposure and obesity during childhood.

RESULTS

With the exception of the normal weight-to-overweight group between ages 5 and 12 months, none of the other analyses revealed a significant association between synthetic oxytocin use and the risk of being overweight until the age of 11 years. Furthermore, latent class growth analysis did not reveal an association between oxytocin exposure at birth and the risk of being overweight or obese during childhood.

CONCLUSIONS

Our analysis of a large cohort of children who varied in their synthetic oxytocin exposure status at childbirth did not reveal an association between oxytocin exposure and the risk of childhood overweight/obesity.

Single-centre survey of women reflecting on recent experiences and preferences of oral intake during labour

BACKGROUND

Consensus-based recommendations guiding oral intake during labour are lacking.

AIMS

We surveyed women at a tertiary women's hospital about preferences for and experiences of oral intake during labour, gastrointestinal symptoms during labour and recalled advice about oral intake.

MATERIALS AND METHODS

Women who experienced labour completed a postpartum survey with responses as free text, yes-no questions and five-point Likert scales. We identified demographic data and risk factors for surgical or anaesthetic intervention at delivery from medical records. We summarised free text comments using conventional content analysis.

RESULTS

One hundred and forty-nine women completed the survey (47% response rate). Their mean (SD) age was 31 (four) years, birthing at median gestation of 39 weeks (interquartile range: 38-40). One hundred and twenty-two (83%) and 44 (30%) women strongly agreed or agreed they felt like drinking and eating respectively during labour. Ninety women (61%) reported nausea and 47 women (32%) reported vomiting in labour. Forty-one women (28%) did not receive advice on oral intake during labour. Maternal risk factors for surgical intervention were identified in 72 (48%) women and fetal risk factors in 27 (18%) women. Thirty-one women (21%) delivered by emergency caesarean section.

CONCLUSION

Pregnant women received variable advice regarding oral intake during labour, from variable sources. Most women felt like drinking but not eating during labour. Guidelines on oral intake in labour may be beneficial to women, balancing the preferences of women with risks of surgical intervention.

Epidural labour analgesia and autism spectrum disorder: is the current evidence sufficient to dismiss an association?

Findings from a population-based study using a sibling-matched analysis published in this issue of the British Journal of Anaesthesia indicate that epidural labour analgesia is not associated with an increased risk of autism spectrum disorder. These findings are consistent with those from three other population-based studies that used similar methodological approaches. Cumulatively, these robust, high-quality epidemiological data support the assertion that there is no meaningful association between epidural labour analgesia and autism spectrum disorder in offspring.
