Regional anaesthetic techniques in 14 Slovenian obstetric units between 2013 and 2021: where are we and where are we going?

Background: The use of regional anaesthetic techniques for caesarean section and labour analgesia is necessary for quality-driven obstetric anaesthesia as required by European minimum standards for obstetric analgesia and anaesthesia departments, which were issued by the European Society of Anaesthesiology and Intensive Therapy in 2020. The aim of this article is to evaluate the rate of caesarean sections performed using regional anaesthetic techniques and the rates of epidural, remifentanil-PCA, and meperidine analgesia for managing labour pain across the 14 Slovenian obstetric units, respectively. Methods: Data from the Slovenian National Perinatal Information System (NPIS) from 2013 to 2021 were analysed. Results: Spinal anaesthesia was used as a primary anaesthetic method (> 50% of elective caesarean sections) in a half of Slovenian obstetric units. For emergency caesarean sections, regional anaesthetic methods (spinal and epidural) were used in > 50% parturients in 3 obstetric units. Eight obstetric units had an epidural rate of >10%. The use of epidural analgesia has progressively increased in 9 of 14 obstetric units. Remifentanil has been routinely used in 6 obstetric units. Accordingly, the consumption of meperidine has dropped in all but one obstetric unit in Slovenia. Conclusion: In the past decade, considerable progress has been observed in obstetric anaesthesia practice in Slovenia. This is evident from the increased use of regional anaesthesia for caesarean section and labour analgesia. However, there are considerable discrepancies in anaesthetic practices between different obstetric units in Slovenia, a situation the parturients should be informed of well in advance to be able to choose the obstetric unit according to their labour and delivery preferences. In order to avoid the differences in the quality and accessibility of anaesthetic practice between units, it is necessary to increase the number of anaesthesiologists involved in obstetric anaesthesia to ensure 24/7 service of labour analgesia to be able to fulfill minimum European standards for obstetric analgesia and anaesthesia departments.

Nurses' perception of epidural services in a Johannesburg academic setting.

Labour pain is associated with detrimental maternal and foetal physical and psychological effects. Labour analgesia is a basic right for all women and labour epidural analgesia has been accepted as the gold standard for providing such, with reported improvement in patient satisfaction. In South Africa, studies have shown that labour epidural rates are low. At an academic hospital in Johannesburg, a 24-h labour epidural service combined with an awareness campaign and educational programme (LEAP) was initiated with the aim of improving labour epidural rates. Results showed a short-lived uptake with a subsequent decline. This study explored the experiences of labour ward nursing staff regarding the labour epidural service at this academic hospital including perceived limitations and possible recommendations regarding improving service provision. A qualitative, descriptive and exploratory study was conducted. Purposive sampling was used with semistructured, audio-recorded individual interviews, thematic analysis was performed using Braun and Clarke's six-phase approach. The key theme is required education and supervision of epidural insertion (see page 3), management of childbirth and challenges related to epidural service provision. A positive sentiment was expressed by the participants; however, deficiencies in the service such as shortages of experienced personnel, work constraints and insufficient training may be affecting service sustainability. Further studies are recommended to form guidance towards the development and implementation of interventions to improve service delivery.Contribution:Provision of continual training and increased staffing of healthcare personnel will help improve the sustainability of the labour epidural service.

Peripartum anesthesia management and outcomes of patients with congenital heart disease: a single-center retrospective analysis (2009–2023)

BackgroundAdvances in medicine have enabled more patients with congenital heart disease (CHD) to become pregnant. However, these patients face significant challenges during the peripartum period. Current peripartum anesthesia guidelines for CHD patients mainly rely on case reports and small series. MethodsIn this retrospective study at a high-volume tertiary care center, we analyzed peripartum anesthetic approaches, postpartum hemorrhage (PPH) incidence, and maternal outcomes in CHD patients stratified by the modified World Health Organization (mWHO) classification. ResultsAmong 85 473 deliveries between 2009 and 2023, 409 occurred in 282 patients with CHD. Cesarean deliveries were significantly more frequent in mWHO class III, p=0.005. Labor epidural analgesia was the most common analgesic modality for vaginal deliveries (epidural rate was 71.1% with no differences between mWHO classes). Anesthesia management for cesarean deliveries varied significantly by class p<0.001. While spinal anesthesia was predominant in classes I and II, combined spinal-epidural anesthesia was more common in class III. PPH incidence was 6.4%, with no significant difference across classes, and no association was found between mWHO class severity and PPH risk (OR 0.97; 95% CI; 0.93 to 1.02, p=0.2). Higher mWHO classes correlated with significantly higher intensive care unit (ICU) admission rates, longer hospital stays, and one-year cardiac hospitalizations. ConclusionIn this retrospective study on the peripartum anesthetic management and outcomes of CHD patients stratified by mWHO class, cases with greater mWHO class were more likely to deliver preterm, by cesarean delivery, with a combined spinal-epidural anesthetic and an arterial line placement for that cesarean delivery. They overall had a longer hospital stay and were more likely to be admitted to the ICU. However, the overall risk of PPH did not increase with mWHO class severity.

Patient Decision Making Surrounding Epidural Use in Labor

Introduction/Objectives: Labor is thought to be one of the most painful experiences in a woman’s life, similar to pain caused by complex regional pain syndromes. Epidural analgesia has been proven to provide excellent pain relief, and many women in the United States choose this during their labor course. The decision to use, or not to use, neuraxial analgesia is complex and multifactorial, and has historically generated debate amongst patients and obstetric providers. In addition, many patients will also change their minds about desiring an epidural in labor during their admission to Labor &amp; Delivery based on various factors encountered. This study aimed to determine the number of patients who change their mind about epidural in labor. We also aimed to characterize the factors involved in patients’ decision about epidural analgesia during labor and to determine if these factors change throughout the labor and delivery course. Methods: This study was a single-center, non-randomized, cross-sectional study that was performed at Loyola University Medical Center in the Labor &amp; Delivery unit. The study population included all full-term nulliparous patients that were admitted to Labor &amp; Delivery for full term labor or induction of labor. Patients were eligible if they were 18 years of age or older, and able to read, speak, and complete the study questionnaire in English. Exclusion criteria included previous vaginal delivery, contraindication to vaginal delivery, no plan to deliver during admission, and contraindication to epidural analgesia. The patients completed one questionnaire about preferences for epidural and influencing factors prior to delivery, and one questionnaire after delivery with similar questions. Demographics were collected, as well as data about complications and details of their labor and delivery course. Results: A total of 199 patients completed the study. The epidural rate was higher in patients who planned to receive it (n = 141/144 or 97.9%) than in patients who did not plan to receive an epidural (n = 49/55 or 89.1%). Further, there was significant discordance between patients’ plans for an epidural and receipt of the medication. That is, only three (1.5%) patients who planned to receive an epidural did not receive one. Conversely, 49 (24.6%) patients who did not plan to receive an epidural received one. Compared to patients who did not plan to receive an epidural, those who planned to receive the medication reported that their OBGYN physician (OR = 3.31, 95% CI: 1.80 – 6.06; p &lt; .001), Anesthesiology physician (OR = 2.73, 95% CI: 1.50 – 4.96; p = .001), and labor nurse (OR = 2.50, 95% CI: 1.38 – 4.53; p =.002) were more important sources of information. Further, when compared to patients who did not plan to receive an epidural, those who planned to receive the medication reported they wanted to be more comfortable during the course of labor (OR = 4.84, 95% CI: 2.50 – 9.39; p &lt; .001), that receiving an epidural would make their labor experience more enjoyable (OR = 27.17, 95% CI: 11.72 – 63.00; p &lt; .001), and that getting an epidural was safe (OR = 5.91, 95% CI: 2.96 – 11.80; p &lt; .001). Conclusions: In conclusion, this study found that the majority of patients in our study population chose to receive an epidural in labor, regardless of their plans at the start of their admission. The most important factors in the decision were discussions with the OBGYN and Anesthesiology physicians. Patients who decided to receive an epidural, despite planning not to, reported that they wanted to be more comfortable during their labor course and that receiving an epidural would make their labor experience more enjoyable.

Global Issues in Obstetric Anesthesia: Perspectives From South Africa, Japan, China, Latin America, and North America

(Int J Obstet Anesth. 2023:54:103648) Anesthesia provision varies worldwide, and obstetric anesthesia in particular is highly variable. The first country discussed in this article is South Africa, which is classified as a low-income to middle-income country. South Africa has high patient mortality related to cesarean delivery. The epidural rates for labor in South Africa are &lt;5%, which is considered extremely low. Approximately one-third of maternal deaths investigated occurred following the administration of spinal anesthesia. In South Africa, it is 3 times more likely for maternal mortality to occur following cesarean delivery than vaginal birth. The mortality rates following a cesarean delivery in South Africa are also 50 times higher than in other regions of the world. Training has been implemented to reduce these statistics, although the level of preparedness following this training has been questioned.

Accidental dural puncture during epidural blood patch: a narrative review

Whilst performing an epidural blood patch (EBP) to treat post dural-puncture headache following accidental or intentional dural puncture, the risk of a subsequent accidental dural puncture (ADP) is commonly quoted as 1%. However, a recent review reported only three documented cases. It seems likely that this complication is more common than is acknowledged, yet there is a paucity of literature and an absence of any guidance as to how to proceed in practice. This review addresses three unanswered questions regarding ADP during EBP: what is the incidence; what are the immediate clinical consequences; and what is the optimal clinical management?The incidence may reasonably be estimated to be 0.5–1%. Even on large units, this complication will not be experienced by every consultant anaesthetist during their career. It is likely to occur 20–30 times per year in the United Kingdom, and in greater numbers in those countries with higher epidural rates. Immediately re-attempting an EBP at a different level may be a reasonable management approach which has high efficacy, and is without clear evidence of significant harm. However, the limited evidence means that the risks are poorly characterised, and more data may lead to alternative conclusions.There is uncertainty amongst obstetric anaesthetists about how to manage ADP during EBP. More data and pragmatic guidance, which evolves with further evidence, will ensure optimal care for patients suffering this compound iatrogenic complication.

The effectiveness of skilled breathing and relaxation techniques during antenatal education on maternal and neonatal outcomes: a systematic review

BackgroundSeveral studies have investigated the relationship between antenatal education classes and pregnancy outcomes. These studies have shown positive effects on mothers, such as a lower epidural rate in the intervention groups. However, until now, the impact on outcomes for mothers and newborns of antenatal education classes that focus on breathing and relaxation techniques has not been examined.AimInvestigate the effects of skilled breathing and relaxation techniques provided in antenatal education classes on maternal and neonatal birth outcomes.MethodsThe protocol for this study was registered with PROSPERO (ID: CRD42020192289). A systematic literature search was undertaken and completed in January 2022, using the databases MEDLINE, CINAHL, clinicalTrials.gov, Cochrane Library, Embase and MIDIRS according to a priori formulated PICO criteria: population (pregnant women), intervention (antenatal education classes with integrated breathing and relaxation techniques), comparison (antenatal education classes that do not include skilled breathing and relaxation techniques), and outcome (maternal and neonatal outcomes). The quality of the studies was assessed by two reviewers using the standardised instruments RoB 2 and ROBINS-I.ResultsTen studies were included in this review, nine randomised controlled trials and one quasi-experimental study. The results indicate that skilled breathing and relaxation techniques may positively influence self-efficacy, the need for pharmacological support, specifically the use of epidural anaesthesia, and the memory of labour pain. No effects were found in relation to predefined neonatal outcomes. The quality of evidence on maternal and neonatal outcomes is inconsistent across studies, as different antenatal education classes with varying interventions, including breathing and relaxation techniques, were offered in the studies.ConclusionsWomen who attended an antenatal education class with breathing and relaxation techniques appear to benefit from the intervention. This applies to the practical implementation and use of breathing and relaxation techniques during labour, increased self-confidence and self-efficacy, and a increased feeling of being in control during labour. This demonstrates the importance of information provision and a focus on breathing and relaxation techniques in antenatal education.

Are There Similarities in Pregnancy Complications and Delivery Outcomes among Sisters?

This retrospective cohort study evaluated pregnancy outcomes and similarities between pairs of nulliparous sisters with a singleton fetus who delivered between 2013 and 2020. The "Sister-1 group" was defined as the sibling who delivered first, while the "Sister-2 group" included the siblings who gave birth after Sister-1. Obstetrical complications and delivery outcomes were compared. The relative risk for recurrence of a complication in Sister-2 was calculated. The study included 743 sister pairs. There were no between-group differences in maternal BMI, gestational age at delivery, gravidity, smoking, or epidural rates. The Sister-2 group was older than the Sister-1 group (26.4 ± 5 vs. 25.8 ± 4.7 years, respectively, p = 0.05). Higher birthweights and more large-for-gestational-age infants characterized the Sister-2 group compared with the Sister-1 group (3241 ± 485 g vs. 3148 ± 536 g, p &lt; 0.001 and 7.7% vs. 4.8%, p = 0.025, respectively). There were no between-group differences in the rate of small-for-gestational-age, gestational diabetes, hypertensive disorders, pre-term births, vacuum extraction, or cesarean deliveries. Logistic regression analysis found that if Sister-1 underwent vacuum extraction, her sibling had an increased risk for vacuum delivery (adjusted RR 3.03, 95% CI 1.4-6.7; p = 0.003) compared with those whose sibling (Sister-1) did not. There was a three-fold risk of vacuum extraction delivery between sisters. This finding could be related to biological inheritance, environmental factors, and/or psychological issues that may affect similarities between siblings' delivery outcomes.

The impact of withholding nitrous oxide in labour during the COVID-19 pandemic on maternal and neonatal outcomes.

Nitrous oxide is commonly used in Australia for labour analgesia. Its use in labour is potentially associated with aerosol generation. During the first wave of the COVID-19 pandemic of 2020, nitrous oxide was suspended on many birthing units to reduce the risk of transmission. We aimed to determine the impact of withholding nitrous oxide for labour analgesia, during the COVID-19 pandemic, on epidural rates, opioid analgesia use, and maternal and neonatal outcomes. Withholding nitrous oxide for labour analgesia did not alter epidural rates but did significantly increase opioid analgesia use. Caesarean section rates, post-partum blood loss and neonatal APGAR scores did not change.

Accidental epidural catheter removal rates and strength required for disconnection: a retrospective cohort and laboratory study

BackgroundEpidural catheters are associated with certain risks such as accidental epidural catheter removal, including dislodgement and disconnection. Globally, neuraxial connector designs were revised in 2016 to provide new standardization aimed at decreasing the frequency of misconnections during the administration of medications. However, no studies have investigated accidental epidural catheter removal after the revised standardization. This study aimed to examine differences in dislodgement and disconnection rates associated with different catheter connector types, and to investigate the linear tensile strength required to induce disconnection.MethodsThis retrospective cohort study included adult patients who underwent elective surgery and received patient-controlled epidural analgesia. Patients were divided into groups according to the type of catheter connection used: old standard, new standard, and new standard with taping groups. Furthermore, we prepared 60 sets of epidural catheters and connectors comprising 20 sets for each of the old, new, and taping groups, and used a digital tension meter to measure the maximum tensile strength required to induce disconnection.ResultsThis clinical study involved 360, 182, and 378 patients in the old, new, and taping groups, respectively. Dislodgement rates did not differ statistically among the three groups, while there was a significant difference in disconnection rates. Propensity score matching analysis for disconnection rates showed no difference between the old and new groups (2.8% vs. 4.5%, p = 0.574), while the new group had higher rates than the taping group (6.5% vs. 0%, p = 0.002). This laboratory study identified that a tensile strength of 12.41 N, 12.06 N, and 19.65 N was required for disconnection in the old, new, and taping groups, respectively, and revealed no significant difference between the new and old groups (p = 0.823), but indicated a significant difference between the new and taping groups (p < 0.001).ConclusionsThis clinical study suggested that dislodgement rates did not change among the three groups. Both clinical and laboratory studies revealed that disconnection rates did not change between the old and new connectors. Moreover, as a strategy to prevent accidents, taping the connecting points of the catheter connectors led to an increase in the tensile strength required for disconnection.

Model of care and chance of spontaneous vaginal birth: a prospective, multicenter matched-pair analysis from North Rhine-Westphalia

BackgroundAdvantages of midwife-led models of care have been reported; these include a higher vaginal birth rate and less interventions. In Germany, 98.4% of women are giving birth in obstetrician-led units. We compared the outcome of birth planned in alongside midwifery units (AMU) with a matched group of low-risk women who gave birth in obstetrician-led units.MethodsA prospective, controlled, multicenter study was conducted. Six of seven AMUs in North Rhine-Westphalia participated. Healthy women with a singleton term cephalic pregnancy booking for birth in AMU were eligible. For each woman in the study group a control was chosen who would have been eligible for birth in AMU but was booking for obstetrician-led care; matching for parity was performed.Mode of birth was chosen as primary outcome parameter. Secondary endpoints included a composite outcome of adverse outcome in the third stage and / or postpartum hemorrhage; higher-order obstetric lacerations; and for the neonate, a composite outcome (5-min Apgar < 7 and / or umbilical cord arterial pH < 7.10 and / or transfer to specialist neonatal care). Statistical analysis was by intention to treat. A non-inferiority analysis was performed.ResultsFive hundred eighty-nine case-control pairs were recruited, final analysis was performed with 391 case-control pairs. Nulliparous women constituted 56.0% of cases. For the primary endpoint vaginal birth superiority was established for the study group (5.66%, 95%-CI 0.42% – 10.88%). For the composite newborn outcome (1.28%, 95%-CI -1.86% - -4.47%) and for higher-order obstetric lacerations (2.33%, 95%-CI -0.45% - 5.37%) non-inferiority was established. Non-inferiority was not present for the composite maternal outcome (-1.56%, 95%-CI -6.69% - 3.57%). The epidural anesthesia rate was lower (22.9% vs. 41.1%), and the length of hospital stay was shorter in the study group (p < 0.001 for both).Transfer to obstetrician-led care occurred in 51.2% of cases, with a strong association to parity (p < 0.001). Request for regional anesthesia was the most common cause for transfer (47.1%).ConclusionOur comparison between care in AMU and obstetrician-led care with respect to mode of birth and other outcomes confirmed the superiority of this model of care for low-risk women. This pertains to AMU where admission and transfer criteria are in place and adhered to.

Estimating Obstetric Anaesthesia Workload: Number of Deliveries Compared to Time-Based Workload.

Number of deliveries is utilised to estimate obstetric anaesthesiologist workload; however, this may not reflect true workload. The goal of this analysis was to assess if including type of procedure, time required and length of each shift would better predict clinical workloads. We queried the electronic medical records at a high volume, academic centre for 12 consecutive months of maternal deliveries. Data extracted included delivery type, analgesic/anaesthetic procedure and whether delivery occurred during weekday, weeknight or weekend shifts. To generate an hourly comparison of shifts of varying duration, procedures were divided by the number of hours per shift. To calculate obstetric anaesthesiology time-based workload, delivery type was multiplied by estimated time associated with the analgesic/anaesthetic procedure. A total of 4,598 deliveries occurred in the 12-month study period. The caesarean delivery rate was 32%, and labour epidural rate was 85%. 1,564 anaesthetic procedures occurred during weekdays and 2,557 occurred during the weeknights and weekends. After accounting for the duration of each procedure and hours per shift, mean 6 standard deviation time-based workload ratio was 0.68 6 0.12 on weekdays versus 0.36 6 0.07 on weeknights and weekends. Relative workload based on deliveries alone suggests 41% less workload during the weekday, whereas accounting for duration of each procedure and hours per shift resulted in an 89% greater workload on weekday shifts. The study highlights the importance of considering analgesic/anaesthetic procedures and estimates of time taken to perform them, not just number of deliveries when considering obstetric anaesthesiology workload.

P.60 A one-year analysis of labour epidural top-ups and failure rates for operative intervention on delivery suite

Labour epidurals in Gauteng Province, South Africa

Background. Inadequately controlled labour pain is associated with numerous deleterious physiological and psychological effects. Epidural labour analgesia is accepted as the gold standard. Objectives. To establish the frequency of labour epidural analgesia for vaginal and caesarean section delivery in Gauteng Province (GP) private and public hospitals. Methods. GP maternity hospitals belonging to the three largest private hospital groups, and public academic, tertiary, regional and district maternity hospitals, were approached for inclusion in the study. A total of 24/47 private hospitals and 21/26 public hospitals agreed to participate in the present study and data from these hospitals were included in the data analysis. This was a retrospective study, and the delivery statistics and registers for 2015 were examined from all participating hospitals. Consecutive convenience sampling was applied. Results. A total of 3 560 labour epidurals were placed in the 45 participating hospitals in GP in 2015. About two-thirds (62%; n =2 208) of these labour epidurals were placed in the private sector. The median (interquartile range (IQR)) annual epidural frequency for all participating private hospitals was 6% (1.37 - 8.42). Only two public hospitals in GP were able to offer labour epidural services in 2015 and the annual proportion of deliveries with epidural placement was 4.1%. Both hospitals were academic hospitals affiliated with a single university. Conclusion. Similar to other developing countries, the labour epidural rates in GP hospitals were well below international labour epidural rates in 2015. This lack of service provision may be compromising patient care as well as the training of healthcare professionals.

Why is the labor epidural rate low and cesarean delivery rate high? A survey of Chinese perinatal care providers.

China has a high cesarean delivery (CD) and low labor epidural analgesia (LEA) rate. This online survey was conducted to explore the reasons behind this phenomenon and potential solutions. A voluntary, anonymous survey was distributed via both WeChat and professional websites for 4 months amongst groups of Chinese perinatal professionals. Data was collected and analyzed using a Chi-square test and presented as percentages of respondents. 1412 respondents were recorded (43% anesthesiologists, 35% obstetricians, 15.5% midwives or labor and delivery nurses, and 6.5% others), and 1320 respondents were care providers. It was found that 82.7% (1092/1320) of the provider respondents used CD per patient request in fear of lawsuits or yinao/yibao and 63.4% (837/1320) used CD for respecting superstitious culture. The number one reason (noted by 60.2% (795/1320) of all the three specialties) for low LEA use was lack of anesthesia manpower without statistical difference among specialties. The most recommended solution was increasing the anesthesia workforce, proposed by 79.8% (1053/1320) of the three specialties. However, the top solution provided by the two non-anesthesia specialties is different from the one proposed by anesthesiologists. The later (83%, 504/606) suggested increasing the incentive to provide the service is more effective. The answers to questions related to medical knowledge about CD and LEA, and unwillingness of anesthesiologists, parturients and their family members to LEA were similar for the most part, while the opinions regarding low LEA use related to poor experiences and unwillingness of obstetricians and hospital administrators were significantly divided among the three specialties. In the providers' point of view, the unwillingness to LEA from parturient's family members was the most salient (26.1%, 345/1320), which is more than all care providers, hospital administrators, and parturients themselves (16.8%, 222/1320). The reasons for high CD rate and low LEA use are multifactorial. The sociological issues (fear of yinao/yibao and superstitious culture) were the top two contributing factors for the high CD rate in China, while lack of anesthesia manpower was the top response for the low LEA use, which contributes to its being the most recommended solution overall from the three specialties. An incentive approach to providers is a short-term solution while training more perinatal care providers (especially among anesthesiologists and midwives), improving billing systems, and reforming legal systems are 3 systemic approaches to tackling this problem in the long-term.

Obstetric anesthesia services in Israel snapshot (OASIS) study: a 72 hour cross-sectional observational study of workforce supply and demand

BackgroundWe planned an observational study to assess obstetric anesthesia services nationwide. We aimed to assess the effect of the anesthesia workload/workforce ratio on quality and safety outcomes of obstetric anesthesia care.MethodsObservers prospectively collected data from labor units over 72 h (Wednesday, Thursday and Friday). Independent variables were workload (WL) and workforce (WF). WL was assessed by the Obstetric Anesthesia Activity Index (OAAI), which is the estimated time in a 24-h period spent on epidurals and all cesarean deliveries. Workforce (WF) was assessed by the number of anesthesiologists dedicated to the labor ward per week. Dependent variables were the time until anesthesiologist arrival for epidural (quality measure) and the occurrence of general anesthesia for urgent Cesarean section, CS, (safety measure). This census included vaginal deliveries and unscheduled (but not elective) CS.ResultsData on 575 deliveries are from 12 maternity units only, primarily because a major hospital chain chose not to participate; eight other hospitals lacked institutional review board approval. The epidural response rate was 94.4%; 321 of 340 parturients who requested epidural analgesia (EA) received it. Of the 19 women who requested EA but gave birth without it, 14 (77%) were due to late arrival of the anesthesiologist. Median waiting times for anesthesiologist arrival ranged from 5 to 28 min. The OAAI varied from 4.6 to 25.1 and WF ranged from 0 to 2 per shift. Request rates for EA in hospitals serving predominantly orthodox Jewish communities and in peripheral hospitals were similar to those of the entire sample. More than a fifth (13/62; 21%) of the unscheduled CS received general anesthesia, and of these almost a quarter (3/13; 23%) were attributed to delayed anesthesiologist arrival.ConclusionsInadequate WF allocations may impair quality and safety outcomes in obstetric anesthesia services. OAAI is a better predictor of WL than delivery numbers alone, especially concerning WF shortage. To assess the quality and safety of anesthetic services to labor units nationally, observational data on workforce, workload, and clinical outcomes should be collected prospectively in all labor units in Israel.

Does Programmed Intermittent Epidural Bolus Improve Childbirth Conditions of Nulliparous Women Compared With Patient-controlled Epidural Analgesia? A Multicentre, Randomized, Controlled, Triple-blind Study

(Eur J Anaesthesiol. 2019;36:755–762) Currently about 80% of deliveries in France involve an epidural for labor analgesia. Epidural rates and programs have changed over time, but various authors have found that a programmed intermittent epidural bolus (PIEB) plus patient-controlled epidural analgesia (PCEA) demand dosing strategy for maintenance of labor analgesia decreased the rate of instrumental vaginal delivery, lessened anesthetic drug consumption and increased maternal satisfaction scores compared with a continuous background infusion+PCEA. This study aimed to investigate whether the use of a modern PIEB pump improved the mechanics of the second stage of labor compared with a conventional epidural analgesia technique.

Maternal and neonatal outcome of births planned in alongside midwifery units: a cohort study from a tertiary center in Germany

BackgroundFor healthy women entering birth after uneventful pregnancy, midwife-led models of care have the potential to reduce interventions and increase the vaginal birth rate. In Germany, 98.4% of women are giving birth in consultant-led obstetric units. Alongside midwifery units (AMU) have been established in 2003. We compared the outcome of women registered for planned birth in the AMU at our hospital with a matched group of low-risk women who gave birth in standard obstetric care during the same period of time.MethodsWe used a retrospective cohort study design. The study group consisted of all women admitted to labor ward who had registered for birth in AMU from 2010 to 2017. For the control group, low-risk women were selected; additionally, matching was performed for parity. Mode of birth was chosen as primary outcome parameter for the mother. For the neonate, a composite primary outcome (5-min Apgar < 7 or umbilical cord arterial pH < 7.10 or transfer to specialist neonatal care) was defined. Secondary outcomes included epidural anesthesia, duration of the second stage of labor, episiotomy, obstetric injury, and postpartum hemorrhage. Non-inferiority was assessed, and multiple logistic regression analysis was performed.ResultsSix hundred twelve women were admitted for labor in AMU, the control group consisted of 612 women giving birth in standard obstetric care. Women in the study group were on average older and had a higher body mass index (BMI); birthweight was on average 95 g higher. Non-inferiority could be established for the primary outcome parameters. Epidural anesthesia and episiotomy rates were lower, and the mean duration of the second stage of labor was shorter in the study group; second-degree perineal tears were less common, higher-order obstetric lacerations occurred more frequently.Overall, 50.3% of women were transferred to standard obstetric care. Regression analysis revealed effects of parity, age and birthweight on the chance of transfer.ConclusionCompared to births in our consultant-led obstetric unit, the outcome of births planned in the AMU was not inferior, and intervention rates were lower. Our results support the integration of AMU as a complementary model of care for low-risk women.

A double-blind randomised placebo-controlled trial of melatonin as an adjuvant agent in induction of labour (MILO): a study protocol

Complementary therapy and alternative medicine: effects on induction of labour and pregnancy outcome in low risk post-dates women

BackgroundComplementary therapy and Alternative medicine (CAM) is used worldwide for many ailments and is a popular option amongst pregnant women for general wellbeing and managing symptoms. Many studies investigating the use of CAM in the antenatal and intrapartum period have been conducted however there is a lack of evidence regarding its effects on induction of labour and delivery. We established a post-dates clinic comprising of an antenatal check and CAM for low risk pregnant women to determine the impact of CAM on these outcomes. MethodsThis was a cohort study with convenience sampling. A total of 1044 women were included. 397 received a combination of three CAM techniques (acupressure, reflexology and aromatherapy) and 647 women received standard clinical practice. The primary outcome was rate of induction of labour and secondary outcomes such as rates for epidural, length of labour, oxytocin use for induction or augmentation of labour, mode of delivery, blood loss during delivery, postpartum haemorrhage, significant perineal trauma, shoulder dystocia and admission of the baby to a special care unit were analysed. FindingsCAM did not have an effect on rates of induction of labour in nulliparous or multiparous women attending the post-dates clinic. However, we noted that nulliparous women who received CAM had shorter labours (mean 8.4 vs 10 h, p = 0.0002), less oxytocin augmentation (23% vs 35%, p = 0.0002), lower epidural rates (41% vs 50.5%, p = 0.02) and reduced blood loss regardless of mode of delivery (mean reduction 82ml, p = 0.03; 95%CI = -159 to -5). There were no significant differences in secondary outcomes when CAM was used in multiparous women apart from a 5.3 times increased risk of significant perineal trauma (6% vs 2%, p = 0.004) and those who had their labours induced after CAM had a higher risk of requiring an emergency caesarean section (5% vs 1%, p = 0.012). There was no difference on shoulder dystocia and neonatal admissions rates with CAM. ConclusionThere is no reduction in induction of labour rates with the use of CAM. The other effects of CAM on labour and delivery outcomes are varied and potentially only beneficial in a selected group of women. Further research must be carried out before making any clear recommendations on its use.
