Global issues in obstetric anaesthesia: perspectives from South Africa, Japan, China, Latin America and North America.

South Africa is classified as a low- and middle-income country, with a complex mixture of resource-rich and resource-limited settings. In the major referral hospitals, the necessary skill level exists for the management of complex challenges. However, this contrasts with the frequently-inadequate skill levels of anaesthesia practitioners in resource-limited environments. In Japan, obstetricians administer anaesthesia for 40% of caesarean deliveries and 80% of labour analgesia. Centralisation of delivery facilities is now occurring and it is expected that obstetric anaesthesiologists will be available 24 h a day in centralised facilities in the future. In China, improvements in women's reproductive, maternal, neonatal, child, and adolescent health are critical government policies. Obstetric anaesthesia, especially labour analgesia, has received unprecedented attention. Chinese obstetric anaesthesiologists are passionate about clinical research, focusing on efficacy, safety, and topical issues. The Latin-American region has different landscapes, people, languages, and cultures, and is one of the world's regions with the most inequality. There are large gaps in research, knowledge, and health services, and the World Federation of Societies of Anaesthesiologists is committed to working with governmental and non-governmental organisations to improve patient care and access to safe anaesthesia. Anaesthesia workforce challenges, exacerbated by coronavirus disease 2019, beset North American healthcare. Pre-existing struggles by governments and decision-makers to improve health care access remain, partly due to unfamiliarity with the role of the anaesthesiologist. In addition to weaknesses in work environments and dated standards of work culture, the work-life balance demanded by new generations of anaesthesiologists must be acknowledged.

Equity in provision and access to obstetric anaesthesia care in Nigeria.

Nigeria has a high maternal mortality rate, yet there is wide variation in the proportion of births by caesarean section between zones, states, and cities within Nigeria. This review examines the pattern of the COVID-19 pandemic and the impact of mitigation measures on women's health in Nigeria. The combined impact of COVID-19 and conflicts on maternal healthcare and access to obstetric care, as well as the availability of obstetric anaesthesia in Nigeria, are discussed. There is a vicious cycle, intensified by unwanted pregnancy, abortion, and preventable maternal death.

Hemodynamic changes associated with neuraxial anesthesia in pregnant women with covid 19 disease: a retrospective case-control study.

BACKGROUND: Neuraxial blocks is the recommended mode of analgesia and anesthesia in parturients with Coronavirus 19 (COVID-19). There is limited data on the hemodynamic responses to neuraxial blocks in COVID-19 patients. We aim to compare the hemodynamic responses to neuraxial blocks in COVID-19 positive and propensity-matched COVID-19 negative parturients. METHODS: We conducted retrospective, cross-sectional case-control study of hemodynamic changes associated with neuraxial blocks in COVID-19 positive parturients in a Tertiary care academic medical center. Fifty-one COVID-19 positive women confirmed by nasopharyngeal reverse transcription-polymerase chain reaction (RT-PCR), were compared with propensity-matched COVID negative controls (n = 51). Hemodynamic changes after neuraxial block were recorded by electronic medical recording system and analyzed using paired and unpaired T- test and Wilcoxon-Mann-Whitney Rank Sum tests. The primary outcome was ≥ 20% change in MAP and HR after neuraxial block placement. RESULTS: In the epidural group, 7% COVID-19 positive parturients had > 20% decrease in mean arterial pressure (MAP) from baseline compared to 15% COVID-19 negative parturients (P = 0.66). In the spinal group, 83% of COVID-19 positive parturients had a decrease in MAP more than 20% from baseline compared to 71% in control (P = 0.49). MAP drop of more than 40% occurred in 29% COVID positive parturients in the spinal group versus 17% in COVID-19 negative parturients (P = 0.5465). In COVID-19 positive spinal group, 54% required vasopressors whereas 38% in COVID-19 negative spinal group required vasopressors (P = 0.387). We found a significant correlation between body mass index (BMI) > 30 and hypotension in COVID ( +) parturient with odds ratio (8.63; 95% CI-1.93 - 37.21) (P = 0.007). CONCLUSION: Incidence and severity of hypotension after neuraxial blocks were similar between COVID-19 positive and COVID-19 negative parturients. BMI > 30 was a significant risk factor for hypotension as described in preexisting literature, this correlation was seen in COVID-19 positive parturients. The likely reason for parturients with BMI > 30 in COVID negative patients not showing similar correlation, is that the sample size was small.

Opinion paper: gynecological surgery in local anesthesia?

PURPUSE: The paracervical block (PCB) is a local anesthesia procedure that can be used to perform gynecological surgeries without the need for further anesthesia. With the PCB, surgeries can be moved from the central operating room to outpatient operating rooms, where they can be performed without the presence of an anesthesia team. METHODS: In this paper, the indications, implementation and limitations of the procedure are discussed. CONCLUSION: Especially in times of scarce staff and OR resources during the Corona pandemic, OR capacity can be expanded in this way.

Anesthesia Considerations for Pregnant People With COVID-19 Infection.

The purpose of this review is to describe updates following initial recommendations on best anesthesia practices for obstetric patients with coronavirus disease 2019. The first surge in the United States prompted anesthesiologists to adapt workflows and reconsider obstetric anesthesia care, with emphasis on avoidance of general anesthesia, the benefit of early neuraxial labor analgesia, and prevention of emergent cesarean delivery whenever possible. While workflows have changed to allow sustained safety for obstetric patients and health care workers, it is notable that obstetric anesthesia protocols for labor and delivery have not significantly evolved since the first coronavirus disease 2019 wave.

[COVID-19 in obstetric anesthesia : Prospective surveillance of peripartum infections with SARS-CoV-2 and peripartum course of disease in affected women]. / COVID-19 in der geburtshilflichen Anästhesie : Prospektive Erfassung von SARS-CoV-2-Infektionen zum Zeitpunkt der Geburt sowie des peripartalen Verlaufs SARS-CoV-2-positiver Schwangerer.

BACKGROUND: In the current pandemic regarding the infection with the SARS-CoV-2-virus and COVID-19 as the disease, concerns about pregnant women, effects on childbirth and the health of the newborn remain high. Initially, due to the early manifestation of the disease in younger patients, high numbers of COVID-19 patients in women needing peripartum care were expected. OBJECTIVE: This article aims to provide a general overview over the beginning of the pandemic as well as the second wave of infections in Germany and Switzerland, regarding SARS-CoV­2 positive pregnant women hospitalized for childbirth. We therefore launched a registry to gain timely information over the dynamic situation during the SARS-CoV­2 pandemic in Germany. MATERIAL AND METHODS: As part of the COVID-19-related Obstetric Anesthesia Longitudinal Assessment (COALA) registry, centers reported weekly birth rates, numbers of suspected SARS-CoV­2 cases, as well as the numbers of confirmed cases between 16 March and 3 May 2020. Data acquisition was continued from 18 October 2020 till 28 February 2021. The data were analyzed regarding distribution of SARS-CoV­2 positive pregnant women hospitalized for childbirth between centers, calendar weeks and birth rates as well as maternal characteristics, course of disease and outcomes of SARS-CoV­2 positive pregnant women. RESULTS: A total of 9 German centers reported 2270 deliveries over 7 weeks during the first wave of infections including 3 SARS-CoV­2 positive cases and 9 suspected cases. During the second survey period, 6 centers from Germany and Switzerland reported 41 positive cases out of 4897 deliveries. One woman presented with a severe and ultimately fatal course of the disease, while another one needed prolonged ECMO treatment. Of the women 28 presented with asymptomatic infections and 6 neonates were admitted to a neonatal intensive care unit for further treatment. There was one case of neonatal SARS-CoV­2 infection. CONCLUSION: The number of pregnant women infected with SARS-CoV­2 was at a very low level at the time of delivery, with only sporadic suspected or confirmed cases. Due to the lack of comprehensive testing in the first survey period, however, a certain number of asymptomatic cases are to be assumed. Of the cases 68% presented as asymptomatic or as mild courses of disease but the data showed that even in young healthy patients without the presence of typical risk factors, serious progression can occur. These outcomes should raise awareness for anesthesiologists, obstetricians, pediatricians and intensive care physicians to identify severe cases of COVID-19 in pregnant women during childbirth and to take the necessary precautions to ensure the best treatment of mother and neonate. The prospective acquisition of data allowed a timely assessment of the highly dynamic situation and gain knowledge regarding this vulnerable group of patients.

The Society for Obstetric Anesthesia and Perinatology Coronavirus Disease 2019 Registry: An Analysis of Outcomes Among Pregnant Women Delivering During the Initial Severe Acute Respiratory Syndrome Coronavirus-2 Outbreak in the United States.

BACKGROUND: Early reports associating severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection with adverse pregnancy outcomes were biased by including only women with severe disease without controls. The Society for Obstetric Anesthesia and Perinatology (SOAP) coronavirus disease 2019 (COVID-19) registry was created to compare peripartum outcomes and anesthetic utilization in women with and without SARS-CoV-2 infection delivering at institutions with widespread testing. METHODS: Deliveries from 14 US medical centers, from March 19 to May 31, 2020, were included. Peripartum infection was defined as a positive SARS-CoV-2 polymerase chain reaction test within 14 days of delivery. Consecutive SARS-CoV-2-infected patients with randomly selected control patients were sampled (1:2 ratio) with controls delivering during the same day without a positive test. Outcomes were obstetric (eg, delivery mode, hypertensive disorders of pregnancy, and delivery <37 weeks), an adverse neonatal outcome composite measure (primary), and anesthetic utilization (eg, neuraxial labor analgesia and anesthesia). Outcomes were analyzed using generalized estimating equations to account for clustering within centers. Sensitivity analyses compared symptomatic and asymptomatic patients to controls. RESULTS: One thousand four hundred fifty four peripartum women were included: 490 with SARS-CoV-2 infection (176 [35.9%] symptomatic) and 964 were controls. SARS-CoV-2 patients were slightly younger, more likely nonnulliparous, nonwhite, and Hispanic than controls. They were more likely to have diabetes, obesity, or cardiac disease and less likely to have autoimmune disease. After adjustment for confounders, individuals experiencing SARS-CoV-2 infection exhibited an increased risk for delivery <37 weeks of gestation compared to controls, 73 (14.8%) vs 98 (10.2%) (adjusted odds ratio [aOR], 1.47; 95% confidence interval [CI], 1.03-2.09). Effect estimates for other obstetric outcomes and the neonatal composite outcome measure were not meaningfully different between SARS-CoV-2 patients versus controls. In sensitivity analyses, compared to controls, symptomatic SARS-CoV-2 patients exhibited increases in cesarean delivery (aOR, 1.57; 95% CI, 1.09-2.27), postpartum length of stay (aOR, 1.89; 95% CI, 1.18-2.60), and delivery <37 weeks of gestation (aOR, 2.08; 95% CI, 1.29-3.36). These adverse outcomes were not found in asymptomatic women versus controls. SARS-CoV-2 patients (asymptomatic and symptomatic) were less likely to receive neuraxial labor analgesia (aOR, 0.52; 95% CI, 0.35-0.75) and more likely to receive general anesthesia for cesarean delivery (aOR, 3.69; 95% CI, 1.40-9.74) due to maternal respiratory failure. CONCLUSIONS: In this large, multicenter US cohort study of women with and without peripartum SARS-CoV-2 infection, differences in obstetric and neonatal outcomes seem to be mostly driven by symptomatic patients. Lower utilization of neuraxial analgesia in laboring patients with asymptomatic or symptomatic infection compared to patients without infection requires further investigation.

Our anesthesia experiences in COVID-19 positive patients delivering by cesarean section: A retrospective single-center cohort study.

AIM: Pregnancy increases susceptibility to respiratory complications of viral diseases. This study aims to evaluate our anesthesia practices in pregnant women with COVID-19 undergoing cesarean section. METHODS: A total of 61 patients who underwent cesarean section and had positive Polymerase chain reaction (PCR) testing for COVID-19 with nasopharyngeal swabs were included in the study. Patient demographics and information about anesthesia were analyzed retrospectively from the patient medical files. RESULTS: A total of 61 parturients undergoing cesarean section that had positive SARS-CoV-2 PCR tests were assessed. General anesthesia was applied to only three patients (4.9%), while spinal anesthesia was administered to the remaining 58 patients (95.1%). The incidence of hypotension was 25.9% in the spinal anesthesia group. Forty-one (67.2%) parturients were asymptomatic. While the rate of pneumonia in symptomatic patients was 45% (9/20), the pneumonia incidence among all SARS-CoV-2 PCR (+) parturients was 14% (9/61). Three (4.9%) COVID-19 patients required intensive care in the perioperative period. The overall mortality rate was 1.6% (1/61) among parturients with COVID-19 undergoing cesarean section, while it was 11.1% (1/9) in patients with pneumonia. CONCLUSION: It was observed that COVID-19 is associated with mortality in pregnant women undergoing cesarean section. Spinal anesthesia was safely and effectively administered in COVID-19 parturients, especially in patients with pneumonia.

Adaptation of an Obstetric Anesthesia Service for the Severe Acute Respiratory Syndrome Coronavirus-2 Pandemic: Description of Checklists, Workflows, and Development Tools.

BACKGROUND: Care of the pregnant patient during the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic presents many challenges, including creating parallel workflows for infected and noninfected patients, minimizing waste of materials, and ensuring that clinicians can seamlessly transition between types of anesthesia. The exponential community spread of disease limited the time for development and training. METHODS: The goals of our workflow and process development were to maximize safety for staff and patients, minimize the risk of contamination, and reduce the waste of unused supplies and materials. We used a cyclical improvement system and the plus/delta debriefing method to rapidly develop workflows consisting of sequential checklists and procedure-specific packs. RESULTS: We designed independent workflows for labor analgesia, neuraxial anesthesia for cesarean delivery, conversion of labor analgesia to cesarean anesthesia, and general anesthesia. In addition, we created procedure-specific material packs to optimize supplies and prevent wastage. Finally, we generated sequential checklists to allow staff to perform standard operating procedures without extensive training. CONCLUSIONS: Collectively, these workflows and tools allowed our staff to urgently care for patients in high-risk situations without prior experience. Over time, we refined the workflows using a cyclical improvement system. We present our checklists and workflows as well as the system we used for their development, so that others may use them to their benefit.

Pandemics and maternal health: the indirect effects of COVID-19.

Infectious diseases can directly affect women and men differently. During the COVID-19 pandemic, higher case fatality rates have been observed in men in most countries. There is growing evidence, however, that while organisational changes to healthcare delivery have occurred to protect those vulnerable to the virus (staff and patients), these may lead to indirect, potentially harmful consequences, particularly to vulnerable groups including pregnant women. These encompass reduced access to antenatal and postnatal care, with a lack of in-person clinics impacting the ability to screen for physical, psychological and social issues such as elevated blood pressure, mental health issues and sex-based violence. Indirect consequences also encompass a lack of equity when considering the inclusion of pregnant women in COVID-19 research and their absence from vaccine trials, leading to a lack of safety data for breastfeeding and pregnant women. The risk-benefit analysis of these changes to healthcare delivery remains to be fully evaluated, but the battle against COVID-19 cannot come at the expense of losing existing quality standards in other areas of healthcare, especially for maternal health.
