Advances in pediatric anesthesia services over the past 10 years in French-speaking sub-Saharan Africa.

INTRODUCTION: To improve and maintain quality and safety in anesthesia, standards have been proposed regarding human resources, facilities and equipment, medications and intravenous fluids, monitoring, and the conduct of anesthesia. Compliance with these standards remains a challenge in French-speaking sub-Saharan Africa (SSA) and results in high morbidity and mortality particularly in children. This aim of this study was to assess the progress made in improving the pediatric anesthesia infrastructures, human resources, education, medications, and equipment in French-speaking SSA over the past 10 years (2013-2022). METHODS: This is a descriptive, multicenter, cross-sectional study with retrospective data collection, conducted from September 1 to November 5, 2023. Comparative data from 2012 to 2022 were collected through an online survey. Descriptive statistics were used to summarize data. RESULTS: Data were obtained from 12 countries out of 14. The number of hospitals providing pediatric surgery and anesthesia rose from 94 in 2012 to 142 in 2022 (+51%). The total number of physician anesthesiologists rose from 293 (0.1 physician anesthesiologists/100 000 inhabitants) in 2012 to 597 (0.2 physician anesthesiologists/100 000 inhabitants) in 2022 (+103.7%). Five (0.006 physician anesthesiologists/100 000 children) had completed a fellowship in pediatric anesthesia and intensive care in 2012, and 15 (0.01 physician anesthesiologists/100 000 children) in 2022 (+200%). Five physician anesthesiologists had an exclusive pediatric anesthesia practice in 2012, whereas they were 32 in 2022 (+540%). There is no specialized training in pediatric anesthesia and intensive care in any of these countries. Halothane was always available in 81.5% of the hospitals in 2012, and in 50.4% of the hospitals in 2022. Sevoflurane was always available in 5% of the hospitals in 2012, and in 36.2% in 2022. Morphine was always available in 32.2% in 2012, whereas it was available in 52.9% of them in 2022. Pediatric pulse oximeter sensors were available in 36% of the hospitals in 2012, and in 63.4% in 2022. Capnography was available in 5.3% of the hospitals in 2012, and in 48% in 2022. CONCLUSION: Progress have been made over the last 10 years in French-speaking SSA to improve infrastructures, human resources, education, medications, and equipment for pediatric anesthesia in French-speaking SSA. However, major efforts must be continued. Standards adapted to the local context should be formulated.

The Global Anesthesia Workforce Survey: Updates and Trends in the Anesthesia Workforce.

BACKGROUND: There is a large global deficit of anesthesia providers. In 2016, the World Federation of Societies of Anaesthesiologists (WFSA) conducted a survey to count the number of anesthesia providers worldwide. Much work has taken place since then to strengthen the anesthesia health workforce. This study updates the global count of anesthesia providers. METHODS: Between 2021 and 2023, an electronic survey was sent to national professional societies of physician anesthesia providers (PAPs), nurse anesthetists, and other nonphysician anesthesia providers (NPAPs). Data included number of providers and trainees, proportion of females, and limited intensive care unit (ICU) capacity data. Descriptive statistics were calculated by country, World Bank income group, and World Health Organization (WHO) region. Provider density is reported as the number of providers per 100,000 population. RESULTS: Responses were obtained for 172 of 193 United Nations (UN) member countries. The global provider density was 8.8 (PAP 6.6 NPAP 2.3). Seventy-six countries had a PAP density <5, whereas 66 countries had a total provider density <5. PAP density increased everywhere except for high- and low-income countries and the African region. CONCLUSIONS: The overall size of the global anesthesia workforce has increased over time, although some countries have experienced a decrease. Population growth and differences in which provider types that are counted can have an important impact on provider density. More work is needed to define appropriate metrics for measuring changes in density, to describe anesthesia cadres, and to improve workforce data collection processes. Effort to scale up anesthesia provider training must urgently continue.

Method of Anesthesia and Perioperative Risk Factors, Maternal Anesthesia Complications, and Neonatal Mortality Following Cesarean Delivery in Africa: A Substudy of a 7-Day Prospective Observational Cohort Study.

BACKGROUND: The African Surgical Outcomes Study (ASOS) found that maternal mortality following cesarean delivery in Africa is 50 times higher than in high-income countries, and associated with obstetric hemorrhage and anesthesia complications. Mothers who died were more likely to receive general anesthesia (GA). The associations between GA versus spinal anesthesia (SA) and preoperative risk factors, maternal anesthesia complications, and neonatal outcomes following cesarean delivery in Africa are unknown. METHODS: This is a secondary explanatory analysis of 3792 patients undergoing cesarean delivery in ASOS, a prospective observational cohort study, across 22 African countries. The primary aim was to estimate the association between preoperative risk factors and the outcome of the method of anesthesia delivered. Secondary aims were to estimate the association between the method of anesthesia and the outcomes (1) maternal intraoperative hypotension, (2) severe maternal anesthesia complications, and (3) neonatal mortality. Generalized linear mixed models adjusting for obstetric gravidity and gestation, American Society of Anesthesiologists (ASA) category, urgency of surgery, maternal comorbidities, fetal distress, and level of anesthesia provider were used. RESULTS: Of 3709 patients, SA was performed in 2968 (80%) and GA in 741 (20%). Preoperative factors independently associated with GA for cesarean delivery were gestational age (adjusted odds ratio [aOR], 1.093; 95% confidence interval [CI], 1.052-1.135), ASA categories III (aOR, 11.84; 95% CI, 2.93-46.31) and IV (aOR, 11.48; 95% CI, 2.93-44.93), eclampsia (aOR, 3.92; 95% CI, 2.18-7.06), placental abruption (aOR, 6.23; 95% CI, 3.36-11.54), and ruptured uterus (aOR, 3.61; 95% CI, 1.36-9.63). SA was administered to 48 of 94 (51.1%) patients with eclampsia, 12 of 28 (42.9%) with cardiac disease, 14 of 19 (73.7%) with preoperative sepsis, 48 of 76 (63.2%) with antepartum hemorrhage, 30 of 55 (54.5%) with placenta previa, 33 of 78 (42.3%) with placental abruption, and 12 of 29 (41.4%) with a ruptured uterus. The composite maternal outcome "all anesthesia complications" was more frequent in GA than SA (9/741 [1.2%] vs 3/2968 [0.1%], P < .001). The unadjusted neonatal mortality was higher with GA than SA (65/662 [9.8%] vs 73/2669 [2.7%], P < .001). The adjusted analyses demonstrated no association between method of anesthesia and (1) intraoperative maternal hypotension and (2) neonatal mortality. CONCLUSIONS: Analysis of patients undergoing anesthesia for cesarean delivery in Africa indicated patients more likely to receive GA. Anesthesia complications and neonatal mortality were more frequent following GA. SA was often administered to high-risk patients, including those with eclampsia or obstetric hemorrhage. Training in the principles of selection of method of anesthesia, and the skills of safe GA and neonatal resuscitation, is recommended.

[Subtotal sternal agenesis with ectopia cordis: surgical management and long-term outcome (a case in Benin)]. / Agénésie sternale subtotale avec ectopia cordis: gestion chirurgicale et résultat à long terme (à propos d´un cas au Bénin).

Sternal agenesis as well as ectopia cordis are extremely rare congenital malformations. We here report a single case treated in the Department of Paediatric Surgery in Benin. The study involved a 3-year-old girl with congenital sternal agenesis associated with ectopia cordis; firstly, she underwent controlled healing. Then thoracoplasty was performed with favourable outcome. Long-term results are good. Now, she is 13 years old, is attending school and has a satisfactory clinical condition. This is one of the few cases reported in the literature. Optimal therapeutic management has been keeping the patient alive in West Africa.

Anesthesia Provider Training and Practice Models: A Survey of Africa.

BACKGROUND: In Africa, most countries have fewer than 1 physician anesthesiologist (PA) per 100,000 population. Nonphysician anesthesia providers (NPAPs) play a large role in the workforce of many low- and middle-income countries (LMICs), but little information has been systematically collected to describe existing human resources for anesthesia care models. An understanding of existing PA and NPAP training pathways and roles is needed to inform anesthesia workforce planning, especially for critically underresourced countries. METHODS: Between 2016 and 2018, we conducted electronic, phone, and in-person surveys of anesthesia providers in Africa. The surveys focused on the presence of anesthesia training programs, training program characteristics, and clinical scope of practice after graduation. RESULTS: One hundred thirty-one respondents completed surveys representing data for 51 of 55 countries in Africa. Most countries had both PA and NPAP training programs (57%; mean, 1.6 pathways per country). Thirty distinct training pathways to become an anesthesia provider could be discriminated on the basis of entry qualification, duration, and qualification gained. Of these 30 distinct pathways, 22 (73%) were for NPAPs. Physician and NPAP program durations were a median of 48 and 24 months (ranges: 36-72, 9-48), respectively. Sixty percent of NPAP pathways required a nursing background for entry, and 60% conferred a technical (eg, diploma/license) qualification after training. Physicians and NPAPs were trained to perform most anesthesia tasks independently, though few had subspecialty training (such as regional or cardiac anesthesia). CONCLUSIONS: Despite profound anesthesia provider shortages throughout Africa, most countries have both NPAP and PA training programs. NPAP training pathways, in particular, show significant heterogeneity despite relatively similar scopes of clinical practice for NPAPs after graduation. Such heterogeneity may reflect the varied needs and resources for different settings, though may also suggest lack of consensus on how to train the anesthesia workforce. Lack of consistent terminology to describe the anesthesia workforce is a significant challenge that must be addressed to accelerate workforce research and planning efforts.

Maternal and neonatal outcomes after caesarean delivery in the African Surgical Outcomes Study: a 7-day prospective observational cohort study.

BACKGROUND: Maternal and neonatal mortality is high in Africa, but few large, prospective studies have been done to investigate the risk factors associated with these poor maternal and neonatal outcomes. METHODS: A 7-day, international, prospective, observational cohort study was done in patients having caesarean delivery in 183 hospitals across 22 countries in Africa. The inclusion criteria were all consecutive patients (aged ≥18 years) admitted to participating centres having elective and non-elective caesarean delivery during the 7-day study cohort period. To ensure a representative sample, each hospital had to provide data for 90% of the eligible patients during the recruitment week. The primary outcome was in-hospital maternal mortality and complications, which were assessed by local investigators. The study was registered on the South African National Health Research Database, number KZ_2015RP7_22, and on ClinicalTrials.gov, number NCT03044899. FINDINGS: Between February, 2016, and May, 2016, 3792 patients were recruited from hospitals across Africa. 3685 were included in the postoperative complications analysis (107 missing data) and 3684 were included in the maternal mortality analysis (108 missing data). These hospitals had a combined number of specialist surgeons, obstetricians, and anaesthetists totalling 0·7 per 100 000 population (IQR 0·2-2·0). Maternal mortality was 20 (0·5%) of 3684 patients (95% CI 0·3-0·8). Complications occurred in 633 (17·4%) of 3636 mothers (16·2-18·6), which were predominantly severe intraoperative and postoperative bleeding (136 [3·8%] of 3612 mothers). Maternal mortality was independently associated with a preoperative presentation of placenta praevia, placental abruption, ruptured uterus, antepartum haemorrhage (odds ratio 4·47 [95% CI 1·46-13·65]), and perioperative severe obstetric haemorrhage (5·87 [1·99-17·34]) or anaesthesia complications (11·47 (1·20-109·20]). Neonatal mortality was 153 (4·4%) of 3506 infants (95% CI 3·7-5·0). INTERPRETATION: Maternal mortality after caesarean delivery in Africa is 50 times higher than that of high-income countries and is driven by peripartum haemorrhage and anaesthesia complications. Neonatal mortality is double the global average. Early identification and appropriate management of mothers at risk of peripartum haemorrhage might improve maternal and neonatal outcomes in Africa.

Twenty Years of Collaboration Between Belgium and Benin in Training Anesthesiologists for Africa.

Belgium has been collaborating for 20 years with Abomey-Calavi University in Cotonou, Republic of Benin, to train anesthesiologists for Sub-Saharan, French-speaking African countries. With 123 graduates from 15 countries and 46 residents still in training, this program has succeeded in reversing the trend of a decreasing anesthesiology workforce in those countries, thus improving the quality of anesthesia and patient safety. Belgian government sources, as well as hospitals and anesthesia teams, provided most of the financial resources. Reasons for success, positive outcomes, and shortcomings are discussed, as well as future perspectives and threats. Failure to enroll enough female residents (15%) and brain drain (18% of alumni) are of concern. Alumni are capable of importing and adapting modern technology and practice. Graduates increase the impact of the Cotonou program by getting involved in teaching nonphysician anesthesia providers and by supporting new anesthesiology training programs being launched in several countries. Other African countries with training programs, by following this example, could accelerate anesthesiology progress by accepting foreign residents from the region. The role of anesthesiologists as anesthesia team leaders must be better defined, and residency training programs adapted accordingly. Continuing international support remains of critical importance, especially in the form of resident rotations to high-income countries. The development of structured anesthesiology programs should be encouraged by African governments as developing anesthesia is a prerequisite for surgical development in every discipline.

Rabies transmission risks during peripartum--Two cases and a review of the literature.

We report two cases of probable rabies in near-term/at-term pregnant women in sub-Saharan Africa and Asia. One baby was delivered by caesarean section and the other one vaginally. Both received post-exposure prophylaxis (PEP), including RIG and vaccine and both are alive and healthy, at 9 and 24 months, respectively. We found 14 other published cases of infants born from rabid mothers. One confirmed case of rabies transmission occurred. The other children born from rabid mothers, with or without caesarean section, did not acquire rabies, and were still healthy at the time of reporting, with or without post-exposure prophylaxis. Mother-to-child transmission of rabies is possible, but rare, because rabies virus is not present in blood and exposure of the baby's mucosa to maternal infectious fluids and tissue seems limited. A conservative approach should however, be adopted, and rabies PEP, including RIG, be administered as soon as possible to babies born from probably rabid mothers. Whether cesarean-section clearly provides prevention remains unclear. Rabies can be prevented in pregnant women by PEP administration. Rabies cell-culture vaccines are safe and effective and can be administered to pregnant and lactating women, as well as newborns. Efforts must focus on raising rabies awareness in the general population, as well as in healthcare workers.

Pediatric anesthesia in developing countries: experience in the two main university hospitals of Benin in West Africa.

AIMS: To describe the practice of pediatric anesthesia in the main University Hospitals in Benin. PATIENTS AND METHODS: We conduct a retrospective study involving 512 children at the 'Centre National Hospitalier et Universitaire' and the 'Hôpital de la Mère et de l'Enfant Lagune' in Cotonou. All children less than 15 years of age undergoing surgery from January to December 2007 were included. Patient demographics, anesthetic technique, perioperative monitoring and complications were analyzed. RESULTS: General anesthesia was used in 94% of children. Regional anesthesia was used in 1.7% of children at CNHU and 17% of children at Hôpital de la Mère et de l'Enfant Lagune. Inhalational induction was the commonest technique used. Halothane was the only inhalational agent available for induction. Seventy-two percent of children having general anesthesia were intubated. Muscle relaxation was used in 48% of cases, only with pancuronium. The available perioperative monitoring equipment was not used regularly. All children having general anesthesia breathed spontaneously with manual assistance. There were eight cardiac arrests recorded, giving an incidence of 156 cardiac arrests per 10,000 anesthetics. Hypoxia was the commonest cause of cardiac arrest. The mortality associated with cardiac arrest was very high (62%). There were three prognostic factors that predicted a poor outcome: age <1 year, emergency surgery and an ASA score of three or more. CONCLUSION: Pediatric anesthesia in the two University Hospitals is far from satisfactory. Morbidity and mortality are unacceptably high. Suggestions are made to improve the safety of children undergoing anesthesia.

Anesthesia for children in Sub-Saharan Africa--a description of settings, common presenting conditions, techniques and outcomes.

Anesthesia in developing countries deserves special attention. The most common technique is general anesthesia (with spontaneous or manually assisted ventilation). Nonmedical anesthetists with limited training and supervision and lacking the most common drugs and anesthetic equipment administer anesthesia, usually for emergency surgery. There are important safety issues, especially for pediatric anesthesia. Regarding pediatric surgery, the major workload is due to abdominal emergencies, mainly neonatal bowel obstruction or peritonitis due to typhoid perforation. The morbidity and mortality rate for these conditions is high.
