Gender and graduating results in the Anesthesiology and Intensive Care Abomey-Calavi (Cotonou, Benin) program

Background: For unknown reasons female participation in anesthesiology is very low in Sub-Saharan Africa (SSA), especially in West Africa, and few women reach top academic or clinical positions. Objective: Women reduced professional perspectives. Design: Male and female residents’ performances were compared when they presented for their first try the graduating exams of the specialty. Settings: The Cotonou anesthesiology and intensive care training center, the second largest in French-speaking SSA, where 146 anesthesiologists from 14 African countries graduated since its creation in 1996. Method: All results at their final exams (consisting in 3 written questions and 2 clinical evaluations) were retrieved for the 125 men and 21 women who graduated. Scores obtained by women and males were compared using Student’s t tests. Their total of points was used to divide graduates into deciles. The proportion of women was counted in each decile. Results: Women performed better at both anesthesia and intensive care clinical evaluations taken separately and together (total 68.2% vs. 64.2% p=0.004) and were even with men for the three written exams (anesthesia, intensive care and basic sciences - total 66.2 % vs. 66.1% p=0.99). When clinical and written scores are added in each sector, women scored better than males for anesthesiology (69.2% vs. 65.2% p=0.01) and were even for intensive care (65.0% vs. 64.1% p=0.51). Globally women and men results were similar (67% vs. 65%, p=0.1) The proportion of women in each decile increased from the lowest to the best deciles, but the absolute low number of women gives this trend borderline significance (slope +1,56 % women per decile, p=0.046)**. Conclusion: Women performance at end-specialty exams is unlikely to explain their subsequent underrepresentation at the academic level in anesthesia and intensive care in SSA**.

[Prognosis value of two gravity scores in patients in the intensive care unit at University Hospital of Parakou in Northern Benin]

OBJECTIVE

To determine the prognosis value of two generalgraveness' scores in patients admitted to intensive care at University Hospital of Parakou in Northern Benin.

PATIENTS AND METHODS

Descriptive and analytical observational study data were collected from March 1^st to June 30^th, 2017. The SAPS II and APACHE II were calculated during first 24 hours of hospitalization to assess the clinical graveness and predict patient's mortality.

RESULTS

We enrolled 185 patients representing 89.37% of admissions, majority were men (63.78%). Mean age was 38.89 ± 17.92 years (16 to 99), mean of hospitalization duration were 4.36 ± 2.2 days. Neurological failure was the most common disorder observed (58.37%). Mean SAPS II and APACHE II was 29.54 ± 19.04 and 14.24 ± 10.49 respectively. Mean predicted mortality of SAPS II and APACHE II was 19.12 ± 5.05 and 25.69 ± 5.00 respectively. The mortality rate was 25.95% and increased with severity scores. The sensibility of APACHE II and SAPS II score was72.90% and 66.70% respectively. SAPS II score was found to be most specific (85.40%) than APACHE II (80.03%).

CONCLUSION

Those severity patient scores accurately predicted the prognosis of patients in intensive unit and should be integrated in our practice.

[North-South cooperation on transfusion and hematology teaching: A Benin experience]

Hematologic diseases are a significant part of health disorders in Benin. As an example, anemia is the second cause of hospitalization, measuring up to 7.9% all over the country (National Plan of Sanitary Development, 2009-2018). By contrast, there is only one active hematologist in the country. Thanks to two partnerships, on one hand between the health sciences faculty in Cotonou (Benin) and the medicine one in Tours (France), and on the other hand between the Beninese Blood Transfusion National Agency and the French Blood Establishment, a first blood transfusion and hematology formation was held in Cotonou on December 2014. Among other benefits, was created an hematology-transfusion network in order to facilitate relations between Beninese hospital doctors, with the support of the two French partner institutions. The article describes this progress.

[Preoperative psychological experience and beliefs in adult patients scheduled for surgery at the University Hospital of Parakou in Benin]

OBJECTIVE

To study the preoperative psychological experience and beliefs in adult patients scheduled for surgery at the University Hospital of Parakou.

PATIENTS AND METHODS

A descriptive and analytical study with prospective data collection conducted over three months (June 1st to August 30, 2012) and involved 75 patients.

RESULTS

Of the 108 patients scheduled for surgery, 75 patients (69.44%) had been chosen. The average age was 44.11±16.24 years with a male predominance (56%). Fifty-five patients (73.3%) were anxious and 32 patients (46.7%) were afraid of dying. Forty-five patients (60%) had not received any information about the procedure they should undergo and 60 patients (80%) were not informed of the possible complications of surgery. Fifty-eight patients (77.3%) were aware of the anesthetic technique and 5.2% of patients were aware of the possible complications of anesthesia. In 56 patients (74.7%), the disease was of natural origin, in 18.6% of cases there was an enchantment and 5 patients (6.7%) the disease is due to a deity. In the context of spiritual care, 15 patients (20%) had consulted a marabout, 11 patients (14.7%) a healer and 10 patients (13.3) a fetish.

CONCLUSION

The preoperative period induces a significant burden of anxiety among patients and their families. In Benin, the announcement of surgery is an opportunity for confrontation of the patient to an obsession with death which he manages to escape despite the countless sacrifices of traditional conjuring.

Anesthesiologists' demography in French-speaking Sub-Saharan Africa: the impact of fifteen years of Belgo-Beninese cooperation

Belgium has been collaborating with the French-speaking University of Abomey-Calavi in Cotonou (Republic of Benin) for 15 years to train anesthesiologists for Sub-Saharan French-speaking African countries. At the end of the nineties, Sub-Saharan Africa was the only part of the world with a decreasing number of anesthesiologists. Thanks to various financial supports coming mainly from Belgian governmental cooperation funds, the program has been successful in reversing the demographic trend and even started a multiplying effect through the creation of schools for nurse-anesthetists, and through the creation of new training centers for physician anesthesiologists. Sixty-nine anesthesiologists from 13 countries graduated from Cotonou, 59 (85.5%) of whom actually choose to work in Africa. At least 40 of them teach anesthesia, playing a key role in the creation of new schools and training centers.

[Early resumption of food intake after cesarean section in black African women: liquid versus solid food]

OBJECTIVE

The purpose of this study was to compare the effects of early resumption of solid versus liquid food intake after emergency cesarean section in black African women, in terms of gastrointestinal complications and maternal satisfaction.

PATIENTS AND METHOD

A total of 120 patients were randomly distributed into two groups of 60 each. In group L, liquid food intake in the form of sweetened citronella drink was allowed at will starting 6 six hours after the procedure but no solid food was allowed for 24 hours. In group S, normal solid food intake was resumed six hours after the procedure. The two study groups were not significantly different with regard to age, medical history, ASA class, obstetrical status, indications for cesarean section, anesthetic protocol, mean procedural duration, and postoperative analgesia. Study variables included tolerance of food intake, gastro-intestinal complications, time necessary to resume full activity and patient satisfaction.

RESULTS

Overall, 6% of patients reported complications involving nausea, vomiting and bloating. There was no statistical difference between the two groups. Normal intestinal transit resumed earlier in group S but the difference was not significant. Auscultation of the abdomen at 16 hours after the procedure demonstrated presence of peristalsis in 59 patients in group S and 51 in group L (p = 0.008). The maternal satisfaction rate was 92% in group S and 43% in group L (p <0.01). All dissatisfied patients said that they would opt for solid food in case of future cesarean.

CONCLUSION

Early solid food intake after cesarean in black African women is as well tolerated as early liquid feeding. Resumption of solid food intake allows earlier rehabilitation and improves patient satisfaction.

[Perioperative morbidity and mortality in a developing country: experience of Lomé teaching hospital]

OBJECTIVE

New evaluation of early perioperative morbidity and mortality four years after the first study in 2002, at Lomé teaching hospital (Togo).

PATIENTS AND METHODS

It was a prospective and descriptive survey during the first semester of 2006. After approval of hospital ethic committee, medical and demographic data, complications and early perioperative deaths have been analyzed.

RESULTS

One thousand nine hundred and two anaesthesia was delivered: 58% were women, the average age was 26 years, 94% of patient ASA<3, general anaesthesia (GA) 53% versus regional anaesthesia (LRA): 47%. Spinal anaesthesia (SA) represented 42% of anaesthetic procedures, and emergencies, 56%. 5.49% of complications including 16.16% of deaths were recorded. Death occurred in 69% after GA, and in 60% in the operating room. Seventy percent of patients had cardiovascular complications (five deaths), 30% respiratory failure (six deaths), 11% kidney failures (two deaths). Three deaths were linked to surgery (inadequate management of perioperative haemorrhage). Early perioperative mortality rate was 0.89%. Four cases occurred in the operating room and 12 in intensive care. Deaths were observed often in gynecology and obstetrics (9/16), especially in emergency situations (12/16) and in 75% of cases, patients were ASA>2. Deaths occurred in 13 cases after GA and in three cases after SA.

CONCLUSION

This mortality rate was smaller than in 2002. This may be explained by a better prenanaesthetic risk evaluation performed by anaesthetists, the creation of postoperative recovery room, the promotion of regional anaesthesia and the availability of succinylcholine in obstetrics. Significant improvement is still necessary and only be obtained by a national health policy.

[Use of ilio-inguinal iliohypogastric nerve block for herniorraphy: a prospective study in a 35-case series at the Lome University Hospital Center in Togo]

The purpose of this prospective-descriptive study was to evaluate the quality of anaesthesia and analgesic effect achieved by ilio-inguinal iliohypogastric nerve block (IINB) in patients undergoing herniorraphy. Study was carried out over a 6-month period in the Anaesthesia Intensive Care Department of the Lomé University Hospital Centre in Togo. All patients indicated for unilateral herniorraphy were enrolled. A total of 35 patients underwent herniorraphy with IINB. Mean patient age was 32 years. Farmers accounted for 57% of the population. Men accounted for 86.7%. The anaesthesia classification was ASA I or II in 88.6% of cases. Complete sensory block was obtained within 15 minutes after induction in 71.43% of cases. Additional sedation using ketamine and/or fentanyl was used in 51.43% of cases. Conversion from IINB to general anaesthesia was necessary in three cases including 2 due to extension of the surgical incision and one for the surgeon's convenience. The mean duration of the procedure was 70 minutes. Intraoperative complications included nausea in one case, dizziness in 2 cases, and bitterness in mouth in 3 cases. Postoperatively, extension to the femoral nerve was observed in 2 cases. Five patients presented a visual analogue pain scale (VAS) > or = 4 within 18 hours after the procedure. This study shows that IINB is a useful alternative to general anaesthesia for herniorraphy. Specific training is necessary to allow more widespread use.

[Knowledge and acceptance of obstetric peridural analgesia: survey of pregnant women in Togo]

The purpose of this study was to evaluate knowledge and acceptance of obstetric peridural analgesia among pregnant women in Togo. A prospective, descriptive survey was carried out over a period of one month. A standardized survey form was used to collect data. A total of 303 pregnant women with a mean age of 27 +/- 6 years were interviewed. A proportion of primiparous and multiparous was the same, i.e., 50%. Among multiparous women, 83.5% described labor pain during previous deliveries as severe. Twelve percent of the pregnant women interviewed claimed knowledge of techniques to control labor pain. Three pregnant women reported a detailed understanding of peridural analgesia obtained from the Internet. A total of 253 women (83.5%) replied affirmatively when asked if they would opt for peridural analgesia if it was offered free of charge for delivery at the end of the current pregnancy. Acceptance was motivated by better delivery conditions for the newborn (112 women) and comfort achieved by pain relief (130 women). Refusal was motivated by a religious belief that painful delivery was in the natural order (31 women). Among the six Moslem women that refused painless delivery, two from the Djerma ethnic group stated that pain was the best expression of their femininity. The acceptance rate fell from 83.5% to 70% if peridural analgesia was offered at extra charge. Most pregnant women in Togo expressed interest in trying peridural analgesia. It is compulsory in medical indications.

Anesthesia in French-speaking Sub-Saharan Africa: an overview

The situation of Anesthesiology in Sub-Saharan Africa is unique in that nowhere else in the world has the absolute numbers of anesthesiologists decreased during the nineties. Most anesthesia services to the populations of these 17 poor countries are provided by nurse-anesthetists, either certified or trained on the job. Their mean age often exceeds 40, which leads to expect an acute shortage within fifteen years. Experienced anesthesiologists are now so few that, in most countries, the critical mass of knowledgeable specialists no longer exists to train new anesthesia professionals. This summary of local surveys provides a brief overview of current workforce, institutions, drugs and material constituting the daily environment of our colleagues. Challenges are outlined, with special emphasis on brain drain. Solutions are proposed, underlining the promising role of a few anesthesia schools, the need for young anesthesiologists to enter teaching, and the expectations they are supposed to meet.

[Practice of the thromboembolic disease prophylaxis: a survey among surgeons and anaesthetists in Togo]

OBJECTIVE

The aim of this study was to analyse the current practice of postoperative venous thromboembolism (VTE) prophylaxis among anaesthetists, nurse anaesthetist and general surgeons in Togo.

METHOD

A total of 160 questionnaires were distributed to anaesthetists and surgeons with varying subspeciality interests.

RESULTS

One hundred and three (64%) (3 anaesthetists, 51 nurse anaesthetists and 49 surgeons) returned the questionnaire. Of these, 16% thought that VTE was as common in Togo as in the western countries. Selective VTE prophylaxis was used by 78% of the prescriptors. In order of frequency, indications for selective VTE prophylaxis were obesity, increased risk of VTE related to surgery and past medical history of VTE. Orthopaedic surgery, caesarean section and vascular surgery were most frequently considered as high-risk surgery for VTE event. When prophylaxis was indicated, low molecular weight heparin was prescribed by 87% of prescriptors. In most cases, VTE prophylaxis duration was less than a week. In 92% of institutions, there was no written protocol for VTE prophylaxis. VTE-related morbidity was reported by 34% of the prescriptors over the past year, and 30% of these cases were fatal; 60% of the prescriptors observed these complications one week after the surgery.

CONCLUSION

The practice of VTE prophylaxis in Togo is not sufficient. It is necessary to promote the training of practitioners, particularly of physicians.

Deaths associated with anaesthesia in Togo, West Africa

This study attempts to determine the anaesthetic death rate, the causes of deaths and the avoidable mortality rate (AMR) in consecutive cases. The number of anaesthetics given was 1464: 30 cases died within 24 h. The incidence of 24-h perioperative deaths per 100 anaesthetics was 2.57. In all, 50% of deaths were observed in obstetric surgery; 47% of deaths were associated with cardiovascular management, 30% with respiratory management; 93% of deaths were identified as avoidable. The AMR was 1.5% (anaesthetic AMR: 0.75%, administrative AMR: 0.68%, surgical AMR: 0.07%). Insufficient or no blood available is the only factor for administrative AMR.

[Maternal deaths and anesthetics in the Lomé (Togo) University Hospital]

AIM

To assess the results of anesthesia practices in a department particularly inadequately staffed with physicians specializing in anesthesiology.

SETTING AND METHODS

This six-month prospective study (from January through June 2002) took place in the anesthesiology/intensive care unit of the obstetrics and gynecology department of Lomé University Hospital Center. A case report file was completed for each patient, and all anesthetics administered in the obstetrical department (labor and delivery room) were recorded and considered. We examined the perinatal deaths among women who underwent surgery.

RESULTS

Anesthetics were administered to 318 women during cesarean delivery (306) and uterine scar repair (12). Nearly all patients (98%) were classified in categories 1 or 2 of the ASA physical status classification system (healthy or mild systemic disease). General anesthesia was induced in 95.9% of the women and spinal bloc used for 4.1%. Thiopental was used most often, and certain drugs, including succinylcholine and ephedrine, were not available as needed. Intraoperative monitoring was essentially nonexistent. Emergency situations accounted for 89.6% of these surgical procedures. Of the 16 cases requiring transfusions, an inadequate supply of blood products or the patient's inability to obtain blood was reported in 14 of the cases. Twelve deaths occurred, for a mortality rate among surgical patients of 3.8%. The principal causes of death were respiratory complications of anesthesia and of pregnancy-related toxemia and the unavailability of hypertonic solutions and blood products.

CONCLUSION

The results of this survey show that anesthetics play a role in maternal mortality in Togo. Good practice guidelines adapted to this setting must therefore be developed.

[Geoclimatology and severity of snake bite envenomations in Benin]

Envenomations following snakebite are common in Benin where they constitute, particularly in certain areas, a significant problem for the local populations and health workers. The present epidemiological study describes the snakebite envenomations which occurred in 18 medical centres of the country (6 departmental hospitals and 12 provincial hospitals). The studied variables were: prevalence, length of hospitalisation, major complications, quality of therapeutic management and development of the disease according to area. The study covered a period from April 2000 to March 2001. 486 cases of snakebite necessitating hospitalisation were notified including 413 (85%) in the two northern departments: Atacora and Borgou. Males were largely predominant (90%) and patients under 40 years were the most numerous (82%). The dry season seemed a period of higher risk (75% of the cases). The delay between the bite and admission to hospital, studied for 120 patients in the area of Atacora (North-West Benin), was relatively long: the average was 4 days, with extremes ranging from 10 hours to 21 days. This delay explained the severity of the complications diagnosed. They can be listed according to decreasing frequency: shock, coagulopathy, acute renal failure, respiratory distress. Less than 20% of the patients could benefit from antivenom. Management in emergency care units was impossible in most cases, none of the medical centres (except in Porto-Novo, the capital) having an intensive care unit with artificial ventilation available. Average mortality was 22%. Poisonous snakebites remain serious in Benin, mainly in the northern part of the Country. Access to health care and the quality of the management must be improved. This will require significant efforts from health workers, medical authorities as well as the local population. It is urgent to plan a national therapeutic consensus to reduce the high mortality due to snakebites.

[Epidemiological data on snake bite cases reported in Benin from 1994 to 2000]

Snake bites constitute a frequent occupational injury, mainly occuRring during agricultural activities in Benin as in the majority of tropical countries. The present study was performed within the scope of a periodic epidemiological analysis of occupational injuries over the past 15 years. It is a retrospective study based on the snake bites reported by the Ministry of Public Health from 1994 to 2000. The data collected through the medical centre registers showed that, with a total of 30,273 cases declared during these 7 years, snakebites represent less than 1% of the whole causes of admission. Although the prevalence was weak, the lethality was very high (15%). Envenomations involved more deaths than malaria and acute respiratory infections together. One third of cases occurred in adults and teenagers. Lethality in infants was not negligible. The two departments of northern Benin accounted for 314 of the envenomations. Lethality does not appear to be decreasing. The routine management of cases should be improved by appropriate training for health care workers and the introduction of a therapeutic strategy at every level of the medical system.

[Creation of emergency care services in developing countries: luxury or necessity?]

Organization of emergency care services prior to hospital admission has progressed at a satisfactory pace in developed countries. A performance model in this field is the French emergency service called service d'aide médicale d'urgence (SAMU). Socioeconomic conditions prevailing in developing countries have pushed authorities to give priority to preventive medicine. However numerous patients especially young people and women during childbirth die as a result of inadequate facilities for transportation from hospitals and dwellings in outlying areas to major medical centers where the best medical equipment and staff are available. As a result, it may be asked if emergency care services is really a luxury. The authors base their conclusion on analysis of the conditions and outcome of emergency patient care in three African countries in which it is essentially a requirement.

[Evolution of the demography of anesthesia practitioners in French speaking Sub-Saharan Africa]

OBJECTIVE

To assess the course of the demography of anaesthesia providers in French-speaking subsaharian countries.

TYPE OF STUDY

Retrospective survey.

PERSONS

Doctors trained in anaesthesia and nurse anaesthetists registered in West African medical societies.

METHODS

Countries, hospitals, anaesthesia manpower, seniority and place of training were analysed.

RESULTS

In the 13 French-speaking subsaharian countries including 97.5-M inhabitants, 122 doctors and 868 nurses were registered as anaesthetists in 1998. Mean ratios were one doctor trained in anaesthesia for 799,180 inhabitants and one nurse anaesthetist for 112,327 inhabitants. From 1980 to 1998, these figures increased by a factor 11 for doctors (+1100%) and by a factor two for nurses (+100%). Most doctors were working in the chief town, in both public and private health care institutions.

CONCLUSIONS

In all French-speaking subsaharian countries, a major shortage of doctors trained in anaesthesia is existing.

[Anesthesia practice by nurse anesthetists in French speaking Sub-Saharan Africa]

OBJECTIVE

To evaluate the practice of anaesthesia in French-speaking subsaharian countries.

TYPE OF STUDY

Prospective survey.

PERSONS

Two hundred seventeen nurse anaesthetists, from 11 different countries.

METHODS

Anonymous questionnaire.

RESULTS

One third of nurses were practising anaesthesia since less than five years and 1/3 since more than 10. Only 39 (18%) were working in the country side. Thirty seven (17%) had been trained outside subsaharian Africa (in Cuba 6%, France 5%, Morocco 5% and Germany 1% respectively). Two hundred thirteen (98%) were performing general anaesthesia and 169 (78%) regional anaesthesia. Hundred sixty eight (97%) used spinal anaesthesia, 57 (33%) epidural, 31 (18%) intravenous regional anaesthesia, 24 (14%) axillary block, 17 (10%) caudal block and 10 (6%) peripheral block respectively. For regional techniques, disposable devices were available in 50% of cases. For general anaesthesia, thiopental was administered by 193 (89%) and ketamine by 156 (72%) nurse anaesthetists respectively. In 50% of cases, these drugs were used alone. An ECG was available in 40%, a pulse oximeter in 14% and a capnographe in less than 2% of cases. A ventilator was present in 66% of the places, but used only in 30% of them because of the lack of maintenance and training.

CONCLUSIONS

In this study, 50% of nurse anaesthetists were working alone. However, this rate is probably under-estimated, as the questionnaire did not consider anaesthesia practice in the country side.
