The impact of the Safer Anaesthesia from Education (SAFE) Obstetric Anaesthesia training course in Ethiopia: A mixed methods longitudinal cohort study.

SummaryReducing maternal mortality remains a global priority, particularly in low- and middle-income countries (LMICs). The Safer Anaesthesia from Education (SAFE) Obstetric Anaesthesia (OB) course is a three-day refresher course for trained anaesthesia providers addressing common causes of maternal mortality in LMICs. This aim of this study was to investigate the impact of SAFE training for a cohort of anaesthesia providers in Ethiopia.We conducted a mixed methods longitudinal cohort study incorporating a behavioural questionnaire, multiple-choice questionnaires (MCQs), structured observational skills tests and structured interviews for anaesthesia providers who attended one of four SAFE-OB courses conducted in two regions of Ethiopia from October 2017 to May 2018.Some 149 participants from 60 facilities attended training. Behavioural questionnaires were completed at baseline (n = 101, 69% response rate). Pre- and post-course MCQs (n = 121, n = 123 respectively) and pre- and post-course skills tests (n = 123, n = 105 respectively) were completed, with repeat MCQ and skills tests, and semi-structured interviews completed at follow-up (n = 88, n = 76, n = 49 respectively). The mean MCQ scores for all participants improved from 80.3% prior to training to 85.4% following training (P < 0.0001) and skills test scores improved from 56.5% to 83.2% (P < 0.0001). Improvements in MCQs and skills were maintained at follow-up 3-11 months post-training compared to baseline (P = 0.0006, < 0.0001 respectively). Participants reported improved confidence, teamwork and communication at follow-up.This study suggests that the SAFE-OB course can have a sustained impact on knowledge and skills and can improve the confidence of anaesthesia providers and communication within surgical teams.

Usability Testing of a Reusable Pulse Oximeter Probe Developed for Health-Care Workers Caring for Children < 5 Years Old in Low-Resource Settings.

Hypoxemia measured by pulse oximetry predicts child pneumonia mortality in low-resource settings (LRS). Existing pediatric oximeter probes are prohibitively expensive and/or difficult to use, limiting LRS implementation. Using a human-centered design, we developed a low-cost, reusable pediatric oximeter probe for LRS health-care workers (HCWs). Here, we report probe usability testing. Fifty-one HCWs from Malawi, Bangladesh, and the United Kingdom participated, and seven experts provided reference measurements. Health-care workers and experts measured the peripheral arterial oxyhemoglobin saturation (SpO2) independently in < 5 year olds. Health-care worker measurements were classed as successful if recorded in 5 minutes (or shorter) and physiologically appropriate for the child, using expert measurements as the reference. All expert measurements were considered successful if obtained in < 5 minutes. We analyzed the proportion of successful SpO2 measurements obtained in < 1, < 2, and < 5 minutes and used multivariable logistic regression to predict < 1 minute successful measurements. We conducted four testing rounds with probe modifications between rounds, and obtained 1,307 SpO2 readings. Overall, 67% (876) of measurements were successful and achieved in < 1 minute, 81% (1,059) < 2 minutes, and 90% (1,181) < 5 minutes. Compared with neonates, increasing age (infant adjusted odds ratio [aOR]; 1.87, 95% confidence interval [CI]: 1.16, 3.02; toddler aOR: 4.33, 95% CI: 2.36, 7.97; child aOR; 3.90, 95% CI: 1.73, 8.81) and being asleep versus being calm (aOR; 3.53, 95% CI: 1.89, 6.58), were associated with < 1 minute successful measurements. In conclusion, we designed a novel, reusable pediatric oximetry probe that was effectively used by LRS HCWs on children. This probe may be suitable for LRS implementation.

Fluid homeostasis in the neonate.

The physiology of the neonate is ideally suited to the transition to extrauterine life followed by a period of rapid growth and development. Intravenous fluids and electrolytes should be prescribed with care in the neonate. Sodium and water requirements in the first few days of life are low and should be increased after the postnatal diuresis. Expansion of the extracellular fluid volume prior to the postnatal diuresis is associated with poor outcomes, particularly in preterm infants. Newborn infants are prone to hypoglycemia and require a source of intravenous glucose if enteral feeds are withheld. Anemia is common, and untreated is associated with poor outcomes. Liberal versus restrictive transfusion practices are controversial, but liberal transfusion practices (accompanied by measures to minimize donor exposure) may be associated with improved long-term outcomes. Intravenous crystalloids are as effective as albumin to treat hypotension, and semi-synthetic colloids cannot be recommended at this time. Inotropes should be used to treat hypotension unresponsive to intravenous fluid, ideally guided by assessment of perfusion rather than blood pressure alone. Noninvasive methods of assessing cardiac output have been validated in neonates. More studies are required to guide fluid management in neonates, particularly in those with sepsis or undergoing surgery. A balanced salt solution such as Hartmann's or Plasmalyte should be used to replace losses during surgery (and blood or coagulation factors as indicated). Excessive fluid administration during surgery should be avoided.

Paediatric surgery and anaesthesia in south-western Uganda: a cross-sectional survey.

OBJECTIVE: to study paediatric surgery rates in south-western Uganda, compare them to rates in England, and determine if existing surgical facilities and workforce meet World Health Organization (WHO) standards. METHODS: to obtain information on surgical facilities and workforce, we conducted a cross-sectional survey of all hospitals performing major surgery in 14 districts of south-western Uganda in 2007-2008. Using theatre logbook data, we determined the surgical rates, types of surgery performed and in-theatre surgical outcomes. FINDINGS: of 72 hospitals surveyed, 29 were performing major surgery. None met WHO standards for essential surgery. There were 0.7 accredited surgeons per 100.000 population and no paediatric surgeons. Most anaesthetists were not physicians (accredited anaesthetist per 100.000 population: 1.1). The annual surgical rate for children aged ≤ 14 years was 180 operations per 100.000 population; most were emergency procedures. The annual surgical rate for patients of all ages was 652 operations per 100.000 population, with a median of 422 per operating theatre (range: 60-3497) and of 226 per surgeon (range: 60-1748). Mission or nongovernmental organization (NGO) hospitals, which had 44% of the hospital beds in the region, performed 3039 (55%) of the paediatric operations. Externally funded surgeons performed 80% of the 140 cleft lip and palate operations. Four in-theatre deaths occurred in children ≤ 14 years old (in-theatre mortality: 7.7 deaths per 10.000 operations). CONCLUSION: access to all surgery, including paediatric surgery, is poor in south-western Uganda and investment in basic health-care facilities and surgical workforce and training is urgently needed. Mission and NGO hospitals make a valuable contribution to elective surgery, and externally funded surgeons make an important contribution to specialist surgery. In-theatre mortality was lower than reported for similar settings.

Con: pediatric anesthesia training in developing countries is best achieved by out of country scholarships.

Medical migration is damaging health systems in developing countries and anesthesia delivery is critically affected, particularly in sub-Saharan Africa. 'Within country' postgraduate anesthesia training needs to be supported to encourage more doctors into the specialty. Open-ended training programs to countries that do not share the same spectrum of disease should be discouraged. Donor agencies have an important role to play in supporting sustainable postgraduate training programs.

Repair of sinus venosus defect in a patient with untreated vein of Galen aneurysmal malformation.

The vein of Galen aneurysmal malformation (VGAM) is a rare cerebral arteriovenous shunt, which may be associated with a congenital cardiac defect. Embolisation of the VGAM may be undertaken in the neonatal period if necessary, but is safer in infancy. Recent advances in neuroradiology have changed the prognosis for this group with many patients achieving survival with normal development. This case report describes a patient with a sinus venosus defect (SVD) and a VGAM and considers both the optimal timing of treatment of the two malformations and the conduct of anaesthesia for open repair of the SVD in the presence of an untreated VGAM.
