RESUMO

AIM: Over two thirds of newborn deaths occur in Africa and South Asia, and respiratory failure is a major contributor of these deaths. The exact availability of continuous positive airway pressure (CPAP) and surfactant in Africa is unknown. The aim of this study was to describe the availability of newborn respiratory care treatments in the countries of Africa. METHODS: Surveys, in English, French and Portuguese, were sent to neonatal leaders in all 48 continental countries and the two islands with populations over 1 million. RESULTS: Forty-nine (98%) countries responded. Twenty-one countries reported less than 50 paediatricians, and 12 countries had no neonatologists. Speciality neonatal nursing was recognised in 57% of countries. Most units were able to provide supplemental oxygen. CPAP was available in 63% and 67% of the most well-equipped government and private hospitals. Surfactant was available in 33% and 39% of the most well-equipped public and private hospitals, respectively. Availability of CPAP and surfactant was greatly reduced in smaller cities. Continuous oxygen saturation monitoring was only available in 33% of countries. CONCLUSION: The availability of proven life-saving interventions in Africa is inadequate. There is a need to sustainably improve availability and use of these interventions.

RESUMO

INTRODUCTION: Gestational age is a strong determinant of neonatal mortality and morbidity. Early obstetric ultrasound is the clinical reference standard, but is not widely available in many developing countries. METHODS: A prospectively designed diagnostic accuracy study in a tertiary referral hospital in a developing country. Early ultrasound (<20 weeks) was the clinical reference standard. Methods evaluated included anthropometric measurements (including foot length), vascularity of the anterior lens, the New Ballard Score and last menstrual period. Clinicians' non-structured global impression 'End of Bed' Assessment was also evaluated. RESULTS: 106 babies were included in the study. Median age at birth was 34 weeks (interquartile range 29-36). Ballard Score and 'End of Bed' Assessment had a mean bias of -0.14 and 0.06 weeks respectively but wide 95% limits of agreement. The physical component of the Ballard score, the total Ballard score and Foot length's ability to discriminate between term and preterm infants gave an area under the receiver operating characteristics curve of 0.97, 0.96 and 0.95, respectively. DISCUSSION: Although 'End of Bed' Assessment and Ballard score had small mean biases, the wide confidence intervals render the methods irrelevant in clinical practice. Foot length was particularly poor in Small for Gestational Age infants. None of the methods studied were superior to a non-structured clinician's informal 'End of Bed' Assessment. CONCLUSION: None of the methods studied met the a priori definition of clinical usefulness. Improving access to early ultrasound remains a priority. Instead of focusing on chronological accuracy, future research should compare the ability of early ultrasound and Ballard score to predict morbidity and mortality. Lay summary. BACKGROUND: Gestational age describes the time interval between conception and the delivery of the baby. Babies born before 37 weeks of gestation (preterm) or after 42 weeks of gestation (post-dates) have an increased risk of death and specific illnesses. The best way to estimate the gestational age is to perform an ultrasound scan on the mother before 20 weeks. However, this is not widely available in many developing countries. Methods to estimate gestational age after birth include calculating the time from the last period, various measurements of the child (such as weight, foot length or head circumference) physical and neurological markers of maturity and examination of the blood vessels on the lens in the eye. METHODS: In this study, we assessed how accurate these methods were when compared with the best available method; early ultrasound. We also analyzed the clinicians own personal feeling of what the most likely gestation was, based on an informal 'end of bed' assessment. If a method was to be deemed clinically useful it was agreed that it would have to confidently identify the gestation to within 1 week of the true gestation. RESULTS: None of the methods studied could confidently predict the gestational age of individual babies within 1 week. Ballard scoring and the clinician's informal 'End of Bed' Assessment were the most accurate and also had the smallest inter-operator variability when the results of two separate researchers were compared. Foot length performed particularly badly with babies who were small for their gestational age. CONCLUSION: None of the methods studied confidently predicted gestational age within a week, so have little use in clinical practice. Access to early ultrasound should be improved. Further research into the relationship between maturity markers such as the Ballard score and the rates of death and specific premature related illnesses is warranted.

RESUMO

BACKGROUND: Hyaline membrane disease contributes majorly to preterm mortality, particularly in the developing world. There are two animal-derived surfactants available in South Africa: poractant-alfa (120 mg/1.5 ml) and beractant (100 mg/4 ml). At equivalent doses, studies have shown no difference in mortality or morbidity, although there are limited data from the developing world. Both surfactants have been available for use at Groote Schuur Hospital in Cape Town but due to policy change, poractant-alfa was no longer available from November 2014. Due to weight-based dosing charts, infants who were given poractant-alfa received 20% higher dosages of phospholipid. METHODS: A before-and-after policy change non-experimental study was performed including infants from 2013 to 2015. Infants weighing <1500 g were recruited by identifying them from the surfactant register and further data were obtained from patient records. Data fields included infant weight, gestation, respiratory support and outcomes. RESULTS: Two hundred and eight infants were included. One hundred and eight received beractant and 100 received poractant-alfa. The mean birth weight was 1031 g and gestational age 28.8 weeks. Seventy-nine percent of the infants received surfactant via the INSURE (intubation, surfactant and extubation) method. The combined outcome for death or bronchopulmonary dysplasia was 35.3% in the beractant group and 36% in the poractant-alfa group (p = 0.902). All secondary outcomes including neonatal morbidities, oxygen at 28 days or length of ventilation were not statistically significant. CONCLUSION: There were no significant differences in outcomes between the two groups of infants who received different surfactants at the dosages used in our unit. This is one of the few studies of this type performed in a low- and middle-income countries.

RESUMO

BACKGROUND: Biomarkers assist in diagnosing neonatal sepsis but often provide results 6 to 48 h later. Bedside C-reactive protein (CRP) test may help to expedite clinical management. We assessed the performance of point of care test (POCT) CRP against routine laboratory analysis and determined the time difference in obtaining results. METHODS: A prospective observational study was conducted over 4 months. Neonates clinically indicated, had CRP simultaneously tested using the POCT and laboratory assays. RESULTS: Using similar decision cut-off values of 10 mg/l, POCT compared favourably to laboratory testing. The median times to POCT result was 4 min whereas laboratory results were entered at a median of 4.1 h (95th percentile 8 h) but only checked after 5.5 h (95th percentile 19.8 h). CONCLUSIONS: POCT may be a quick and reliable method to determine CRP. It may rationalize antibiotic usage, allow for earlier patient discharge and reduce overall patient management cost.

RESUMO

The use of donor human breast milk instead of formula reduces the risk of necrotising enterocolitis in preterm infants when their mother's own milk is insufficient. Use of donor milk is limited by the cost of establishing a milk bank and a lack of donors, but the optimal rationing of limited donor milk is unclear. This paper uses an economic model to explore how a limited donor milk supply should be allocated across very low birthweight infants in South Africa considering 2 outcomes: maximising lives saved and minimising costs. We developed a probabilistic cohort Markov decision model with 10,000 infants across 4 birthweight groups. We evaluated allocation scenarios in which infants in each group could be exclusively formula-fed or fed donor milk for 14 or 28 days and thereafter formula until death or discharge. Prioritising infants in the lowest birthweight groups would save the most lives, whereas prioritising infants in the highest birthweight groups would result in the highest cost savings. All allocation scenarios would be considered very cost-effective in South Africa compared to the use of formula; the "worst case" was $619 per Disability Adjusted Life Year averted. There is a compelling argument to increase the supply of donor milk in middle-income countries. Our analysis could be extended by taking a longer term perspective, using data from more than one country and exploring the use of donor milk as an adjunct to mother's own milk, rather than a pure substitute for it.

RESUMO

BACKGROUND: Optimal feeding regimens for infants ≤ 1000 g have not been established and are a global healthcare concern. AIMS AND OBJECTIVES: A controlled trial to establish the safety and efficacy of high vs low volume initiation and rapid vs slow advancement of milk feeds in a resource-limited setting was undertaken. METHODS: Infants ≤ 1000 g birthweight were randomised to one of four arms, either low (4 ml/kg/day) or high (24 ml/kg/day) initiation and either slow (24 ml/kg/day) or rapid (36 ml/kg/day) advancement of exclusive feeds of human milk (mother's or donor) until a weight of 1200 g was reached. After this point, formula was used to supplement insufficient mother's milk. The primary outcome was time to reach 1500 g. RESULTS: infants were recruited (51: low/slow; 47: low/rapid; 52: high/slow; 50: high/rapid). Infants on rapid advancement regimens reached 1500 g most rapidly (hazard ratio 1.48, 95% CI 1.05-2.09, P=0.03). The rapid advancement groups also regained birthweight more rapidly (hazard ratio 1.77, 95% CI 1.26-2.50, P=0.001). There was no apparent effect of high vs low initiation volumes but there was some evidence of interaction between interventions. There were no significant differences in other secondary outcomes, including necrotising enterocolitis, feed intolerance and late-onset sepsis. CONCLUSIONS: In this small pilot study, higher initiation feed volumes and larger daily increments appeared to be well tolerated and resulted in more rapid early weight gain. These data provide justification for a larger study in resource-limited settings to address mortality, necrotising enterocolitis and other important outcomes.

RESUMO

BACKGROUND: Blood cultures are the most direct method of detecting bacteraemia. Reducing contamination rates improves the specificity and positive predictive value of the blood culture. Clinical performance dashboards have been shown to be powerful tools in improving patient care and outcomes. OBJECTIVES: To determine whether prospective surveillance of bloodstream infections (BSIs), introduction of an educational intervention and the use of a clinical performance dashboard could reduce BSIs and blood culture contamination rates in a neonatal nursery. METHODS: We compared two time periods, before and after an intervention. Blood culture data were extracted from the local microbiology laboratory database. The educational intervention included the establishment of hand-washing protocols, blood culture techniques and video tools. A clinical performance dashboard was developed to demonstrate the monthly positive blood culture and contamination rates, and this was highlighted and referred to weekly at the unit staff meeting. RESULTS: Before the intervention, 1 460 blood cultures were taken; 206 (14.1%) were positive, of which 104 (7.1% of the total) were contaminants. In the period following the intervention, 1 282 blood cultures were taken; 131 (10.2%) were positive, of which 42 (3.3% of the total) were contaminants. The number of positive blood cultures and contamination rates after the intervention were both statistically significantly reduced (p=0.002 and p<0.001, respectively). CONCLUSION: This study demonstrates that adopting a relatively simple educational tool, making use of a clinical performance dashboard indicator and benchmarking practice can significantly reduce the level of neonatal sepsis while also reducing contaminated blood cultures.

RESUMO

BACKGROUND: An early clinical score predicting an abnormal amplitude-integrated electroencephalogram (aEEG) or moderate-severe hypoxic ischemic encephalopathy (HIE) may allow rapid triage of infants for therapeutic hypothermia. We aimed to determine if early clinical examination could predict either an abnormal aEEG at age 6 hours or moderate-severe HIE presenting within 72 hours of birth. METHODS: Sixty infants ≥ 36 weeks gestational age were prospectively enrolled following suspected intrapartum hypoxia and signs of encephalopathy. Infants who were moribund, had congenital conditions that could contribute to the encephalopathy or had severe cardio-respiratory instability were excluded. Predictive values of the Thompson HIE score, modified Sarnat encephalopathy grade (MSEG) and specific individual signs at age 3-5 hours were calculated. RESULTS: All of the 60 infants recruited had at least one abnormal primitive reflex. Visible seizures and hypotonia at 3-5 hours were strongly associated with an abnormal 6-hour aEEG (specificity 88% and 92%, respectively), but both had a low sensitivity (47% and 33%, respectively). Overall, 52% of the infants without hypotonia at 3-5 hours had an abnormal 6-hour aEEG. Twelve of the 29 infants (41%) without decreased level of consciousness at 3-5 hours had an abnormal 6-hour aEEG (sensitivity 67%; specificity 71%). A Thompson score ≥ 7 and moderate-severe MSEG at 3-5 hours, both predicted an abnormal 6-hour aEEG (sensitivity 100 vs. 97% and specificity 67 vs. 71% respectively). Both assessments predicted moderate-severe encephalopathy within 72 hours after birth (sensitivity 90%, vs. 88%, specificity 92% vs. 100%). The 6-hour aEEG predicted moderate-severe encephalopathy within 72 hours (sensitivity 75%, specificity 100%) but with lower sensitivity (p = 0.0156) than the Thompson score (sensitivity 90%, specificity 92%). However, all infants with a normal 3- and 6-hour aEEG with moderate-severe encephalopathy within 72 hours who were not cooled had a normal 24-hour aEEG. CONCLUSIONS: The encephalopathy assessment described by the Thompson score at age 3-5 hours is a sensitive predictor of either an abnormal 6-hour aEEG or moderate-severe encephalopathy presenting within 72 hours after birth. An early Thompson score may be useful to assist with triage and selection of infants for therapeutic hypothermia.

RESUMO

BACKGROUND: Recent newborn resuscitation guidelines recommend therapeutic hypothermia (TH) as a treatment to reduce long-term neurological deficit in hypoxic ischemic encephalopathy (HIE) survivors. In South Africa, varied resource constraints may present difficulties in the implementation of TH. OBJECTIVE: To determine the opinions and practice of South African pediatricians, regarding TH and the management of HIE. METHODS: We invited 288 South African pediatricians and neonatologists to participate in a web-based survey by e-mail. Practitioners were identified using the Medpages™ database. RESULTS: Responses were received from 37.8% of the e-mails. Seventy-six percent of respondents stated that hypothermia was either effective or very effective while 4% stated TH was ineffective in the management of HIE. Only 42% of respondents offered TH and a further 9% transferred patients to other units for cooling. Twenty-four percent had not implemented TH nor planned to introduce it into practice in the near future. Ninety-eight percent of respondents stated TH should be the standard of care in tertiary neonatal units. CONCLUSION: Most pediatricians in South Africa who responded to the survey stated that TH is effective to reduce the neurological deficit in HIE, however, less than half offered it as a treatment.

RESUMO

Fetal goitrous hypothyroidism is a rare condition in euthyroid pregnant women. Complications such as tracheal and esophageal compression with resultant polyhydramnios, as well as the possibility of neurodevelopmental effects of hypothyroidism, have prompted prenatal treatment with intra-amniotic L-thyroxine. We report a case of this condition and its in utero management.

RESUMO

OBJECTIVES: To determine the need for resuscitation at the birth of babies delivered by elective caesarean section (CS) and to record the time spent by doctors attending such deliveries. METHODS: Data were collected prospectively on all elective CSs performed at Groote Schuur Hospital over a 3-month period. Data collected included: total time involved for paediatrician from call to leaving theatre, management of infant (requiring any form of resuscitation), Apgar scores and neonatal outcome (e.g. admission to nursery). The CSs were classified as low-risk or high-risk (multiple pregnancy, prematurity, growth restriction, abnormal lie, general anaesthetic or known congenital abnormality). RESULTS: Data were recorded for 138 deliveries. Three were excluded as they were not elective CS. One hundred and fifteen deliveries were classified as uncomplicated and 20 as high-risk. Only 1 of the babies born from the 115 low-risk CSs needed brief resuscitation, whereas 9 of the 20 high-risk deliveries resulted in newborn resuscitation. The reasons for low-risk CS were: previous CS (81); infant of diabetic mother (IDM) and previous CS (16); IDM alone (6); estimated big baby (10); and other (2).The average time spent at each elective CS by the pediatrician was 37 minutes. CONCLUSION: For low-risk CS, the same medical attendance (i.e. a midwife) as for an uncomplicated NVD would be appropriate; this can free a doctor for other duties, and assist in de-medicalising a low-risk procedure.
