RESUMO

INTRODUCTION: Facemask ventilation is a crucial, but challenging, element of neonatal resuscitation.In a previously reported study, instructor-led training using a novel neonatal simulator resulted in high-level ventilation competence for health care providers (HCPs) involved in newborn resuscitation. The aim of this study was to identify the optimal frequency and dose of simulation training to maintain this competence level. METHODS: Prospective observational study of HCPs training through 9 months. All training was logged. Overall ventilation competence scores were calculated for each simulation case, incorporating 7 skill elements considered important for effective ventilation.Overall scores and skill elements were analyzed by generalized linear mixed effects models using frequency (number of months of 9 where training occurred and total number of training sessions in 9 months) and dose (total number of cases performed) as predictors. Training loads (frequency + dose) predictive of high scores were projected based on estimated marginal probabilities of successful outcomes. RESULTS: A total of 156 HCPs performed 4348 training cases. Performing 5 or more sessions in 9 months predicted high global competence scores (>28/30). Frequency was the best predictor for 4 skill elements; success in maintaining airway patency and ventilation fraction was predicted by performing training in, respectively, 2 and 3 months of 9, whereas for avoiding dangerously high inflating pressures and providing adequate mask seal, 5 and 6 sessions, respectively, over the 9 months, predicted success. Skills reflecting global performance (successful resuscitation and valid ventilations) and ventilation rate were more dose-dependent. CONCLUSIONS: Training frequency is important in maintaining neonatal ventilation competence. Training dose is important for some skill elements. This offers the potential for individualized training schedules.

RESUMO

BACKGROUND: The burden of stillbirth, neonatal and maternal deaths are unacceptably high in low- and middle-income countries, especially around the time of birth. There are scarce resources and/or support implementation of evidence-based training programs. SaferBirths Bundle of Care is a well-proven package of innovative tools coupled with data-driven on-the-job training aimed at reducing perinatal and maternal deaths. The aim of this project is to determine the effect of scaling up the bundle on improving quality of intrapartum care and perinatal survival. METHODS: The project will follow a stepped-wedge cluster implementation design with well-established infrastructures for data collection, management, and analysis in 30 public health facilities in regions in Tanzania. Healthcare workers from selected health facilities will be trained in basic neonatal resuscitation, essential newborn care and essential maternal care. Foetal heart rate monitors (Moyo), neonatal heart rate monitors (NeoBeat) and skills trainers (NeoNatalie Live) will be introduced in the health facilities to facilitate timely identification of foetal distress during labour and improve neonatal resuscitation, respectively. Heart rate signal-data will be automatically collected by Moyo and NeoBeat, and newborn resuscitation training by NeoNatalie Live. Given an average of 4000 baby-mother pairs per year per health facility giving an estimate of 240,000 baby-mother pairs for a 2-years duration, 25% reduction in perinatal mortality at a two-sided significance level of 5%, intracluster correlation coefficient (ICC) to be 0.0013, the study power stands at 0.99. DISCUSSION: Previous reports from small-scale Safer Births Bundle implementation studies show satisfactory uptake of interventions with significant improvements in quality of care and lives saved. Better equipped and trained birth attendants are more confident and skilled in providing care. Additionally, local data-driven feedback has shown to drive continuous quality of care improvement initiatives, which is essential to increase perinatal and maternal survival. Strengths of this research project include integration of innovative tools with existing national guidelines, local data-driven decision-making and training. Limitations include the stepwise cluster implementation design that may lead to contamination of the intervention, and/or inability to address the shortage of healthcare workers and medical supplies beyond the project scope.

RESUMO

AIM OF THE STUDY: Describe the distribution of the first recorded heart rate (HR) in apnoeic term/near-term newborns, HR responses to basic resuscitation (no intubation, chest compressions and/or medication), and relationship to 24-h outcomes. We also document patient characteristics and care provider behaviour stratified by first HR. METHODS: Descriptive study from July 2013 through June 2018 at Haydom Hospital in Tanzania. All deliveries were observed by assistants recording data. Bag-mask ventilation and ECG data were recorded by resuscitation monitors. Newborns with ≥5 ventilations and ECG signal-data were included. RESULTS: 1237 term/near-term newborns with median (25th, 75th percentiles) gestation 38 (37, 40) weeks and birth weight 3140 (2750, 3500) grams fulfilled inclusion criteria. The first HR, measured median 102 (73, 144) s after birth following drying/stimulation, was distributed into two peaks with centres around 60 and 165 bpm, 51% were ≥100 bpm. After ventilation, the HR distribution shifted to a single-peak, with median 161 bpm. At least one low-high HR transition crossing 100 bpm was noted in 44% of newborns. The HR increase occurred over median 9.2 (6.2, 13) s, was 60 (43, 77) bpm, and 86% followed a ventilation sequence of 23 (16, 34) s duration. 72% of the newborns with first HR < 60 bpm survived following ventilations only. Both first and final HR were significantly related to 24-h outcomes. CONCLUSIONS: The first recorded HR was distributed into two peaks on each side of 100 bpm. Ventilation increased HR in most newborns. Lower first and final HR were related to gradually more adverse 24-h outcomes.

RESUMO

BACKGROUND: Approximately 40,000 newborns die each year in Tanzania. Regional differences in outcome are common. Reviewing current local data, as well as defining potential causal pathways leading to death are urgently needed, before targeted interventions can be implemented. OBJECTIVE: To describe the clinical characteristics and potential causal pathways contributing to newborn death and determine the presumed causes of newborn mortality within seven days, in a rural hospital setting. METHODS: Prospective observational study of admitted newborns born October 2014-July 2017. Information about labour/delivery and newborn management/care were recorded on data collection forms. Causes of deaths were predominantly based on clinical diagnosis. RESULTS: 671 were admitted to a neonatal area. Reasons included prematurity n = 213 (32%), respiratory issues n = 209 (31%), meconium stained amniotic fluid with respiratory issues n = 115 (17%) and observation for < 24 hours n = 97 (14%). Death occurred in 124 infants. Presumed causes were birth asphyxia (BA) n = 59 (48%), prematurity n = 19 (15%), presumed sepsis n = 19 (15%), meconium aspiration syndrome (MAS) n = 13 (10%) and congenital abnormalities n = 14 (11%). More newborns who died versus survivors had oxygen saturation <60% on admission (37/113 vs 32/258; p≤0.001) respectively. Moderate hypothermia on admission was common i.e. deaths 35.1 (34.6-36.0) vs survivors 35.5 (35.0-36.0)°C (p≤0.001). Term newborns who died versus survivors were fourfold more likely to have received positive pressure ventilation after birth i.e. 4.57 (1.22-17.03) (p<0.02). CONCLUSION: Intrapartum-related complications (BA, MAS), prematurity, and presumed sepsis were the leading causes of death. Intrapartum hypoxia, prematurity and attendant complications and presumed sepsis, are major pathways leading to death. Severe hypoxia and hypothermia upon admission are additional contributing factors. Strategies to identify fetuses at risk during labour e.g. improved fetal heart rate monitoring, coupled with timely interventions, and implementation of WHO interventions for preterm newborns, may reduce mortality in this low resource setting.

RESUMO

BACKGROUND: Regular fetal heart rate monitoring during labor can drastically reduce fresh stillbirths and neonatal mortality through early detection and management of fetal distress. Fetal monitoring in low-resource settings is often inadequate. An electronic strap-on fetal heart rate monitor called Moyo was introduced in Tanzania to improve intrapartum fetal heart rate monitoring. There is limited knowledge about how skilled birth attendants in low-resource settings perceive using new technology in routine labor care. This study aimed to explore the attitude and perceptions of skilled birth attendants using Moyo in Dar es Salaam, Tanzania. METHODS: A qualitative design was used to collect data. Five focus group discussions and 10 semi-structured in-depth interviews were carried out. In total, 28 medical doctors and nurse/midwives participated in the study. The data was analyzed using qualitative content analysis. RESULTS: The participants in the study perceived that the device was a useful tool that made it possible to monitor several laboring women at the same time and to react faster to fetal distress alerts. It was also perceived to improve the care provided to the laboring women. Prior to the introduction of Moyo, the participants described feeling overwhelmed by the high workload, an inability to adequately monitor each laboring woman, and a fear of being blamed for negative fetal outcomes. Challenges related to use of the device included a lack of adherence to routines for use, a lack of clarity about which laboring women should be monitored continuously with the device, and misidentification of maternal heart rate as fetal heart rate. CONCLUSION: The electronic strap-on fetal heart rate monitor, Moyo, was considered to make labor monitoring easier and to reduce stress. The study findings highlight the importance of ensuring that the device's functions, its limitations and its procedures for use are well understood by users.

RESUMO

In an effort to reduce newborn mortality, a newly developed strap-on electronic fetal heart rate monitor was introduced at several health facilities in Tanzania in 2015. Training sessions were organized to teach staff how to use the device in clinical settings. This study explores skilled birth attendants' perceptions and experiences acquiring and transferring knowledge about the use of the monitor, also called Moyo. Knowledge about this learning process is crucial to further improve training programs and ensure correct, long-term use. Five Focus group discussions (FGDs) were carried out with doctors and nurse-midwives, who were using the monitor in the labor ward at two health facilities in Tanzania. The FGDs were analyzed using qualitative content analysis. The study revealed that the participants experienced the training about the device as useful but inadequate. Due to high turnover, a frequently mentioned challenge was that many of the birth attendants who were responsible for training others, were no longer working in the labor ward. Many participants expressed a need for refresher trainings, more practical exercises and more theory on labor management. The study highlights the need for frequent trainings sessions over time with focus on increasing overall knowledge in labor management to ensure correct use of the monitor over time.

RESUMO

BACKGROUND: Intrapartum Fetal Heart Rate (FHR) monitoring is crucial for the early detection of abnormal FHR, facilitating timely obstetric interventions and thus the potential reduction of adverse perinatal outcomes. We explored midwifery practices of intrapartum FHR monitoring pre and post implementation of a novel continuous automatic Doppler device (the Moyo). METHODOLOGY: A pre/post observational study among low-risk pregnancies at a tertiary hospital was conducted from March to December 2016. In the pre-implementation period, intermittent monitoring was conducted with a Pinard stethoscope (March to June 2016, n = 1640 women). In the post-implementation period, Moyo was used for continuous FHR monitoring (July-December 2016, n = 2442 women). The primary outcome was detection of abnormal FHR defined as absent, FHR<120or FHR>160bpm. The secondary outcomes were rates of assessment/documentation of FHR, obstetric time intervals and intrauterine resuscitations. Chi-square test, Fishers exact test, t-test and Mann-Whitney U test were used in bivariate analysis whereas binary and multinomial logistic regression were used for multivariate. RESULTS: Moyo use was associated with greater detection of abnormal FHR (8.0%) compared with Pinard (1.6%) (p<0.001). There were higher rates of non-assessment/documentation of FHR pre- (45.7%) compared to post-implementation (2.2%) (p<0.001). At pre-implementation, 8% of deliveries had FHR documented as often as ≤ 60 minutes, compared to 51% post-implementation (p<0.001). Implementation of continuous FHR monitoring was associated with a shorter time interval from the last FHR assessment to delivery i.e. median (IQR) of 60 (30,100) to 45 (21,85) minutes (p<0.001); and shorter time interval between each FHR assessment i.e. from 150 (86,299) minutes to 60 (41,86) minutes (p<0.001). Caesarean section rates increased from 2.6 to 5.4%, and vacuum deliveries from 2.2 to 5.8% (both p<0.001). Perinatal outcomes i.e. fresh stillbirths and early neonatal deaths were similar between time periods. The study was limited by both lack of randomization and involvement of low-risk pregnant women with fewer adverse perinatal outcomes than would be expected in a high-risk population. CONCLUSION: Implementation of the Moyo device, which continuously measures FHR, was associated with improved quality in FHR monitoring practices and the detection of abnormal FHR. These improvements led to more frequent and timely obstetric responses. Follow-up studies in a high-risk population focused on a more targeted description of the FHR abnormalities and the impact of intrauterine resuscitation is a critical next step in determining the effect on reducing perinatal mortality.

RESUMO

OBJECTIVE: To compare the frequency of abnormal fetal heart rate (FHR) detection between continuous Doppler and intermittent fetoscope monitoring. METHOD: A randomized controlled open-label trial was conducted between February 1, 2016, and January 31, 2017, at Haydom Lutheran hospital, Tanzania. Women in active labor with singleton pregnancies and normal FHR at admission were randomly allocated in a 1:1 ratio to receive either continuous or intermittent FHR monitoring. The primary outcome was abnormal FHR detection. RESULTS: 2652 women were enrolled; 1340 received continuous monitoring and 1312 received intermittent monitoring. Continuous FHR monitoring detected abnormal FHR in 108 (8.1%) participants versus 40 (3.0%) participants in the intermittent monitoring group (risk ratio [RR] 2.64, 95% confidence interval [CI] 1.8-3.7; P<0.001). The increased detection rate in the continuous versus intermittent monitoring group was associated with an increase in rate of subsequent intrauterine resuscitations (89 [6.6%] vs 42 [3.2%]; RR 2.07, 95% CI 1.4-2.9; P<0.001). In total, 92 (3.5%) infants had adverse perinatal outcomes, with no significant differences between groups. CONCLUSION: Continuous FHR monitoring increased identification of abnormal FHR and subsequent intrauterine resuscitations. ClinicalTrials.gov: NCT02790814.

RESUMO

BACKGROUND: Effective positive pressure ventilation (PPV) of non-breathing newborns is crucial in facilitating cardio-respiratory adaptation at birth. Identifying predictors of death in newborns receiving PPV is important in order to facilitate preventative strategies. OBJECTIVE: The objective of this study was to determine the perinatal predictors of death including the quality of PPV administered among admitted newborns. METHODS: An observational study of admitted newborns who received PPV after birth was conducted. Research assistants observed all deliveries and recorded perinatal events on data collection forms. Measured heart rate (HR) and ventilation parameters were then compared between newborns who died and survivors. RESULTS: Newborns (n = 232) were studied between October 2014 and November 2016. Newborns who died (n = 53) compared to survivors (n = 179) had more fetal heart rate (FHRT) abnormalities (12/53 vs 19/179; p = 0.03); lower initial HR (<100 beats/minute) at start of PPV (44/48 vs 77/139; p<0.001); and a longer time for HR to increase >100 beats/minute from birth (180 vs 149 seconds; p = 0.07). Newborns who died compared to survivors took longer time (14 vs 4 seconds; p = 0.008) and more inflations (7 vs 3; p = 0.006) to achieve an expired volume (Vt) of 6 ml/kg, respectively. Median delivered Vt during the first 60 seconds of PPV was less in newborns who died compared to survivors (5 vs 6 ml/kg; p = 0.12). Newborns who died proceeded to severe encephalopathy (15/31 vs 1/59; p<0.001) compared to survivors. CONCLUSION: Depressed newborns who proceeded to death compared to survivors, exhibited delayed HR response to PPV which may partly reflect FHRT abnormalities related to interruption of placental blood flow, and/or a timely delay in establishing adequate Vt. Depressed newborns progressed to moderate/severe encephalopathy. Improving FHRT monitoring to identify fetuses at risk for expedited delivery, coupled with optimizing delivery room PPV might decrease mortality in this setting.

RESUMO

BACKGROUND: Fetal stethoscopes are mainly used for intermittent monitoring of fetal heart rate (FHR) during labor in low-income countries, where perinatal mortality is still high. Handheld Dopplers are rarely available and are dependent on batteries or electricity. The objective was to compare the Pinard stethoscope versus a new wind-up handheld Doppler in the detection of abnormal FHR. MATERIALS AND METHODS: We conducted a randomized controlled study at Muhimbili National Hospital, Tanzania, from April 2013 to September 2015. Women with gestational age ≥37 weeks, cephalic presentation, normal FHR on admission, and cervical dilatation <7 cm were included. Primary outcome was abnormal FHR detection (<120 or >160 beats/min). Secondary endpoints were time to delivery, mode of delivery, and perinatal outcomes. χ2, Fisher's exact test, Mann-Whitney test, and logistic regression were conducted. Unadjusted and adjusted odds ratios were calculated with respective 95% confidence interval. RESULTS: In total, 2,844 eligible women were assigned to FHR monitoring with Pinard (n=1,423) or Doppler (n=1,421). Abnormal FHRs were more often detected in the Doppler (6.0%) versus the Pinard (3.9%) arm (adjusted odds ratio =1.59, 95% confidence interval: 1.13-2.26, p=0.008). Median (interquartile range) time from abnormal FHR detection to delivery was comparable between Doppler and Pinard, ie, 80 (60,161) and 89 (52,165) minutes, respectively, as was the incidence of cesarean delivery (12.0% versus 12.2%). The incidence of adverse perinatal outcomes (fresh stillbirths, 24-hour neonatal admissions, and deaths) was similar overall; however, among newborns with abnormal FHR delivered vaginally, adverse outcomes were less incident in Doppler (7 of 43 births, 16.3%) than in the Pinard arm (10 of 23 births, 43.5%), p=0.021. CONCLUSION: Intermittent FHR monitoring using Doppler was associated with an increased detection of abnormal FHR compared to Pinard in a low-risk population. Time intervals from abnormal FHR detection to delivery were longer than recommended in both arms. Perinatal outcomes were better among vaginally delivered newborns with detected abnormal FHR in the Doppler arm.

RESUMO

Implementation of basic neonatal resuscitation in low- and middle-income settings consistently saves lives on the day of birth. What can be done to extend these gains and further improve the outcomes of infants who require resuscitation at birth when resources are limited? This review considers how resuscitation and post-resuscitation care can advance to help meet the survival goals of the Every Newborn Action Plan for 2030. A brief summary of the evidence for benefit from basic neonatal resuscitation training in low- and middle-income countries highlights key aspects of training, low-dose high-frequency practice, and implementation with single providers or teams. Reorganization of processes of care, as well as new equipment for training and selected clinical interventions can support further quality improvement in resuscitation. Consideration of the resuscitation algorithm itself focuses on important actions for all babies and special considerations for small babies and those not crying after thorough drying. Finally, an examination of the vital elements of assessment and continued stabilization/care in the health facility draws attention to the opportunities for prevention of intrapartum-related events and the gaps that still exist in postnatal care. Extending and improving implementation of basic resuscitation to make it available to all newborns will assure continued benefit to the largest numbers; once high coverage and quality of basic resuscitation are achieved, health systems with maturing capacity can extend survival gains with improved prevention, more advanced resuscitative interventions, and strengthened postnatal care.

RESUMO

BACKGROUND: Neonatal mortality is a global challenge, with an estimated 1.3 million intrapartum stillbirths in 2015. The majority of these were found in low resource settings with limited options to intrapartum fetal heart monitoring devices. This trial compared frequency of abnormal fetal heart rate (FHR) detection and adverse perinatal outcomes (i.e. fresh stillbirths, 24-h neonatal deaths, admission to neonatal care unit) among women intermittently assessed by Doppler or fetoscope in a rural low-resource setting. METHODS: This was an open-label randomized controlled trial conducted at Haydom Lutheran Hospital from March 2013 through August 2015. Inclusion criteria were; women in labor, singleton, cephalic presentation, normal FHR on admission (120-160 beats/minute), and cervical dilatation ≤7 cm. Verbal consent was obtained. RESULTS: A total of 2684 women were recruited, 1309 in the Doppler and 1375 in the fetoscope arms, respectively. Abnormal FHR was detected in 55 (4.2%) vs 42 (3.1%). (RR = 1.38; 95%CI: 0.93, 2.04) in the Doppler and fetoscope arms, respectively. Bag mask ventilation was performed in 80 (6.1%) vs 82 (6.0%). (RR = 1.03; 95%CI: 0.76, 1.38) of neonates, and adverse perinatal outcome was comparable 32(2.4%) vs 35(2.5%). (RR = 0.9; 95%CI: 0.59, 1.54), in the Doppler and fetoscope arms, respectively. CONCLUSION: This trial failed to demonstrate a statistically significant difference in the detection of abnormal FHR between intermittently used Doppler and fetoscope and adverse perinatal outcomes. However, FHR measurements were not performed as often as recommended by international guidelines. Conducting a randomized controlled study in rural settings with limited resources is associated with major challenges. TRIAL REGISTRATION: This clinical trial was registered on April 2013 with registration number NCT01869582 .

RESUMO

BACKGROUND: Preterm neonatal mortality (NM) has remained high and unchanged for many years in Tanzania, a resource-limited country. Major causes of mortality include birth asphyxia, respiratory insufficiency and infections. Antenatal corticosteroids (ACS) have been shown to significantly reduce mortality in developed countries. There is inconsistent use of ACS in Tanzania. OBJECTIVE: To determine whether implementation of a care bundle that includes ACS, maternal antibiotics (MA), neonatal antibiotics (NA) and avoidance of moderate hypothermia (temperature < 36°C) targeting infants of estimated gestational age (EGA) 28 to 34 6/7 weeks would reduce NM (< 7 days) by 35%. METHODS: A Pre (September 2014 to May 2015) and Post (June 2015 to June 2017) Implementation strategy was used and introduced at three University-affiliated and one District Hospital. Dexamethasone, as the ACS, was added to the national formulary in May 2015, facilitating its free use down to the district level. FINDINGS: NM was reduced 26% from 166 to 122/1000 livebirths (P = 0.005) and fresh stillbirths (FSB) 33% from 162/1000 to 111/1000 (p = 0.0002) Pre versus Post Implementation. Medications including combinations increased significantly at all sites (p<0.0001). By logistic regression, combinations of ACS, maternal and NA (odds ratio (OR) 0.33), ACS and NA (OR 0.30) versus no treatment were significantly associated with reduced NM. NM significantly decreased per 250g birthweight increase (OR 0.59), and per one week increase in EGA (OR 0.87). Moderate hypothermia declined pre versus post implementation (p<0.0001) and was two-fold more common in infants who died versus survivors. INTERPRETATION: A low-cost care bundle, ~$6 per patient, was associated with a significant reduction in NM and FSB rates. The former presumably by reducing respiratory morbidity with ACS and minimizing infections with antibiotics. If these findings can be replicated in other resource-limited settings, the potential for further reduction of <5 year mortality rates becomes enormous.

RESUMO

To increase labor monitoring and prevent neonatal morbidity and mortality, a new wireless, strap-on electronic fetal heart rate monitor called Moyo was introduced in Tanzania in 2016. As part of the ongoing evaluation of the introduction of the monitor, the aim of this study was to explore the attitudes and perceptions of women who had worn the monitor continuously during their most recent delivery and perceptions about how it affected care. This knowledge is important to identify barriers towards adaptation in order to introduce new technology more effectively. We carried out 20 semi-structured individual interviews post-labor at two hospitals in Tanzania. A thematic content analysis was used to analyze the data. Our results indicated that the use of the monitor positively affected the women's birth experience. It provided much-needed reassurance about the wellbeing of the child. The women considered that wearing Moyo improved care due to an increase in communication and attention from birth attendants. However, the women did not fully understand the purpose and function of the device and overestimated its capabilities.

RESUMO

OBJECTIVE: To characterize, among non-breathing flaccid neonates at delivery, immediate heartrate and responses to ventilation in relation to the clinical diagnosis of fresh stillbirth (FSB) or early neonatal death (END) within 24 hours. METHODS: The present cross-sectional study included all deliveries at Haydom Hospital in rural Tanzania between July 1, 2013, and July 31, 2016. Ventilation parameters and heartrate were recorded by monitors with ventilation and dry-electrocardiography sensors. Perinatal characteristics were recorded on data forms by trained research assistants. RESULTS: Among 12 789 neonates delivered, 915 were ventilated; among ventilated neonates, there were 53 (6%) FSBs and 64 (7%) ENDs. Electrocardiography was used in 46 FSBs and 55 ENDs, and these neonates were included in a subanalysis. Initial heartrate was detected in 27 (59%) of 46 FSBs and 52 (95%) of 55 ENDs, and was lower in FSBs (52 ± 19 vs 76 ± 37 bpm; P=0.003). More ENDs responded to ventilation (53% vs 9%; P<0.001), with heartrate increasing above 100 bpm. Heartrate at ventilation discontinuation was higher among ENDs (115 ± 49 vs 52 ± 33 bpm; P<0.001). CONCLUSION: Progression to FSB or END after intrapartum hypoxia/anoxia is probably part of the same circulatory end-process. Distinguishing FSB from severely asphyxiated newborns is clinically difficult and probably influences estimated global perinatal mortality rates.

RESUMO

Globally, the burden of deaths and illness is still unacceptably high at the day of birth. Annually, approximately 300.000 women die related to childbirth, 2.7 million babies die within their first month of life, and 2.6 million babies are stillborn. Many of these fatalities could be avoided by basic, but prompt care, if birth attendants around the world had the necessary skills and competencies to manage life-threatening complications around the time of birth. Thus, the innovative Helping Babies Survive (HBS) and Helping Mothers Survive (HMS) programs emerged to meet the need for more practical, low-cost, and low-tech simulation-based training. This paper provides users of HBS and HMS programs a 10-point list of key implementation steps to create sustained impact, leading to increased survival of mothers and babies. The list evolved through an Utstein consensus process, involving a broad spectrum of international experts within the field, and can be used as a means to guide processes in low-resourced countries. Successful implementation of HBS and HMS training programs require country-led commitment, readiness, and follow-up to create local accountability and ownership. Each country has to identify its own gaps and define realistic service delivery standards and patient outcome goals depending on available financial resources for dissemination and sustainment.

RESUMO

BACKGROUND: Every year, an estimated 10 million babies are born, non-breathing and in need of resuscitation. Advances in management have been made over the past decades, however, approximately 700.000 yearly deaths result from this global problem. A prototype newborn resuscitation monitor (NRM) (Laerdal Global Health, Stavanger, Norway) has been developed with the purpose of studying newborn resuscitation. The monitor has the ability to continuously display HR using dry electrode ECG technology, to measure tidal volume, pressure and end tidal CO2, and to store the results for later analysis. Such monitor could enhance the care providers performance, and hence survival of neonates, by displaying the quality and response of the given care. The aim of this preclinical study was to describe the abilities of the NRM to measure ventilation and heart rate parameters against pathophysiological responses to different induced conditions in a piglet i.e. increased deadspace, pressure and washout of surfactant. METHODS: Piglets were chosen for the study, as they have tidal volumes of approximately 6 ml/kg, resembling the human neonate. Five piglets were anesthetized and intubated before starting positive pressure ventilation (PPV). The dry electrode ECG sensor of the NRM was placed over the abdomen, and experiments performed: (1) inducing different ventilation scenarios and (2) lavage of surfactant. RESULTS: The NRM was capable of continuously displaying HR and detecting inflicted changes in ventilation and compliance of piglets. It could measure inflated and exhaled volume, the pressure of the ventilations and also the end tidal CO2. CONCLUSIONS: The NRM provides objective feedback in anesthetized animals, and may be used in clinical studies and hopefully generate new knowledge on neonatal transition and resuscitation. The monitor may be further developed for use in both low and high-resource settings.

RESUMO

As rates of childhood mortality decline, neonatal deaths account for nearly half of under-5 deaths worldwide. Intrapartum-related events (birth asphyxia) contribute to approximately one-quarter of neonatal deaths, many of which can be prevented by simple resuscitation and newborn care interventions. This paper reviews various lines of research that have influenced the global neonatal resuscitation landscape. A brief situational analysis of asphyxia-related newborn mortality in low-resource settings is linked to renewed efforts to reduce neonatal mortality in the Every Newborn Action Plan. Possible solutions to gaps in care are identified. Building on international scientific evidence, tests of educational efficacy, and community-based trials established the feasibility and effectiveness of training in resource-limited settings and identified successful implementation strategies. Implementation of neonatal resuscitation programs has been shown to decrease intrapartum stillbirth rates and early neonatal mortality. Challenges remain with respect to provider competencies, coverage, and quality of interventions. The combination of resuscitation science, strategies to increase educational effectiveness, and implemention of interventions with high coverage and quality has resulted in reduced rates of asphyxia-related neonatal mortality. Further efforts to improve coverage and implementation of neonatal resuscitation will be necessary to meet the 2035 goal of eliminating preventable newborn deaths.
