Dealing with neonatal emergencies in low-resource settings

We describe the development and delivery of neonatal care including trends and impacts of major interventions on neonatal mortality particularly in low-resource settings. Low- and middle-income countries continue to be major contributors to neonatal mortality. Although there has been progress in reducing neonatal mortality, neonatal deaths are contributing an increasing percentage of childhood mortality. Several interventions targeting neonatal care such as neonatal resuscitation and essential newborn care have contributed to improved outcomes. However, there are still many neonatal deaths that are preventable with known effective interventions. This review addresses interventions proven effective in reducing neonatal mortality, challenges to implement them, and future directions of implementing these interventions in low- and middle-income countries.     

Trend in mortality from respiratory distress syndrome in the United States, 1970-1995

OBJECTIVE: We examined the trend in mortality caused by respiratory distress syndrome (RDS) and its impact on changes in infant and neonatal mortality rates (IMR, NMR) in the United States.Study design: Data on infant deaths in the United States for the period 1970 through 1995 were used to compare RDS-specific IMR to other cause-specific IMR. Data from the U.S. birth cohorts of 1985 through 1991 were used to examine birth weight- and RDS-specific NMRs. RESULTS: IMR from RDS declined from 2.6 per 1000 live births in 1970 to 0.4 per 1000 in 1995. More than three quarters of this decline occurred between 1970 and 1985. RDS-specific NMR declined by 13% between 1985 and 1988 and by more than twofold greater, that is, 28%, between 1988 and 1991. There was also a significant reduction in postneonatal mortality from chronic lung diseases between 1988 and 1991. CONCLUSIONS: Most of the reduction in mortality from RDS occurred before the introduction of surfactant therapy. The recent accelerated reduction in mortality from RDS between 1988 and 1991 was temporally associated with widespread use of surfactant therapy and was the single most important factor for reduction in overall NMR in the United States.     

Safety and impact of chlorhexidine antisepsis interventions for improving neonatal health in developing countries

Affordable, efficacious, and safe interventions to prevent infections and improve neonatal survival in low-resource settings are needed. Chlorhexidine is a broad-spectrum antiseptic that has been used extensively for many decades in hospital and other clinical settings. It has also been given as maternal vaginal lavage, full-body newborn skin cleansing, and/or umbilical cord cleansing to prevent infection in neonates. Recent evidence suggests that these chlorhexidine interventions may have significant public health impact on the burden of neonatal infection and mortality in developing countries. This review examines the available data from randomized and nonrandomized studies of chlorhexidine cleansing, with a primary focus on potential uses in low-resource settings. Safety issues related to chlorhexidine use in newborns are reviewed, and future research priorities for chlorhexidine interventions for neonatal health in developing countries are discussed. We conclude that maternal vaginal cleansing combined with newborn skin cleansing could reduce neonatal infections and mortality in hospitals of sub-Saharan Africa, but the individual impact of these interventions must be determined, particularly in community settings. There is evidence for a protective benefit of newborn skin and umbilical cord cleansing with chlorhexidine in the community in south Asia. Effectiveness trials in that region are required to address the feasibility of community-based delivery methods such as incorporating these interventions into clean birth kits or training programs for minimally skilled delivery assistants or family members. Efficacy trials for all chlorhexidine interventions are needed in low-resource settings in Africa, and the benefit of maternal vaginal cleansing beyond that provided by newborn skin cleansing needs to be determined.     

Helping Babies Breathe: Improving Neonatal Resuscitation and Global Neonatal Mortality

Significant progress has been made in reducing global child mortality rates over the past 2 decades, with the improvements in survival primarily occurring among children between 1 month and 5 years of age. As a result, neonatal mortality now accounts for almost half of all deaths in children less than 5 years of age. Helping Babies Breathe is a neonatal resuscitation program developed by the American Academy of Pediatrics for use in low-resource settings and aims to teach basic resuscitation skills to providers who are present at deliveries. Using a train-the-trainer curricular model and low-cost simulator and equipment, Helping Babies Breathe has been implemented in more than 80 countries to train 500 000 providers and has resulted in a marked decline in early neonatal deaths and fresh stillbirths. Ongoing research is being done to optimize strategies to maintain resuscitation skills and knowledge over time, as well as to develop additional methods to improve neonatal resuscitation in low-resource settings, with hopes of achieving the United Nations Sustainable Development Goals for neonatal mortality rates by 2030 worldwide.     

Maintaining normothermia: Why and how?

A high incidence of postnatal hypothermia has been reported in high-as well low-resource countries and it remains an independent predictor of neonatal morbidity and mortality, especially in very preterm infants in all settings. The temperature of newly born infants should be maintained between 36.5 and 37.5 °C after birth through admission and stabilization. Interventions to achieve this may include environmental temperature 23–25 °C, use of radiant warmers, exothermic mattresses, woollen or plastic caps, plastic wraps, humidified and heated gases. Skin-to-skin contact has been used, especially in low-resource settings. The combinations of these interventions applied to quality improvement initiatives, including staff training, use of checklists, and continuous feedback with the staff involved in the management of the neonate, are key factors to prevent heat loss from delivery room to admission to the neonatal intensive care unit. The admission temperature should be recorded as a predictor of outcomes as well as a quality indicator.     

Recommendations for the implementation of Kangaroo Mother Care for low birthweight infants

Good quality care of low birthweight infants could reduce neonatal mortality in low-income countries, but the technologies used in rich countries are inappropriate. Kangaroo Mother Care does not need expensive and sophisticated equipment, and for its simplicity it can be applied almost everywhere, including peripheral maternity units of very low-income countries. Kangaroo Mother Care (KMC) can also contribute to the humanization of neonatal care and to better bonding between mother and baby in both poor and rich countries. A group of health professionals with experience in KMC met in a workshop to discuss its effectiveness, safety, applicability and acceptability in different settings: from first and second level maternity units in settings with very limited resources, to second and third level units in settings with limited resources, to second and third level maternity and neonatal care units in settings with ample resources and infant mortality rates <15/1000. The paper summarizes the recommendations of this group of health professionals for the implementation of KMC in these various settings, together with suggested research priorities.     

Care of infants with gastroschisis in low-resource settings

There is great global disparity in the outcome of infants born with gastroschisis. Mortality approaches 100% in many low income countries. Barriers to better outcomes include lack of antenatal diagnosis, deficient pre-hospital care, ineffective neonatal resuscitation and venous access, limited intensive care facilities, poor access to the operating theatre and safe neonatal anesthesia, and lack of neonatal parenteral nutrition. However, lessons can be learned from the evolution in management of gastroschisis in high-income countries, generic efforts to improve neonatal survival in low- and middle-income countries as well as specific gastroschisis management initiatives in low-resource settings. Micro and meso-level interventions include educational outreach programs, and pre and in hospital management protocols that focus on resuscitation and include the delay or avoidance of early neonatal anesthesia by using a preformed silo or equivalent. Furthermore, multidisciplinary team training, nurse empowerment, and the intentional involvement of mothers in monitoring and care provision may contribute to improving survival. Macro level interventions include the incorporation of ultrasound into World Health Organisation antenatal care guidelines to improve antenatal detection and the establishment of the infrastructure to enable parenteral nutrition provision for neonates in low- and middle-income countries. On a global level, gastroschisis has been suggested as a bellwether condition for evaluating access to and outcomes of neonatal surgical care provision.     

Neonatal surgery in Africa

The management of neonatal surgical problems continues to pose considerable challenges, particularly in low-resource settings. The burden of neonatal surgical diseases in Africa is not well documented. The characteristics of some neonatal surgical problems are highlighted. Late presentation coupled with poor understanding of the milieu interior of the neonates by incompetent health care providers and poorly equipped hospitals combine to give rise to the unacceptable high morbidity and mortality in most parts of Africa. Proper training of all staff involved in neonatal health care coupled with community awareness must be vigorously pursued by all stakeholders. Various governments throughout the continent of Africa, in conjunction with international donor agencies, must not only provide an adequate budget for health care services and improve infrastructures, but must also deliberately encourage and provide funding for neonatal surgical care and research across the continent. The well-established pediatric surgical training programs, particularly in North and South Africa, should hold the moral responsibility of training all possible numbers of young surgeons from other African countries that do not have any existing pediatric surgical training programs or those countries suffering from remarkable shortage of trained pediatric surgeons.     

Optimizing initial neonatal resuscitation to reduce neonatal encephalopathy around the world

One million two hundred thousand neonatal lives are lost each year due to intrapartum-related events; 99% of these deaths occur in low- and lower middle-income countries. Neonates exposed to intrapartum-related events present with failure to breathe at birth. Quick and effective delivery room management of these neonates is critical in the prevention of brain injury. Given the prominent role of lung aeration in the cardiopulmonary transition at birth, the mainstay of neonatal resuscitation is effective ventilation. Basic neonatal resuscitation focuses on simple stimulation, airway positioning and clearing, and bag-mask ventilation. Although principles for basic neonatal resuscitation remain the same for high- and low-resource settings, guidelines may differ based on available human and material resources. Formal training in basic resuscitation reduces intrapartum-related neonatal mortality in low-resource settings. However, there remain opportunities to improve provider performance for increased impact with other strategies such as regular practice and continuous quality improvement.     

Respiratory distress in term neonates in low-resource settings

Most neonatal deaths worldwide occur in low- and middle-income countries (LMICs). Respiratory distress is an important cause of neonatal morbidity and mortality. The epidemiology of respiratory distress among term neonates who constitute the vast majority of births is under reported. The scarcely available data from LMICs suggest an incidence of 1.2% to 7.2% among term live births and greater morbidity compared to that in high-income countries. Pneumonia and meconium aspiration syndrome are the predominant causes among outborn neonates, but next only to transient tachypnea among inborn neonates. Community management of neonatal sepsis/pneumonia using simplified antibiotic regimens when referral is not feasible, implementation of non-invasive ventilation, and innovative low-cost technologies to deliver respiratory therapy are important advances that have taken place in these settings. There is an urgent need to generate data on respiratory morbidities among term neonates so that the limited resources in these settings can be allocated judiciously.     

Regionalized perinatal care in developing countries.

Neonatal-perinatal ill health and mortality are overwhelmingly a burden of the developing world. As many as 90% of births, 98% of fetal deaths and 98% of neonatal deaths occur in less developed countries. Regionalized perinatal services were introduced in developed countries when most neonatal mortality was confined to very-low-birthweight babies who required intensive perinatal care to survive. A large proportion of newborn morbidity and mortality in developing countries, however, continues to occur among full-term and moderate-sized low-birthweight neonates who can be managed well in the community and at small hospitals. The model of regionalized perinatal care as practiced in developed countries is, at present, neither affordable nor relevant to the needs of many developing countries. It is possible to achieve considerably lower neonatal mortality rates in resource-poor settings by implementing home-based newborn care delivered by community health workers, and by promoting institutional perinatal care at simple facilities provided by trained midwives.     

Clinical algorithms for the identification of sick newborns in community-based settings

Clinical algorithms can be powerful tools for the identification of sick newborns at risk of neonatal mortality. Several studies have evaluated clinical signs for newborns aged 0-60 days to identify severe illness; however, few studies have focused specifically on the most vulnerable time period for neonatal death, the first week of life. Therefore, we reviewed the studies that evaluated clinical signs in newborns 0-60 days, focusing on infants 0 to <7 days. Based on a comparison of relevant studies, we then identified the common, important clinical signs shown to be useful for the identification of at-risk newborns by health workers in community-based and low-resource settings. CONCLUSION: We concluded that further work is urgently needed to develop a clinical algorithm for widespread validation in various community-based settings, which focuses specifically on newborns <7 days at risk of early neonatal mortality.     

What will it take to stop the needless deaths of millions of women and children each year?

Each year, almost 10 million children die before their fifth birthday; the majority from easily preventable diseases such as diarrhoea, pneumonia and malaria. Furthermore, 10 million women endure pregnancy‐related morbidities annually while 500,000 die in childbirth. The link between maternal and child health is inextricable and worldwide inequities continue to widen: 99% of all neonatal deaths occur in developing countries, while maternal mortality rates are 1,000 times greater for women in poor countries compared to those living in rich nations. These discrepencies continue to persist despite the presence of a multitude of simple, cost‐effective interventions which could save the lives of millions of women and children worldwide each year for a fraction of the cost associated spent on health care in the developed world.     

Impact of community-based behaviour-change management on perceived neonatal morbidity: a cluster-randomized controlled trial in Shivgarh, Uttar Pradesh, India

In the context of high neonatal mortality rate (NMR) in developing country settings, a promising strategy for enhancing newborn health is promotion of preventive newborn care practices. We measured the effect of a behaviour-change intervention on perceived neonatal illnesses in rural Uttar Pradesh, India. The study was nested in a cluster-randomized controlled trial of the impact of a package of essential newborn care on NMR. We prospectively enrolled 802 mothers and administered a questionnaire on perceived neonatal morbidities. Regression analysis showed that newborns in the intervention clusters had significantly lower risk of perceived diarrhoea [adjusted relative risk (aRR) 0.67, 95% confidence interval (CI) 0.49-0.90] and skin-related complications [aRR 0.67, 95% CI 0.45-1.00] compared to newborns in the comparison area. Assuming incidence of perceived illnesses is a proxy for actual morbidity rates, we conclude that promotion of preventive care practices through behaviour-change interventions was effective in reducing neonatal morbidities.     

Managing severe infection in infancy in resource poor settings

Reducing childhood mortality in resource-poor regions depends on effective interventions to decrease neonatal mortality from severe infection, which contributes up to a half of all neonatal deaths. There are key differences in resource-poor, compared to resource-rich, countries in terms of diagnosis, supportive care and treatment. In resource-poor settings, diagnosis is based on identifying clinical syndromes from international guidelines; microbiological investigations are restricted to a few research facilities. Low levels of staffing and equipment limit the provision of basic supportive care, and most facilities cannot provide respiratory support. Empiric antibiotic treatment guidelines are based on few aetiological and antimicrobial susceptibility data. Research on improving health care systems to provide effective supportive care, and implementation of simple pragmatic interventions, such as low-cost respiratory support, are essential, together with improved surveillance to monitor emerging drug resistance and treatment failures. Reductions in mortality will also be achieved through prevention of infection; including emerging vaccination and anti-sepsis strategies.     

Use of CPAP and Surfactant Therapy in Newborns with Respiratory Distress Syndrome

Respiratory distress syndrome (RDS) is a major disease burden in the developing countries. Current evidence supports early continuous positive airway pressure (CPAP) use and early selective surfactant administration as the most efficacious interventions in the management of RDS, both in developed and developing countries. In developing countries, it is recommended to increase institutional deliveries and increase the coverage of antenatal steroids in women in preterm labor as preventive measures. Establishing intervention of CPAP and surfactant therapies in the Level II special care newborn units (SCNUs) and Level III units requires focus on training nursing staff and pediatricians across the board. These approaches would pave the way in optimizing the care of the preterm infants with RDS and decrease their mortality and morbidity significantly.     

Discordance between male and female deaths due to the respiratory distress syndrome

General neonatal mortality statistics and those for the respiratory distress syndrome (RDS) were examined for the State of Wisconsin from 1979 through 1982. The objectives were to ascertain whether there are differences in total neonatal mortality related to sex and birth weight, to determine the veracity of reported gender differences in deaths due to RDS, and to assess the contribution of other risk factors for neonatal mortality to overall and sex-specific deaths occurring secondary to RDS. Additionally, a prospective analysis was performed at one perinatal center during a 5-year period in attempts to determine whether gender remained a significant factor in deaths due to RDS after adjusting for incidence. Overall, the most frequent diagnoses in those who died were RDS (15.6%), deaths due to complications of pregnancy (8%), immaturity (4.2%), and asphyxia (3.4%). The majority of fatalities for both sexes occur in neonates weighing less than 1 kg and the percentage of deaths attributable to RDS is greatest between 1 and 1.5 kg. The difference between sexes is also maximal in the latter weight group. Deaths secondary to RDS are greater for males regardless of Apgar score at one and five minutes, mode of delivery, maternal age, or ancillary diagnosis. These data suggest that deaths secondary to RDS are consistently greater in male neonates and that delivery within a limited "window" of time during gestation increases male susceptibility to fatal RDS.     

Community health and medical provision: impact on neonates (the CHAMPION trial)

Background  

The trial aims to evaluate whether neonatal mortality can be reduced through systemic changes to the provision and promotion of healthcare. Neonatal mortality rates in India are high compared to other low income countries, and there is a wide variation of rates across regions. There is evidence that relatively inexpensive interventions may be able to prevent up to 75% of these deaths. One area with a particularly high rate is Mahabubnagar District in Andhra Pradesh, where neonatal mortality is estimated to be in the region of 4–9%. The area suffers from a vicious cycle of both poor supply of and small demand for health care services. The trial will assess whether a package of interventions to facilitate systemic changes to the provision and promotion of healthcare may be able to substantially reduce neonatal mortality in this area and be cost-effective. If successful, the trial is designed so that it should be possible to substantially scale up the project in regions with similarly high neonatal mortality throughout Andhra Pradesh and elsewhere.     

Trends in perinatal, neonatal and post-neonatal mortality in Austria and Tyrol, with special reference to 1979-1988]

Analysis of neonatal, perinatal and infant mortality rates is a useful basis to compare the quality of neonatal care in a country. During the last decades these parameters have been falling steadily in Austria as well as in other industrialized countries. Regarding the various provinces of Austria substantial regional differences occur. Apparently the decline in mortality rates is not only contributable to medical progress but as strongly influenced by social and economic changes. In the mid-seventies absolute and relative neonatal mortality rates in Austria definitely decreased, most probably attributable to the installation of neonatal intensive care units. During 1968-1978 the decrease in neonatal mortality was mainly due to reduced first-day-mortality, whereas during the following decade it was mainly due to reduced mortality of the 2nd until 7th day of life. Interestingly, the rate of preterm infants in Austria remained virtually constant during 1968-1988 despite improved pre- and perinatal care. Paralleling the development in full-term neonates the peri-/neo- and postneonatal mortality rates of preterm infants decreased. Predictably - as in other countries - the highest improvement was found in the low birth weight groups Nevertheless, premature births have accounted for the majority of neonatal and perinatal deaths.     

Cracking the whip on childhood mortality--role of the specialized neonatal unit in Eritrea.

Health care services in developing countries are being challenged by high childhood mortality rates. Although there have been tremendous strides made in reducing infant mortality rates largely due to vaccinations and improved standards of living, a lot remains to be done to reduce neonatal mortality. Achievement of the Millennium Development Goal (MDG) number 4 on childhood mortality will remain unattainable in most developing countries unless purpose based interventions targeted at reducing neonatal mortality are instituted. This viewpoint is based on the experiences gained in Eritrea, a country that gained independence less than twenty years ago following a protracted war that left a trail of destruction of infrastructure in general and health facilities in particular. War that broke out with Ethiopia less than 10 years into its independence and border conflicts followed by a no peace no war stalemate situation aggravated by frequent droughts have continued to throttle economic recovery, reconstruction and rehabilitative efforts. The population is estimated at 3.5 million comprising of nine ethnic groups who speak different languages. The country has a surface area of 124,000 km2 which shares borders with Sudan, Ethiopia, Djibouti and the Red Sea. CONCLUSION: Attainment of the MDG number 4 on reduction of childhood mortality can be achieved by addressing morbidities of the neonate where the bottle neck currently appears to be sited.
