Beyond Newborn Resuscitation: Essential Care for Every Baby and Small Babies.

Helping Babies Breathe (HBB) addresses a major cause of newborn mortality by teaching basic steps of neonatal resuscitation and improving survival rates of infants affected by intrapartum-related events or asphyxia. Addressing the additional top causes of mortality (infection and prematurity) requires more comprehensive education, including content on thermal and nutritional support, breastfeeding, and alternative feeding strategies, as well as recognition and treatment of infection. Essential Care for Every Baby (ECEB) and Essential Care for Small Babies (ECSB) use educational principles developed with HBB as a model for teaching basic newborn care. These programs complement the content provided with HBB, further integrate counseling of families, and advance the agenda of providing quality care to all infants at birth. ECEB and ECSB have further demonstrated that engagement of individuals through active participation in their education empowers providers at all levels. With added experience teaching and implementing ECEB and ECSB, the next generation of newborn educational programs will likely incorporate bedside teaching and clinical exposure, multimedia platforms for demonstrating clinical content, and added efforts toward quality improvement. Through ECEB and ECSB, the attention brought to the newborn health agenda with HBB has only grown. Although current global health issues pose new challenges in implementing this agenda, these programs together provide a critical framework to both educate and advocate for optimal care of every newborn.

Development and Impact of Helping Babies Breathe Educational Methodology.

The educational pedagogy surrounding Helping Babies Breathe (HBB) has been transformative in going beyond a curriculum focused only on basic neonatal resuscitation; indeed, it created the framework for an educational program that has served as a model for replication for other impactful programs, such as the Helping Mothers Survive and other Helping Babies Survive curricula. The tenets of HBB include incorporation of innovative learning strategies such as small group discussion, skills-based learning, simulation and debriefing, and peer-to-peer learning, all of which begin the hard work of changing behaviors that may eventually affect health care systems. Allowing for adaptation for local resources and culture, HBB has catalyzed innovation in the development of simplified, pictorial educational materials, in addition to low-tech yet realistic simulators and adjunct devices that have played an important role in empowering health care professionals in their care of newborns, thereby improving outcomes. In this review, we describe the development of HBB as an educational program, the importance of field testing and input from multiple stakeholders including frontline workers, the strategies behind the components of educational materials, and the impact of its pedagogy on learning.

Effect of Fentanyl Boluses on Cerebral Oxygenation and Hemodynamics in Preterm Infants: A Prospective Observational Study.

BACKGROUND: Fentanyl is a commonly used off-label medication for pain control and sedation in preterm infants. Yet, the effect of fentanyl on cerebral hemodynamics in preterm neonates remains unexplored. OBJECTIVE: To evaluate the effect of a bolus dose of fentanyl on the regional cerebral oxygen saturation (RcSO2), cerebral fractional tissue oxygen extraction (cFTOE) and left ventricular output (LVO) as compared with pre-administration baseline in preterm infants. METHODS: This was a prospective observational study conducted in a level III Canadian NICU from September 2017 to February 2019. Preterm infants born <37 weeks of gestation and scheduled to receive a fentanyl bolus (1-2 µg/kg/dose) were eligible. Infants with major congenital anomalies, medically unstable and those who had received fentanyl in the previous 48 h were excluded. OUTCOMES: The primary outcome was the difference between RcSO2 measured 5 min prior to and RcSO2 measured at defined time points after administration of fentanyl. RESULTS: Twenty-eight infants were enrolled during the study period (median gestational age 28 weeks; interquartile range [IQR] 25-29 weeks; median birth weight 1,035 g [IQR 830-1,292 g]; median age 4 days [IQR 3-7 days]). Mean (±standard deviation) baseline RcSO2 was 73.6% (±11.8), cFTOE was 21.9 (±11.2) and LVO was 380 (±147) mL/kg/min prior to fentanyl infusion. One-way ANOVA showed no statistically significant difference between baseline and any of the post-fentanyl cerebral oxygenation, tissue oxygen extraction or cardiac output measures (p > 0.05). CONCLUSION: Administration of fentanyl bolus for procedural pain and sedation was not shown to significantly affect cerebral oxygenation, cerebral tissue oxygen extraction or cardiac output in stable preterm infants.

Outcomes and care practices for preterm infants born at less than 33 weeks' gestation: a quality-improvement study.

BACKGROUND: Preterm birth is the leading cause of morbidity and mortality in children younger than 5 years. We report the changes in neonatal outcomes and care practices among very preterm infants in Canada over 14 years within a national, collaborative, continuous quality-improvement program. METHODS: We retrospectively studied infants born at 23-32 weeks' gestation who were admitted to tertiary neonatal intensive care units that participated in the Evidence-based Practice for Improving Quality program in the Canadian Neonatal Network from 2004 to 2017. The primary outcome was survival without major morbidity during the initial hospital admission. We quantified changes using process-control charts in 6-month intervals to identify special-cause variations, adjusted regression models for yearly changes, and interrupted time series analyses. RESULTS: The final study population included 50 831 infants. As a result of practice changes, survival without major morbidity increased significantly (56.6% [669/1183] to 70.9% [1424/2009]; adjusted odds ratio [OR] 1.08, 95% confidence interval [CI] 1.06-1.10, per year) across all gestational ages. Survival of infants born at 23-25 weeks' gestation increased (70.8% [97/137] to 74.5% [219/294]; adjusted OR 1.03, 95% CI 1.02-1.05, per year). Changes in care practices included increased use of antenatal steroids (83.6% [904/1081] to 88.1% [1747/1983]), increased rates of normothermia at admission (44.8% [520/1160] to 67.5% [1316/1951]) and reduced use of pulmonary surfactant (52.8% [625/1183] to 42.7% [857/2009]). INTERPRETATION: Network-wide quality-improvement activities that include better implementation of optimal care practices can yield sustained improvement in survival without morbidity in very preterm infants.

SNAP-II for prediction of mortality and morbidity in extremely preterm infants.

OBJECTIVE: To determine the specific Score of Neonatal Acute Physiology (SNAP-II) cut-off scores associated with outcomes in extremely preterm infants, and to examine its contribution to predictive models that include nonmodifiable birth predictors. STUDY DESIGN: Retrospective observational study of 9240 infants born at 22-28 weeks' gestation and admitted to the Canadian Neonatal Network from 2010 to 2015. Outcomes included early and hospital mortality, composite of mortality/morbidity and individual morbidities. The SNAP-II cut-off to predict each outcome was determined using the Youden index. Additional contributions were evaluated using a base model that adjusted for gestational age, birth weight z-score and sex and by comparing the area under the curve (AUC). RESULTS: The mortality/morbidity rate was 63% (5859/9240). Specific SNAP-II cut-offs ranged from 12 to 20 and were associated with each adverse outcome. Adding SNAP-II cut-offs to predictive models that included birth variables significantly improved (p < .05) the prediction of early mortality (AUC 0.84 versus 0.79), hospital mortality (AUC 0.80 versus 0.78), mortality/morbidity (AUC 0.76 versus 0.75), and severe neurological injury (AUC 0.69 versus 0.66) but had little or no effect on predictive models for retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, and nosocomial infection. CONCLUSIONS: SNAP-II cut-offs were independently associated with each adverse outcome and using the proposed SNAP-II cut-offs improved the performance of predictive models for certain short-term outcomes.

Automated versus manual control of inspired oxygen to target oxygen saturation in preterm infants: a systematic review and meta-analysis.

OBJECTIVES: To conduct a systematic review of clinical trials comparing automated versus manual fraction of inspired oxygen (FiO2) control to target oxygen saturation (SpO2) in preterm infants. DESIGN: The authors searched MEDLINE, Embase, CENTRAL, and CINAHL from inception upto December 2016, reviewed conference proceedings and sought results of unpublished trials. Studies were included if automated FiO2 control was compared to manual control in preterm infants on positive pressure respiratory support. The primary outcome was percentage of time spent within the target SpO2 range. Summary mean differences (MD) were computed using random effects model. RESULTS: Out of 276 identified studies 10 met the inclusion criteria. Automated FiO2 control significantly improved time being spent within the target SpO2 range [MD: 12.8%; 95% CI: 6.5-19.2%; I2 = 90%]. Periods of hyperoxia (MD:-8.8%; 95% CI: -15 to -2.7%), severe hypoxia(SpO2 < 80%)(MD: -0.9%;95%CI: -1.5 to -0.4%) and hypoxic events (MD: -5.6%; 95% CI: -9.1 to -2.1%) were significantly reduced with automated control. CONCLUSION: Automated FiO2 adjustment provides significant improvement of time in target saturations, reduces periods of hyperoxia, and severe hypoxia in preterm infants on positive pressure respiratory support.

Association of early caffeine administration and neonatal outcomes in very preterm neonates.

IMPORTANCE: Advantages of caffeine for apnea of prematurity have prompted clinicians to use it prophylactically even before apnea. OBJECTIVE: To determine the effect of early initiation of caffeine therapy on neonatal outcomes in very preterm infants born in Canada. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted. Patients included preterm neonates born at less than 31 weeks' gestation admitted to 29 participating Canadian Neonatal Network neonatal intensive care units between January 1, 2010, and December 31, 2012. EXPOSURES: Neonates who received caffeine were divided into 2 groups based on the following timing of caffeine initiation: within the first 2 days after birth (early) and on or after the third day following birth (late). MAIN OUTCOME AND MEASURE: A composite of death or bronchopulmonary dysplasia. RESULTS: Of 5517 eligible neonates, 5101 (92.5%) received caffeine (early: 3806 [74.6%]; late: 1295 [25.4%]). There was no difference in weight or gestational age at birth between the groups. Neonates in the early group had decreased odds of a composite outcome of death or bronchopulmonary dysplasia (adjusted odds ratio [AOR], 0.81; 95% CI, 0.67-0.98) and patent ductus arteriosus (AOR, 0.74; 95% CI, 0.62-0.89). There was no difference between the groups in mortality (AOR, 0.98; 95% CI, 0.70-1.37), necrotizing enterocolitis (AOR, 0.88; 95% CI, 0.65-1.20), severe neurological injury (AOR, 0.80; 95% CI, 0.63-1.01), or severe retinopathy of prematurity (AOR, 0.78; 95% CI, 0.56-1.10). CONCLUSIONS AND RELEVANCE: In very preterm neonates, early (prophylactic) caffeine use was associated with a reduction in the rates of death or bronchopulmonary dysplasia and patent ductus arteriosus. No adverse impact on any other outcomes was observed.

Gentamicin in neonates at risk for sepsis - peak serum concentrations are not necessary.

BACKGROUND: Serum gentamicin concentrations (GSCs) are frequently obtained before and after gentamicin administration to newborns with, or at high risk for, sepsis. OBJECTIVE: To determine whether performing a peak GSC assay when the trough GSC is within the guidelines for care would add clinically relevant information for health care workers. METHODS: A retrospective review of the IWK Health Centre (Halifax, Nova Scotia) laboratory database for peak and trough GSC for infants <28 days after birth was performed. RESULTS: Of 5253 paired samples of trough and peak GSCs, 3001 (57%) had trough GSCs ≤2 µg/mL. Of these, only nine (0.3%) had a peak GSC >10 µg/mL. CONCLUSIONS: Performing a peak GSC measurement does not provide further clinically important data and increases patient morbidity and hospital costs.

HISTORIQUE: On vérifie souvent les concentrations de gentamicine sérique avant et après l'administration de gentamicine aux nouveau-nés présentant une septicémie ou qui y sont très vulnérables. OBJECTIF: Déterminer si l'obtention de la valeur de pointe de la concentration de gentamicine sérique (CGS) lorsque la valeur seuil respecte les lignes directrices de soins ajoute de l'information pertinente sur le plan clinique pour les travailleurs de la santé. MÉTHODOLOGIE: Analyse rétrospective de la base de données du laboratoire de l'IWK Health Centre à l'égard des valeurs de pointe et des valeurs seuils du CGS obtenues chez des bébés de moins de 28 jours de vie. RÉSULTATS: Des 5 253 échantillons appariés, 3 001 (57 %) avaient une valeur seuil de la CGS égale ou inférieure à 2 µg/mL. De ce nombre, seulement neuf (0,3 %) avaient une valeur de pointe de la CGS supérieure à 10 µg/mL. CONCLUSIONS: L'obtention de la valeur de pointe de la CGS ne fournit pas de nouvelles données importantes sur le plan clinique, sans compter qu'elle accroît la morbidité des patients et les coûts pour l'hôpital.

Reflections on knowledge translation in Canadian NICUs using the EPIQ method.

The Canadian Neonatal Network conducted a trial of Evidence-Based Practice for Improving Quality (EPIQ) between 2002 and 2005. Improved neonatal intensive care unit (NICU) outcomes established credibility for quality improvement. We surveyed team members and physician leaders to examine critical success factors and barriers to improvement during EPIQ. Respondents agreed that EPIQ had a high utility, was effectively implemented and was a major learning opportunity. The collaborative nature of the project was key to success. Respondents identified the need for additional training and resources in quality improvement. Better communication between clinicians and senior leaders is required to support quality improvement in NICUs.

A multicenter study on the clinical outcome of chorioamnionitis in preterm infants.

OBJECTIVE: The purpose of this study was to examine the effects of clinical maternal chorioamnionitis on morbidity and mortality rates among infants who are at < 33 weeks of gestation, adjusted for patient characteristics that included admission neonatal illness severity (Score for Neonatal Acute Physiology, version II; SNAP-II). STUDY DESIGN: With multivariate logistic regression analysis, prospectively collected hospital outcomes from the Canadian Neonatal Network of singleton infants with birth gestational age of < 33 weeks and clinical chorioamnionitis were compared retrospectively with nonexposed infants. RESULTS: Of 3094 infants, 477 infants (15.4%) who were exposed to clinical chorioamnionitis had significantly higher admission SNAP-II scores. Bivariate analysis revealed that the neonatal mortality rate was increased significantly in the chorioamnionitis group (10.6% vs 6.1%). Multivariate regression analysis with adjustment for illness severity indicated that chorioamnionitis was associated with an increased risk of early sepsis (odds ratio, 5.54; 95% confidence interval, 2.87-10.69) and severe intraventricular hemorrhage (odds ratio, 1.62; 95% confidence interval, 1.17-2.24) but not neonatal death. CONCLUSION: Preterm infants who are exposed to clinical chorioamnionitis have an increased risk of early-onset sepsis and severe intraventricular hemorrhage.

Research priorities to reduce global mortality from newborn infections by 2015.

BACKGROUND: Newborn infections are responsible for approximately one-third of the estimated 4.0 million neonatal deaths that occur globally every year. Appropriately targeted research is required to guide investment in effective interventions, especially in low resource settings. Setting global priorities for research to address neonatal infections is essential and urgent. METHODS: The Department of Child and Adolescent Health and Development of the World Health Organization (WHO/CAH) applied the Child Health and Nutrition Research Initiative (CHNRI) priority-setting methodology to identify and stimulate research most likely to reduce global newborn infection-related mortality by 2015. Technical experts were invited by WHO/CAH to systematically list and then use standard methods to score research questions according to their likelihood to (i) be answered in an ethical way, (ii) lead to (or improve) effective interventions, (iii) be deliverable, affordable, and sustainable, (iv) maximize death burden reduction, and (v) have an equitable effect in the population. The scores were then weighted according to the values provided by a wide group of stakeholders from the global research priority-setting network. FINDINGS: On a 100-point scale, the final priority scores for 69 research questions ranged from 39 to 83. Most of the 15 research questions that received the highest scores were in the domain of health systems and policy research to address barriers affecting existing cost-effective interventions. The priority questions focused on promotion of home care practices to prevent newborn infections and approaches to increase coverage and quality of management of newborn infections in health facilities as well as in the community. While community-based intervention research is receiving some current investment, rigorous evaluation and cost analysis is almost entirely lacking for research on facility-based interventions and quality improvement. INTERPRETATION: Given the lack of progress in improving newborn survival despite the existence of effective interventions, it is not surprising that of the top ranked research priorities in this article the majority are in the domain of health systems and policy research. We urge funding agencies and investigators to invest in these research priorities to accelerate reduction of neonatal deaths, particularly those due to infections.

Prior leg massage decreases pain responses to heel stick in preterm babies.

AIM: Leg massage could inhibit the transmission of pain by 'closing the gate' or by activating the endogenous opioid pathway to decrease nociceptive transmission of pain associated with heel stick. The aim of this study is to determine the effects of massage therapy prior to heel stick on responses assessed by the Neonatal Infant Pain Scale (NIPS) (primary outcome), heart rate, respiratory rate and oxygen saturation (secondary outcomes) in infants who required a heel stick for blood sampling. METHODS: This randomised, double-blind, crossover trial with infants from 1 to 7 days post birth excluded those with prior surgery, septicaemia, current assisted ventilation or an analgesic within 48 h. After informed consent, 13 infants received a 2-min massage of the ipsilateral leg prior to heel stick on the first study sampling and no massage on the next sampling 2-7 days later and 10 infants had the reverse order. The bedside nurse, blinded to the intervention, measured NIPS, heart rate, respiratory rate, and oxygen saturation prior to massage, after massage, and 5 min after heel stick. Serum cortisol was measured with the blood sampling. RESULTS: In 23 infants (birthweight 795-2507 g), there were no adverse physiologic effects of massage. After heel stick, NIPS (P < 0.001) and heart rate (P = 0.03) were increased in the no-massage group compared with the massage group. Respiratory rate, oxygen saturation and serum cortisol were not significantly different. CONCLUSION: Gentle massage of the leg prior to heel stick is safe and decreases pain responses in preterm infants.

Variations in rates of nosocomial infection among Canadian neonatal intensive care units may be practice-related.

BACKGROUND: Nosocomial infection (NI), particularly with positive blood or cerebrospinal fluid bacterial cultures, is a major cause of morbidity in neonatal intensive care units (NICUs). Rates of NI appear to vary substantially between NICUs. The aim of this study was to determine risk factors for NI, as well as the risk-adjusted variations in NI rates among Canadian NICUs. METHODS: From January 1996 to October 1997, data on demographics, intervention, illness severity and NI rates were submitted from 17 Canadian NICUs. Infants admitted at < 4 days of age were included. NI was defined as a positive blood or cerebrospinal fluid culture after > 48 hrs in hospital. RESULTS: 765 (23.5%) of 3253 infants < 1500 g and 328 (2.5%) of 13228 infants > or = 1500 g developed at least one episode of NI. Over 95% of episodes were due to nosocomial bacteremia. Major morbidity was more common amongst those with NI versus those without. Mortality was more strongly associated with NI versus those without for infants > or = 1500 g, but not for infants < 1500 g. Multiple logistic regression analysis showed that for infants < 1500 g, risk factors for NI included gestation < 29 weeks, outborn status, increased acuity on day 1, mechanical ventilation and parenteral nutrition. When NICUs were compared for babies < 1500 g, the odds ratios for NI ranged from 0.2 (95% confidence interval [CI] 0.1 to 0.4) to 8.6 (95% CI 4.1 to 18.2) when compared to a reference site. This trend persisted after adjustment for risk factors, and was also found in larger babies. CONCLUSION: Rates of nosocomial infection in Canadian NICUs vary considerably, even after adjustment for known risk factors. The implication is that this variation is due to differences in clinical practices and therefore may be amenable to interventions that alter practice.

Canadian Paediatric Surveillance Program confirms low incidence of hemorrhagic disease of the newborn in Canada.

OBJECTIVES: To determine the incidence of hemorrhagic disease of the newborn (HDNB) in Canada and its relationship to the administration of vitamin K(1) (hereafter referred to as vitamin K) following birth. METHODS: The Canadian Paediatric Surveillance Program sent monthly surveys to over 2100 Canadian paediatricians requesting identification of infants with defined criteria for HDNB. Reports were confirmed with subsequent case-specific data, including coagulation test results. RESULTS: Of the 26 reports (10 in 1997, eight in 1998, four in 1999, four in 2000), two were from before the start of the study, three were duplicate reports, four cases erroneously identified hemolytic disease of the newborn, three had coagulation studies which were normal or not done, and seven had other disorders with bleeding. Of the six confirmed cases of infants with HDNB (one classic, five late), all had intracranial bleeding and five suffered neurological sequelae. The estimated incidence of HDNB in Canada (including infants who had oral vitamin K prophylaxis or did not receive vitamin K) is approximately 0.45/100,000. CONCLUSION: This study confirmed the relatively low incidence of HDNB in Canada and validated the Canadian Paediatric Society's recommendation that all newborns should be given intramuscular vitamin K shortly following birth. To alleviate confusion with haemolytic disease of the newborn, Britain and Australia modified the title of their subsequent HDNB study to vitamin K deficiency bleeding.

The benefit of preterm birth at tertiary care centers is related to gestational age.

OBJECTIVE: The purpose of this study was to examine the relationship between gestational age and outcomes of outborn versus inborn preterm infants. STUDY DESIGN: Multivariable logistic regression analysis was used to examine gestational age-specific, risk-adjusted outcomes of 2962 singleton infants who were born at <32 weeks of gestation who were admitted to 17 Canadian neonatal intensive care units from 1996 through 1997. RESULTS: The risk-adjusted incidence was significantly (P <.05) higher among outborn versus inborn infants for mortality rates (odds ratio, 2.2) and > or =grade 3 intraventricular hemorrhage (odds ratio, 2.1) at < or =26 weeks of gestation and for chronic lung disease (odds ratio, 1.7) at 27 to 29 weeks of gestation. Outcomes of outborn and inborn infants at 30 to 31 weeks of gestation were not significantly different. CONCLUSION: The short-term benefit of preterm birth at tertiary centers is related inversely to gestational age and may not extend beyond 29 weeks of gestation.

Variations in central venous catheter-related infection risks among Canadian neonatal intensive care units.

BACKGROUND: The objective of this study was to examine central venous catheter (CVC)-related nosocomial blood stream infection risks of umbilical venous, percutaneous and Broviac catheters, as well as variations in CVC use and CVC-related risk for nosocomial blood stream infection in the neonatal intensive care unit (NICU). METHODS: A cohort study was performed based on 19,507 infants admitted to 17 NICUs in the Canadian Neonatal Network from January, 1996, through October, 1997. Information on these subjects was prospectively collected by trained abstractors. Incidence of infection was measured as infection episodes per 1000 patient days. The risk ratio (RR) of CVC use for nosocomial blood stream infection was calculated as the infection rate during catheter days divided by the infection rate during noncatheter days. Using a Poisson regression model we examined the adjusted RR of CVC use for nosocomial blood stream infection, controlling for patient characteristics and illness severity at admission. Interinstitutional variations in CVC-related infection risks were examined by stratified analyses. RESULTS: CVC were used in 22.5% of patients. The incidence of nosocomial blood stream infection was 2.9 per 1000 noncatheter days, 7.2 per 1000 umbilical venous catheter days, 13.1 per 1000 percutaneous catheter days and 12.1 per 1000 Broviac catheter days. The RR for nosocomial blood stream infection, adjusted for differences in patient characteristics and admission illness severity, was 2.5 for umbilical venous catheter, 4.6 for percutaneous catheter and 4.3 for Broviac catheter (P < 0.05). There were significant (P < 0.05) risk-adjusted variations in CVC-related infection risks among NICUs. CONCLUSIONS: CVC use increased the risk of nosocomial blood stream infection. The risk of nosocomial blood stream infection in percutaneous and Broviac catheters was 70 to 80% higher than in umbilical venous catheters. There was significant variation in CVC-related infection risks among Canadian NICUs.

Arginine supplementation prevents necrotizing enterocolitis in the premature infant.

OBJECTIVES: To determine whether supplementation with L -arginine reduces the incidence of all stages of necrotizing enterocolitis (NEC) in premature infants with birth weight < or =1250 g and gestational age < or =32 weeks. STUDY DESIGN: In a randomized, double-blind, placebo-controlled study, 152 premature infants were prospectively, randomly assigned to receive either supplemental L -arginine (1.5 mmol/kg per day; n =75 [group A]) or placebo (control group; n = 77 [group B]) with oral feeds/parenteral nutrition during the first 28 days of life. Nutrient intake, plasma ammonia, arginine, and amino acid concentrations were measured in all infants at days 3, 14, and 28 and at the time of diagnosis of NEC. RESULTS: NEC developed in 5 infants in group A compared with 21 infants in group B (P <.001). Arginine intake and plasma arginine concentrations were similar in both groups at study entry and (as expected) increased in group A at days 14 and 28. Plasma arginine concentrations were lower in both groups at time of diagnosis of NEC. No significant differences in maternal and neonatal demographics, nutrient intake, plasma ammonia and total and essential amino acid concentrations were present between the two groups. CONCLUSIONS: Arginine supplementation (1.5 mmol/kg per day) in premature infants reduces the incidence of all stages of NEC.
