RESUMO

OBJECTIVE: To derive testing and treatment thresholds for early-onset neonatal sepsis and compare them to thresholds used in the Kaiser-Permanente (KP) Sepsis Calculator. METHODS: Using surveys distributed in the United States, Brazil and Italy, decision thresholds were derived via self-identified thresholds selected from structured lists (Method 1), and based on clinical vignette responses for testing and treatment with or without inclusion of associated relative risk (Methods 2 and 3). RESULTS: Using Method 1, both testing and treatment thresholds were higher than the KP calculator thresholds. Test thresholds were lower (Method 2) or equivalent (Method 3) to KP using clinical vignettes. No vignette reached the 50% cutoff necessary to define a treatment threshold. CONCLUSION: The test threshold used by the KP calculator is the same as the threshold chosen by clinicians given a vignette and risk estimate. The KP treatment threshold is lower than that derived using all 3 methods.

RESUMO

BACKGROUND: It is challenging to decrease neonatal mortality in middle-income countries, where perinatal asphyxia is an important cause of death. This study aims to analyze the annual trend of neonatal mortality with perinatal asphyxia according to gestational age in São Paulo State, Brazil, during a 10-year period and to verify demographic, maternal and neonatal characteristics associated with these deaths. METHODS: Population-based study of neonatal deaths associated with perinatal asphyxia from 0 to 27 days in São Paulo State, Brazil, from 2004 to 2013. Perinatal asphyxia was considered as associated to death if intrauterine hypoxia, birth asphyxia or neonatal aspiration of meconium were noted in any line of the Death Certificate according to ICD-10. Poisson Regression was applied to analyze the annual trend of neonatal mortality rate according to gestational age. Kaplan-Meier curve was used to assess age at death during the 10-year study period. Hazard ratio of death during the neonatal period according to gestational age was analyzed by Cox regression adjusted by year of birth and selected epidemiological factors. RESULTS: Among 74,002 infant deaths in São Paulo State, 6648 (9%) neonatal deaths with perinatal asphyxia were studied. Neonatal mortality rate with perinatal asphyxia fell from 1.38‰ in 2004 to 0.95‰ in 2013 (p = 0.002). Reduction started in 2008 for neonates with 32-41 weeks, in 2009 for 28-31 weeks, and in 2011 for 22-27 weeks. Median time until 50% of deaths occurred was 25.3 h (95%CI: 24.0; 27.2). Variables independently associated with higher risk of death were < 7 prenatal visits, 1st minute Apgar score 0-3, and death at the same place of birth. Cesarean delivery compared to vaginal was protective against death with perinatal asphyxia for infants at 28-36 weeks. CONCLUSIONS: There was an expressive reduction in neonatal mortality rates associated with perinatal asphyxia during this 10-year period in São Paulo State, Brazil. Variables associated with these deaths highlight the need of public health policies to improve quality of regionalized perinatal care.

RESUMO

BACKGROUND: Population-based studies analyzing neonatal deaths in middle-income countries may contribute to design interventions to achieve the Sustainable Development Goals, established by United Nations. This study goal is to analyze the annual trend of neonatal mortality in São Paulo State, Brazil, over a 10-year period and its underlying causes and to identify maternal and neonatal characteristics at birth associated with neonatal mortality. METHOD: A population-based study of births and deaths from 0 to 27 days between 2004 and 2013 in São Paulo State, Brazil, was performed. The annual trend of neonatal mortality rate according to gestational age was analyzed by Poisson or by Negative Binomial Regression models. Basic causes of neonatal death were classified according to ICD-10. Association of maternal demographic variables (block 1), prenatal and delivery care variables (block 2), and neonatal characteristics at birth (block 3) with neonatal mortality was evaluated by Poisson regression analysis adjusted by year of birth. RESULTS: Among 6,056,883 live births in São Paulo State during the study period, 48,309 died from 0 to 27 days (neonatal mortality rate: 8.0/1,000 live births). For the whole group and for infants with gestational age 22-27, 28-31, 32-36, 37-41 and ≥ 42 weeks, reduction of neonatal mortality rate was, respectively, 18 %, 15 %, 38 %, 53 %, 31 %, and 58 %. Median time until 50 % of deaths occurred was 3 days. Main basic causes of death were respiratory disorders (25 %), malformations (20 %), infections (17 %), and perinatal asphyxia (7 %). Variables independently associated with neonatal deaths were maternal schooling, prenatal care, parity, newborn sex, 1st minute Apgar, and malformations. Cesarean delivery, compared to vaginal, was protective against neonatal mortality for infants at 22-31 weeks, but it was a risk factor for those with 32-41 weeks. CONCLUSIONS: Despite the significant decrease in neonatal mortality rate over the 10-year period in São Paulo State, improved access to qualified health care is needed in order to avoid preventable neonatal deaths and increase survival of infants that need more complex levels of assistance.

RESUMO

Abstract Objective: Evaluate the association between perinatal factors and amplitude-integrated electroencephalogram abnormalities in preterm infants on the first day of life. Methods: This was a cross-sectional study of 60 infants with gestational age between 23 and 32 weeks, without malformations. Infants were continuously monitored by amplitude-integrated electroencephalogram on the first day of life, for at least 3 h. The tracings were recorded and analyzed in each column for the following: burst-suppression pattern, sleep-wake cycle, and amplitude of the lower margin (<3 µV or <5 µV). The association of maternal complications, mode of delivery, birth weight, gestational age, neonatal sex, resuscitation procedures, hypothermia on admission, and the Score for Neonatal Acute Physiology, Perinatal Extension, Version II [SNAPPE-II]) with amplitude-integrated electroencephalogram alterations was assessed by multiple logistic regression. Results: A discontinuous pattern occurred in 65% of infants, and a continuous pattern occurred in 23%. The burst-suppression pattern was associated with vaginal delivery (OR: 7.6; 95% CI: 1.1-53.1) and SNAPPE-II ≥ 40 (OR: 13.1; 95% CI: 1.8-95.1). A lower margin of the amplitude-integrated electroencephalogram of <3 µV was also associated with SNAPPE-II ≥ 40 (OR: 10.6, 95% CI: 2.3-49.2), while a value <5 µV was associated with lower GA (OR: 0.51, 95% CI: 0.34-0.76). There were no associations between the perinatal variables and the absence of a sleep-wake cycle in amplitude-integrated electroencephalogram recordings on the first day of life. Conclusion: Biological variables and clinical severity are associated with electroencephalographic characteristics of preterm infants on the first day of life and should be considered in clinical practice when amplitude-integrated electroencephalogram is performed.


Resumo Objetivo: Avaliar a associação entre fatores perinatais e anormalidades no eletroencefalograma de amplitude integrada em recém-nascidos prematuros no primeiro dia de vida. Métodos: Este é um estudo transversal de 60 bebês com idade gestacional entre 23-32 semanas, sem malformações. Os recém-nascidos foram continuamente monitorados por eletroencefalograma de amplitude integrada no primeiro dia de vida por pelo menos 3 horas. Os traçados foram registrados e analisados em cada coluna para: padrão de surto-supressão, ciclo de sono-vigília e amplitude da margem inferior (< 3 µV ou < 5 µV). A associação de complicações maternas, tipo de parto, peso ao nascer, idade gestacional, sexo do neonato, procedimentos de reanimação, hipotermia na admissão e Escore para Fisiologia Neonatal Aguda, Extensão Perinatal, versão II (SNAPPE-II) com alterações no eletroencefalograma de amplitude integrada foi avaliada por regressão logística múltipla. Resultados: Um padrão descontínuo ocorreu em 65% dos recém-nascidos e o padrão contínuo ocorreu em 23%. O padrão de surto-supressão foi associado ao parto vaginal (OR 7,6; IC95% 1,1-53,1) e SNAPPE-II ≥ 40 (OR 13,1; IC95% 1,8-95,1). Uma margem inferior do eletroencefalograma de amplitude integrada < 3 µV também foi associada com escore SNAPPE-II ≥ 40 (OR 10,6, IC95% 2,3-49,2), enquanto um valor <5 µV foi associado com menor IG (OR 0,51, IC 95% 0,34-0,76). Não houve associações entre as variáveis perinatais e a ausência de ciclo sono-vigília nas gravações de eletroencefalograma de amplitude integrada no primeiro dia de vida. Conclusão: As variáveis biológicas e a gravidade clínica estão associadas às características eletroencefalográficas dos recém-nascidos prematuros no primeiro dia de vida e devem ser consideradas na prática clínica quando o eletroencefalograma de amplitude integrada é realizado.

RESUMO

OBJECTIVE: Many newborns are investigated and empirically treated for suspected early-onset sepsis (EOS). This study aimed to describe neonatologists' self-identified risk thresholds for investigating and treating EOS and assess the consistency of these thresholds with clinical decisions. STUDY DESIGN: Voluntary online survey, available in two randomized versions, sent to neonatologists from 20 centers of the Brazilian Network on Neonatal Research. The surveys included questions about thresholds for investigating and treating EOS and presented four clinical scenarios with varying calculated risks. In survey version A, only the scenarios were presented, and participants were asked if they would order a blood test or start antibiotics. Survey version B presented the same scenarios and the risk of sepsis. Clinical decisions were compared between survey versions using chi-square tests and agreement between thresholds and clinical decisions were investigated using Kappa coefficients. RESULTS: In total, 293 surveys were completed (145 survey version A and 148 survey version B). The median risk thresholds for blood test and antibiotic treatment were 1:100 and 1:25, respectively. In the high-risk scenario, there was no difference in the proportion choosing antibiotic therapy between the groups. In the moderate-risk scenarios, both tests and antibiotics were chosen more frequently when the calculated risks were included (survey version B). In the low-risk scenario, there was no difference between survey versions. There was poor agreement between the self-described thresholds and clinical decisions. CONCLUSION: Neonatologists overestimate the risk of EOS and underestimate their risk thresholds. Knowledge of calculated risk may increase laboratory investigation and antibiotic use in infants at moderate risk for EOS. KEY POINTS: · Neonatologists overestimate the risk of EOS.. · There is wide variation in diagnostic/treatment thresholds for EOS.. · Clinical decision on EOS is not consistent with risk thresholds.. · Knowledge of risk may increase investigation and treatment of EOS..

RESUMO

This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR) for neonatal life support includes evidence from 7 systematic reviews, 3 scoping reviews, and 12 evidence updates. The Neonatal Life Support Task Force generally determined by consensus the type of evidence evaluation to perform; the topics for the evidence updates followed consultation with International Liaison Committee on Resuscitation member resuscitation councils. The 2020 CoSTRs for neonatal life support are published either as new statements or, if appropriate, reiterations of existing statements when the task force found they remained valid. Evidence review topics of particular interest include the use of suction in the presence of both clear and meconium-stained amniotic fluid, sustained inflations for initiation of positive-pressure ventilation, initial oxygen concentrations for initiation of resuscitation in both preterm and term infants, use of epinephrine (adrenaline) when ventilation and compressions fail to stabilize the newborn infant, appropriate routes of drug delivery during resuscitation, and consideration of when it is appropriate to redirect resuscitation efforts after significant efforts have failed. All sections of the Neonatal Resuscitation Algorithm are addressed, from preparation through to postresuscitation care. This document now forms the basis for ongoing evidence evaluation and reevaluation, which will be triggered as further evidence is published. Over 140 million babies are born annually worldwide (https://ourworldindata.org/grapher/births-and-deaths-projected-to-2100). If up to 5% receive positive-pressure ventilation, this evidence evaluation is relevant to more than 7 million newborn infants every year. However, in terms of early care of the newborn infant, some of the topics addressed are relevant to every single baby born.

RESUMO

Although it is known that nociceptive stimulation in the first postnatal week in rats is useful to model preterm pain, resulting in activation of specific brain areas, as assessed in vivo using manganese-enhanced magnetic resonance imaging (MEMRI), little is known about its long-term effects and sex specificity. Here we aimed to investigate whether inflammatory pain induced in male and female adult rats modify the pattern of brain activation between animals subjected or not to neonatal pain. For this, Complete Freund's adjuvant (CFA) was injected into the left hind paw of rat pups on postnatal day 1 (P1) or P8 to induce inflammatory response. During adulthood, CFA-treated and control animals were injected with CFA 1 hr prior MRI. MEMRI has the ability to enhance the contrast of selective brain structures in response to a specific stimulus, as the pain. MEMRI responses were consistent with activation of nociceptive pathways and these responses were reduced in animals treated with CFA on P1, but increased in animals treated on P8, mainly in the female group. In agreement, P8 female group showed exacerbated responses in the thermal nociceptive test. Using MEMRI, we conclude that the natural ability of adult rats to recognize and react to pain exposition is modified by neonatal painful exposition, mainly among females.

RESUMO

CONTEXT: The International Liaison Committee on Resuscitation Neonatal Life Support Task Force reviewed evidence for the duration of cardiopulmonary resuscitation (CPR) for newborns immediately after birth. OBJECTIVE: To summarize evidence for ongoing CPR on the outcomes of survival, neurodevelopment, and the composite of survival without moderate or severe neurodevelopmental impairment (NDI). DATA SOURCES: Medline, Embase, Evidence-Based Medicine Reviews, Cumulative Index to Nursing and Allied Health Literature, and Scientific Electronic Library Online were searched between inception and February 29, 2020. STUDY SELECTION: Two independent reviewers selected studies of newborns with at least 10 minutes of asystole, bradycardia, or pulseless electrical activity for which CPR is indicated. DATA EXTRACTION: Two independent reviewers extracted data and appraised the risk of bias. RESULTS: In 16 eligible studies, researchers reported outcomes of 579 newborns born between 1982 and 2017. Within individual studies, 2% to 100% of infants survived to last follow-up (hospital discharge through 12 years). Summarized across studies, 237 of 579 (40.9%) newborns survived to last follow-up. In 13 studies, researchers reported neurodevelopmental outcomes of 277 newborns. Of these, 30 of 277 (10.8%) survived without moderate or severe impairment, and 240 of 277 (87%) met the composite outcome of death or NDI (191 died and 49 survived with moderate or severe impairment). LIMITATIONS: There was very low certainty of evidence because of risk of bias and inconsistency. CONCLUSIONS: Infants with ongoing CPR at 10 minutes after birth are at high risk for mortality and neurodisability, but survival without moderate or severe NDI is possible. One specified duration of CPR is unlikely to uniformly predict survival or survival without neuroimpairment.

RESUMO

Objective: To evaluate the effectiveness of a bundle to reduce unplanned extubations (UE) in ventilated newborn infants (NB) and to verify the factors associated to UE.Method: Intervention study with a historical control group in a university hospital neonatal intensive care unit (NICU) between June 2014-May 2015 (Period I) and September 2015-August 2016 (Period II). All ventilated NB were included except those with facial malformations. The bundle (new tracheal tube fixation model, team training, identification of NB at risk of UE, and debriefing after UE episodes) was implemented between Periods I and II. Rates of UE/100 NB ventilated-day were compared between periods for the entire sample and according to the cause: accidental or by medical indication. Factors associated to the first UE episode of each NB were studied by logistic regression.Results: A total of 231 intubations were performed in 120 infants in Period I (gestational age 33.6 ± 4.7 W; birth weight: 2020 ± 929 g) and 212 intubations in 131 infants in Period II (34.2 ± 4.7 W; 2080 ± 997 g). UE occurred in 19.9% and 14.6% of the NB, in Periods I and II, respectively. Accidental extubation and change of the tube by medical indication were observed in 58.7% and 41.3% of UE in Period I and in 51.6% and 48.4% in Period II. Higher birth weight, lower SNAPPE-II score, and daytime period were associated with a lower chance of UE in all newborns.Conclusion: The bundle did not reduce the UE in NB ventilated in NICU but continued control of UE rates is crucial for improved care, especially for immature and critically neonates.What is new about the paper? The study presented a strategy for assessing the causes of unplanned extubations in a Neonatal Intensive Care Unit, considering not only the accidental extubations, but aldo the medical ordered extubations, which contributes to the definition of actions for the reduction of unplanned extubations in the NICU setting.

RESUMO

OBJECTIVE: To gain an understanding of the variation in available resources and clinical practices between neonatal units (NNUs) in the low-income and middle-income country (LMIC) setting to inform the design of an observational study on the burden of unit-level antimicrobial resistance (AMR). DESIGN: A web-based survey using a REDCap database was circulated to NNUs participating in the Neonatal AMR research network. The survey included questions about NNU funding structure, size, admission rates, access to supportive therapies, empirical antimicrobial guidelines and period prevalence of neonatal blood culture isolates and their resistance patterns. SETTING: 39 NNUs from 12 countries. PATIENTS: Any neonate admitted to one of the participating NNUs. INTERVENTIONS: This was an observational cohort study. RESULTS: The number of live births per unit ranged from 513 to 27 700 over the 12-month study period, with the number of neonatal cots ranging from 12 to 110. The proportion of preterm admissions <32 weeks ranged from 0% to 19%, and the majority of units (26/39, 66%) use Essential Medicines List 'Access' antimicrobials as their first-line treatment in neonatal sepsis. Cephalosporin resistance rates in Gram-negative isolates ranged from 26% to 84%, and carbapenem resistance rates ranged from 0% to 81%. Glycopeptide resistance rates among Gram-positive isolates ranged from 0% to 45%. CONCLUSION: AMR is already a significant issue in NNUs worldwide. The apparent burden of AMR in a given NNU in the LMIC setting can be influenced by a range of factors which will vary substantially between NNUs. These variations must be considered when designing interventions to improve neonatal mortality globally.

RESUMO

OBJECTIVE: Evaluate the association between perinatal factors and amplitude-integrated electroencephalogram abnormalities in preterm infants on the first day of life. METHODS: This was a cross-sectional study of 60 infants with gestational age between 23 and 32 weeks, without malformations. Infants were continuously monitored by amplitude-integrated electroencephalogram on the first day of life, for at least 3h. The tracings were recorded and analyzed in each column for the following: burst-suppression pattern, sleep-wake cycle, and amplitude of the lower margin (<3µV or <5µV). The association of maternal complications, mode of delivery, birth weight, gestational age, neonatal sex, resuscitation procedures, hypothermia on admission, and the Score for Neonatal Acute Physiology, Perinatal Extension, Version II [SNAPPE-II]) with amplitude-integrated electroencephalogram alterations was assessed by multiple logistic regression. RESULTS: A discontinuous pattern occurred in 65% of infants, and a continuous pattern occurred in 23%. The burst-suppression pattern was associated with vaginal delivery (OR: 7.6; 95% CI: 1.1-53.1) and SNAPPE-II≥40 (OR: 13.1; 95% CI: 1.8-95.1). A lower margin of the amplitude-integrated electroencephalogram of <3µV was also associated with SNAPPE-II≥40 (OR: 10.6, 95% CI: 2.3-49.2), while a value <5µV was associated with lower GA (OR: 0.51, 95% CI: 0.34-0.76). There were no associations between the perinatal variables and the absence of a sleep-wake cycle in amplitude-integrated electroencephalogram recordings on the first day of life. CONCLUSION: Biological variables and clinical severity are associated with electroencephalographic characteristics of preterm infants on the first day of life and should be considered in clinical practice when amplitude-integrated electroencephalogram is performed.

RESUMO

RESUMO Objetivo Monitorar o sistema auditivo central de crianças nascidas pequenas para a idade gestacional, por meio da avaliação eletrofisiológica da audição, para verificar a ocorrência de eventuais disfunções neurais nesse sistema. Métodos Estudo longitudinal, cuja casuística foi composta por 23 crianças distribuídas em quatro grupos: 1) grupo de quatro crianças nascidas pequenas para a idade gestacional e a termo; 2) grupo de sete crianças nascidas pequenas para a idade gestacional e pré-termo; 3) grupo de quatro crianças nascidas com peso adequado para a idade gestacional e a termo; 4) grupo de oito crianças nascidas adequadas para a idade gestacional e pré-termo, cuja idade ao final da pesquisa foi de 3 anos (variação entre 34 e 39 meses). O critério de inclusão foi presença bilateral de emissões otoacústicas transientes. Todas as crianças foram submetidas ao potencial evocado auditivo de tronco encefálico ao nascimento, aos 6 meses e aos 3 anos de idade e à pesquisa do potencial evocado auditivo de longa latência aos 3 anos. Resultados crianças nascidas pequenas para a idade gestacional e a termo tiveram maior ocorrência de alterações, em relação aos demais grupos, com aumento da latência das ondas III e V e interpicos I-III e I-V. Todas apresentaram resultados normais no potencial evocado auditivo de longa latência. Conclusão Crianças nascidas pequenas para a idade gestacional e a termo apresentam disfunções na condução neural no tronco encefálico e devem ser consideradas de risco para alterações do desenvolvimento das habilidades auditivas necessárias para garantir qualidade de processamento da informação acústica.


ABSTRACT Purpose To follow up the central auditory system of children born small for gestational age, through electrophysiological evaluation of hearing, in order to verify the occurrence of possible neural dysfunctions in this system. Methods A longitudinal study was carried out with 23 children divided into four groups: Term-born group, subdivided into small for gestational age (four children) and four children born with appropriate weight for gestational age, whose age at the end of the research was three years old. Preterm group subdivided into small for gestational age (seven children), and appropriate for gestational age (eight children), whose corrected age, at the end of the research was three years old. All children were subjected to assessment of auditory brainstem auditory evoked potentials at birth, at six months and at three years of age, and Long-Latency Auditory Evoked Potential at three years. Results children born at term and small for gestational age had a higher occurrence of hearing alterations in relation to the other groups, with increased latency of waves III and V and interpeaks I-III and I-V. All children presented normal evaluation in the Long-Latency Auditory Evoked Potential. Conclusion Children born term and small for gestational age present dysfunctions in neural conduction in the brainstem and should be considered at risk for alterations in the development of the auditory skills that are necessary to guarantee quality of acoustic information processing.

RESUMO

ABSTRACT Objective: To evaluate the association between intra-ventricular hemorrhage and habituation responses to external stimuli in preterm infants at 36-38 weeks post-conceptual age. Methods: Cross-sectional study of infants with gestational age <32 weeks. Intra-ventricular hemorrhage was identified by cranial ultrasonography and classified according to Papile et al. (1978). The luminous (flashlight), sound (rattle, bell), and tactile stimuli were presented, and the responses were scored according to Lester and Tronik (2004). Habituation response scores were compared between groups by Student's t-test. The association between IVH and habituation scores was evaluated by linear regression adjusted for GA, clinical severity score, post-conceptual age at habituation assessment, sepsis, and bronchopulmonary dysplasia. Results: Sixty-five infants were studied, 20 with intra-ventricular hemorrhage (16 grades I/II; four grades III/IV) and 45 without intra-ventricular hemorrhage. Infants with intra-ventricular hemorrhage had lower gestational age (28.2 ± 2.2 vs. 29.7 ± 1.7 weeks) and birth weight (990 ± 305 vs. 1275 ± 360 g). Infants with intra-ventricular hemorrhage at 36-38 weeks post-conceptual age had lower habituation scores to light (4.21 ± 2.23 vs. 6.09 ± 2.44), rattle (3.84 ± 2.12 vs. 6.18 ± 2.27), and bell (3.58 ± 1.74 vs. 5.20 ± 2.47) after controlling for confounders. No differences were found for tactile stimulus. Conclusion: Infants with gestational age <32 weeks and intra-ventricular hemorrhage had poorer habituation responses to external stimuli than those without intra-ventricular hemorrhage at 36-38 weeks post-conceptual age.


RESUMO Objetivo: Avaliar a associação entre hemorragia intraventricular e as respostas de habituação a estímulos externos em neonatos prematuros com idade pós-conceptual de 36-38 semanas. Métodos: Estudo transversal com neonatos com idade gestacional < 32 semanas. A hemorragia intraventricular foi identificada por ultrassonografia craniana e classificada de acordo com Papile et al. (1978). Os estímulos luminosos (lanterna), sonoros (chocalho, sino) e táteis foram apresentados e as respostas foram pontuadas de acordo com Lester & Tronik (2004). Os escores das respostas de habituação foram comparadas entre os grupos pelo teste t de Student. A associação entre a hemorragia intraventricular e os escores de habituação foi avaliada por regressão linear ajustada para a idade gestacional, escore de gravidade clínica, idade pós-conceptual na avaliação da habituação, sepse e displasia broncopulmonar. Resultados: 65 neonatos foram estudados, 20 com hemorragia intraventricular (16 graus I/II;4 graus III/IV) e 45 sem hemorragia intraventricular. Os neonatos com hemorragia intraventricular apresentaram menor idade gestacional (28,2 ± 2,2 vs. 29,7 ± 1,7 semanas) e peso ao nascer (990 ± 305 vs. 1275 ± 360 g). Os neonatos com hemorragia intraventricular na idade pós-conceptual de 36-38 semanas apresentaram escores de habituação menores a luz (4,21 ± 2,23 vs. 6,09 ± 2,44), chocalho (3,84 ± 2,12 vs. 6,18 ± 2,27) e campainha (3,58 ± 1,74 vs. 5,20 ± 2,47) após controle para variáveis de confusão. Nenhuma diferença foi encontrada para os estímulos táteis. Conclusão: Neonatos com idade gestacional < 32 semanas e hemorragia intraventricular apresentaram respostas de habituação piores a estímulos externos que os sem hemorragia intraventricular, na idade pós-conceptual de 36-38 semanas.

RESUMO

This prospective cohort study aimed to assess the association of admission hypothermia (AH) with death and/or major neonatal morbidities among very low birth weight (VLBW) preterm infants based on the relative performance of 20 centers of the Brazilian Network of Neonatal Research. This is a retrospective analysis of prospectively collected data using the database registry of the Brazilian Network on Neonatal Research. Center performance was defined by the relative mortality rate using conditional inference trees. A total of 4356 inborn singleton VLBW preterm infants born between January 2013 and December 2016 without malformations were included in this study. The centers were divided into two groups: G1 (with lower mortality rate) and G2 (with higher mortality rate). Crude and adjusted relative risks (RR) and 95% confidence intervals (95%CI) were estimated by simple and multiple log-binomial regression models. An AH rate of 53.7% (19.8-93.3%) was significantly associated with early neonatal death in G1 (adjusted RR 1.41, 95% CI 1.09-1.84) and G2 (adjusted RR 1.29, 95%CI 1.01-1.65) and with in-hospital death in G1 (adjusted RR 1.29, 95%CI 1.07-1.58). AH was significantly associated with a lower frequency of necrotizing enterocolitis (adjusted RR 0.58, 95%CI 38-0.88) in G2.Conclusion: AH significantly associated with early neonatal death regardless of the hospital performance. In G2, an unexpected protective association between AH and necrotizing enterocolitis was found, whereas the other morbidities assessed were not significantly associated with AH. What is Known: • Admission hypothermia is associated with early neonatal death. • The association of admission hypothermia with major neonatal morbidities has not been fully established. What is New: • Admission hypothermia was significantly associated with early neonatal and in-hospital death in centers with the lowest relative mortality rates. • Admission hypothermia was not associated with major neonatal morbidities and with in-hospital death but was found to be a protective factor against necrotizing colitis in centers with the highest relative mortality rates.

RESUMO

AIM: Evaluate prospectively the neurobehavior of preterm infants (PT). STUDY DESIGN: Cohort of PT (gestational age(GA) <32weeks), evaluated biweekly from 32 to 48 weeks post-menstrual age (PMA) by NICU Network Neurobehavioral Scale (NNNS). Scores were compared by repeated Measures ANOVA. Scores of PT were compared to those of full-term infants, matched for gender by ANOVA. RESULTS: 39 PT (mean ± SD: GA 29.2 ± 2.0 weeks; birthweight 1100 ± 331g) were studied. As PMA progressed, PT showed increasing scores in habituation, attention, arousal, regulation, maneuvers for orientation, quality of movements and hypertonicity, and decreasing scores in excitability, lethargy, non-optimal reflexes, asymmetry, hypotonicity, and signs of stress/withdrawal. At 40 weeks PMA, PT were similar to term neonates assessed in the first days of life, except for less habituation, regulation capacity and excitability, and more hypotonia. CONCLUSION: At 40 weeks PMA, PT reached the performance of full-term neonates evaluated in the first days of life in most neurobehavior domains.

RESUMO

ABSTRACT Objective: To measure the level of satisfaction regarding the usability of a neonatal health information system and identify if demographic factors can influence the usability of a health information system. Methods: A cross-sectional, exploratory study was carried out with a convenience sample of 50 users of the Brazilian Neonatal Research Network. The instrument chosen for the usability evaluation was the System Usability Scale between February and March 2017. The statistical analysis of the collected variables was carried out in order to describe the sample, to quantify the level of satisfaction of the users and to identify the variables associated with the level of satisfaction. Results: The female gender represented 75% of the sample. The mean age was 52.8 years; 58% had a doctoral degree, average time of graduation was 17 years, with area of practice in medicine (neonatology), with intermediate knowledge in computer science (74%) and mean system use time of 52 months. Regarding usability, 94% rated the system as "good", "excellent" or "better than imaginable". The usability of the system was not associated with age, gender, education, profession, area of practice, knowledge in computer science and time of system use. Conclusion: The level of satisfaction of the computerized health system user was considered good. No demographic factors were associated with the satisfaction of the users.


RESUMO Objetivo: Mensurar o grau de satisfação de profissionais de saúde quanto à usabilidade de um sistema de informação em saúde neonatal e identificar os fatores que podem influenciar na satisfação do usuário frente à usabilidade. Métodos: Estudo transversal e exploratório realizado com 50 profissionais de saúde integrantes dos centros da Rede Brasileira de Pesquisas Neonatais. Para avaliação da usabilidade foi utilizado o instrumento System Usability Scale entre fevereiro e março de 2017. Realizou-se a análise estatística descritiva e inferencial das variáveis coletadas, com a finalidade de descrever a amostra, quantificar o grau de satisfação dos usuários e identificar as variáveis associadas ao grau de satisfação do usuário em relação à usabilidade. Resultados: Da população avaliada, 75% era do sexo feminino, com idade média 52,8 anos, 58% com pós-graduação (doutorado); tempo médio da última formação de 17 anos; área de atuação em medicina (neonatologia), grau intermediário de conhecimento em informática e tempo de utilização média do sistema de 52 meses. Quanto à usabilidade, 94% avaliaram o sistema como "bom", "excelente" ou "melhor impossível". A usabilidade do sistema não foi associada a idade, sexo, escolaridade, profissão, área de atuação, nível de conhecimento em informática e tempo de uso do sistema. Conclusões: O grau de satisfação do usuário do sistema informatizado de saúde foi considerado bom. Não foram identificados fatores demográficos que influenciassem sua avaliação.
