RESUMO
INTRODUCTION: Patent ductus arteriosus (PDA) in preterm infants has been associated with increased mortality and comorbidities. This study aimed to characterize the population of preterm infants diagnosed with PDA and to identify predictive factors of response to medical treatment of PDA. METHODS: An eight-year retrospective observational study was carried out, which included all preterm infants with a gestational age (GA) between 23 and 32 weeks diagnosed with PDA, admitted to the Neonatal Unit of the CHUSJ. Univariate comparative analysis was performed, and models for predicting the effectiveness of PDA treatment with ibuprofen were explored by multivariate logistic regression analysis. RESULTS: 115 cases were included and 34 were excluded, with a final sample of 81 preterm infants with PDA. The univariate analysis revealed significant differences in the closure efficacy via medical treatment with ibuprofen in several variables, and a multivariate logistic regression model was obtained (discriminative capacity 72.2%, sensitivity 98.1%, specificity 57.1%), taking into account the effect of GA, type of delivery, need for diuretics treatment and platelet transfusion. CONCLUSION: This study enabled the population of preterm infants diagnosed with PDA to be characterized and the identification of a predictive model that can help predict the efficacy of medical treatment and thus contribute to optimizing the medical approach to the non-responders.
RESUMO
BACKGROUND: Several interventional cardiology procedures are required in neonates with congenital heart disease. Interventional cardiology procedures have a higher risk of cardiac arrest compared to other interventions. At present, there is great heterogeneity in the perioperative management of congenital heart disease neonates undergoing diagnostic cardiac catheterization or therapeutic cardiac catheterization. STUDY OBJECTIVES: Primary aim: Provide a systematic review of the most effective and/or safe anesthetic and perioperative management in neonates with congenital heart disease who undergo diagnostic cardiac catheterization or therapeutic cardiac catheterization. Secondary aim: Identify the medications, monitoring parameters and airway management used in the same population. DESIGN: Systematic literature review. SETTING: Catheterization laboratory. METHODS: Literature was searched (December 2017) in electronic databases Medline, EMBASE, ScienceDirect, BIREME-Lilacs-Biblioteca Virtual de la Salud, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Health Technology Assessment Database. MAIN RESULTS: From 130 records identified, four studies met inclusion criteria and quality assessment. None of the studies were relevant to the primary objective. Regarding the secondary objectives, one study compared the efficacy and adverse effects of racemic ketamine and its S(+) ketamine enantiomer, one study reported the efficacy of subarachnoid anesthesia for high-risk children undergoing diagnostic cardiac catheterization, one study identified the factors associated to high severity adverse events related to sedation, anesthesia and airway, and one study retrospectively analyzed cardiac catheterization procedures in neonates weighing less than 2.5 kg. CONCLUSION: There are no evidence-based recommendations available for congenital heart disease neonates undergoing cardiac catheterization. More studies are required to evaluate the ideal anesthetic and perioperative management in this population.

OBJECTIVE: To evaluate the influence of gestational and perinatal factors on body composition and birth weight of full-term newborns. METHOD: This was a cross-sectional study, within a prospective cohort, consisting of 124 postpartum women and their newborns. Data included the following: maternal age; ethnicity; pre-gestational body mass index; gestational weight gain; parity; gestational morbidities (hypertension and gestational diabetes mellitus); gestational age at birth; birth weight; and newborn's gender. Anthropometric and body composition data of the newborns were collected using air-displacement plethysmography (PeaPod® Infant Body Composition System-LMI; Concord, CA, USA). The stepwise technique was applied to a multiple linear regression model. RESULTS: The significant variables in the model that explained 84% of the variation in neonatal fat-free mass were: birth weight; maternal age; newborn's gender and gestational age. For body fat mass: birth weight; newborn's gender; gestational arterial hypertension; gestational diabetes; and gestational weight gain. These variables explained 60% and 46% of fat mass, in grams and as a percentage, respectively. Regarding birth weight, the significant factors were gestational age, pre-gestational BMI, and gestational weight gain. Female newborns showed higher body fat mass and male newborns had higher fat-free mass. CONCLUSION: Gestational and perinatal factors influence neonatal body composition. Early identification of these gestational factors, which may be modifiable, is necessary to prevent obesity and chronic noncommunicable diseases in the future.

OBJECTIVE: This study analyzed the relationship between latent iron deficiency evaluated by ferritin, and the myelination of the central nervous system evaluated through the brainstem evoked response audiometry test. METHOD: A total of 109 full-term newborns, born without anemia and risk factor for hearing deficiency, were enrolled. After delivery, umbilical cord blood was collected to determine ferritin and hematocrit levels. The brainstem evoked response audiometry test was carried out in the first 28 days of life. Analysis was performed between the control group (n=71) with ferritin greater than 75ng/mL, and the latent iron deficiency group (n=38) with ferritin between 11 and 75ng/mL. Results were presented as mean±standard deviation. Statistical analysis was performed using GraphPad prism7 and SPSS with a significance level of 5%. RESULTS: A significant higher V-wave (p=0.02) and interpeak intervals I-III (p=0.014), I-V (p=0.0003), and III-V (p=0.0002) latencies were found in the latent iron deficiency group, as well as a significant inversely proportional correlation between ferritin and the same wave and intervals (p=0.003, p=0.0013, p=0.0002, p=0.009, respectively). Multiple correlation analysis showed a significant correlation of latent iron deficiency with all interpeak intervals, even taking into account newborn gestational age. CONCLUSION: Iron deficiency anemia is a prevalent pathology; this study showed auditory delayed maturation associated to intrauterine iron deficiency, even in its latent form. This reinforces the importance of adopting effective measures, on a global scale, to prevent and treat this pathology in different life periods, especially in the most vulnerable population.

We present a rare case of a levoatrial cardinal vein identified during the work-up of a patient with coarctation of the aorta. Early diagnosis and repair in the neonatal period prevented future manifestations of left-to-right shunt and the need for reoperations, in contrast with the later-age presentation of this congenital anomaly. An integrative approach was crucial for prompt detection, intraoperative confirmation and complete one-stage repair.

INTRODUCTION: The study of the threshold level of cortical auditory response in adults has been investigated in previous studies. Due to maturational issues, little is known about these responses in neonates. Technological advances with automatic analysis devices now allow investigation in specific populations. Thus, new studies are needed to establish the feasibility of using this auditory potential to identify the lowest levels of responses in children. OBJECTIVE: Verify and compare latency and amplitude in 80dBnNA and the minimum level of cortical auditory response in term and preterm neonates. METHODS: A cross-sectional, comparative study involving 59 neonates, 35 full-term births and 24 preterm births, with positive results in the Neonatal Hearing Screening. The Hearlab system was used to investigate the P1i auditory potential with tone burst stimulus at frequencies of 500, 1000, 2000 and 4000Hz. The minimum response level search ranged from 80 to 0dBNA and was detected automatically. The results were compared between groups, evaluating the latency and amplitude in 80dBNA and the minimum level of cortical auditory response. RESULTS: The mean values obtained for the minimum level of cortical auditory response in term group were 26±8.81; 26.14±6.97; 29±7.65 and 29.43±7.04dBNA and for preterm neonates of 31.96±10.41; 34.13±11.34; 33.64±11.03 and 37.73±11.92dBNA, for the frequencies of 500, 1000, 2000 and 4000Hz, respectively. There was a difference between groups for the latency of P1i at 4000Hz and the minimum response levels at 500, 1000 and 4000Hz, with higher values for preterm infants. CONCLUSION: It was possible to obtain latency and amplitude values at 80dBnNA and the minimum level of cortical response in term and preterm newborns, with different results between groups, with higher values in those born preterm.

OBJECTIVES: Describe the results of the red reflex test in full-term newborns, as well as identify factors associated with red reflex test outcome and compare hospital length of stay between patients with inconclusive and normal red reflex test results. METHODS: Descriptive cross-sectional study of the results of the red reflex test performed in a tertiary hospital maternity unit between 2014 and 2018. A nested case-control study was also performed to search for anthropometric, gestational, and neonatal variables associated with the outcome of the red reflex test. RESULTS: There were121 identified cases of inconclusive red reflex test in 11,833 newborns. Sixteen alterations were confirmed, four considered severe: two cases of congenital glaucoma, one of cataract, and one of coloboma. Mean birth weight (p=0.04), length (p=0.03), and head circumference (p=0.02) were lower in patients with inconclusive red reflex test; however without a relevant effect size (d=-0.21, -0.22, and -0.25, respectively).The proportion of white, mixed-race, and black patients was significantly different between the groups (p<0.001), with a higher chance of inconclusive results in mixed-race (OR=2.22) and black (OR=3.37) patients when compared to whites. An inconclusive red reflex test led to an increase in hospital length of stay from 62 to 82hours (p<0.001). CONCLUSIONS: The red reflex test was able to identify four severe alterations in 11,833 newborns (0.03%). In the 121 newborns in which the red reflex test was classified as inconclusive, there was a 20-hour increase in the hospital length of stay, but a severe alteration was confirmed in only 3.3% of them. Differences in red reflex between white, mixed-race, and black patients should be considered.

OBJECTIVE: To describe and analyze the prognosis of children during the first year of life with a diagnosis of congenital diaphragmatic hernia admitted between the years 2005 and 2015 in the Neonatal Intensive Care Unit. METHOD: In a retrospective cohort, 129 children with a diagnosis of congenital diaphragmatic hernia were studied. The prognostic factors were analyzed, whereupon prenatal, delivery, and postnatal exposure variables were associated with death during the first year of life. The odds ratio and the confidence interval (95% CI) were calculated for all the studied variables, using the chi-squared test and Student's t-test. RESULTS: The study included 129 children hospitalized from January of 2005 to December of 2015. Seventy-nine (61%) patients died, 50 survived, and 33 had other associated malformations. Among the prognostic factors, the following were significant and increased the chance of death: polyhydramnios (p=0.001), gestational age of the earliest diagnosis (p=0.004), associated congenital abnormalities (OR: 3.013, p=0.022), pO2 of the first gasometry (p=0.000), pCO2 of the first gasometry (p=0.000), presence of pulmonary hypoplasia (OR: 3.074, p=0.000), use of preoperative vasoactive drugs (OR: 2.881, p=0.000), and use of nitric oxide (OR: 1.739, p=0.000). The presence of only intestines in the hernia content was a protective factor (OR: 0.615, p=0.001). CONCLUSION: The mortality in the first year of life in patients with congenital diaphragmatic hernia in this study was 61% in the years 2005-2015. Among the prognostic factors that demonstrated a significant effect, pulmonary hypoplasia had the greatest impact.

OBJECTIVE: To verify whether early intervention focused on the family improves the cognitive, motor, and language development of children born preterm and/or at social risk in the first 3 years of life. SOURCE OF DATA: Meta-analysis of clinical trials published between 2008 and 2018, in the following databases: CINAHL, MEDLINE - PubMed, MEDLINE - BVS, LILACS - BVS, IBECS - BVS, PEDro and Cochrane Reviews. Experimental studies on early interventions focused on the family, whose target groups were children born preterm and/or at social risk, with assessment of cognitive and/or motor and/or language development up to 3 years were included. The studies were rated using the PEDro Scale. DATA SYNTHESIS: Twelve studies were included from a total of 3378 articles. Early intervention focused on the family contributed to the development of the cognitive (Standardized Mean Difference - SMD=0.48, 95% CI: 0.34-0.61) and motor (SMD=0.76, 95% CI: 0.55-0.96) domains of preterm infants. Regarding cognitive development, performance improvement was observed at 12, 24 and 36 months, while in the motor domain, the effect was observed only at 12 months in preterm infants. There was no benefit of the intervention in the cognitive, motor, and language outcomes of children with the social risk factor associated to biological risk. CONCLUSION: Early intervention focused on the family has a positive effect on the cognition of preterm infants. The effect on motor development was lower, possibly due to the emphasis on interventions in family-child interaction. The effect of interventions on the development of children at social risk and on the language domain was inconclusive, due to the scarcity of studies in the area.

OBJECTIVE: Perform a systematic review and meta-analysis to assess the effectiveness and complications caused by the use of the high-flow nasal cannula in relation to the post-extubation continuous positive airway pressure system in preterm newborns. DATA SOURCES: The searches were performed from January 2013 to December 2018 in the PubMed and Embase databases, as well as a manual search on the internet. DATA SYNTHESIS: Two reviewers independently conducted the search, and a third reviewer resolved questions that arose. Ninety-eight articles from the chosen sources were evaluated, and 66 were discarded because they did not meet the inclusion criteria (inadequate topic, age range, or design, in addition to the duplicates). Fifteen articles were read in full, and five more were discarded due to inadequacy to the topic or design. There were ten articles left for systematic review and four for meta-analysis. The study showed non-inferiority in terms of therapeutic failure of the high-flow nasal cannula in relation to continuous positive airway pressure after extubation of preterm newborns. In the meta-analysis, nasal trauma was significantly lower in patients submitted to the high-flow nasal cannula compared to those using continuous positive airway pressure (p<0.00001). CONCLUSION: The high-flow nasal cannula is not inferior to continuous positive airway pressure for post-extubation respiratory support in preterm newborns with a gestational age of 32 weeks or less and greater than 28 weeks, in addition to resulting in less nasal trauma.

OBJECTIVES: To analyze the risk factors for neonatal death in Florianópolis, the Brazilian city capital with the lowest infant mortality rate. METHOD: Data were extracted from a historical cohort with 15,879 live births. A model was used that included socioeconomic, behavioral, and health service use risk factors, as well as the Apgar score and biological factors. Risk factors were analyzed by hierarchical logistic regression. RESULTS: Based on the multivariate analysis, socioeconomic factors showed no association with death. Insufficient prenatal consultations showed an OR of 3.25 (95% CI: 1.70-6.48) for death. Low birth weight (OR 8.42; 95% CI: 3.45-21.93); prematurity (OR 5.40; 95% CI: 2.22-13.88); malformations (OR 4.42; 95% CI: 1.37-12.43); and low Apgar score at the first (OR 6.65; 95% CI: 3.36-12.94) and at the fifth (OR 19.78; 95% CI: 9.12-44.50) minutes, were associated with death. CONCLUSION: Differing from other studies, socioeconomic conditions were not associated with neonatal death. Insufficient prenatal consultations, low Apgar score, prematurity, low birth weight, and malformations showed an association, reinforcing the importance of prenatal access universalization and its integration with medium and high-complexity neonatal care services.

OBJECTIVES: There are several factors that influence the postnatal growth of preterm infants. It is crucial to define how to evaluate the growth rate of each preterm child and its individual trajectory, the type of growth curve, either with parameters of prescriptive curves for healthy preterm infants with no morbidities or, in the case of preterm infants and their "bundle of vulnerabilities", growth curves that may represent how they are actually growing, with the aim of directing appropriate nutritional care to each gestational age range. DATA SOURCES: The main studies with growth curves for growth monitoring and the appropriate nutritional adjustments that prioritized the individual trajectory of postnatal growth rate were reviewed. PubMed and Google Scholar were searched. DATA SYNTHESIS: The use of longitudinal neonatal data with different gestational ages and considering high and medium-risk pregnancies will probably be essential to evaluate the optimal growth pattern. CONCLUSIONS: Prioritizing and knowing the individual growth trajectory of each preterm child is an alternative for preterm infants with less than 33 weeks of gestational age. For larger preterm infants born at gestational age >33 weeks, the Intergrowth 21st curves are adequate.

OBJECTIVE: The literature indicates a single universal cut-off point for weight loss after birth for the risk of hypernatremia, without considering other factors. The aim of this study was to construct and internally validate cut-off points for the percentage weight loss associated with the risk of hypernatremia, taking into account risk factors. METHODS: A prospective study with a three-day follow-up was conducted in 165 neonates with a gestational age ≥35 weeks. The main outcome variable was mild or moderate hypernatremia (serum sodium≥145mmol/L). Secondary variables (risk factors) were maternal and infant variables. A multivariate logistic regression model was constructed to predict hypernatremia, obtaining its probability and the optimal discriminant cut-off point for hypernatremia (receiver operating characteristic analysis). Based on this point, threshold weight loss values were obtained according to the other variables. These values were internally validated by bootstrapping. RESULTS: There were 51 cases (30.9%) of hypernatremia. The mean percentage weight loss for hypernatremic infants was 8.6% and 6.0% for the rest. Associated variables in the multivariate model included greater weight loss, male gender, higher education level, multiparity, and cesarean delivery. The model had an area under the receiver operating characteristic curve of 0.84 (sensitivity=77.6%; specificity=73.2%). Similar values were obtained in the bootstrapping validation. The lowest percentage weight loss was 4.77%, for cesarean delivery in male infants of mothers with a higher education level. CONCLUSIONS: The weight loss percentage values depended on the type of delivery, parity, newborn gender, and level of maternal education. External studies are required to validate these values.

ABSTRACT BACKGROUND AND OBJECTIVES: This study is justified by the interest of the area in question and the curiosity to know what methods and procedures are carried out on newborn pain, to help professionals and students to better understand the subject, in addition to showing the results obtained and help to improve care for this public. The objective of this study was to know the perceptions of nursing professionals working in the Neonatal Intensive Care Unit (NICU) and in the nursery about newborn (NB) pain and its management. METHODS: A descriptive, exploratory study with a qualitative approach. Technicians, assistants, and nurses who worked for at least three months in the NICU and nursery units of a philanthropic hospital participated in the research. Professionals who were on leave due to vacation or leave of any kind during the study period were excluded. A semi-structured interview was used, and a data analysis was carried out according to the content analysis proposed by Bardin. RESULTS: Twelve professionals, nine nursing technicians and three nurses participated in the research, of these, seven professionals working in the NICU and five in the nursery. From the analysis of the statements of the study participants, two categories emerged: perceptions of professionals regarding the identification and cause of pain in the NB; and NB pain assessment and management. CONCLUSION: The present study reveals the importance of identifying pain in the NB and its effective management, as the lack of appreciation for it can lead to more stress for the NB. Crying was the main characteristic identified by professionals when there is a NB with pain or some discomfort, therefore, mainly non-pharmacological methods are used for relief. Effective management should be seen as an indicator of the quality of care provided, ensuring humanized care, free from damage and with quality.
RESUMO JUSTIFICATIVA E OBJETIVOS: Este estudo se justifica pelo interesse da área em questão e pela curiosidade de saber quais os métodos e procedimentos realizados sobre a dor do recém-nascido, a fim de auxiliar profissionais e estudantes a entenderem melhor sobre o assunto, além de mostrar os resultados obtidos para ajudar na melhora do cuidado deste público. O objetivo deste estudo foi conhecer as percepções dos profissionais de enfermagem que atuam na Unidade de Terapia Intensiva Neonatal (UTIN) e no Berçário acerca da dor dos recém-nascidos (RN) e seu manejo. MÉTODOS: Estudo descritivo, exploratório, de abordagem qualitativa. Participaram da pesquisa técnicos, auxiliares e enfermeiros que atuavam, no mínimo, três meses nas UTIN e Berçário de um hospital filantrópico. Foram excluídos os profissionais que estavam afastados por motivo de férias ou licença de qualquer natureza durante o período do estudo. Utilizou-se a entrevista semiestruturada e a análise dos dados foi realizada de acordo com o proposto por Bardin. RESULTADOS: Participaram da pesquisa 12 profissionais, nove técnicas de enfermagem e três enfermeiras, destes, sete profissionais atuam na UTIN e cinco no berçário. A partir da análise dos depoimentos das participantes do estudo, emergiram duas categorias: percepções dos profissionais quanto à identificação e causa da dor do RN; e avaliação e manejo da dor. CONCLUSĆO: O presente estudo revelou a importância da identificação da dor no RN e o manejo eficaz, visto que a não valorização deste pode resultar em mais estresse para o RN. Notou-se que o choro é a principal característica identificada pelas profissionais quando se tem um RN com dor ou algum desconforto e que são utilizados principalmente os métodos não farmacológicos para o alívio. O manejo efetivo deve ser visto como um indicador de qualidade da assistência oferecida, garantindo um atendimento humanizado, livre de lesões e com qualidade.

Abstract We aimed to analyze factors associated with neonatal near-miss in Cuiabá, State of Mato Grosso, Brazil by performing a case-control study of live births in a capital city of central-western Brazil from January 2015 to December 2018 that included 931 cases and 1,862 controls. Data were obtained from the Live Births Information System and the Mortality Information System and variables were organized according to the hierarchical model. Association was analyzed by logistic regression with a 5% significance level. Data were expressed as crude and adjusted odds ratio (OR) and respective confidence intervals (95%CI). The following factors were associated with neonatal near miss: mothers with two (OR = 1.63; 95%CI: 1.01-2.63) or three or more previous pregnancies (OR=1.87; 95%CI: 1.09-3.21), without any live children (OR = 2.57; 95%CI: 1.56-4.24 ) or one live child at birth (OR = 1.53; 95%CI: 1.04-2.26), multiple pregnancy (OR = 4.57; 95%CI: 2.95-7.07), fewer than six prenatal consultations (OR = 2.20; 95%CI: 1.77-2.72), whose deliveries took place in public/university hospitals (OR = 2.25; 95%CI: 1.60-3.15) or philanthropic hospitals (OR = 1.62; 95%CI: 1.16-2.26), with non-cephalic presentation (OR = 2.71 95%CI: 1.87-3.94) and uninduced labor (OR = 1.47; 95%CI: 1.18-1.84).
RESUMO
ABSTRACT Objective: To assess the rib cage expansion and respiratory rate in newborns using an abdominal stabilization band. Methods: The study included 32 newborns of both genders, with gestational age between 35 and 41 weeks. The abdominal stabilization band was used for 15 minutes between the xiphoid process and the anterosuperior iliac crest, with an abdominal contention 0.5cm smaller than the abdominal circumference. The rib cage expansion was evaluated by a breathing transducer (Pneumotrace II™) three minutes before using the band, during the use (15 minutes), and ten minutes after removing the band. The Shapiro-Wilk test verified data normality, and the Wilcoxon test compared the variables considering rib cage expansion and respiratory rate. Significance was set to p<0.05. Results: There was an increase in respiratory rate when comparing before and ten minutes after removing (p=0.008) the abdominal stabilization band, as well as when comparing during its use and ten minutes after its removal (p=0.001). There was also an increase in rib cage expansion when comparing before and during the use of the abdominal stabilization band (p=0.005). Conclusions: The use of the abdominal stabilization band promoted an increase in the rib cage expansion and respiratory rate in the assessed newborns and may be a viable option to improve the respiratory kinematics of this population.
RESUMO Objetivo: Avaliar a expansibilidade torácica e a frequência respiratória em recém-nascidos que fizeram uso de uma faixa de estabilização abdominal. Métodos: O estudo incluiu 32 recém-nascidos de ambos os sexos, com idade gestacional entre 35 e 41 semanas. A faixa de estabilização abdominal foi mantida por 15 minutos entre o processo xifoide e a espinha ilíaca anterossuperior, com contenção abdominal 0,5 cm menor do que a circunferência abdominal. A expansibilidade torácica foi avaliada por um transdutor piezoelétrico (Pneumotrace II™) 3 minutos antes do uso da faixa, durante 15 minutos, e 10 minutos após sua retirada. A normalidade das variáveis foi testada pelo teste de Shapiro-Wilk e a análise comparativa da expansibilidade torácica e da frequência respiratória foi realizada por meio do teste t pareado, considerando-se p<0,05. Resultados: Houve aumento da frequência respiratória quando comparados os tempos antes do uso da faixa e 10 minutos após a retirada (p=0,008), bem como quando comparados os tempos durante o uso e 10 minutos após a retirada da faixa (p=0,001). Houve aumento da expansibilidade torácica quando comparados os tempos antes e durante o uso da faixa (p=0,005). Conclusões: O uso da faixa de estabilização abdominal conferiu aumento da expansibilidade torácica e da frequência respiratória nos recém-nascidos estudados, podendo ser uma opção viável para a melhora da cinemática respiratória dessa população.
RESUMO
RESUMO Objetivo Analisar a hiperbilirrubinemia como indicador para a realização do protocolo de risco na triagem auditiva neonatal (TAN) e no monitoramento auditivo em neonatos a termo e prematuros. Método Trata-se de um estudo observacional, transversal e retrospectivo. Foram incluídas 554 crianças nascidas em uma maternidade pública, subdivididas em dois grupos: (G1) com 373 recém-nascidos a termo; (G2) com 181 neonatos prematuros. Os dados foram coletados nos prontuários dos participantes, a fim de se obter informações referentes ao resultado da TAN realizada por meio do registro do Potencial Evocado Auditivo de Tronco Encefálico, às condições de nascimento, características clínicas, intervenções realizadas, resultados do primeiro exame de bilirrubina total (BT) e bilirrubina indireta (BI) e do pico de BT e BI. Realizou-se análise estatística descritiva e inferencial dos dados, com adoção do nível de significância de 5%. Resultados No teste da TAN, foram observadas taxas de encaminhamento para reteste inferiores no G1 em relação ao G2. Não houve diferença entre os grupos quanto à ocorrência do tipo de parto, sexo, presença de incompatibilidade sanguínea Rh e ABO, deficiência de enzima G6PD e realização de fototerapia. Em relação aos níveis de BT e BI no primeiro exame e no momento do pico, não houve diferenças entre os neonatos com resultado "passa" e "falha" na TAN-teste nos dois grupos. Conclusão Os níveis de bilirrubina no período neonatal abaixo dos valores recomendados para indicação de exsanguineotransfusão não estão diretamente relacionados ao resultado "falha" na TAN em neonatos a termo e prematuros.
ABSTRACT Purpose To analyze hyperbilirubinemia as an indicator for the definition of risk protocol in newborn hearing screening (NHS) and in auditory monitoring in full-term and preterm neonates. Methods This is an observational, cross-sectional and retrospective study. A total of 554 children born in a public maternity hospital were included and divided into two groups: (G1) with 373 full-terms neonates; (G2) with 181 preterm neonates. Data were collected from the participant's medical records to obtain information regarding the result of the NHS, performed by recording the automated auditory brainstem response (AABR), birth conditions, clinical characteristics, interventions performed, and results of the first test of total bilirubin (TB) and indirect bilirubin (IB) as well as the peak of TB and IB. A descriptive statistical analysis of the results was performed, and the level of significance adopted was 5%. Results On the NHS test, quotes of retest referral rates were smaller in G1 when compared to G2. There was no significant difference between the groups regarding type of delivery, gender, presence of Rh and ABO incompatibility, G6PD enzyme deficiency, and performance of phototherapy. TB and IB levels at the first exam and at peak time did not differ between neonates with "pass" and "fail" results on the NHS test in both groups. Conclusion Bilirubin levels in the neonatal period below the recommended values for indication of exchange transfusion are not directly related to the "fail" result on the NHS tests in term and preterm neonates.
RESUMO
INTRODUÇÃO: A fisioterapia aquática é uma modalidade de hidroterapia realizada em recém-nascidos (RN) nas Unidades de Terapia Intensiva Neonatal (UTIN). Os efeitos sobre nível de dor, estado comportamental e função respiratória já são conhecidos, porém pouco se refere aos efeitos sobre a função diafragmática na população recém-nascida a termo prematura. OBJETIVO: Avaliar o efeito da fisioterapia aquática sobre a amplitude diafragmática por meio da ultrassonografia cinesiológica diafragmática (USCD) em RNs internados em UTIN, bem como a segurança de sua realização quanto a estabilidade clínica dos RNs, estado comportamental, dor e desconforto respiratório. MÉTODOS: Ensaio clínico tipo antes e depois, de caráter transversal. Os RNs participantes do estudo receberam uma única intervenção com fisioterapia aquática durante 10 minutos. Foi realizada a avaliação utilizando a USCD antes e depois da sessão, e anotado as frequências cardíaca e respiratória, estado comportamental, dor e desconforto respiratório. RESULTADOS: Participaram 26 RNs. Observou-se aumento significativo da amplitude diafragmática (p= 0,02) e da saturação periférica de oxigênio (p= 0,05); os parâmetros fisiológicos permaneceram nos limites da normalidade e a intervenção não provocou desorganização comportamental, dor ou desconforto respiratório aos RNs. CONCLUSÃO: A fisioterapia aquática promoveu aumento da amplitude diafragmática, sugerindo que esta técnica pode ser utilizada como forma de estimular a contração da musculatura respiratória em RN, além de se mostrar uma técnica segura, pois não gerou instabilidade clínica, desorganização comportamental, dor ou desconforto respiratório aos participantes.
INTRODUCTION: Aquatic physiotherapy is a modality of hydrotherapy performed on newborn babies (NB) in the Neonatal Intensive Care Unit (NICU). The effects on pain levels, behavior, and respiratory function are already known; however, little has been said about the effects on diaphragmatic function in the preterm newborn population. OBJECTIVE: To evaluate the effect of aquatic physiotherapy on diaphragmatic amplitude using diaphragmatic kinesiologic ultrasound (DKUS) in NBs admitted to a NICU, as well as the safety regarding the clinical stability of the NBs, behavioral state, pain, and respiratory distress. METHODS: Crosssectional before-and-after clinical trial. The NBs participating in the study received a single intervention with aquatic physiotherapy for 10 minutes. An assessment was performed using the USCD before and after the session, and heart and respiratory rates, behavioral state, pain, and respiratory discomfort were recorded. RESULTS: Twenty-six NBs participated. There was a significant increase in diaphragmatic amplitude (p= 0.02) and peripheral oxygen saturation (p= 0.05); physiological parameters remained within normal limits, and the intervention did not cause behavioral disorganization, pain, or respiratory discomfort in NBs. CONCLUSION: Aquatic physiotherapy promoted an increase in diaphragmatic amplitude, suggesting that this technique can be used as a way to stimulate the contraction of the respiratory muscles in NB, in addition to being a safe technique, as it did not generate clinical instability, behavioral disorganization, pain, or respiratory discomfort to the participants.

ABSTRACT BACKGROUND AND OBJECTIVES: Healthy newborns inevitably undergo painful procedures from the first hours of life and pain assessment is essential for choosing the right treatment. The objective of this study was to evaluate the agreement between evaluators of the Neonatal Facial Coding System (NFCS) pain scale in healthy newborns before, during and after hepatitis B vaccination performed in the first 48 hours of life. METHODS: This is an analysis of agreement between two evaluators, carried out as part of a quasi-experimental intervention study, developed in a maternity hospital in Belo Horizonte. Two researchers carried out an independent evaluation based on filming 2 minutes before, during and 2 minutes after the procedure. RESULTS: The study included 129 newborns between August and December 2022, 60 (46.51%) in the control group (facilitated restraint) and 69 (53.49%) in the intervention group (breastfeeding). There was substantial agreement between the researchers before (0.69) and after (0.70) vaccination. When the agreement between the groups was analyzed, it was substantial for the evaluations of newborns submitted to facilitated restraint before and after the procedure. In the breastfeeding group, agreement was almost perfect before and substantial after the procedure. CONCLUSION: There was substantial agreement between the researchers who used the NFCS scale before, during and after vaccination. This data validates the use of the scales when assessing the pain of newborns undergoing easy restraint and breastfeeding, even though it is an indirect method of assessment. It is important to highlight the importance of periodic staff training programs for the use of pain assessment scales at bedside.
RESUMO JUSTIFICATIVA E OBJETIVOS: Recém-nascidos saudáveis são submetidos a procedimentos dolorosos desde as primeiras horas de vida e a avaliação da dor é essencial para escolha do tratamento adequado. O objetivo deste estudo foi avaliar a concordância entre pesquisadores da escala Neonatal Facial Coding System (NFCS) antes, durante e após a vacinação contra hepatite B nas primeiras 48 horas de vida de recém-nascidos saudáveis. MÉTODOS: Trata-se de uma análise de concordância entre pesquisadores, realizada como um estudo de intervenção quase-experimental, desenvolvido em uma maternidade pública de Belo Horizonte. Dois pesquisadores procederam a avaliação independente a partir de filmagens 2 minutos antes, durante e 2 minutos após o procedimento. RESULTADOS: Foram incluídos 129 recém-nascidos entre agosto e dezembro de 2022, sendo 60 (46,51%) no grupo controle (contenção facilitada) e 69 (53,49%) no grupo intervenção (amamentação). Observou-se concordância substancial entre os pesquisadores antes (0,69) e após (0,70) a vacinação. Quando analisada concordância entre os grupos, ela foi substancial para as avaliações de recém-nascidos submetidos à contenção facilitada antes e após o procedimento. No grupo submetido à amamentação, a concordância foi quase perfeita antes e substancial depois do procedimento. CONCLUSÃO: Há concordância substancial entre os pesquisadores que utilizaram a escala NFCS antes, durante e após a vacinação. Este dado valida a utilização das escalas durante a avaliação da dor de recém-nascidos submetidos à contenção facilitada e amamentação, mesmo tratando-se de um método indireto de avaliação. É importante destacar a importância de programas periódicos de capacitação da equipe para utilização de escalas de avaliação da dor à beira leito.
RESUMO
ABSTRACT Objective: To describe the incidence and to analyze risk factors associated with cholestasis in neonates with gastroschisis. Methods: This is a retrospective cohort study in a tertiary single center analyzing 181 newborns with gastroschisis between 2009 and 2020. The following risk factors associated with cholestasis were analyzed: gestational age, birth weight, type of gastroschisis, silo closure or immediate closure, days of parenteral nutrition, type of lipid emulsion, days of fasting, days to reach a full diet, days with central venous catheter, presence of infections, and outcomes. Results: Among the 176 patients evaluated, 41 (23.3%) evolved with cholestasis. In the univariate analysis, low birth weight (p=0.023), prematurity (p<0.001), lipid emulsion with medium-chain triglycerides and long-chain triglycerides (p=0.001) and death (p<0.001) were associated with cholestasis. In the multivariate analysis, patients who received lipid emulsion with fish oil instead of medium chain triglycerides/long chain triglycerides (MCT/LCT) emulsion had a lower risk of cholestasis. Conclusions: Our study shows that lipid emulsion with fish oil is associated with a lower risk of cholestasis in neonates with gastroschisis. However, this is a retrospective study and a prospective study should be performed to confirm the results.
RESUMO Objetivo: Analisar a incidência e os fatores de risco associados à colestase em recém-nascidos com gastrosquise. Métodos: Estudo de coorte retrospectivo em um único centro terciário, que analisou 181 recém-nascidos com gastrosquise entre 2009 e 2020. Foram examinados os seguintes fatores de risco associados à colestase: idade gestacional, peso ao nascer, tipo de gastrosquise, fechamento com silo ou fechamento imediato, dias de uso nutrição parenteral, tipo de emulsão lipídica, dias de jejum, dias para atingir a dieta completa, dias com cateter venoso central, presença de infecções e desfechos. Resultados: Dos 176 pacientes avaliados, 41 (23,3%) evoluíram com colestase. Baixo peso ao nascer (p=0,023), prematuridade (p<0,001), emulsão lipídica com triglicerídeos de cadeia média e triglicerídeos de cadeia longa (p=0,001) e óbito (p<0,001) foram associados à colestase. Na análise multivariada, os pacientes que receberam emulsão lipídica com óleo de peixe em vez da emulsão diária de triglicérides de cadeia média/triglicérides de cadeia longa (MCT/LCT) apresentaram menor risco de colestase. Conclusões: Nosso estudo mostra que a emulsão lipídica com óleo de peixe está associada a menor risco de colestase em neonatos com gastrosquise, porém este é um estudo retrospectivo, e um estudo prospectivo deve ser realizado para confirmar os resultados.
