Prevalencia de osteopenia del prematuro antes y después de la implementación de una estrategia temprana de manejo fosfocálcico / Prevalence of osteopenia of prematurity before and after implementing an early strategy with the use of calcium and phosphate

Introducción. Con el uso de la nutrición parenteral agresiva en recién nacidos de muy bajo peso, se detectaron alteraciones del metabolismo fosfocálcico. En 2016 se implementó una estrategia de prevención a través del monitoreo fosfocálcico y su suplementación temprana. El objetivo fue estudiar si esta estrategia disminuye la prevalencia de osteopenia e identificar factores de riesgo asociados. Población y métodos. Estudio cuasiexperimental que comparó la prevalencia de osteopenia entre dos grupos: uno después de implementar la estrategia de monitoreo y suplementación fosfocálcica (01/01/2017-31/12/2019), y otro previo a dicha intervención (01/01/2013-31/12/2015). Resultados. Se incluyeron 226 pacientes: 133 pertenecen al período preintervención y 93 al posintervención. La prevalencia de osteopenia global fue del 26,1 % (IC95% 20,5-32,3) y disminuyó del 29,3 % (IC95% 21,7-37,8) en el período preintervención al 21,5 % (IC95% 13,6-31,2) en el posintervención, sin significancia estadística (p = 0,19). En el análisis multivariado, el puntaje NEOCOSUR de riesgo de muerte al nacer, recibir corticoides posnatales y el período de intervención se asociaron de manera independiente a osteopenia. Haber nacido luego de la intervención disminuyó un 71 % la probabilidad de presentar fosfatasa alcalina >500 UI/L independientemente de las restantes variables incluidas en el modelo. Conclusión. La monitorización y suplementación fosfocálcica precoz constituye un factor protector para el desarrollo de osteopenia en recién nacidos con muy bajo peso al nacer.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017­12/31/2019) and another prior to such intervention (01/01/2013­12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5­32.3) and it was reduced from 29.3% (95% CI: 21.7­37.8) in the pre-intervention period to 21.5% (95% CI: 13.6­31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants.

Potenciales evocados auditivos de tronco en neonatos nacidos a gran altitud / Brainstem auditory evoked potentials in newborn infants born in a high-altitude area

Introducción. Una forma no invasiva y segura de evaluar los parámetros neurofisiológicos en recién nacidos es la evaluación de los potenciales evocados auditivos del tronco encefálico (PEAT). Objetivo. Evaluar las latencias e intervalos de ondas de los PEAT en neonatos sanos nacidos a gran altitud (Cusco, 3399 msnm). Población y métodos. Estudio transversal y prospectivo. Se incluyeron neonatos menores a 14 días de vida, dados de alta a menos de 7 días de nacidos, evaluados para determinar los valores de los PEAT a intensidades sonoras de 70 dB, 80 dB y 90 dB. Se incluyeron las variables edad gestacional, peso al nacer, tipo de parto. Se calcularon las diferencias de las medianas de las latencias e intervalos de las ondas según edad gestacional y peso al nacer. Resultados. Se evaluaron 96 neonatos (17 pretérminos). Las medianas de las latencias de las ondas I a V a 90 dB fueron las siguientes: onda I 1,56 ms; onda II 2,74 ms; onda III 4,37 ms; onda IV 5,62 ms, onda V 6,63 ms. La latencia de la onda I para 80 dB fue de 1,71 ms y para 70 dB de 1,88 ms. Los intervalos para las ondas (I-III), (III-V) y (I-V) fueron de 2,8 ms, 2,2 ms y 5,0 ms respectivamente, sin diferencias entre intensidades (p >0,05). La prematuridad y el bajo peso estuvieron asociados a latencias de la onda I más prolongadas (p <0,05). Conclusiones. Se presentan valores ajustados de latencias e intervalos de los PEAT en neonatos nacidos a gran altitud. Se identificó que, a distintas intensidades sonoras, se ven diferencias en las latencias de las ondas, pero no en los intervalos entre ondas.

Introduction. A non-invasive and safe way to assess neurophysiological parameters in newborn infants is the evaluation of brainstem auditory evoked potentials (BAEPs). Objective. To assess the latencies and wave intervals of BAEPs in healthy newborn infants born in a high-altitude area (Cusco, 3399 MASL). Population and methods. Cross-sectional and prospective study. Newborn infants younger than 14 days of age, discharged less than 7 days after birth, were assessed to determine BAEP values at intensities of 70 dB, 80 dB, and 90 dB. The study variables were gestational age, birth weight, and type of delivery. The median differences in wave latencies and intervals were estimated according to gestational age and birth weight. Results. A total of 96 newborn infants (17 preterm infants) were assessed. The median latencies of waves I­V at 90 dB were for wave I: 1.56 ms, wave II: 2,74 ms, wave III: 4.37 ms, wave IV: 5.62 ms, and wave V: 6.63 ms. The latency of wave I for 80 dB was 1.71 ms and for 70 dB, 1.88 ms. Wave intervals (I­III, III­V, I­V) were 2.8 ms, 2.2 ms, and 5.0 ms, respectively, without differences among intensities (p > 0.05). Prematurity and low birth weight were associated with a longer wave I latency (p < 0.05). Conclusions. Here we describe adjusted BAEP latency and interval values for newborn infants born at high altitude. At different sound intensities, we identified differences in wave latencies, but not in interwave intervals.

Evaluación del valor de acidez Dornic de la leche humana según el tiempo de conservación en freezer y el lugar de extracción / Assessment of Dornic acidity in breast milk based on storage time in the freezer and place of expression

Introducción. El grado de acidez Dornic (AD), medida indirecta del grado de contaminación de la leche humana cruda (LHC), proporciona información sobre la calidad de esta. Recién extraída, el valor oscila entre 1,0° y 4,0° (óptimo). Descalifica el consumo si es >8,0 °D. Se evaluó la correlación de la AD de la LHC de donantes internas (DI) y externas (DE) según el tiempo de conservación hasta la pasteurización, y se determinó la prevalencia de AD ≤4 ºD. Población y método. Estudio retrospectivo analítico. Resultados. Sobre 13 203 muestras, la AD a partir del día 14 de conservación fue menor en las donantes internas, de 2,92; (IC95% 2,69-3,15) versus 4,01 (IC95%: 3,94-4,08); p <0,001] con mayor proporción de AD ≤4 ºD (88 % en DI versus 76 % en DE); OR: 2,30 (IC95%: 1,25-4,24); p = 0,003. Coeficiente de correlación para las DI: R 2 :0; p = 1). Conclusión. La AD a partir del día 14 fue menor en DI, presentando mayor prevalencia de AD ≤ 4ºD. No existió correlación entre el tiempo de conservación y la AD en las DI.

Introduction. The degree of Dornic acidity (DA) is an indirect measure of milk contamination and quality. In freshly expressed milk, DA ranges between 1.0 and 4.0 (optimal). If DA is > 8.0 °D, it should be discarded. The correlation between DA in raw breast milk from internal donors (ID) and external donors (ED) based on storage time until pasteurization was assessed. Population and method. Retrospective, analytical study. Results. In 13 203 samples, DA was lower in IDs as of 14 days of storage: 2.92 (95% CI: 2.69­3.15) versus 4.01 (95% CI: 3.94­4.08), with a higher proportion of DA ≤ 4 °D (88% in IDs versus 76% in EDs); odds ratio: 2.30 (95% CI: 1.25­4.24). Conclusion. DA as of 14 days of storage was lower in IDs, with a higher prevalence of DA ≤ 4 °D. No correlation was observed between storage time and DA in ID samples.

Hematological disorders in preterm newborns born to mothers with pregnancy-induced hypertension / Alteraciones hematológicas en recién nacidos pretérmino de madres con enfermedad hipertensiva del embarazo

Abstract Background: Pregnancy-induced hypertension (PIH) has been related to impaired fetal growth, possibly by affecting hematopoiesis. This study aimed to analyze the most frequent hematological alterations in preterm infants born to mothers with PIH. Methods: We conducted a cross-sectional study in newborns born to mothers with PIH. We reviewed 130 hemograms of preterm infants: 45 from mothers with PIH, 71 with preeclampsia, and 14 with HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count). Normality, cytosis conditions, or cytopenia values were adjusted for gestational ages. Differences between groups were analyzed with classical and Bayesian statistics (BF01 = null/alternative hypothesis ratio). Results: Anemia was found in only 1.2% of newborns. In the white blood cell count, the most frequent finding was lymphopenia (56.2%) and monocytosis (38.5%) (p = 0.6, FB01 = 249 y p = 0.81, FB01 = 19.9). Thrombocytopenia was found in 12.5% (p = 0.56, FB01 = 67). No significant differences were observed among PIH groups. Conclusions: Hematological alterations of newborns born to mothers with PIH are frequent and do not show a distinct pattern related to the severity of the affection in the mother. We recommend a full hematological evaluation in these preterm neonates.

Resumen Introducción: La enfermedad hipertensiva del embarazo (EHE) se ha relacionado con alteraciones en el crecimiento fetal, posiblemente porque afecta la hematopoyesis. El objetivo de este estudio fue analizar las alteraciones hematológicas más frecuentes en los recién nacidos prematuros hijos de madres con EHE. Métodos: Se llevó a cabo un estudio transversal en recién nacidos de madres con EHE. Se revisaron los hemogramas de 130 neonatos prematuros: 45 madres con hipertensión gestacional, 71 con pre-eclampsia y 14 con síndrome de HELLP (hemólisis, enzimas hepáticas elevadas y bajo recuento de plaquetas). Las cifras de normalidad, condiciones de citosis o citopenia fueron ajustadas a las edades gestacionales. Las diferencias entre los grupos se analizaron con estadística clásica y bayesiana (FB01= relación hipótesis nula/alterna). Resultados: Se encontró anemia en solo el 1.2% de los recién nacidos. En la serie blanca el hallazgo más frecuente fue la linfopenia (56.2%) y monocitosis (38.5%) (p = 0.6, FB01 = 249 y p = 0.81, FB01 = 19.9). La plaquetopenia se encontró en el 12.5% (p = 0.56, FB01 = 67). No se observaron diferencias significativas entre los grupos de EHE. Conclusiones: Las alteraciones hematológicas en recién nacidos de madres con EHE son frecuentes sin mostrar un patrón distinto con relación a la gravedad del padecimiento de la madre. Aun así, es recomendable la valoración hematológica en estos neonatos.

Frequency of maternal stress and psychic risk in newborns who have been hospitalized in a neonatal intensive care unit / Frequência de estresse materno e de risco psíquico em recém-nascidos que foram hospitalizados em unidade de terapia intensiva neonatal

Abstract Objectives: describe the frequency of maternal stress and psychic risk indicators in newborns who were exposed to the neonatal intensive care unit (NICU) after hospital discharge. Methods: observational, analytical, cohort study, sample of 26 participants (13 exposed and 13 not exposed to the NICU). Maternal stress was assessed by Inventário de Sintomas de Stress para Adultos de Lipp (ISSL) (Lipp's Stress Symptoms Inventory for Adults) and psychological risk by Indicadores Clínicos de Risco para o Desenvolvimento Infantil (IRDI) (Clinical Risk Indicators for Child Development), 15 days after hospital discharge and at 4 months of corrected age. Results: the study found a frequency of stress of 23.1% in mothers of newborns who were exposed to NICUs and 38.5% of psychological risk in these newborns. The following associations were found: maternal stress and newborn exposure to the NICU (p=0.037); maternal stress and newborn exposure time to NICU (p=0.031); psychological risk and prematurity (p=0.014). There were no association between psychic risk and maternal stress; and there was no diference in the frequency of psychological risk between the groups of newborns. Conclusions: newborn hospitalization in the NICU is associated with maternal stress, but not with psychological risk. Prematurity can cause psychological risk. Maternal stress was not associated with psychological risk.

Resumo Objetivos: descrever a frequência de estresse materno e indicadores de risco psíquico em recém-nascidos que foram expostos à unidade de terapia intensiva neonatal (UTIN). Métodos: estudo observacional, analítico, coorte, amostra de 26 participantes (13 expostos e 13 não expostos a UTIN). O estresse materno foi avaliado pelo Inventário de Sintomas de Stress para Adultos de Lipp e o risco psíquico pelo IRDI (Indicadores Clínicos de Risco para o Desenvolvimento Infantil), 15 dias após a alta hospitalar e aos quatro meses de idade corrigida. Resultados: o estudo encontrou frequência de estresse de 23,1% nas mães de RN que foram expostos a UTIN e 38,5% de risco psíquico nestes bebês. Encontrou as seguintes associações: estresse materno e exposição do RN à UTIN (p=0,037); estresse materno e tempo de exposição do RN à UTIN (p=0,031); risco psíquico e prematuridade (p=0,014). Não encontrou associação entre risco psíquico e estresse materno; e não encontrou diferença na frequência de risco psíquico entre os grupos de RN. Conclusões: a internação do RN em UTIN está associada a estresse materno, mas não a risco psíquico. A prematuridade pode causar risco psíquico. O estresse materno não apresentou associação com risco psíquico.

Introducción. La mortalidad de los recién nacidos de muy bajo peso de nacimiento (RNMBPN) se ha mantenido en ~26 % en los últimos 16 años en la Red Neonatal NEOCOSUR. Objetivo. Determinar la causa de muerte de los RNMBPN y su temporalidad en el período 20072016 en la Red Neonatal NEOCOSUR. Población y métodos. Estudio observacional de cohorte multicéntrica; análisis retrospectivo de datos obtenidos prospectivamente. Se incluyeron recién nacidos entre 24 y 31+6 semanas de edad gestacional y peso de nacimiento de 500-1500 g, en 26 centros de la Red Neonatal NEOCOSUR. Las causas de muerte se analizaron según ocurriera en sala de partos (SP) o durante la estadía en la unidad de cuidados intensivos neonatales (UCIN). La edad posnatal de muerte se determinó a través de análisis de Kaplan-Meier. Resultados. Se incluyeron un total de 11.753 RNMBPN con una mortalidad global del 25,6 %. Las causas de muerte predominantes en SP fueron malformaciones congénitas (43,3 %), enfermedades respiratorias (14,3 %) y prematuridad (11,4 %). Las causas de muerte predominantes en UCIN fueron las respiratorias (24,2 %) e infecciosas (24,1 %). La edad promedio de muerte fue de 10,2 días y mediana de 4 días. El 10,2 % de las muertes ocurrieron en SP; el 21,5 %, durante el primer día; el 52 % ocurrió en los primeros 4 días y el 63,8 %, durante la primera semana de vida. Conclusiones. Se encuentran importantes diferencias en las causas de muerte de RNMBPN según ocurra en SP o en UCIN. Las infecciosas y respiratorias son las más relevantes luego del ingreso a la unidad de cuidados intensivos.

Introduction. Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network. Objective. To determine the cause of death of VLBWIs and its temporality in the 2007-2016 period in the NEOCOSUR Neonatal Network. Population and methods. Observational, multicenter cohort study; retrospective analysis of data collected prospectively. Newborn infants born between 24 and 31+6 weeks of gestation age with a birth weight between 500 and 1500 g in the 26 sites of the NEOCOSUR Neonatal Network were included. The causes of death were analyzed depending on whether they occurred in the delivery room (DR) or in the neonatal intensive care unit (NICU). The postnatal age at time of death was determined using the KaplanMeier test. Results. A total of 11 753 VLBWIs were included; overall mortality was 25.6%. The prevailing causes of death in the DR were congenital malformations (43.3%), respiratory diseases (14.3%), and prematurity (11.4%). The prevailing causes of death in the NICU were respiratory diseases (24.2%) and infections (24.1%). The average and median age at death were 10.2 and 4 days, respectively. Also, 10.2% of deaths occurred in the DR; 21.5% on day 1, 52% in the first 4 days, and 63.8% in the first week of life. Conclusions. Important differences were observed in the causes of death of VLBWIs depending on their occurrence in the DR or the NICU. Infectious and respiratory conditions were the most relevant factors following admission to the NICU.

Prematurity and functional gastrointestinal disorders in infancy: a cross-sectional study

ABSTRACT BACKGROUND: Functional gastrointestinal disorders (FGIDs) are defined as a variable combination of chronic or recurrent gastrointestinal symptoms that are not explained by structural or biochemical abnormalities. Their relationship with prematurity has been increasingly studied. OBJECTIVE: To compare the frequency of FGIDs in preterm and term infants and to evaluate whether invasive procedures during the neonatal period in preterm infants are associated with greater likelihood of FGIDs in the first two years of life. DESIGN AND SETTING: Controlled nested cross-sectional study conducted in a Brazilian university hospital. METHODS: This was a controlled nested cross-sectional study on a retrospective cohort of infants born preterm who were compared with infants born at term regarding the presence of FGIDs. Medical consultations were conducted by a single pediatric gastroenterologist to obtain information on the gestational and neonatal periods and on clinical manifestations of the digestive tract. The Rome IV criteria for the diagnosis of FGIDs were used. RESULTS: A total of 197 infants (< 24 months), including 99 preterm and 98 term infants, were studied. Infant regurgitation was more prevalent in term infants (35.1% and 15.6%; P < 0.001). The frequencies of other FGIDs (infant colic, functional constipation, functional diarrhea and infant dyschezia) in preterm infants did not differ from those of term infants (P > 0.05). No relationship was found between invasive procedures during the neonatal period and development of FGIDs in preterm infants. CONCLUSION: Infants born preterm did not have higher frequency of FGIDs in the first two years of life.

Understanding the impact of newborn touch upon mothers of hospitalized preterm neonates

Introduction: Many interventions have been designed to support the development of the preterm baby and minimise the complications of prematurity. However, there is limited evidence of the possible psychological benefits of touch to the mother when she is the one performing the support programme during the hospitalisation of her newborn. Objective: This study explored whether the type of touch provided to preterm neonates had an impact on maternal self-efficacy, self-esteem and maternal-to-infant attachment, as-well-as newborn weight gain. Methods: Using a randomised cluster trial, forty babies and their mothers were allocated to one of two groups receiving either a touch-based intervention (TAC-TIC; Touching And Caressing; Tender In Caring) or spontaneous touch. Results: Mothers who provided the touch-based intervention demonstrated greater increases in self-efficacy, self-esteem and attachment, and babies gained more weight than those using spontaneous touch. Conclusion: The results indicate that systematic touch interventions may be used to facilitate the mother-baby relationship as well as to promote newborn weight gain.

Introdução: muitas intervenções têm sido desenhadas para apoiar o desenvolvimento do bebê prematuro e minimizar as complicações da prematuridade. No entanto, são limitadas as evidências dos possíveis benefícios psicológicos do toque para a mãe quando é ela quem realiza o programa de apoio durante a hospitalização de seu recém-nascido.Objetivo: este estudo explorou se o tipo de toque fornecido aos recém-nascidos prematuros teve impacto na autoeficácia materna, autoestima e apego materno-infantil, bem como no ganho de peso do recém-nascido.Método: usando um estudo randomizado de cluster, quarenta bebês e suas mães foram alocados em um dos dois grupos que receberam uma intervenção baseada em toque (TAC-TIC; Tocando e acariciando; Tender In Caring) ou toque espontâneo.Resultados: as mães que forneceram a intervenção baseada no toque demonstraram maiores aumentos na autoeficácia, autoestima e apego, e os bebês ganharam mais peso do que aqueles que usaram o toque espontâneo.Conclusão: os resultados indicam que intervenções sistemáticas de toque podem ser utilizadas para facilitar a relação mãe-bebê, bem como para promover o ganho de peso do recém-nascido.

Cambios en la microbiota intestinal en neonatos pretérmino en un hospital de tercer nivel en Perú / Changes in the intestinal microbiota in preterm infants in a tertiary hospital in Peru

Introducción: La Microbiota Intestinal (MI) del recién nacido pretérmino (RNP) es modificada por factores como la hospitalización, los antibióticos, la nutrición post natal, entre otros. El estudio: Investigación observacional ­ longitudinal con objetivo de analizar los cambios en la MI promovidos por el tipo de lactancia recibida en neonatos <37 semanas de edad gestacional. Se analizaron muestras de 23 neonatos hospitalizados en las Unidades de Cuidados Intensivos (UCIN) y Neonatología. Hallazgos: No se encontró diferencia significativa en el desarrollo de la MI respecto al tipo de alimentación, sin embargo se observó una tendencia diferente entre los neonatos alimentados con Leche Humana (LH) que aumentaron la cantidad de Lactococcus y Clostridium mientras disminuyeron Lactobacillus, opuesto al grupo alimentado con Lactancia Mixta (LM) que aumentó la abundancia de Lactobacillus y disminuyó Lactococcus y Clostridium; Conclusión: Se concluye que los miembros específicos de la MI del RNP depende de la interacción dinámica entre el huésped y el tipo de selección dietética.

Efecto de la velocidad de crecimiento intrahospitalaria en la somatometría a los 2 años en niños con peso de nacimiento menor de 1500 gramos / Effect of intrahospital growth rate on somatometric measurements at 2 years old in children with a birth weight of less than 1500 grams

Objetivo. Determinar la asociación de la velocidad de crecimiento (VC) intrahospitalaria y la fortificación de leche humana con la somatometría y el riesgo de muerte tras el alta o discapacidad grave a los 2 años de edad corregida (EC). Población y método. Análisis retrospectivo de la VC y evolución posterior. Se incluyeron los recién nacidos del período 1990-2015, con peso al nacer < 1500 g. Se excluyeron neonatos con patología que afectaba al crecimiento. Se estudió una cohorte global y dos subcohortes: los nacidos en 1990-2001 (sin fortificación) y los nacidos en 2002-2015 (fortificada). La VC se calculó según la fórmula de Fenton y se consideró adecuada si resultó > 12 g/kg/día. Resultados. Se reclutaron 1194 pacientes. La VC adecuada se asoció a mayor mediana de peso a los 2 años de EC en la cohorte global (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0,02. La cohorte 2002-2015 alcanzó mayor talla media (86,42 ± 4,03 cm versus 85,56 ± 4,01, p = 0,02) y mayor porcentaje de prematuros que alcanzaron un crecimiento compensatorio (catch-up) a los 2 años de EC en la cohorte global con VC adecuada (62,50 % versus 34,69 %, p < 0,02). No se encontraron diferencias en el riesgo de muerte tras el alta o discapacidad grave a los 2 años de EC con VC adecuada (OR: 0,79; IC95 %: 0,47-1,12) ni al considerarse el análisis por subcohortes. Conclusiones. Una VC adecuada se asoció con mejor crecimiento, pero no con menor riesgo de muerte tras el alta o discapacidad grave. La cohorte fortificada alcanzó mayor talla media a los 2 años de EC.

Objective. To determine the association between intrahospital growth rate (GR) and breast milk fortification and somatometry, and risk for death after discharge or severe disability at 2 years of corrected age (CA). Population and method. Retrospective analysis of GR and subsequent course. Infants born in the 1990-2015 period with a birth weight < 1500 g were included. Infants with diseases affecting growth were excluded. An overall cohort and 2 sub-cohorts were studied: infants born in the 1990-2001 period (without fortification) and 2002-2015 period (with fortification). The GR was estimated and deemed adequate if > 12 g/kg/day. Results. A total of 1194 patients were recruited. An adequate GR was associated with a higher median weight at 2 years of CA in the overall cohort (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0.02). The 2002-2015 cohort reached a higher mean height (86.42 ± 4.03 cm versus 85.56 ± 4.01, p = 0.02). More preterm infants caught-up growth at 2 years of CA in the overall cohort with an adequate GR (62.50 % versus 34.69 %, p < 0.02). No differences were observed in the risk for death after discharge or severe disability at 2 years of CA with an adequate GR (OR: 0.79; 95 % confidence interval: 0.47-1.12). Conclusions. An adequate GR was associated with improved growth, but not with a lower risk for death after discharge or severe disability. The cohort with fortified breast milk reached a higher mean height at 2 years of CA

Aleitamento materno exclusivo e estado nutricional de prematuros em unidade de terapia intensiva / Exclusive breastfeeding and nutritional status of preterm in intensive care unit / Amamantamiento materno exclusivo y estado nutricional de prematuros en unidad de terapia intensiva

O leite materno é o alimento mais seguro para o recém-nascido prematuro, que necessita de cuidados especiais, pois contém propriedades imunológicas e nutrientes essenciais em quantidades adequadas. Diante disso, o estudo teve como objetivo investigar a prevalência de consumo de leite materno e estado nutricional entre recém-nascidos prematuros em Unidade de Terapia Intensiva neonatal. Trata-se de um estudo transversal com recém-nascidos prematuros internados em uma Unidade de Terapia Intensiva neonatal. Avaliou-se as características sociodemográficas dos pais e/ou responsáveis, e o estado nutricional e a alimentação dos recém-nascidos por meio de dados dos prontuários. Foram avaliados 56 recém-nascidos prematuros, prevalecendo o sexo feminino, de gestação única (75%), idade gestacional média de 33 semanas, média de peso 1.617,3 gramas. A maioria dos bebês (47%) recebeu aleitamento materno misto (fórmula e leite materno), seguido do aleitamento materno exclusivo (33,3%), e leite artificial (19,6%). Segundo as curvas de INTERGROWTH-21st, constatou-se que maior parte dos prematuros apresentavam peso normal (60,7%), seguido de baixo peso (39,9%). Referente ao perímetro cefálico, houve predomínio de normalidade (58,9%). Em relação à estatura, prevaleceu o comprimento abaixo do normal (57,1%). Com esses dados, ficou constatado que houve prevalência na utilização de aleitamento materno misto para os prematuros internados na Unidade de Terapia Intensiva. Desta forma, entende-se que é importante uma abordagem multiprofissional com intuito de encorajar e incentivar a prática do aleitamento materno exclusivo, e contribuir para apropriada indicação da fórmula, dentro das razões médicas necessárias para o uso de substitutos do leite materno.

The mother milk is the safest food to the preterm newborn, who needs for special care, because it has immunological properties and essential nutrients in adequate quantities. Therefore, the study had as objective to investigate the prevalence of mother milk and nutritional status of preterm newborns in Neonatal Intensive Care Unit. This is a transversal study with preterm newborns hospitalized in a Neonatal Intensive Care Unit. The sociodemographic characteristics of parents or responsible, nutritional status and the newborn feed were evaluated through the data of patient records. Fifty-six preterm newborns were evaluated, prevailing the female sex and of unique gestation (75%), gestational age average of 33 weeks, average weight of 1.617,3 grams. The majority of babies, (47%) received mixed breastfeeding (formula and mother milk), followed by exclusive breastfeeding (33,3%), and artificial milk (19,6%). According to the curves of INTERGROWTH-21st, it was found that the major part of preterm newborns presented normal weight (60,7%), followed by low weight (39,9%). Relating to the head circumference, it was predominance of normality (58,9%). In relation to the structure, prevailed the length below the normal (57,1%). It was prevalence in the use of mixed breastfeeding to the preterm newborns hospitalized in the Intensive Care Unit. In this way, it is understood that is important a multiprofessional approach with the intention of to encourage and stimulate the practice of exclusive breastfeeding, and to contribute to the appropriate indication of formula, within necessary medical reasons to the use of substitutes of breastfeeding.

La leche materna es el alimento más seguro para el recién nacido prematuro, que necesita de cuidados especiales, pues contiene propiedades inmunológicas y nutrientes esenciales en cantidades adecuadas. Ante esto, el estudio tuvo como objetivo investigar la prevalencia de la leche materna y estado nutricional de los recién nacidos prematuros en unidad de terapia intensiva neonatal. Se trata de un estudio transversal con recién nacidos prematuros internados en una Unidad de Terapia Intensiva neonatal. Se evaluaron las características sociodemográficas de los padres y/o responsables, y el estado nutricional y la alimentación de los recién nacidos a través de datos de los prontuarios. Fueron evaluados 56 recién nacidos prematuros, prevaleciendo el sexo femenino, de gestación única (75%), edad gestacional media de 33 semanas, media de peso 1.617,3 gramos. La mayoría de los bebés, (47%) recibieron amamantamiento materno mixto (fórmula y leche materna), seguido de amamantamiento materno exclusivo (33,3%), y leche artificial (19,6%). Según las curvas de INTERGROWTH-21st, se constató que mayor parte de los prematuros presentaban peso normal (60,7%), seguido de bajo peso (39,9%). Referente al perímetro cefálico, hubo predominio de normalidad (58,9%). En relación a la altura, prevaleció el largo abajo de lo normal (57,1%). Hubo prevalencia en la utilización de amamantamiento materno mixto para los prematuros internados en la Unidad de Terapia Intensiva. De esta forma, se entiende que es importante un abordaje multiprofesional con objetivo de encorajar e incentivar la práctica del amamantamiento materno exclusivo, y contribuir a la apropiada indicación de la fórmula, dentro de las razones médicas necesarias para el uso de sustitutos de la leche materna.

RESUMEN Introducción: la reducción del bajo peso al nacer constituye una prioridad en el país por ser determinante para disminuir la mortalidad infantil. Objetivo: determinar los principales factores de riesgo asociados al bajo peso al nacer Guisa, Granma. Métodos: se realizó un estudio descriptivo de corte transversal, incluyó a 37 gestantes que aportaron los nacimientos con bajo peso en el periodo de estudio. Se analizaron las variables edad materna, evaluación nutricional al inicio del embarazo, edad gestacional al momento del parto, tipo de bajo peso, antecedentes personales y enfermedades asociadas al embarazo. Resultados: se produjeron 511 nacimientos, 37 mostraron un peso inferior a 2500 g. El mayor número de nacimientos ocurrió en edades fértiles de la vida, predominando la evaluación nutricional normopeso al inicio del embarazo. La edad gestacional entre 37-42 semanas fueron las que más aportaron bajo peso, no ocurrieron nacimientos en gestantes con menos de 32 semanas. Predominaron los crecimientos intrauterinos restringidos. Entre los antecedentes patológicos resalta, la hipertensión arterial, seguida por el asma bronquial, la anemia ligera. Conclusiones: el bajo peso al nacer es un problema de salud en el municipio Guisa y por consiguiente su influencia negativa sobre la calidad de vida de los infantes. Las edades extremas no resultaron factores de incidencia en el bajo peso al nacer al igual que el estado nutricional. Las principales causales son el crecimiento intrauterino restringido y el parto pretérmino. La identificación precoz de los factores de riesgo y la adopción de medidas efectivas permitirá disminuir la incidencia de estas causas.

ABSTRACT Introduction: reducing low birth weight is a priority in the country as it is decisive for reducing infant mortality. Objective: to determine the main risk factors associated with low birth weight Guisa, Granma. Methods: a descriptive cross-sectional study was carried out, it included 37 pregnant women who provided births with low birth weight in the study period. The variables maternal age, nutritional evaluation at the beginning of pregnancy, gestational age at delivery, type of low weight, personal history and diseases associated with pregnancy were analyzed. Results: there were 511 births, 37 showed a weight less than 2500 g. The highest number of births occurred in fertile ages of life, predominating the normal weight nutritional assessment at the beginning of pregnancy. Gestational ages between 37-42 weeks were the ones that contributed the most to low weight, there were no births in pregnant women with less than 32 weeks. Restricted intrauterine growths predominated. Among the pathological antecedents, arterial hypertension stands out, followed by bronchial asthma, mild anemia. Conclusions: low birth weight is a health problem in the Guisa municipality and therefore its negative influence on the quality of life of infants. Extreme ages were not factors of incidence in low birth weight as well as nutritional status. The main causes are restricted intrauterine growth and preterm delivery. The early identification of risk factors and the adoption of effective measures will reduce the incidence of these causes.

RESUMO Introdução: a redução do baixo peso ao nascer é uma prioridade no país, pois é decisiva para a redução da mortalidade infantil. Objetivo: determinar os principais fatores de risco associados ao baixo peso ao nascer Guisa, Granma. Métodos: foi realizado um estudo transversal descritivo, com 37 gestantes que realizaram partos com baixo peso ao nascer no período do estudo. Foram analisadas as variáveis ​​idade materna, avaliação nutricional no início da gestação, idade gestacional no parto, tipo de baixo peso, antecedentes pessoais e doenças associadas à gravidez. Resultados: ocorreram 511 nascimentos, 37 apresentavam peso inferior a 2.500 g. O maior número de nascimentos ocorreu em idades férteis de vida, predominando a avaliação nutricional de peso normal no início da gestação. As idades gestacionais entre 37-42 semanas foram as que mais contribuíram para o baixo peso, não ocorrendo partos em gestantes com menos de 32 semanas. Predominaram crescimentos intrauterinos restritos. Dentre os antecedentes patológicos, destaca-se a hipertensão arterial, seguida da asma brônquica, anemia leve. Conclusões: o baixo peso ao nascer é um problema de saúde no município de Guisa e, portanto, influencia negativamente na qualidade de vida dos lactentes. As idades extremas não foram fatores de incidência no baixo peso ao nascer, bem como no estado nutricional. As principais causas são o crescimento intrauterino restrito e o parto prematuro. A identificação precoce dos fatores de risco e a adoção de medidas eficazes irão reduzir a incidência dessas causas.

Intervención con probióticos para la prevención de enterocolitis necrotizante en prematuros extremos menores de 1500 gramos o de 32 semanas / Probiotic intervention to prevent necrotizing enterocolitis in extremely preterm infants born before 32 weeks of gestation or with a birth weight of less than 1500 g

Introducción. Existe evidencia del beneficio de los probióticos en prevenir enterocolitis necrotizante en prematuros extremos. Desde 2015, se usa probiótico preventivo en el Servicio de Neonatología, Hospital Hernán Henríquez Aravena, Temuco, Chile.Objetivo. Evaluar el impacto de este probiótico en la incidencia, gravedad, necesidad de terapia quirúrgica y letalidad por enterocolitis necrotizante en prematuros extremos. Pacientes y método. Estudio retrospectivo de cohortes. Datos analizados con Stata. Se aplicó la prueba exacta de Fisher para comparar porcentajes y, para los promedios, la prueba t para varianzas distintas. Los egresados entre 2015 y 2017 recibieron Lactobacillus reuteri Protectis (LRP), dosis única (1 x 108 unidades formadora de colonias) desde los primeros días de vida hasta cumplir las 36 semanas de edad gestacional corregida. Los controles egresados entre 2012 y 2014 no recibieron LRP.Resultados. El 3,45 % de los casos tuvo algún grado de enterocolitis: grado i (el 64 %), ii (el 18 %), iii (el 18 %); requirió cirugía el 18 % y no hubo letalidad. El 3,75 % de los controles históricos presentaron enterocolitis: grado i (el 12 %), ii (el 35 %), iii (el 53 %); el 64,7 % requirió cirugía, y el 47 % falleció. El grupo intervenido presentó grado ii o iii en un 36 %; en el grupo control, la sumatoria de estos estadios fue del 88 %.Conclusión.LRP administrado en dosis única diaria al prematuro extremo no modificó la incidencia de enterocolitis, pero disminuyó su gravedad, la letalidad y necesidad de tratamiento quirúrgico.

Introduction. There is evidence of the beneficial effects of probiotics to prevent necrotizing enterocolitis in extremely preterm infants. Probiotic prevention has been used since 2015 in the Division of Neonatology of Hospital Hernán Henríquez Aravena, Temuco, Chile.Objective. To assess the impact of this probiotic on the incidence, severity, surgical treatment requirement, and fatality rate of necrotizing enterocolitis in extremely preterm infants.Patients and methods. Retrospective, cohort study. Data were analyzed using Stata. Fisher's exact test was used to compare percentages, and the unequal variances t-test, for averages. Infants discharged between 2015 and 2017 received Lactobacillus reuteri Protectis (LRP), in a single dose (1 x 108 colony forming units), since the first days of life until 36 weeks of corrected gestational age. Controls discharged between 2012 and 2014 did not receive LRP.Results. Some degree of enterocolitis was observed in 3.45 % of cases: stage I (64 %), stage II (18 %), stage III (18 %); 18 % required surgery, and there were no deaths. Among historical controls, 3.75 % had enterocolitis: stage I (12 %), stage II (35 %), stage III (53 %); 64.7 % required surgery, and 47 % died. In the intervention group, stage II or III accounted for 36 % of cases, whereas in the control group, for 88 %.Conclusion. Administering a single daily dose of LRP to extremely preterm infants did not affect the incidence of enterocolitis, but reduced its severity, fatality rate, and surgical treatment requiremen

Producción de leche materna y estado emocional en madres de recién nacidos de muy bajo peso / Breast milk production and emotional state in mothers of very low birth weight infants

Introducción. Existe poca evidencia de la influencia de variables emocionales en la lactancia de madres de recién nacidos de muy bajo peso al nacer (RNMBPN). El objetivo de este estudio fue medir la producción de leche materna (PLM) en dos momentos de la internación neonatal y su asociación con los niveles de ansiedad, depresión y autoeficacia en lactancia en madres de RNMBPN.Población y métodos. Estudio prospectivo, observacional, multicéntrico en madres de RNMBPN (500-1500 g), en 9 centros de la Red NEOCOSUR. La PLM se obtuvo midiendo lo extraído por cada madre. Se utilizaron las escalas STAI para ansiedad, BDI para depresión, y, la escala piloto ALMA para autoeficacia. Estas fueron aplicadas a los 14 días de vida y a las 36 semanas posmenstruales. Se registraron, además, las características biosociales de madres y neonatos. Resultados. Participaron 118 madres. La PLM media a los 14 días fue de 169 ml (desvío estándar ­DE­ ± 132,4) y de 285 ml (DE ± 266,9) a las 36 semanas, y se asoció significativamente con percepción de autoeficacia en lactancia (p < 0,001), que se mantuvo durante la hospitalización. Existió una tendencia a menor producción en madres con mayores índices de depresión a los 14 días de vida de su hijo, pero no a las 36 semanas. No se encontró asociación entre PLM y ansiedad. No se encontraron asociaciones consistentemente significativas con variables biosociales. Conclusión. La PLM se asoció positivamente con autoeficacia en lactancia; no se encontró asociación con ansiedad y depresión en madres de RNMBPN

Introduction. There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs.Population and methods. Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for self-efficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded.Results. A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD]: ± 132.4) at 14 days and 285 mL (SD: ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were observed with biosocial variables.Conclusion. BMP was positively associated with breastfeeding self-efficacy; no association was observed with anxiety and depression among mothers of VLBWIs

OBJETIVO: Avaliar os efeitos da musicoterapia nas respostas fisiológicas do recém-nascido pré-termo (RNPT) em ventilação não invasiva. MÉTODO: Estudo quase-experimental, de grupo único, do tipo antes e depois, com trinta prematuros, hospitalizados em uma Unidade de Terapia Intensiva Neonatal. RESULTADOS: Em relação à frequência respiratória (FR), observou-se redução de até seis incursões por minuto (p=<0,001) e em relação à frequência cardíaca (FC), de até sete batimentos por minuto (p=<0,002). Na saturação de oxigênio, identificou-se o aumento em média de 2% (p=0,003). A temperatura axilar apresentou aumento de 0,1ºC após a intervenção (p=0,05). Na escala de dor, identificou-se uma redução de um ponto (p=0,001). DISCUSSÃO: A musicoterapia apresenta efeitos benéficos em relação a redução da FR, da FC e do nível de dor, bem como, aumento da saturação de oxigênio e da temperatura axilar. CONCLUSÃO: A musicoterapia interfere positivamente nas respostas fisiológicas do RNPT em ventilação não invasiva.

OBJECTIVE: To evaluate the effects of music therapy on the physiological responses of preterm newborns (PTNBs) on non-invasive ventilation. METHOD: A quasi-experimental study, with a single group and of the before-and-after type, conducted with thirty premature infants in a Neonatal Intensive Care Unit. RESULTS: As for respiratory frequency (RF), a reduction of up to six breaths per minute was observed (p=<0.001) and, in relation to heart rate (HR), the reduction was up to seven beats per minute (p=<0.002). In oxygen saturation, a 2% (p=0.003) mean increase was identified. Axillary temperature presented a 0.1ºC increase after the intervention (p=0.05). In the pain scale, a one-point reduction (p=0.001) was identified. DISCUSSION: Music therapy presents beneficial effects in relation to reductions in RF, HR and pain level, as well as an increase in oxygen saturation and axillary temperature. CONCLUSION: Music therapy interferes positively with the physiological responses of PTNBs on non-invasive ventilation.

Avaliação do local de nascimento de recém-natos com idade gestacional inferior a 34 semanas segundo complexidade da Unidade Neonatal em maternidades vinculadas à Rede Cegonha: Brasil, 2016-2017 / Evaluation of the birthplace of newborns with gestational age less than 34 weeks according to the complexity of the Neonatal Unit in maternity hospitals linked to the "Rede Cegonha": Brazil, 2016-2017

Resumo O objetivo deste estudo é avaliar o local de nascimento dos prematuros com menos de 34 semanas gestacionais segundo tipo de serviço de assistência neonatal em maternidades da Rede Cegonha, bem como estimar os fatores maternos associados ao local de nascimento não apropriado para idade gestacional. Estudo seccional, de âmbito nacional, realizado em 2016/2017, para avaliação de estabelecimentos com plano de ação da Rede Cegonha. Foram analisadas informações de 303 puérperas e os respectivos locais de ocorrência do parto. Os recém-natos foram classificados segundo a idade gestacional ao nascer (< 30 e 30 a 33 semanas) e os serviços de saúde como unidade de cuidados intensivos neonatais, cuidados intermediários, sem serviço de cuidados neonatais. A portaria ministerial nº 930/2012 foi utilizada para classificar o local de nascimento como apropriado para a idade gestacional do recém-nato. A prevalência de nascimento pré-termo com menos de 30 semanas gestacional foi 37,3 e entre 30 e 33 semanas de 66,8. O nascimento em serviços não apropriado para a idade gestacional do recém-nascido ocorreu em 6,3%, com importantes diferenças regionais e sociais. Apesar dos avanços ainda persistem inequidades no acesso aos cuidados neonatais de prematuros na Rede Cegonha.

Abstract This study aims to evaluate the birthplace of preterm infants with less than 34 gestational weeks at birth by type of neonatal care service in maternity hospitals of the "Rede Cegonha" and estimate the maternal factors associated with the inadequate place of birth for gestational age. This national cross-sectional study was performed in 2016/2017 to evaluate health establishments with the Rede Cegonha's action plan. Information was analyzed from 303 puerperae and the respective health establishments of their births. Newborns were classified by gestational age at birth (<30 and 30-33 weeks) and health establishments as hospitals with neonatal intensive care service, hospitals with intermediate neonatal care service, and hospitals without neonatal care service. Ministerial Ordinance N° 930/2012 was used to classify the birthplace as appropriate for the newborn's gestational age. Preterm birth prevalence was 37.3 at less than 30 weeks' gestation and 66.8 at 30-33 weeks. Birth in inappropriate services for the newborn's gestational age occurred in 6.3%, with significant regional and social differences. Inequalities in access to neonatal care for preterm infants persist in the "Rede Cegonha" despite advances.

Edad gestacional, vía de parto y relación con el día y hora de nacimiento en dos instituciones del sector privado de salud / Gestational age, mode of delivery, and relation to the day and time of birth in two private health care facilities

Introducción. A nivel mundial, hay una tendencia ascendente en nacimientos prematuros y cesáreas. El objetivo fue describir edad gestacional (EG), vía de parto, distribución en días y horarios, y relación entre la vía de parto y el momento del nacimiento en dos instituciones privadas.Población y métodos. Estudio prospectivo, transversal, analítico.Resultados. Se incluyeron los 1500 nacidos vivos entre 9-2017 y 8-2018 (1465 embarazadas). El 99,4 % fueron embarazos controlados; el 66,8 % terminaron por cesárea. La causa fue cesárea previa en el 36,4 %, falta de progresión y descenso en el 18,9 % y elección materna en el 9,2 %. El peso promedio al nacer fue de 3232 g ± 561,1 g y la mediana de EG, 39 semanas (rango 38-40) por fecha de última menstruación. El 88,2 % fueron nacidos de término y, de los prematuros, el 76,1 % fueron pretérminos tardíos. Los nacidos de término temprano tuvieron mayor índice de cesáreas (p < 0,001). Los nacimientos por cesárea en días hábiles fueron 849/1201 (el 74,5 %) y, en los días de fin de semana y feriados, 173/299 (el 57,9 %, p < 0,001). Se encontró una relación estadísticamente significativa entre el horario de nacimiento y la realización de cesárea.Conclusiones. La mediana de EG fue 39 semanas. La cesárea fue la vía de nacimiento más frecuente. Los nacimientos se produjeron, predominantemente, de lunes a viernes entre las 8 y las 21 h. El 82,9 % de los nacimientos por cesárea ocurrieron en días de semana laborables

Introduction. There is a worldwide growing trend of preterm births and C-sections. Our objective was to describe gestational age (GA), mode of delivery, day and time distribution, and the relation between the mode of delivery and the time of birth in two private facilities.Population and methods. Prospective, cross-sectional, analytical study.Results. A total of 1500 live newborn infants were included between September 2017 and August 2018 (1465 pregnant women). Of these, 99.4 % had received antenatal care; 66.8 % of pregnancies ended via C-section. The reason was a previous C-section in 36.4 %, lack of progression and descent in 18.9 %, and maternal choice in 9.2 %. The average birth weight was 3232 g ± 561.1 g and the median GA was 39 weeks (range: 38-40) based on the date of the last menstrual period; 88.2 % were term births and, among preterm births, 76.1 % corresponded to late preterm babies. Early term births showed a higher rate of C-sections (p < 0.001). There were 849/1201 (74.5 %) C-sections on weekdays and 173/299 (57.9 %, p < 0.001) on weekends and holidays. A statistically significant relation was observed between the time of birth and the performance of a C-section.Conclusions. The median GA was 39 weeks.

ABSTRACT Objective: to analyze nurses' perceptions about the feeding of preterm newborns and their motivations in using feeding methods during hospitalization in the neonatology unit. Method: descriptive study with a qualitative approach. Data collection was carried out between July 2019 and January 2020, using semi-structured interviews with 30 nurses from a neonatology unit. The analysis of interview data was carried out using lexicographical textual analysis, the descending hierarchical classification, and similarity analysis through IRaMuTeQ - R Interface software. Results: 876 text segments were analyzed in the descending hierarchical classification, retaining 86.3% of the total for the creation of five classes that resulted from content participation. The similarity analysis of the words representing the nurses' perception about oral feeding and the choice of feeding method led to three central cores, represented by the words: think, give, bottle. Conclusion: Nurses recognize the importance of continuing education and training in the assessment of oral skills. The reason for choosing the feeding method is often based on criteria such as preference, speed, and ease.

RESUMEN Objetivo: analizar la percepción del enfermero sobre la alimentación del recién nacido prematuro y sus motivaciones para aplicación de los métodos de alimentación durante la internación en la unidad de neonatología. Método: estudio descriptivo con abordaje cualitativo. Datos recolectados entre julio de 2019 y enero de 2020, aplicándose entrevista semiestructurada a 30 enfermeros de una unidad de neonatología. El análisis de datos resultante del contenido de las entrevistas se efectuó mediante análisis textual lexicográfico, recurriéndose a la Clasificación Jerárquica Descendente y al análisis de similitud, utilizándose software IRaMuTeQ - Interfaz de R. Resultados: en la Clasificación Jerárquica Descendente fueron analizados 876 segmentos textuales, reteniéndose el 86,3% del total para creación de cinco clases, resultantes de la participación del contenido. El análisis de similitud de palabras representativas de la percepción de los enfermeros sobre alimentación oral y elección del método de alimentación determinó la conformación de tres núcleos centrales, representados por las palabras creer, dar, biberón. Conclusión: los enfermeros reconocen la importancia de la educación continua y de la capacitación en evaluación de las competencias orales. La razón de elección del método de alimentación se fundamenta, frecuentemente, en criterios como preferencia, rapidez y facilidad.

RESUMO Objetivo: analisar a perceção do enfermeiro sobre a alimentação do recém-nascido pré-termo e as suas motivações na aplicação dos métodos de alimentação, durante o internamento na unidade de neonatologia. Método: estudo descritivo, com abordagem qualitativa. Recolha de dados, feita entre julho de 2019 e janeiro de 2020, com recurso à entrevista semiestruturada, a 30 enfermeiros de uma unidade de neonatologia. A análise dos dados que resultaram do conteúdo das entrevistas, fez-se com recurso à análise textual lexicográfica, recorrendo à Classificação Hierárquica Descendente e análise de similitude, através do software IRaMuTeQ - Interface de R. Resultados: na Classificação Hierárquica Descendente, foram analisados 876 segmentos de texto, retendo 86,3% do total para a criação de cinco classes, resultantes da participação do conteúdo. A análise de similitude das palavras representativas da perceção dos enfermeiros, sobre a alimentação oral e a escolha do método de alimentação, conduziu à formação de três núcleos centrais, representados pelas palavras: achar, dar, biberão. Conclusão: os enfermeiros reconhecem a importância da formação contínua e do treino na avaliação das competências orais. O motivo de escolha do método de alimentação baseia-se, frequentemente, em critérios como a preferência, rapidez e facilidade.
