ABSTRACT

Retinopathy of Prematurity (ROP) significantly contributes to childhood blindness globally, with a disproportionately high burden in low- and middle-income countries (LMICs) due to improved neonatal care alongside inadequate ROP screening and treatment facilities. This study aims to validate the performance of Postnatal Growth and Retinopathy of Prematurity (G-ROP) screening criteria in a cohort of premature infants presenting at a tertiary care setting in Pakistan. This cross-sectional study utilized retrospective chart review of neonates admitted to the neonatal intensive care unit (NICU) at The Aga Khan University Hospital, Pakistan from January 2018 to February 2022. The complete G-ROP criteria were applied as prediction tool for infants with type 1 ROP, type 2 ROP, and no ROP outcomes. Out of the 166 cases, 125 cases were included in the final analysis, and remaining cases were excluded due to incomplete data. ROP of any stage developed in 83 infants (66.4%), of whom 55 (44%) developed type 1 ROP, 28 (22.4%) developed type 2 ROP, and 19 (15.2%) were treated for ROP. The median BW was 1060 gm (IQR = 910 to 1240 gm) and the median gestational age was 29 wk (IQR = 27 to 30 wk). The G-ROP criteria demonstrated a sensitivity of 98.18% (95% CI: 90.28-99.95%) for triggering an alarm for type 1 ROP. The G-ROP criteria achieved 100% sensitivity (95% CI: 87.66 to 100%) for type 2 ROP. The overall sensitivity of G-ROP criteria to trigger an alarm for any type of ROP was 98.8% (95% CI: 93.47 to 99.97%). Thus, the G-ROP screening model is highly sensitive in detecting at-risk infants for ROP in a Pakistani tertiary care setting, supporting its use in LMICs where standard screening criteria may not suffice.

ABSTRACT

OBJECTIVE: To evaluate the rates of exclusive breastfeeding (EBF) and growth of preterm and/or low birth weight newborns during the third stage of the Kangaroo Method (TSKM), at discharge. METHODS: Retrospective study in a reference public maternity hospital between Jan/2014 and Dec/2017, including the preterm (less than 37 weeks) and/or low birth weight (less than 2500 g) newborn infants. Information was collected from medical records. Statistics analysis was done in SPSS software. RESULTS: 482 infants were included and followed up at the TSKM ambulatory. The average gestational age was 33 weeks (variation: 24-39 weeks) and birth weight, 1715g (variation: 455-2830 g). EBF occurred in 336 (70.1%) infants at hospital discharge, and in 291 (60.4%) at TSKM discharge. Each additional day of hospital stay increased the chance of infant formula (IF) use by 9.3% at hospital discharge and by 10.3% at TSKM discharge. Staying in the Kangaroo Neonatal Intermediate Care Unit (KNICU) favored EBF at hospital discharge and TSKM discharge (p<0.001). Not performing the kangaroo position increased the chance formula administration to the newborn infant at hospital discharge by 11%. Weight gain and head circumference growth were higher in infants using formula (p<0.001). CONCLUSIONS: The length of hospital stay and not performing the kangaroo position favored the use of infant formula at hospital and TSKM discharge. Staying in the KNICU favored exclusive breastfeeding at hospital and TSKM discharge. Weight gain and HC growth were higher in newborns receiving infant formula.

ABSTRACT

In preterm infants, early nutrient intake during the first week of life often depends on parenteral nutrition. This study aimed to evaluate the influence of standardized parenteral nutrition using three-in-one double-chamber solutions (3-in-1 STD-PN) on early neonatal growth in a cohort of moderately preterm (MP) infants. This population-based, observational cohort study included preterm infants admitted to neonatal centers in the southeast regional perinatal network in France. During the study period, 315 MP infants with gestational ages between 320/7 and 346/7 weeks who required parenteral nutrition from birth until day-of-life 3 (DoL3) were included; 178 received 3-in-1 STD-PN solution (56.5%). Multivariate regression was used to assess the factors associated with the relative body-weight difference between days 1 and 7 (RBWD DoL1-7). Infants receiving 3-in-1 STD-PN lost 36% less body weight during the first week of life, with median RBWD DoL1-7 of -2.5% vs. -3.9% in infants receiving other PN solutions (p < 0.05). They also received higher parenteral energy and protein intakes during the overall first week, with 85% (p < 0.0001) and 27% (p < 0.0001) more energy and protein on DoL 3. After adjusting for confounding factors, RBWD DoL1-7 was significantly lower in the 3-in-1 STD-NP group than in their counterparts, with beta (standard deviation) = 2.08 (0.91), p = 0.02. The use of 3-in-1 STD-PN provided better energy and protein intake and limited early weight loss in MP infants.

ABSTRACT

BACKGROUND: There is limited evidence regarding the optimal time to commence parenteral nutrition (PN) in term and late preterm infants. DESIGN: Single-centre, non-blinded, exploratory randomised controlled trial. SETTING: A level-3 neonatal unit in a stand-alone paediatric hospital. PATIENTS: Infants born ≥34 weeks of gestation and ≤28 days, who needed PN. Eligible infants were randomised on day 1 or day 2 of admission. INTERVENTIONS: Early (day 1 or day 2 of admission, N=30) or late (day 6 of admission, N=30) PN. MAIN OUTCOME MEASURES: Plasma phenylalanine and F2-isoprostane levels on day 4 and day 8 of admission. Secondary outcomes were amino-acid and fatty-acid profiles on day 4 and day 8, and clinical outcomes. RESULTS: The postnatal age at randomisation was similar between the groups (2.3 (SD 0.8) vs 2.3 (0.7) days, p=0.90). On day 4, phenylalanine levels in early-PN infants were higher than in late-PN (mean (SD) 62.9 (26.7) vs 45.5 (15.3) µmol/L; baseline-adjusted percentage difference 25.8% (95% CI 11.6% to 39.9%), p<0.001). There was no significant difference in phenylalanine levels between the two groups on day 8. There was no significant difference between the groups for F2-isoprostane levels on day 4 (early-PN mean (SD) 389 (176) vs late-PN 419 (291) pg/mL; baseline-adjusted percentage difference: -4.4% (95% CI -21.5% to 12.8%) p=0.62) and day 8 (mean (SD) 305 (125) vs 354 (113) pg/mL; adjusted mean percentage difference -16.1 (95% CI -34.1 to 1.9) p=0.09).Postnatal growth restriction for weight was less severe in the early-PN group (change in weight z-score from baseline to discharge: -0.6 (0.6) vs -1.0 (0.6); p=0.02). The incidence of hyperglycaemia was greater in the early-PN group (20/30 (66.7%) vs 11/30 (36.7%), p=0.02). CONCLUSIONS: The timing of the commencement of PN did not seem to affect the degree of oxidative stress in critically ill term and late preterm infants. The effect of transiently high plasma phenylalanine with early PN on clinical outcomes requires further investigation. TRIAL REGISTRATION NUMBER: ACTRN12620000324910.

ABSTRACT

Taguchi et al. reported that postmenstrual age (PMA) is a promising factor in describing and understanding the developmental change of caffeine (CAF) clearance. The aim of the present study was to quantify how developmental changes occur and to determine the effect of the length of the gestational period on CAF clearance. We performed a nonlinear mixed effect model (NONMEM) analysis and evaluated the fit of six models. A total of 115 samples were obtained from 52 patients with a mean age of 34.3 ± 18.2 d. The median values of gestational age (GA) and postnatal age (PNA) were 196 and 31 d, respectively. Serum CAF levels corrected for dose per body surface area (BSA) (C/D ratioBSA) were dependent on PMA rather than PNA, which supports the findings of a previous study. NONMEM analysis provided the following final model of oral clearance: CL/F = 0.00603∙WT∙∙0.877GA ≤ 196 L/h. This model takes into account developmental changes during prenatal and postnatal periods separately. The model successfully described the variation in clearance of CAF. Our findings suggest that the dosage of CAF in preterm infants should be determined based not only on body weight (WT) but also on both PNA and GA.

ABSTRACT

Human milk oligosaccharides (HMOs) are bioactive factors that benefit neonatal health, but little is known about effects on growth in very preterm infants (<32 weeks' gestation). We aimed to quantify HMO concentrations in human milk fed to very preterm infants during the neonatal hospitalization and investigate associations of HMOs with infant size and body composition at term-equivalent age. In 82 human-milk-fed very preterm infants, we measured HMO concentrations at two time points. We measured anthropometrics and body composition with air displacement plethysmography at term-equivalent age. We calculated means of individual and total HMOs, constructed tertiles of mean HMO concentrations, and assessed differences in outcomes comparing infants in the highest and intermediate tertiles with the lowest tertile using linear mixed effects models, adjusted for potential confounders. The mean (SD) infant gestational age was 28.2 (2.2) weeks, and birthweight was 1063 (386) grams. Exposure to the highest (vs. lowest) tertile of HMO concentrations was not associated with anthropometric or body composition z-scores at term-corrected age. Exposure to the intermediate (vs. lowest) tertile of 3FL was associated with a greater head circumference z-score (0.61, 95% CI 0.15, 1.07). Overall, the results do not support that higher HMO intakes influence growth outcomes in this very preterm cohort.

ABSTRACT

An exclusive human milk diet (EHMD) and standardized feeding protocols are two critical methods for safely feeding very low birth weight (VLBW) infants. Our institution initiated a standardized feeding protocol for all VLBW infants in 2018. In this protocol, a human milk fat modular was used only reactively when an infant had poor weight gain, fluid restriction, or hypoglycemia. As part of our NICU quality improvement program, internal utilization review data revealed a potential opportunity to improve growth and reduce costs. While maintaining the EHMD, a simple feeding guideline process change could provide cost savings without sacrificing caloric density or growth. We examined this process change in pre-post cohorts of VLBW infants. METHODS: Our revised feeding protocol, established in October 2021, called for a human milk fat modular (Prolact CR) to be added to all infant feeding when parenteral nutrition (PN) and lipids were discontinued. The human milk fat modular concentration is 4 mL per 100 mL feed, providing approximately an additional 2 kcal/oz. We tracked data to compare (1) the use of the human milk fat modular, (2) the use of the human milk +8 fortifier, (3) overall growth before and after feeding protocol changes, and (4) cost differences between protocols. RESULTS: Thirty-six VLBW infants were followed prospectively upon the introduction of the revised feeding protocol. In the revised era, the need for human milk +8 fortifier decreased from 43% to 14%. The decrease in the cost of a more costly fortifier provided a cost savings of USD 2967.78 on average per infant. Overall growth improved from birth to discharge, with severe malnutrition declining from 3.3% to 2.7% and moderate malnutrition declining from 37% to 8%. CONCLUSIONS: With the proactive use of a human milk fat modular in a standardized feeding protocol, our VLBW infants showed improved growth, lower malnutrition rates, and decreased use of higher caloric fortifiers.

ABSTRACT

Infants born low birth weight (LBW) and preterm are at risk for developmental delay and cognitive deficits. These deficits can lead to lifelong learning difficulties and high-risk behaviors. Preterm (PT) and full-term (FT) groups were compared across infant and toddler measures of behavior and development to extract early indicators of executive function (EF). The goal was to extract indicators of EF from standardized infant assessments. PT (<2500 grams and <37 weeks) and FT (> 2500 grams and >37 weeks) were compared across assessment and EF components were identified from the BSID-III. A multivariate linear model was used to examine group differences. All children (99 PT and 46 FT) were administered the Bayley III and the DMQ assessments for session 1 (6-8 months). During session 2, N=78 PT and 37 FT (18-20 months), the CBCL was added to previous assessments, and the BRIEF-P was added to previous assessments in session 3, N= 52 PT and 36 FT for session 3 (See Table 1). Significant change scores were found on BSID-III subtests and EF components across all 3 sessions. The PT group also showed significantly more behavioral concerns on the CBCL at 18 months and 36 months and had lower scores on the BRIEF-P than their FT peers. The number of children born PT (N = 27, 52%) who were in Early Intervention (EI) increased across the 3 sessions. Examining early indicators of EFs supported the development of early identification that could lead to decrease adverse outcomes often associated with preterm birth.

ABSTRACT

BACKGROUND: Breast milk contains various crucial nutrients and biologically active substances and is ideal for newborns. This study aimed to analyze the composition of breast milk from mothers of premature and full-term infants and its influences on the growth of infants. METHODS: Infant-mother dyads examined at our Hospital (March 2016 to May 2017) were included. Milk was collected at 0-1 month, 2-3 months, and 5-6 months and analyzed using a MIRIS human milk analyzer. Z-scores of weight-for-length (WLZ), weight-for-age (WAZ), and length-for-age (LAZ) were calculated. RESULTS: This study included full-term (> 37 weeks of gestation, n = 177) and premature (< 37 weeks, n = 94) infant-mother dyads. The premature infants showed higher ΔWAZ, ΔLAZ, and ΔWLZ from infancy to toddlerhood for the physical growth speed, compared with term infants (P < 0.001). All proteins and true protein components of breast milk decreased with infants' age (P < 0.001). For premature and full-term infants, differences in ΔWAZ and ΔLAZ from birth to infancy and the difference in ΔLAZ, WAZ, and LAZ in toddlerhood were positively associated with non-protein nitrogen (NPN) (all P < 0.05), while the Z-score differences in ΔWLZ from birth to infancy were negatively associated with NPN (all P < 0.05). For premature babies, from birth to infancy stage, ΔWAZ was positively correlated with NPN and carbohydrates while negatively correlated with dry matter (all P < 0.05), and ΔLAZ correlated with NPN (ß = 0.428, P = 0.005). CONCLUSION: Breastfeeding helped premature infants compensatory growth when compared to term infants. Whileduring early infancy stage ΔWLZ gain was negatively associated with increased amounts of NPN in breast milk. This might mean although NPN increase the Z-scores of weight-for-age and length-for-age, with no rise in adipose tissue mass.

ABSTRACT

Background: Human milk (HM) is usually fortified using standard fortification (STD) to improve nutrition of preterm infants. However, the protein component may still be insufficient. HM could be further fortified with additional protein to improve STD. Objective: The primary objective was to compare changes in body weight (g/day, g/kg/day), length, and head circumference (mm/day) between preterm neonates fed HM with STD and those fed HM with adjustable fortification (ADJ). Methods: This study was a prospective, single-blinded, randomized controlled study in preterm infants of gestational age <32 weeks and weighing ≤1,800 g, admitted to the neonatal unit of the Queen Sirikit National Institute of Child Health. Once the infants received full HM feed with STD at 24 kcal/oz, they were randomized to either continue with STD or with ADJ group by adding additional protein to the STD and making further protein adjustments based on the blood urea nitrogen levels. Results: Thirty preterm infants completed the study and were randomized into two groups of 15 each. The baseline characteristics, total fluid, and energy intake were similar. Compared with the STD group, infants in the ADJ group exhibited significantly greater weight gain (36.46 ± 6.09 vs. 25.78 ± 8.81 g/day; p = 0.001) and greater length gain (1.93 ± 0.57 vs. 1.12 ± 0.64 mm/day; p = 0.001). Protein intake significantly correlated with both weight (r = 0.632, p < 0.001) and length gain (r = 0.577, p = 0.001); however, no correlation was found between energy intake, volume intake, and growth outcomes. Conclusion: Preterm infants fed with ADJ had significantly higher weight and length gains than those fed with STD, suggesting that additional protein intake may play an important role in growth.

ABSTRACT

AIM: We developed the Promotion of Breastfeeding (PROBREAST) programme and evaluated what effect it had on the breastfeeding rate in infants born at less than 32 weeks of gestation or weighing ≤1500 grams. METHODS: We compared the breastfeeding rate in two cohorts of patients who were born before (n = 72; January 2017 to June 2018) and after (n = 80; July 2018 to December 2019) the application of the programme. Moreover, we compared the correlation between type of feeding at discharge and post-discharge breastfeeding rate, between exclusive breastfeeding, postnatal growth and neurodevelopment. RESULTS: Infants in the PROBREAST group had an exclusive breastfeeding rate at discharge higher (42 vs. 16%, p < 0.001) than that in the historical control group. Exclusive breastfeeding was negatively correlated with weight z-score at discharge, but not at 12 and 24 months corrected age, and was positively correlated with cognitive score at 24 months corrected age. CONCLUSION: The application of a structured programme for the promotion of breastfeeding improved the breastfeeding rate in very preterm infants. We demonstrated that exclusive breastfeeding at discharge improved their neurodevelopment without impairing growth.

ABSTRACT

BACKGROUND: Pituitary gland height reflects secretory activity of the hypothalamo-pituitary axis. OBJECTIVE: To assess the cumulative impact of fetal growth and sex on pituitary gland height in premature twins, dissociated from prematurity. MATERIALS AND METHODS: A retrospective study was conducted, assessing the pituitary gland height in 63 pairs of preterm twins, measured from T1-weighted magnetic resonance imaging (MRI). Auxological parameters, including body weight, body length, and head circumference, at birth and at the time of MRI, were used as proxies for fetal and postnatal growth, respectively. The study population was divided into two groups, using corrected age at around term equivalent as the cutoff point. Statistical analysis was performed using mixed-effects linear regression models. RESULTS: When pituitary gland height was evaluated at around term equivalent, a greater pituitary gland height, suggesting a more immature hypothamo-pituitary axis, was associated with the twin exhibiting lower auxological data at birth. The same association was observed when body weight and length at MRI were used as covariants. In the group evaluated after term equivalent, a smaller pituitary gland height, suggesting a more mature hypothamo-pituitary axis, was associated with male sex. This difference was observed in twin pairs with higher average body weight at birth, and in babies exhibiting higher auxological data at MRI. CONCLUSION: After isolating the effect of prematurity, at around term equivalent, pituitary gland height reflects the cumulative impact of fetal growth on the hypothalamo-pituitary axis. Subsequently, pituitary gland height shows effects of sex and of fetal and postnatal growth.

ABSTRACT

Individuals born preterm present lower exercise capacity. Along with the cardiopulmonary responses and activity level, muscle strength is a key determinant of exercise capacity. This systematic review aimed to summarize the current knowledge on the impact of preterm birth on skeletal muscle mass and function across the lifespan. The databases PubMed, MEDLINE, EBM, Embase, CINAHL Plus, Global Index Medicus, and Google Scholar were searched using keywords and MeSH terms related to skeletal muscle, preterm birth, and low birth weight. Two independent reviewers undertook study selection, data extraction, and quality appraisal using Covidence review management. Data were pooled to estimate the prematurity effect on muscle mass and function using the R software. From 4378 studies retrieved, 132 were full-text reviewed and 25 met the inclusion/exclusion criteria. Five studies presented a low risk of bias, and 5 had a higher risk of bias due to a lack of adjustment for confounding factors and presenting incomplete outcomes. Meta-analyses of pooled data from homogenous studies indicated a significant reduction in muscle thickness and jump test (muscle power) in individuals born preterm versus full-term with standardized mean difference and confidence interval of - 0.58 (0.27, 0.89) and - 0.45 (0.21, 0.69), respectively.    Conclusion: Overall, this systematic review summarizing the existing literature on the impact of preterm birth on skeletal muscle indicates emerging evidence that individuals born preterm, display alteration in the development of their skeletal muscle mass and function. This work also highlights a clear knowledge gap in understanding the effect of preterm birth on skeletal muscle development. What is Known: • Preterm birth, which occurs at a critical time of skeletal muscle development and maturation, impairs the development of different organs and tissues leading to a higher risk of comorbidities such as cardiovascular diseases. • Preterm birth is associated with reduced exercise capacity. What is New: • Individuals born preterm display alterations in muscle mass and function compared to individuals born at term from infancy to adulthood. • There is a need to develop preventive or curative interventions to improve skeletal muscle health in preterm-born individuals.

ABSTRACT

BACKGROUND: Preterm, low-birth weight (LBW) and small-for-gestational age (SGA) newborns have a higher frequency of adverse health outcomes, including linear and ponderal growth impairment. OBJECTIVE: To describe the growth trajectories and to estimate catch-up growth during the first 5 y of life of small newborns according to 3 vulnerability phenotypes (preterm, LBW, SGA). METHODS: Longitudinal study using linked data from the 100 Million Brazilian Cohort baseline, the Brazilian National Live Birth System (SINASC), and the Food and Nutrition Surveillance System (SISVAN) from 2011 to 2017. We estimated the length/height-for-age (L/HAZ) and weight-for-age z-score (WAZ) trajectories from children of 6-59 mo using the linear mixed model for each vulnerable newborn phenotype. Growth velocity for both L/HAZ and WAZ was calculated considering the change (Δ) in the mean z-score between 2 time points. Catch-up growth was defined as a change in z-score > 0.67 at any time during follow-up. RESULTS: We analyzed 2,021,998 live born children and 8,726,599 observations. The prevalence of at least one of the vulnerable phenotypes was 16.7% and 0.6% were simultaneously preterm, LBW, and SGA. For those born at term, all phenotypes had a period of growth recovery from 12 mo. For preterm infants, the onset of L/HAZ growth recovery started later at 24 mo and the growth trajectories appear to be lower than those born at term, a condition aggravated among children with the 3 phenotypes. Preterm and female infants seem to experience slower growth recovery than those born at term and males. The catch-up growth occurs at 24-59 mo for males preterm: preterm + AGA + NBW (Δ = 0.80), preterm + AGA + LBW (Δ = 0.88), and preterm + SGA + LBW (Δ = 1.08); and among females: term + SGA + NBW (Δ = 0.69), term + AGA + LBW (Δ = 0.72), term + SGA + LBW (Δ = 0.77), preterm + AGA + LBW (Δ = 0.68), and preterm + SGA + LBW (Δ = 0.83). CONCLUSIONS: Children born preterm seem to reach L/HAZ and WAZ growth trajectories lower than those attained by children born at term, a condition aggravated among the most vulnerable.

O percentual médio de creme foi de 3,84±1,3% e mediana de 4,5 % no leite pasteurizado, e no cru de 8,9±4,6% e 8,53%. A média e mediana do conteúdo energético do leite cru foi de 78,91±15,46 kcal/100 ml e 81,07 kcal/100 ml e no leite pasteurizado 65,18±9,67 kcal/ 100 ml e 61,8 kcal/100 ml. Conclusão: o leite humano cru possui percentual de gordura e conteúdo energético maior do que o pasteurizado, mas este ainda é recomendado devido seus benefícios protetores.


Objective: to evaluate and compare the energy content of raw human milk and processed human milk from preterm newborns. Method: 68 milk samples were collected by hand milking and processing was carried out at the Human Milk Bank. The energy value was obtained through specific mathematical calculations. Results: 32 samples of raw human milk and 28 of pasteurized human milk were analyzed. The average percentage of cream was 3.84±1.3% and a median of 4.5% in pasteurized milk, and in raw milk, 8.9±4.6% and 8.53%. The mean and median energy content of raw milk was 78.91±15.46 kcal/100 ml and 81.07 kcal/100 ml and in pasteurized milk 65.18 ± 9.67 kcal/100 ml and 61.8 kcal/100 ml. Conclusion: raw human milk has a higher percentage of fat and energy content than pasteurized milk, but it is still recommended due to its protective benefits.


Objetivo: evaluar y comparar el contenido energético de la leche humana cruda y la leche humana procesada de recién nacidos prematuros. Método: Se recolectaron 68 muestras de leche por ordeño manual y el procesamiento se realizó en el Banco de Leche Humana. El valor energético se obtuvo mediante cálculos matemáticos específicos. Resultados: se analizaron 32 muestras de leche humana cruda y 28 de leche humana pasteurizada. El porcentaje medio de nata fue 3,84±1,3% y una mediana de 4,5% en leche pasteurizada, y en leche cruda 8,9±4,6% y 8,53%. El contenido energético medio y mediano de la leche cruda fue de 78,91±15,46 kcal/100 ml y 81,07 kcal/100 ml y de la leche pasteurizada de 65,18±9,67 kcal/100 ml y 61,8 kcal/100 ml. Conclusión: la leche humana cruda tiene un mayor porcentaje de contenido graso y energético que la leche pasteurizada, pero aun así es recomendada por sus beneficios protectores.

ABSTRACT

A evolução científica e tecnológica na área de enfermagem, tem ganho um destaque no cuidado ao recém-nascido, sendo que nas unidades de cuidados intensivos neonatais se tem assistido a uma mudança de cultura na promoção de cuidados holísticos e de intervenções neuroprotetoras. Apesar dos avanços científicos e tecnológicos os recém-nascidos pré-termo mantêm-se vulneráveis às consequências da prematuridade, nomeadamente no que diz respeito à otimização da nutrição. Um dos desafios dos enfermeiros é potenciar o desenvolvimento de competências do RN na transição para a alimentação oral, de forma segura e eficaz, promovendo a autonomia alimentar. O presente Relatório de Estágio pretende evidenciar o desenvolvimento e aquisição das competências de Enfermeiro Especialista em Enfermagem de Saúde Infantil e Pediátrica durante o percurso de formação, sob a temática escolhida: promoção das competências alimentares no recém-nascido. O processo formativo foi suportado numa metodologia crítica e reflexiva, baseada na evidência científica e no Modelo de Sistemas de Betty Neuman, enquanto referencial teórico de enfermagem, nos Cuidados Centrados na Família e nos Cuidados Não Traumáticos enquanto pilares de enfermagem pediátrica e ainda no modelo dos Cuidados para o Desenvolvimento, baseados na Teoria Sinativa de Desenvolvimento de Als. Das atividades desenvolvidas destacam-se a realização de duas sessões de formação sobre as competências alimentares do recém-nascido e a apresentação a escala de avaliação das competências oromotoras através da escala Early Feeding Skills Versão Modificada.


The scientific and technological development in nursing has gained prominence in newborn care and neonatal intensive care units have witnessed a change of culture in the promotion of holistic care and neuroprotective interventions. Despite scientific and technological advances, preterm newborns remain vulnerable to the consequences of prematurity, particularly regarding the optimisation of nutrition. One of the main challenges nurses face is to promote the development of the newborn's skills in the transition to oral feeding, by safely and effectively promoting feeding autonomy. This Report aims to highlight the development and acquisition of skills as Specialist Nurse in Child Health and Paediatric Nursing, during the reflective practice, under the main problematic: promotion of feeding skills in newborns. This learning process is based on a critical and reflective methodology, supported by scientific evidence and Betty Neuman's Systems Model, as a nursing theoretical framework. It is also sustained by Family Centred Care and Non-Trauma Care, as pillars of paediatric nursing, and backed by Developmental Care Model, based on Als´s Synactive Theory of development. Among the activities developed, two training sessions stand out regarding the feeding skills of the newborn and the presentation of oromotor skills, using the Early Feeding Skills Modified Version asessment scale.

ABSTRACT

Uruguay acompaña la tendencia mundial al descenso de la natalidad con un descenso de la mortalidad concomitante, siendo la primera causa de mortalidad infantil la prematurez. Enfocados en la prematurez, es de nuestro interés conocer qué ocurre con estos niños luego del alta de la unidad neonatal. Se realizó el estudio de una cohorte de niños entre 4 y 8 años, nacidos con 32 semanas o menos de edad gestacional y/o con pesos al nacer de 1.500 g o menos, asistidos en su período neonatal en la Asociación Médica de San José, a quienes se les realizó el test de Battelle. Se logró identificar las áreas con mayor dificultad en el desarrollo para cada grupo de edad, concluyendo que se pueden realizar planes específicos de acción para promover el desarrollo de estos niños en la edad preescolar y escolar.


Uruguay follows the global declining trend in birth rates along with decreasing mortality, being prematurity the main cause of infant mortality. We studied premature children who had undergone the Battelle Test and had been discharged from the neonatal unit, a cohort of children between 4 and 8 years of age, born at 32 weeks or less of gestational age and/or having a birth weight of 1500g or less, assisted in their neonatal period at the San José Department Medical Center. We could identify the main areas affecting development for each age group, and concluded that specific action plans can be carried out to promote the development of these children at preschool and school age.


O Uruguai acompanha a tendência mundial de declínio das taxas de natalidade com uma concomitante diminuição da mortalidade, sendo a prematuridade a principal causa de mortalidade infantil. Nos focamos na prematuridade e no estudo do que acontece com essas crianças após a alta da unidade neonatal. Realizamos um estudo de uma coorte de crianças entre 4 e 8 anos que tinham sido submetidas ao Teste de Battelle, nascidas com 32 semanas ou menos de idade gestacional e/ou com peso de nascimento igual ou inferior a 1500g, atendidas no período neonatal na Assistência Médica do Departamento de São José no Uruguai. Foi possível identificar as áreas de maior dificuldade de desenvolvimento para cada faixa etária, e concluir que podem se realizar planos de ação específicos para promover o desenvolvimento dessas crianças em idade pré-escolar e escolar.
