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

[Developmental centered care. Evaluation of Spanish neonatal units]. / Cuidados centrados en el desarrollo. Situación en las unidades de neonatología de España.

INTRODUCTION: Developmental and family centered care (DC) is a framework that aims to enhance the neurodevelopment of the infant. Over the last few years Spanish neonatal units have been working toward introducing this type of care. OBJECTIVE: To evaluate DC in Spanish neonatal units by assessing certain features of the care provided to very low birth weight infants and their families. MATERIAL AND METHOD: Spanish hospitals attending infants under 1,500 g were identified. A cross sectional study was performed using a telephone questionnaire with 25 DC-related items. RESULTS: Of the 100 hospitals attending infants under 1,500 g, 83 hospitals from all the Autonomous Communities in Spain participated in the survey. Of these, 31 % had noise pollution controls, 72 % controlled light intensity, 75 % bound the infants, and 29 % used saccharose as an analgesic. Ten percent allowed unrestricted parental visits. Twenty-two percent used kangaroo care without restriction. Sixty-three percent of the units reported difficulties when introducing DC-related changes. CONCLUSIONS: Practically all neonatal units have some type of DC activity, although in certain areas, such as unrestricted parental visits, the rate of implementation is low.
