Recomendaciones de seguimiento del prematuro tardío / Follow-up recommendations for the late preterm infant

La población de prematuros tardíos (PT), aquellos nacidos entre las 340 y 366 semanas de gestación, representa el 70-74% de todos los prematuros, y no está incluida de forma específica en la mayoría de los protocolos de seguimiento para niños prematuros. Durante muchos años los PT han sido manejados como si de recién nacidos a término se tratasen, lo que ha llevado al desconocimiento de su evolución a medio y largo plazo. A la morbilidad neonatal se añade una mayor incidencia de afección posnatal, con una tasa de reingresos hospitalarios por malnutrición, hiperbilirrubinemia y problemas respiratorios superior a los nacidos a término. La inmadurez cerebral puede ser el principal responsable de los déficits observados en el neurodesarrollo a largo plazo en esta población y aumentar su vulnerabilidad. Se describen retrasos o discapacidades en la etapa preescolar, parálisis cerebral, retraso mental, discapacidad intelectual, esquizofrenia, trastornos del desarrollo psicológico, la conducta y la emoción. El grupo SEN34-36 de la Sociedad Española de Neonatología, en colaboración con la Asociación Española de Pediatría de Atención Primaria, han desarrollado estas recomendaciones de seguimiento con el objetivo principal de disminuir el impacto de la prematuridad en el desarrollo de los PT. Los objetivos secundarios del documento son sensibilizar a neonatólogos y pediatras de los posibles riesgos de secuelas de los PT, determinar y unificar las evaluaciones y/o intervenciones que deberían realizarse, ofrecer herramientas de seguimiento clínico para detectar de manera precoz los déficits en el desarrollo y coordinar la atención de todos los profesionales implicados

The population of late preterm infants (PT), those born between 34 + 0 and 36 + 6 weeks of gestation, accounts for 70-74% of all premature infants, and is not specifically included in most of the follow-up protocols for preterm infants. For many years, PTs have been handled as if they were term newborns, which has led to a limited knowledge of their outcome in the medium and long term. Their neonatal morbidity is associated with a higher incidence of postnatal complications, with an increased rate of hospital re-admissions due to malnutrition, hyperbilirubinaemia, and respiratory problems, when compared to term infants. Cerebral immaturity may be the main cause of the deficits observed in the long-term neurodevelopment of this population, making them more vulnerable. Several issues have been described, such as delays or disabilities in the pre-school stage, cerebral palsy, mental retardation, intellectual disability, schizophrenia, and psychological development of behavioural and emotional disorders. The SEN34-36 Group of the Spanish Society of Neonatology, in collaboration with the Spanish Association of Primary Care Paediatrics, have developed these follow-up recommendations with the main objective of reducing the impact of prematurity on PT development. The secondary objectives of the document are to make neonatologists and paediatricians aware of the risks of sequelae of PTs, to determine and unify the evaluations and / or interventions that should be carried out, to offer clinical follow-up tools for the early detection of developmental delays, and to coordinate the care by all the professionals involved

Recomendaciones de seguimiento del prematuro tardío / Recommendations for the follow-up of the late preterm infant

La prematuridad continúa siendo la primera causa de morbimortalidad neonatal e infantil y constituye uno de los problemas de salud más importantes, sobre todo en la sociedad industrializada. La población de prematuros tardíos, que incluye a los niños nacidos entre las 340 y 366 semanas de edad gestacional, representa el 70-74% de todos los prematuros. Los prematuros tardíos presentan mayor incidencia de patología comparados con los recién nacidos a término y no solo en el periodo neonatal sino también durante la infancia, con unas mayores tasas de rehospitalización y consulta a los servicios de urgencias, un mayor riesgo de infecciones, de fallo de medro, de problemas respiratorios y de trastornos del neurodesarrollo. Nuestro objetivo debe ser poder realizar diagnósticos e intervenciones precoces, principalmente a nivel del neurodesarrollo, que multiplicarán la probabilidad de buena evolución. En esta línea, desde el grupo de trabajo SEN34-36 de la Sociedad Española de Neonatología, en colaboración con la Asociación Española de Pediatría de Atención Primaria, se ha desarrollado este documento de Recomendaciones de seguimiento del prematuro tardío, con el objetivo de sensibilizar a pediatras y neonatólogos de las patologías en las que los prematuros tardíos presentan mayor riesgo y sobre las que debemos focalizar nuestra atención, facilitando una guía de trabajo a los profesionales implicados en el seguimiento de este grupo de prematuros

Prematurity continues to be the leading cause of neonatal and infant morbidity and mortality and stands as one of the most important health problems, especially in industrialized countries. Late preterm infants are those born between 34 and 36 weeks of gestational age and represent 70-74% of all premature births. Late preterm infants show a higher incidence of pathology compared to term infant and not only in the neonatal period but also during childhood, with higher rates of hospital readmissions and visits to emergency services, an increased risk of infections, of failure to thrive, respiratory problems and neurodevelopmental disorders. Our objective will be to anticipate diagnoses and apply early interventions, mainly at the level of neurodevelopment, which will increase the likelihood of better outcomes. In this line, from the working group SEN34-36 of the Spanish Society of Neonatology and in collaboration with the Spanish Association of Pediatrics of Primary Care, this document of Recommendations for the follow-up of the late preterm infant has been edited in order to raise awareness among pediatricians and neonatologists about the most common pathologies in these babies, and on which we must focus our attention, thereby providing a working guide to the professionals involved in the follow-up of this group of premature infants
