ABSTRACT

Introducción: Los recién nacidos pretérminos tardíos (RNPT-T) son los neonatos nacidos entre las 34 y 36 semanas de edad gestacional. Debido a su incremento es importante conocer el comportamiento de los mismos, a fin de adecuar el manejo y seguimiento posteriores al alta. Este estudio describe la morbimortalidad, mortalidad, síndrome de dificultad respiratoria (SDR), ictericia, dificultad en la alimentación e hipoglucemia asociada a los RNPT-T en comparación con los RNT. Población y métodos: Estudio de cohortes retrospectivo. Se incluyeron 500 RN entre 34 a 36,6 semanas (RNPT-T) y 500 entre 37-41,6 semanas (RNT) de edad gestacional nacidos en el HMI "Ramón Sardá" de Buenos Aires entre 2007 y 2008. Resultados: Los RNPT-T presentaron significativamente mayor mortalidad que los RNT (2,9‰ vs. 0,49‰ respectivamente (RR 4,1 IC 95% 3,2-15,7) y morbilidad, representada por mayor SDR, ictericia, dificultad en la alimentación, internación prolongada e hipoglucemias. Conclusión: Los recién nacidos pretérminos tardíos presentan mayor mortalidad y morbilidades que los recién nacidos de termino.


Introduction: Late preterm infants are the infants born between 34 and 36 weeks of gestational age. Because of the increase is important to know their behavior in order to adapt the management and follow-up after discharge. We described in this study the morbidity associated with late preterm infants compared to term infants, determine the incidence of complications often presented such as respiratory distress syndrome (RDS), jaundice, feeding difficulty, hypoglycemia, and death in comparison with infants of =37 weeks gestation age. Population and methods: Retrospective cohort study of infants from 34 to 36.6 weeks gestational age (M=500) born in the "Ramón Sardá" Maternity Hospital during 2007 and 2008. Results: We found that PNB-T had significantly higher mortality compared with the term infants (2.9‰ vs.0.49 ‰, RR 4.1 95% CI 3.2 - 15.7). RDS, jaundice, feeding difficulty, prolonged and major hypoglycemia were higher in the study group. Conclusion: Late preterm infants have higher mortality and morbidity than term infants.
