Morbilidad del recién nacido prematuro tardío durante su primer mes de vida comparado con el recién nacido de término

Introduction: In recent years there has been an increase in the number of births of infants near term; this late prematurity is associated with increased neonatal morbidity and mortality, so it is important to know the differences in morbidity in this group of patients compared with term newborns, during the fi rst month of life. Objective: To evaluate the early morbidity and during the fi rst month of life of late preterm compared with term infants. Material and methods: We performed a comparative study of two cohorts of infants. Cohort 1: Late preterm infants from 34 to 36.6 weeks of gestation and Cohort 2; term infants. The morbidity was recorded during the fi rst month of life, 15 variables were measure. We used descriptive statistic, for comparison between groups Student's t and to compare morbidity between groups the relative risk with 95% confi dence interval. Results: We included 59 late preterm and 69 term infants. Of the maternal factors studied no statistically signifi cant difference was found; respect to neonatal morbidity, we identifi ed a great risk in the late pre- term risk for hyperbilirubinemia (OR 1.7, CI 95% 1.1-2.65), gastroesophageal refl ux (OR 1.8, CI 95% 1.1-289) and feed- ing diffi culties (OR: 1.66, CI 95% 1.14-2.42). Conclusions: The risk of morbidity in late preterm found are those related to their own prematurity. In this study, there was no pathology associated with maternal morbidity in late preterm.
