INTRODUCTION. At the "Iván Portuondo" Teaching General Hospital (Havana province) maternity is the provincial reference center of newborns care weighing under 1 500 g who accounted for a lowest percentage of all births, but its contribution to morbidity and mortality is high. Thus, the aim of present study was to know the survival of these children for past 11 years. METHODS. A descriptive, cross-sectional and retrospective study was conducted in 19 519 live births including a sample of 78 premature newborns weighing under 1 500 g and a gestational age lower than 37 weeks, born in hospital between 1998 and 2008. We took into account the gestational age, weight, sex, type of delivery, as well as the disease present. Statistic tables were designed whose analysis was performed by percentages. RESULTS. In this stage 19 519 neonates were delivered and from these 1 123 were of low weight including 78 immature newborns (0,4% of total of live births). From the total of immature newborns 12 deceased for a survival of 84,6%. Survival increased in so far as the weight and the gestational age were greater. In cesarean section delivery survival was of 92,7% and in general it was greater in female sex (90,2%). The 80,8% of study children had some associated disease with predominance of asphyxia and hyaline membrane with the 93,3% and the 84,0% survival, respectively. CONCLUSIONS. Survival of newborn weighing under 1 500 g was very good. Leading death causes were hyaline membrane disease and intraventricular hemorrhage. The 80,8% of patients had immature state-associated diseases.
