Birth and very low-weight newborn care are nowadays a challenge for perinatology specialists. A retrospective and descriptive study was conducted in all neonates weighing less than 1 000 g at birth seen in Neonatal Care Service of "Mariana Grajales" Teaching Provincial Gynecology and Obstetrics Hospital of Villa aClara province from 2000 to 2008 to describe its behavior from the perinatology point of view, as well as to identify and to relate the maternal and neonatal variables in this weight group and to describe the morbidity and mortality incidence in neonates weighing less than 1 000 g. Thus, we made a documentary observation designing an instrument applied to 24 neonates born during such period. Included are the variable related to perinatal backgrounds, morbidity and mortality yielded the proposed objectives; results are expressed in tables. The very low weight newborn incidence was low (0.,07 % of all the live birth) most of them born before 30 weeks of gestational age (78%) and a frequent weight between 900 and 999 g (67%). These patients had a frequent morbidity: hyaline membrane disease and apnea, systemic infections, severe physiologic icterus, metabolic disorders (hypoglycemia, metabolic acidosis) a low Apgar score at birth and anemia. The 50% of children needed ventilation therapy due to hyaline membrane disease and infections among others; survival was of 70,8% (17 patients) and mortality causes were diverse.
