%X objective: to evaluate hospital miguel servet perinatal mortality (pm) during the years 2000-2009, valuing its evolution and distribution according to gestational age and birth weight. maternal and fetal possible causes are analized. methods: 44.409 newborns of >500 grams or 22 weeks gestational age, were studied. the total number of perinatal deaths was 402 containing late neonatal deaths (to 28 completed days of live). the data for each case of perinatal mortality were recorded in a form following figo recommendations and the 9th international classification of diseases. results: extended pm rate was 9.05/1000 newborns, fetal mortality 4.91/1000 newborns and neonatal mortality 4.14/1000 live births. standard pm was 4.73/1000 newborns. according to gestational age, 79.60% were preterm deliveries. considering birth weights, 46.02% were extremely low birth weight (<1000 grams), and 59.95% were <1500 grams. the number of perinatal deaths in multiple pregnancies was 92 (90 preterm deliveries). pm in twins was 34.65/1000 newborns. main causes of death were extreme immaturity (<1000 grams) in 46.02%, premature rupture of membranes (23.13%), multiple deliveries (22.89%), complications of placenta or umbilical cord (21.64%), intrauterine hypoxia and asphyxia at birth in 21.64% of the cases, and congenital malformations and chromosomopaties (18.90%). conclusions: pm is encumbered by prematurity, extremely low birth weight and m¨²ltiple pregnancies. decrease of perinatal mortality had occurred mainly at the expense of neonatal mortality.
