Background. Preterm birth is currently the leading obstetric problem, affecting between 5 and 12% of all births. The aim of this study was to determine the incidence of prematurity and major causes of morbidity and mortality in preterm infants in the Irapuato General Hospital. Methods. Retrospective study analyzing the clinical records of preterm infants from 2011-2012. Results. There were 10,532 births registered; 736 (6.9%) were premature and of these 472 were admitted to the Neonatal Intensive Care Unit, corresponding to 64% of premature births and 4.4% of all births. An increase was shown in cases of prematurity during the year 2011 (n =206) compared to the year 2012 (n =266). The main causes of admission were hyaline membrane disease, 248 cases (52.5%); septicemia, 12 cases (12.7%) and asphyxia, 43 cases (9.1%). The main causes of neonatal death were sepsis (n =12, 32.4%), respiratory distress syndrome (n =8, 21.6%) and congenital heart disease (n =4, 10.8%). Neonatal mortality rate was 3.5. Conclusions. The incidence of prematurity increased from 6.5% in 2011 to 7.4% in 2012. We must identify the risk factors in order to establish preventive measures.
