Objectives: To identify the incidence and risk factors of neonatal sepsis in patients born in the General Hospital of Specialties Dr. Javier Buenfil Osorio, during the period from January 2013 to December 2015. Methods: A cross-sectional, retrospective study, observational, descriptive; the record of 106 newborns diagnosed with sepsis were reviewed. We excluded 15 were included in the data collection, diagnosis of early and late neonatal sepsis, maternal age, number of gestation, prenatal care, premature birth, diagnosis of UTI diagnosis of chorioamnionitis, premature rupture of membrane (s RPM ), sex product, invasive procedures, product weight and route of obtaining the product. Results: Of the 1401 patients obtained alive, 191 obtained diagnosis of neonatal sepsis and an incidence of 6.49% of early neonatal sepsis was obtained. The main risk factor associated with early neonatal sepsis has been the way of obtaining caesarean with 52.74%, the low birth weight with 32.96% and multiparity an incidence of 34.06% and there were no significant differences between sexes as the man / femalerelationship was 1.02. However if a significant importance in the delivery / caesarean relationship was obtained0.89. There was only one death recorded. Conclusions: The main risk factors associated with early neonatal sepsis are obtained via caesarean section, low birth weight and multiparity, male sex was the most affected but with no significant differences, the IVU, PROM, maternal age less to 18 years and the lack of prenatal care they had similar incidence. Only one late neonatal sepsis and death was obtained. I do not chorioamnionitis data was obtained.
