Аннотация
This study aimed to identify factors associated with neonatal sepsis due to Serratia marcescens in a Neonatal Intensive Care Unit (NICU) in Mexico. A case-control study was conducted, matched by gestational age and birth weight. The analysis was performed using logistic regression. Seventy newborns with S. marcescens sepsis were identified; the median gestational age was 34.4 weeks, and the median birth weight was 1680g. Microbial isolates were identified in the bloodstream in 98.6% of cases, and 88.6% of these were diagnosed after 72h of life. Independent variables associated with infection were the presence of a central venous catheter (OR 5.17; 95% CI 1.57-17.1), mechanical ventilation (OR 3.23; 95% CI 1.18-8.87), and prior use of meropenem (OR 3.38; 95% CI 1.01-11.3). The case fatality rate of the infection was 32.9%.
