Purpose : This study was performed to estimate the incidence of nosocomial sepsis and to identify the most relevant risk factors for nosocomial sepsis in high-risk very low birth weight (VLBW) infants.
Methods : A retrospective review of 341 VLBW infants, admitted to the Neonatal Intensive Care Unit of the Eulji University Hospital (Daejeon & Seoul) between January 2002 and June 2009, who survived more than 72 hours was performed. The incidence, causative organisms, risk factors and prognosis of nosocomial sepsis in VLBW infants were analyzed.
Results : The incidence of nosocomial sepsis was 16.1% and the onset date of nosocomial sepsis was 21.5±15.9 days (mean±SD) after delivery. Staphylococcus aureus (21.3%) was the most common organism in the patients with nosocomial sepsis in VLBW infants. The multiple logistic regression analysis showed that, gestational age [odds ratio (OR), 0.87; 95% CI, 0.83-0.91], umbilical artery catheter use for more than 5 days (OR, 2.2; 95% CI, 1.15-4.46), umbilical venous catheter use for more than 5 days (OR, 2.1; 95% CI, 1.11-4.16), peripheral arterial line use (OR, 2.1; 95% CI, 1.14-4.04) and intravenous intralipids (OR, 4.3; 95% CI, 1.13-14.32) were identified as risk factors.
Conclusion : The limited usage of intravascular catheter related procedures and the short providence of intravenous nutrition may decrease the incidence of nosocomial sepsis in VLBW infants. (J Korean Soc Neonatol 2010;17:84-93)
