ABSTRACT
Background: Ventilator-associated pneumonia (VAP) represents the
second cause of nosocomial infections and it is associated with greater
morbility, duration of mechanical ventilation (MV), and hospital stay. The
objective was to determine factors related with VAP in neonates.
Methods: Analytical transversal study including newborns admitted
already intubated with at least 48 hours of MV or who were intubated in
Neonatal Therapy. VAP was defined according to the criteria of the Centers
for Disease Control and Prevention: “those patients submitted to MV
during at least 48 hours”. We used inferential statistics for statistical analysis
(chi squared, Mann-Whitney
U test, and Kaplan-Meier estimator).
Results: 82 neonates were studied, out of which 27 developed VAP
(33%). The median time to develop pneumonia was 6 days (range 5-11).
The most commonly isolated germ was
Escherichia coli (27%). Statistically
significant variables were gestational age (
p = 0.05), and the use of
antacids at admission (
p = 0.007). Patients with pneumonia had longer
hospital stay (
p = 0.001) and time with MV (
p = 0.002). Of all the patients,
22 neonates died (27%), of which nine patients had VAP.
Conclusion: Risk factors for VAP in neonates include lower gestational
age, the use of antacids, and prolonged MV.
