Ventilator-Associated Pneumonia in Low Birth Weight Neonates at a Neonatal Intensive Care Unit: A Retrospective Observational Study

摘要

Background: Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections among ventilated patients. The aim of this study was to determine the clinical characteristics and risk factors for the development of VAP in intubated low birth weight (LBW) neonates in a neonatal intensive care unit. Methods: LBW infants ( 48 hours, 15 (13.2%) of whom had VAP. Of these 15 patients, the average age at onset of VAP was 24.0 +/- 11.2 days, the average postmenstrual age was 30.6 +/- 1.8 weeks, and the mean gestational age was 27.1 +/- 2.3 weeks, which was significantly lower than the mean gestational age in the group without VAP (30.2 +/- 3.5 weeks). The mean birth body weight was 944.4 +/- 268.4 g in the VAP group and 1340.1 +/- 455.4 g in the group without VAP (p 48 hours in our neonatal intensive care unit. VAP most frequently occurred at a postmenstrual age of 30-32 weeks in this study. Longer duration of tube placement and parenteral nutrition were found in the VAP group. Early removal of the endotracheal tube and adequate enteral nutrition may decrease the occurrence of VAP in LBW infants.
