Abstract

Objective: to assess the characteristics of ventilator-associated pneumonia (VAP) and determine the bacterial causes of VAP. Subjects and methods: Cross-sectional descriptive study included 269 patients with endotracheal tube (or tracheostomy) mechanically ventilated for more than 48 hours from January 1, 2022 to December 31, 2022 at the Intensive Care Department of Ha Tinh Provincial General Hospital. Results: VAP accounted for 35.5% with an incidence of 44.35 patients/1000 days of mechanical ventilation. The average age of patients with VAP was 72 ± 13.6 years old, with late-onset VAP accounting for a high rate (60%). Patients with VAP mostly presented high fever, leukocytosis, and increased procalcitonin. In particular, signs of rapid breathing, rales in the lungs and increased secretion of sputum were presented in 100% of patients. The etiologies of VAP were mainly gram-negative bacteria, with the most common was Acinetobacter baumanni (53.7%), followed by Klebsiella pneumonia (23.2%). The mortality rate from VAP remains high. Conclusion: The study revealed the incidence, characteristics and bacterial causes of ventilator-associated pneumonia in the Intensive Care Department of Ha Tinh Provincial General Hospital
