Evaluation Of Pneumonia Due To Mechanical Ventilation And Its Association With The Severity Of The Disease In Patients Admitted To Intensive Care Unit
Pneumonia Due To Mechanical Ventilation
Sažetak
Abstract
Context: Among the hospital-acquired infections, pneumonia due to mechanical ventilation (VAP) has the highest mortality and morbidity rates. Aim: The aim of this study was to determine the VAP in the intensive care unit (ICU) and its association with the severity of the disease.
Setting and Design: This descriptive-analytic study was conducted in Golestan University of Medical Sciences (Northern Iran). Materials and Methods: In the present study, 239 patients with mechanical ventilation hospitalized in ICU were selected through non-random sampling. Data were recorded by using APACHE II criteria and diagnosis of VAP was made based on clinical criterion and physician confirmation. Statistical Analysis Used: Data were analyzed by independent t-test, Chi-square, Mann Whitney, and single-variable logistic test. Results: The incidence of VAP was 19.2% and significantly related to mean arterial pressure (P=0.035) and male sex (P=0.122). There was a significant and direct correlation between the incidence of VAP and the increase in the number of gastric residual volume >200 ml (P=0.001). Conclusion: The findings of this study showed gender male, increased arterial pressure and gastric residual volume were the risk factors for developing VAP.
