Abstract:
The aim of the study was to evaluate the prevalence and the risk factors of ventilation-associated pneumonia (VAP) for out-of-hospital or in the emergency department intubated patients. This was a retrospective descriptive study. All intubated adults subsequently admitted to the ICU over 1-year period were included. Among 75 patients, 15 patients developed VAP (20%; 95% CI 12-31%). A multivariate analysis revealed three variables independently associated with VAP: cardiorespiratory arrest as the reason of intubation (P=0.001), out-of-hospital as the location of intubation (P=0.011), and clinical macroaspiration as clinical characteristic at the time of intubation (P=0.024). Death rate was 17% and was not significantly higher for patients with VAP (P=0.9; 95% CI 0.32-4.95%). Emergency care workers should be aware of the potential 20% occurrence of VAP when they intubate and ventilate a patient. Preventive strategies, which have been proven effective in ICUs, should be implemented in the emergency setting.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
