Brief Summary:
To evaluate the diagnostic performance of amylase assay performed from bronchial alveolar fluid to differentiate aseptic chemical inhalation pneumonitis from an infectious inhalation pneumonitis in comatose patients with intubated ventilation for less than 24 hours.

Condition or disease
Infectious Pneumonia Coma

Detailed Description:
Validation of the potential diagnostic performance of amylase assay compared to gold standard in diagnosis of infectious inhalation pneumonia of the comatose patient enabling the realization of a multicentric study using this innovative method in a diagnostic strategy with the objective of reducing the consumption of antibiotics.
