Comparison of blind endotracheal aspiration and bronchoscopic brush biopsy sampling methods for bacteriological diagnosis of ventilator-associated pneumonia in intensive care unit

Further confirmation of the diagnosis of VAP can be done by other diagnostic procedures such as bronchoscopic and blind endotracheal aspiration, but the selection of either diagnostic procedure is debatable.
