[Diagnostic procedures in artificially ventilated patients with pneumonia].
Pneumonia is a common complication in patients requiring mechanical ventilation and the mortality is high. The diagnosis is difficult to establish in spite of many available diagnostic techniques: Aspiration from endotracheal tube or tracheostomy, fiberbronchoscopy with bronchial aspiration, protected specimen-brush (PSB), bronchoalveolar lavage (BAL), transbronchial biopsy or percutaneous lung needle aspiration or open lung biopsy. A review of the literature is given. It is concluded that PSB and BAL combined with quantitative cultures are valid tools, but there is no conclusion as to the superiority of one over the other. With the use of prior antibiotics the rate of false negatives increases and the specificity and sensitivity are lowered. However, we do need a prospective, randomized trial in order to demonstrate that invasive methods in fact decrease morbidity and mortality in the patients compared with clinical judgement alone.
