[Current aspects in the diagnosis of pulmonary infections in intensive care patients].
The diagnosis of pneumonia in the ICU patient is difficult and controversial. Clinical aspects and examination of tracheobronchial secretions are often unhelpful and even misleading. Blood and pleural fluid cultures are not sensitive, while transtracheal or transthoracic aspirations are contraindicated in the ventilated patient. However, quantitative cultures of protected specimen brush samples and bronchoalveolar lavage fluid improve sensitivity and specificity of diagnosis in pulmonary infections in the ICU patient. An easy and rapid aid in differentiating infection from colonization is quantitative analysis of gram-stained specimens of bronchoalveolar lavage fluid.
