ABSTRACT

O acúmulo de líquidos em cavidades fechadas do organismo chama-se derrame cavitário. A efusão pleural é o derrame patológico de líquido na cavidade formada pelas membranas mesoteliais que revestem os pulmões. Causas diversas podem originarestes derrames. Transudatos e exsudatos são classificações preliminares de efusões pleurais de acordo com alguns caracteresfísico-químicos. Transudatos possuem LDH, proteínas e celularidade menores do que os exsudatos. Culturas para anaeróbios, micobactérias e fungos são solicitadas de acordo com a suspeita clínica e epidemiológica. Dosagens bioquímicas e de marcadores tumorais assim como o estudo citológico, microbiológico e de biologia molecular são bastante úteis para o esclarecimento das causas dos derrames pleurais.


The accumulation of fluid in the closed cavities of the body is called spill cavity. The pleural effusion is the pathologicalspill of liquid into the cavity formed by mesotelials membranes, which recover the lungs. Many causes can origin these various spills. Transudates and exudates are preliminary classifications of pleural effusions according to some physical and chemical characteristics. Transudates have LDH, proteins and cellularity lower than the exsudates. Cultures for anaerobics, mycobacteriaand fungi are invited according to epidemiological and clinical suspicion. Biochemical and tumor markers doses rates and so the cytologic study, microbiological study and molecular biology are very helpful to clarify the causes of pleural effusions.
