We aimed to evaluate and compare the viscocity of the exudative pleural fluid according to Light criteria, in patients with pulmonary infection and malignant pulmonary neoplasm.
MATERIALS AND METHODS:
Patients were divided into two groups: group I consisted of 15 patients with pulmonary infection( 5 tuberculosis pleurisy, 10 pneumoniae) and pleural effusion and group II consisted of 18 patients with malignant pulmonary neoplasm and pleural effusion. Measurements of pleural fluid viscocity were performed using Brookfield DW-II viscometer.
Viscocity of the pleural fluid in patients with pulmonary infection was significantly higher than in those with malignant pulmonary neoplasm (1.57±0.85 mPa vs 1.2±0.9mPa respectively p<0.001).
We have shown increased viscosity of pleural fluid in patients with pulmonary infection compared to patients with malignant pulmonary neoplasm. With the support of furhter clinical studies, viscosity of the pleural fluid can be used in differential diagnosis of exudative pleural effusion.
