INTRODUCTION:Pleural involvement is common in various respiratory diseases including inflammatory, infectious, occupational or neoplastic entities. Pleural effusions are a common medical problem and are occasionally intractable. In order to determine the etiology of pleural effusions, it has been widely recommended to assess the appearance of pleural fluid at thoracentesis. Bloody pleural effusions are associated particularly with malignant aetiologies. Pleural fluid analysis is the key component in the diagnosis and management of pleural effusion. Etiology of bloody pleural effusion not only encompasses malignancy but also a diverse set of other clinical entities.
AIMS AND OBJECTIVES:• Categorize bloody pleural fluid into blood-tinged, haemorrhagic effusions and hemothorax based on pleural fluid haematocrit • To record their frequency in relation to diagnosis and to evaluate its cause.
MATERIAL AND METHODS:The patients who attended the Department of Pulmonary Medicine, V.S.S.M.C.H, Burla during the period of October 2009 to September 2011 were included in this study. RESULTS: In our study all 70 patients with bloody pleural effusion was taken and pleural fluid analysis revealed that the maximum number of patients i.e., 65 (92.85 %) had their pleural fluid protein levels in the exudative range (i.e,≥3.5gm%), remaining 5(7.14%) had in the transudative range (i.e.,≤3gm%). The examination of pleural fluid cytology showed predominantly lymphocytes in 37 (52.85%), RBCs °enerated polymorhonuclear cells in 19 (27.14%), macrophages & mesothelial cells in 6(8.57%), eosinophils in 2(2.85%) & neutrophils in 1(1.42%).Malignant cells were found in the pleural fluid in 11 (15.71%). Malignancy was proved by CT guided FNAC in 10(14.28%) subjects. Bloody pleural effusion due to infection was

Parasitic aetiology was identified to be due to Entamoeba histolytica in all 3 cases. CONCLUSION: Majority of bloody pleural effusions of infective etiology were caused by tuberculosis, followed by parasitic and bacterial infections. By malignancy, primary site of which was found to be in lung, followed by undiagnosed primary, breast, ovary, oral and Non-Hodgkin's lymphoma in the order of frequency. The second common presentation was blood-tinged effusion caused by traumatic tap or due to thickened pleura. KEYWORDS: Pleural effusions; Hemothorax, Thoracentesis, Haemorrhagic pleural effusion
INTRODUCTION:Pleural effusion is accumulation of excessive pleural fluid in pleural space. Several mechanisms underlying pleural effusion include increased permeability of the pleural membrane, increased pulmonary capillary pressure, decreased negative intrapleural pressure, decreased oncotic pressure, and obstructed lymphatic flow. Bloody pleural effusions are a common occurrence...
