TO STUDY PROFILE OF PATIENTS WITH PLEURAL EFFUSION AT TERTIARY CARE CENTRE.

Abstract

Pleural effusion is the condition characterized by an abnormal collection of uid in pleural space resulting from excess uid production or decreased absorption(1–3). It is due to pleural uid accumulation inside pleural space. The major mechanism include: increased interstitial uid in the lungssecondary to increased pulmonary capillary pressure (i.e., heart failure) or permeability (i.e., pneumonia); decreased intrapleural pressure (i.e., atelectasis); decreased plasma oncotic pressure (i.e., hypoalbuminemia); increased pleural membrane permeability and obstructed lymphatic ow (e.g., pleural malignancy or infection); diaphragmatic defects (i.e., hepatic hydrothorax); and thoracic duct rupture (i.e., chylothorax)(4).
