thoracentesis procedure nursingThoracentesis is the aspiration of fluid from the chest or pleural cavity. It is done for therapeutic and diagnostic purposes. It is therapeutic for patients with hydrothorax when absorption of fluid fails, also for patients with dyspnea and pain resulting from accumulation of fluids and lastly to introduce medications.
