Related to hydrothorax: hydropericardium
a pleural effusion containing serous fluid.
increased fluid in the pleural space; can cause shortness of breath by compression of the lung and/or increased intrathoracic pressure resulting in mediastinal shift and increased work of breathing; a transudative effusion has low protein content and is usually due to heart failure, uremia, or hypoalbuminemia; an exudative effusion has high protein and cell count and is due most often to inflammation, malignancy, or infection; an infected pleural effusion is an empyema; a pleural effusion associated with pneumonia is a parapneumonic effusion; a pleural effusion without actual infection but with signs of a high degree of inflammation (for example, low pH, low glucose, high lactate dehydrogenase, many white blood cells) is a complex pleural effusion and is frequently associated with pneumonia; a loculated pleural effusion is not free flowing in the pleural space but rather confined to one or more fixed pockets.
hydrothorax/hy·dro·tho·rax/ (-thor´aks) a pleural effusion containing serous fluid.
Accumulation of serous fluid in one or both pleural cavities.
Etymology: Gk, hydor + thorax, chest
a noninflammatory accumulation of serous fluid in one or both pleural cavities.
Presence of fluid in one or both pleural cavities, usually resulting from cardiac failure.
the presence of noninflammatory serous fluid within the pleural cavity. The fluid in the pleural cavity causes compression of lung with resulting dyspnea and ventral absence of lung sounds.
