Management of Bilateral Pleural Effusions

Initial Clinical Assessment

The European Respiratory Society suggests that transudative effusions can often be identified by clinical assessment alone, particularly in the setting of left ventricular failure, cirrhosis, or nephrotic syndrome 1
Clinical indicators of transudates include presence of heart failure with normal-sized heart on chest radiograph, known cirrhosis, or renal failure, as recommended by the European Respiratory Society 1, 2
The American Thoracic Society indicates that all 17 transudates were correctly predicted by clinical assessment without pleural fluid analysis in one series 1

The American College of Chest Physicians recommends performing diagnostic thoracentesis if the patient has bilateral effusions with a normal heart size on chest radiograph 3
The British Thoracic Society suggests performing diagnostic thoracentesis if there are atypical features (unequal effusion size, fever, pleuritic pain, weight loss) 1
The European Respiratory Society recommends performing diagnostic thoracentesis if the effusions fail to respond to appropriate therapy within 48-72 hours 1

The European Respiratory Society recommends treating the underlying medical disorder as the primary approach for transudative effusions 1, 2
For refractory transudative effusions, the European Respiratory Society suggests serial thoracentesis as the preferred first-line approach for symptomatic relief 2
The European Respiratory Society recommends considering pleurodesis only if patients require ≥3 therapeutic thoracenteses and have severe dyspnea 2

The British Thoracic Society recommends observing if asymptomatic or no recurrence after initial thoracentesis 4, 5
The British Thoracic Society suggests seeking specialist opinion from thoracic malignancy multidisciplinary team if symptomatic and recurrent 4, 5
The American Thoracic Society recommends management options in order of consideration, including repeated therapeutic aspiration, chemical pleurodesis, thoracoscopy with talc poudrage, long-term indwelling catheter, and pleuroperitoneal shunt 4, 5, 6

The British Thoracic Society recommends immediate chest tube drainage if frankly purulent or turbid fluid 7
The British Thoracic Society suggests prompt chest tube drainage if organisms on Gram stain or culture 7
The American Thoracic Society recommends chest tube drainage if pleural fluid pH <7.2 7

The European Respiratory Society recommends first-line aggressive medical management or adjustment of renal replacement therapy 2
The European Respiratory Society suggests serial thoracentesis preferred over IPCs as initial pleural intervention 2

The European Respiratory Society recommends optimizing medical therapies (diuretics, salt/fluid restriction) 2
The European Respiratory Society suggests serial thoracentesis if medical management fails 2
The European Respiratory Society recommends considering IPC if ≥3 therapeutic thoracenteses required 2

The American College of Chest Physicians recommends not performing pleurodesis without confirming complete lung expansion, and checking for endobronchial obstruction or trapped lung first 6
The British Thoracic Society suggests avoiding removing >1.5L in a single thoracentesis, due to risk of re-expansion pulmonary edema 4, 5
