Pleurodesis may be indicated for pleural effusions (with careful patient evaluation) or recurrent pneumothoraces. It is contraindicated if tube thoracostomy fails to reexpand the lung and, possibly, if patients are candidates for lung transplantation or have congestive heart failure. We perform pleurodesis through an indwelling chest tube (alternative methods are thoracoscopy and thoracotomy). Common sclerosants include talc, doxycycline, minocycline, and bleomycin. Intrapleural administration of lidocaine may control pain, but injections of morphine or meperidine almost always are needed.
