Pleurodesis is performed to prevent recurrence of pneumothorax or recurrent pleural effusion. It can be done chemically or surgically. It is generally avoided in patients with cystic fibrosis, if possible, because lung transplantation becomes more difficult following this procedure.
Chemicals such as bleomycin, tetracycline e.g. minocycline, povidone iodine, or a slurry of talc can be introduced into the pleural space through a chest drain. The instilled chemicals cause irritation between the parietal and the visceral layers of the pleura which closes off the space between them and prevents further fluid from accumulating.
Povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.
Chemical pleurodesis is a painful procedure, and so patients are often premedicated with a sedative and analgesics. A local anesthetic may be instilled into the pleural space, or an epidural catheter may be placed for anesthesia.
Surgical pleurodesis may be performed via thoracotomy or thoracoscopy. This involves mechanically irritating the parietal pleura, often with a rough pad. Moreover, surgical removal of parietal pleura is an effective way of achieving stable pleurodesis.
Alternatively, tunneled pleural catheters (TPCs) may be placed in an outpatient setting and often result in auto-pleurodesis, whereby portable vacuum bottles are used to evacuate the pleural fluid. Routine evacuation keeps the pleura together, resulting in physical agitation by the catheter, which slowly causes the pleura to scar together. This method, though the minimally invasive and minimal cost solution, takes an average of about 30 days to achieve pleurodesis and is therefore the slowest means of achieving pleurodesis among other modalities.
