Introduction The management of recurrent pleural effusion or pneumothorax has always been a cause for serious concern among chest physicians. Among the wide variety of agents that are available for pleurodesis, povidone iodine is now perhaps the most sought after agent as it is cheap, easily available, effective and safe. This study was conducted to establish the efficacy and safety of povidone iodine as an agent for pleurodesis in patients with recurrent pleural effusion and pneumothorax.
Methods A total of 38 consecutive patients with symptomatic malignant or recurrent pleural effusion and pneumothorax received povidone iodine for pleurodesis over a period of 18 months. The mean follow-up period was 10.2 months, with a standard deviation of 2.9 months.
Results Out of the 38 patients, 29 had malignant pleural effusion, eight had recurrent pneumothorax and one had tubercular pleural effusion which was nonresponsive to anti-tubercular therapy. A complete response with no recurrence during follow-up was obtained in 34 (89.5 percent) patients. All the cases of failure had malignant pleural effusion. Three (7.9 percent) patients experienced intense chest pains after the installation of sclerosing agent, but they recovered with immediate symptomatic management.
Conclusion Recurrent pleural effusion or pneumothorax due to any cause may be managed effectively and safely by chemical pleurodesis with povidone iodine. It may be considered as the agent of choice to achieve pleurodesis, especially in resource constrained countries like India, as it is inexpensive and easily available.
