The search for an 'ideal' agent for pleurodesis continues. Iodopovidone is a topical antiseptic and has been shown to be safe and effective in many studies. The aim of this study was to evaluate the efficacy and safety of iodopovidone as an agent for chemical pleurodesis. We performed a systematic review of all the observational trials which have used iodopovidone for chemical pleurodesis. Six studies including 265 patients who had undergone chemical pleurodesis with iodopovidone were included for this analysis. Iodopovidone was used for variety of indications, which included pleural effusion (157 patients), and pneumothorax (108 patients). Pleurodesis was performed through tube thoracostomy in 144 patients and through thoracoscopy in 121 patients. The success rate of pleurodesis varied from 64.2% to 100%, and summary success rate of all the studies was 90.6% (95% confidence intervals [CI], 86.4-93.8). The success rate was independent for the procedure (tube thoracostomy [126/144; 87.5%, 95% CI 80.9-92.4] or thoracoscopy [114/121; 94.2%, 95% CI 88.4-97.6]) used for performing pleurodesis or for the indication (pleural effusion [139/157; 88.5%, 95% CI 82.5-93.1] or pneumothorax [101/108; 93.5%, 95% CI 87.1-97.4]). The only significant complication reported was chest pain of varying degree. Systemic hypotension was reported in three patients in only one study. There were no deaths related to chemical pleurodesis with iodopovidone. Overall, this review supports the safety and efficacy of iodopovidone as an agent for chemical pleurodesis in cases of recurrent pleural effusions and pneumothoraces regardless of their etiology.
