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.

Talc is an effective and widely used agent for chemical pleurodesis. However, limited availability and high cost hamper the routine use of talc in resource poor countries. In this study, we compared the efficacy and safety of iodopovidone with that of cosmetic talc, for chemical pleurodesis.. Patients with recurrent pleural effusions and/or spontaneous pneumothorax were prospectively randomized to undergo pleurodesis with cosmetic talc (5g) or iodopovidone (20mL of a 10% solution) by tube thoracostomy. The cosmetic talc was pretested for impurities (asbestos-free) and particle size (20-60µm), using energy dispersive analysis by X-ray and scanning electron microscopy. The success rate (complete or partial), time to pleurodesis and safety of these two agents was compared.. Pleurodesis was performed in 73 patients (39 with iodopovidone, 34 with cosmetic talc; 56 men, 17 women; mean age 51.7 years; 38 pleural effusions, 35 pneumothoraces). A complete response was obtained in all patients with pneumothorax in both the iodopovidone and talc groups. Among patients with pleural effusions, a complete response was observed in 16/19 and 15/19 patients in the iodopovidone and talc groups, respectively. A partial response was observed in two additional patients from each group. The time to pleurodesis was similar in the two groups. Minor side-effects (fever, chest pain) were observed with similar frequencies in the two groups. None of the patients experienced hypotension or ARDS.. Iodopovidone and cosmetic talc are equally efficacious and safe agents for chemical pleurodesis.
