Riansuwan K Background: The decontamination for foot and ankle surgery should be considered as a special preparation due to higher rate of bacterial contamination. The footwear and humidity is also the issue of interest especially in tropical country. The contamination before surgery should be reduced to avoid the infection. The effectiveness of antiseptics and special condition for the foot and ankle surgery should be elucidated for better medical care.
Material and Method: The twenty volunteers were included in the present study. In group I, the foot was scrubbed with 7.5% Povidone-Iodine and painted with 10% Povidone-Iodine solution. In group II, the foot was scrubbed with Chlorhexidine gluconate scrub and painted with 2% Chlorhexidine gluconate in 70% alcohol. At the beginning and end of the preparation, specimens were taking from all toes, nail fold, interdigital web spaces. These samples were sent for aerobic bacterial cultures. The results were interpreted as positive or negative cultivation and the number of bacterial colonies.
Results: All of the samples from 40 feet were collected; In Group I, positive culture was 5 samples (25%). In Group II, positive culture was 2 samples (10%) (p = 0.2).
Conclusion: The Chlorhexidine gluconate and Povidone-Iodine are effective in reduction the number of bacterial colonization. The steps of preparation before surgery also play an important role in eliminating the pathogenic bacteria. Both antiseptics were found no significant different in efficacy of pathogenic bacteria reduction.
