[Comparison of antibacterial effects of different antiseptics after hand washing].
The aim of this study was to compare 4% chlorhexidine gluconate, 7.5% povidone iodine and liquid soap, which are used as hand washing solutions for the immediate, cumulative and residual effects in bacterial growth. For this purpose, 18 volunteers washed their hands with 7.5% povidone iodine, 4% chlorhexidine gluconate and liquid soap by applying standard hygienic hand washing technique. In order to find out the bacterial amount in the hands of study group, glove liquid test was used. For the evaluation of immediate effects, samples were collected just after the washing procedure, for the residual effects samples were collected from gloved hands after 3 hours, and for the cumulative effects, samples were collected after 5 days with daily hand washings. It is found that the immediate effects of 4% chlorhexidine gluconate was superior than others, and 7.5% povidone iodine was superior to liquid soap. There was no difference between 4% chlorhexidine gluconate and 7.5% povidone iodine for residual effects. The cumulative effects were observed for 4% chlorhexidine gluconate and 7.5% povidone iodine, while there was no cumulative effect for liquid soap. According to these results, it can be suggested that 4% chlorhexidine gluconate can be used as a reliable antiseptic agent in the hospitals, especially for laboratories, intensive care units and operating rooms, owing to its favourable immediate, residual and cumulative effects.
