Abstract

Purpose: The present study purposed to compare the hand washing effect of 7.5% povidone-iodine, which is used in the operation room of C university hospital in Seoul, with that of Ethyl alcohol-CHG mixture recommended by the US Association of Operating Room Nurses (2002) and to adopt a more effective hand disinfectant.
Method: In a quasiexperimental design, 48 medical staff who participated in operations during the period from November 2004 to February 2005 had hand washing using the two kinds of hand disinfectants: 7.5% povidone-iodine and the ethyl alcohol-CHG mixture. Their palms were swabbed and cultured just after hand washing and again after taking off sterile gloves after the operation. The number of colonies from the two occasions were counted and compared.
Result: The number of general bacillus increased significantly in the group using 7.5% povidone-iodine compared to that in the group using the ethyl alcohol-CHG mixture. The number of general bacillus increased significantly in doctors compared to that in nurses. The factors affecting the increase of the number of general bacillus were disinfectants and medical personnel. The number of general bacillus was expected to increase 9.41 times with 7.5% povidone-iodine than with the ethyl alcohol-CHG mixture and 14.87 times in doctors than in nurses.
Conclusion: This study shows that the ethyl alcohol-CHG mixture has a stronger hand disinfection effect than 7.5% povidone iodine. Thus we need to change the hand disinfectant used in operating rooms as soon as possible in order to minimize the infection of wounds resulting from operations.
