| Expected Outcome: The hypothesis of the study is that the surgeon's skin will present less redness, scaly and fissures performing the surgical preparation of the hands with alcoholic solution compared to the degermants. This evaluation was performed by application by WHO instrument assistants while surgeons prepared the hands with degermante solution and alcoholic solution. This instrument consists of the items redness, scaly, fissures and visual skin scale score. Each item has its score scale. Thus the observer assigned a score from 0 to 4 in the item “redness”, 0 for “not red”, 1 for “slightly reddish or mottled”, 2 for “moderate redness, evenly distributed”, 3 for “bright red, scattered ”and 4“ very bright red ”, from 0 to 3 in the items“ scaly ”, being 0 for“ no scaly ”, 1 for“ very little or occasional ”, 2 for“ moderate ”and 3 for“ very pronounced separation of edges of the skin scale ”from 0 to 3 also for“ cracks ”, 0 being“ no cracks ”, 1“ very thin ”, 2“ large single or multiple ”and 3“ extensive cracks with bleeding or secretion ”. In addition, the observer scored a “visual skin scale score” of 0 to 5, with 0 for “no observable scale or irritation of any kind”, 1 for “occasional scale not necessarily evenly distributed”, 2 for “dry and / or red skin”, 3 for “very dry whitish-looking, rough to the touch and / or reddish but not cracked” skin, 4 for “cracked skin but no bleeding / discharge” and 5 for "Extensive skin surface cracks with bleeding / discharge".;Outcome found: When comparing the use of alcoholic solution with PVP-I and CHG for the surgical preparation of the hands, there was no statistically significant difference in the items “redness”, “scaliness”, “cleft” and “point of view” in the hands of the surgeons who used it. PVP-I and alcohol solutions. However, when comparing CHG solution and alcohol solution, there was a difference in the “redness” item, ie, surgeons more often presented redness when using alcohol (57.1%) compared to the time when | — |

| Expected Outcome 2: The hypothesis of the study is that the surgeon's skin will have better acceptability of the alcoholic solution compared to the degermant. This evaluation was performed through the application of a WHO instrument while after the surgeons prepared the hands with the degermant products and the alcoholic solution. The professional scored on a Likert-type scale his own opinion about product tested in the items “color” and “odor” (1 = unpleasant to 7 = pleasant), “texture” (1 = very viscous to 7 = not at all viscous ), “Irritation” (1 = very annoying at 7 = not at all annoying), “dryness” (1 = with very dryness at 7 = no dryness effect), “ease of use” (1 = very difficult to 7 very easy), “drying speed” (1 too slow at 7 = very fast), “application” (1 = very unpleasant at 7 = very nice), and “overall rating” (1 = dissatisfied at 7 = very satisfied ).;Outcome found 2: In comparing the acceptability of the solutions used in surgical hand antisepsis, there was no difference in the evaluation of the items “color”, “odor”, “irritation”, “dryness”, “ease of use”, “application” and “general evaluation”. CHG versus alcohol solution, however, there was a difference regarding the evaluation of the item “texture”, with the surgeons considering the alcoholic solution with better texture in relation to the degenerating CHG (71.4%). When compared PVP-I with alcohol solution there was no difference of evaluation in the items “irritation” and “ease of use”, but there was difference in the evaluation of the items “color”, “odor”, “texture”, “dryness”, “ application ”and“ general evaluation ”, that is, the surgeons considered the alcoholic solution with the most pleasant color and odor (73.3% and 66.6%), of better texture (60%), with less drying effect on skin (60%), more pleasant application (66.6%) and greater satisfaction with the overall assessment (66.6%). For data analysis, the items of the instrument were dichotomized into an evaluation considered good (yes or | — |
