Hands are the most important way of transmitting infection. So, disinfecting hands with an appropriate substance is the most important prevention method. Therefore, the present study aimed to compare the effect of thyme spray and that of Decosept on the microbial load of nurses’ hands. 70 nurses working in different wards of Valiasr Hospital in the city of Arak, Iran, were selected according to inclusion criteria to participate in this clinical trial. After acquiring written consents, an initial culture was obtained from each participant on Blood Agar media. The participants were assigned to two groups. The first group disinfected their hands with thyme spray at 10% concentration and the second group disinfected their hands with Decosept. After drying the hands, a second culture sample was taken from each participant. Then, differential culture technique was performed and the results were analyzed by SPSS 16 and through t-test, Mann–Whitney, Fisher and Chi-squared tests. The results showed that both substances used in the intervention caused a reduction in microbial load of the participants’ hands (p=0.0001), but this reduction was significantly higher after using Decosept compared to thymus (p= 0.0000). The results of this study showed that the antimicrobial effect of Decosept is higher than that of thymus. However, due to increasing attempts to use plant-based antibacterial agents, considering the findings of this study to this aim is recommended.

Hand washing is an essential measure in controlling the infection in the operating room, the correct implementation of which requires time. Therefore, the use of fast-acting and safe disinfectant is of great importance in this regard. Regarding this, the present study aimed to compare the antiseptic effects of Betadine and Sterillium on the microbial load of the surgical hands.
This quasi-experimental study was conducted on 93 operating room staff working at teaching hospitals of Yazd, Iran, in 2013, using random sampling method. Hand washing was first performed uniformly using 5 ml of non-antibacterial soap for 1 min. Subsequently, the hand washing was performed on two separate occasions with an interval of one week with 12 ml of Betadine and Sterillum for 3 min following the instructions of each solution. The sampling was carried out immediately after hand washing. In order to evaluate the lasting effects of the disinfectants, another sampling was also performed after the surgery. The data were analysed using Chi-square tests, independent t-test, and repeated measures ANOVA through the SPSS version 17.
At post-intervention stage, the mean difference of microbial load of the hands washed with Betadine was 15.97±3.08 CFU/ml which decreased to -0.64±0.28 CFU/ml (P=0.012). Regarding the Sterillum, the mean microbial loads of the hands were 16.73±3.0 and -0.032±0.64 CFU/ml at the pre- and post-intervention stages, respectively (P=0.037). This difference between the two solutions was significant (P=0.04).
The findings of the present study revealed that the Sterillum was more fast-acting, than the Betadine. However, Betadine showed more lasting effect as compared to the Sterillum. Therefore, it is suggested to choose the disinfectant with regard to the onset and duration of the surgery.

To reduce surgical site infections and its complications، hand antiseptic is performed on the basis of product type either by rubbing or washing method. Silver Nanocolloid is a wide range disinfectant entered in world and also Iran markets as a surgical hand antiseptic، but any study about this subject hasn’t yet conducted. The aim of this study is comparing of Betadine، Sterillium and Silver Nanocolloid immediate effect on surgical hand antiseptic. This study design was randomized cross-over trial. Betadine، Sterillium، and Silver Nanocolloid with specific volume، duration (according to manufacturers’ instructions)، and intervals (at least 24 hours) is conducted on 30 volunteer''s hands. They occupy in operating room of hospital. Immediately after hands antisepsis، the samples were taken from the subject’s hands، transported to the blood agar plate، and plates were taken to the laboratory. In laboratory was incubated in 36 ± 1 degrees centigrade for 24 hours. For any growth medium، positive or negative of colony forming is surveyed and statistical analyses were conducted by SPSS software. There’s not a statistically significant difference between negative cultures of Betadine and Sterillium، but negative culture of Betadine 20 (66. 7%) and Sterillium 18 (60%)، each of them separately، is significantly greater than Silver Nanocolloid 30 (10%) (P < 0. 0001). 1 and 4 subjects experience much allergic reaction on their hands، respectively by using Sterillium and Silver Nanocolloid. The immediate antiseptic effects of Betadine and Sterillium are the same that conform to other studies and more than Silver Nanocolloid.
