Abstract

Background and Aim: Surgical site infection (SSI) is one of the most common health-care associated infections. Using proper antiseptic solutions for preoperative surgical site skin preparation (skin prep) is one of the methods to reduce SSIs. The purpose of this study was to compare the effect of preoperative surgical site skin preparation with povidone-iodine and chlorhexidine-gluconate on the rate of SSI in laparotomy patients.
Materials and Methods: A total of 70 Laparotomy surgery patients who referred to Firoozgar hospital in Tehran from May to September of 2021 were included in this clinical trial. Patients were randomly allocated into two groups which were treated with povidone-iodine(PVI) or chlorhexidine-gluconate (CHG) for surgical site skin prep. Skin prep was done with standard rotational method in two steps by the researcher for each group by using of PVI and CHG. SSI incidence was assessed by a researcher-made check list and also over post-surgical follow up visits by the surgeon. We used Fischer’s exact test, t-test, Chi-square and Cochrane’s Q-test to analyze the collected data.
Results: SSI was seen in five patients (14.29%) of PVI group and one patient (2.86%) of CHG group. Although the SSI incidence in PVI group was 5.54 times more than CHG group, still the difference wasn’t statistically significant (P=0.198). Comparing the incidence of SSI’s in 24 hours after surgery (0%) and 30 days after surgery (8.57%) in both groups revealed that using these antiseptics for skin prep was effective in preventing SSI (P<0.001). SSI incidence was also associated with two days of patient’s hospital admission time (P=0.001).
Conclusion: The result of this study revealed that the occurrence of SSI in PVI group was 5.54 times more than CHG group. However, the difference was not statistically significant. So both of these antiseptics can be used for surgical site skin prep.

Abstract

Background and Aim: Virtual networks have become one of the most influential tools in people’s lives, affecting various aspects of life. In medical sciences, with numerous advancements, the use of virtual networks is increasing. However, virtual networks can lead to wastage of students’ time and a reduction in study hours, which negatively impacts their knowledge and practical skills. Therefore, this study aimed to investigate the impact of using virtual networks on the knowledge and practical skills of surgical technologist students.
Materials and Methods: This descriptive-analytical study was conducted on 60 students in the 6th and 8th semester of operating room technology at Iran University of Medical Sciences in 2020-2021. At the end of the semester, the students underwent a comprehensive 40-question theoretical exam to assess their theoretical knowledge. To evaluate the level of virtual network usage, the students filled out a researcher-designed questionnaire. The practical skills of the students were measured based on their internship grades. Normality of the data was assessed using the Kolmogorov-Smirnov, and Pearson correlation coefficient test. Data analysis was performed using SPSS software.
Results: According to the findings of this study, there was a significant negative relationship between the level of virtual network usage and theoretical knowledge (P<0.05). This means that with an increase in virtual network usage, the level of students’ knowledge decreased. On the other hand, there was a significant positive relationship between theoretical knowledge and practical skills. This means that as the scores of the comprehensive exam increased, the scores of practical skills (internship) also increased. However, no significant relationship was found between the level of virtual network usage and students’ practical skills (P>0.21).
Conclusion: Based on the findings of this study, virtual networks lead to a weakening of students’ theoretical knowledge, as evidenced by the decrease in scores on the researcher-designed questionnaire (level of virtual network usage) and the comprehensive exam scores. Another result of the study was the significant positive relationship between theoretical knowledge and practical skills, indicating that as the comprehensive exam scores increased, the scores obtained in internships also increased.
