Background
Teaching adequate and standard hand movements of surgical hand rub technique is a priority of „Basic Surgical Techniques" course. To check and visualize the effectiveness of the process UV light was used after applying fluorescent antiseptic solution.
Material and Methods
The trial was conducted with 253 students in the 10th (Test-I) and 14th week (Test-II) of the educational program. The hand rub's last phase was done with fluorescent solution then the hands were placed under UV light. Photos were taken and analyzed with software. Based on the error numbers, localization and pixel numbers, the specified area and intensity were compared. Error
considered being an area, where the fluorescent solution didn't show completely or with significant intensity difference. The palmar(P) and dorsal(D) hand surfaces were divided into 4 regions (1: distal phalanx, 2: thumb and metacarpus I, 3: fingers II-V, 4: metacarpus II-V).
Result
At Test-I 123, while at Test-II only 65 students' technique were objectionable: 2.56+/-1.7(1-9) and 2.02+/-1.1(1-6) erroneous regions. On both hands the most frequent localization of errors were D/2 and P/4 in Test-I, while D/1 and P/4 in Test-II. During the second survey there was an improvement in the number of erroneous regions and their extension. The right-handed students made less errors on their non-dominant hand compared to the left-handed students (n=23).
Conclusion
The method was suitable to monitor the efficacy of hand rub technique and identify the critical territories.
