초록

뇌파검사는 뇌전증의 진단과 뇌 기능을 검사하는 것으로 이용된다. 임상병리사는 뇌파검뇌파 시행할 때 International 10~20 electrode system에 따라 정확하게 전극을 부착하고 인공산물 없이 의사들이 정확한 판독을 할 수 있게 뇌파를 기록하는 업무를 담당한다. 이러한 뇌파검사를 시행하는 임상병리사를 양성하기 위해 대학의 교육과정에서 실습시간을 통해 실무능력을 배양하게 되는데, 뇌파검사의 경우 정확한 전극 부착위치를 찾는 것이 학생들의 애로사항이었다. 본 연구에서는 전극부착위치를 쉽고 신속하게 찾아 학생들의 애로사항을 해결하기 위해 위치밴드를 제작하여 교과서에 기재된 줄자법과 전극 부착위치 찾는 방법을 비교하였다. 그 결과 피검자의 자세(앉은 자세 vs 누운 자세)에 따라 밴드법은 (196.7±61.8초 vs 200.2±49.3초), 줄자법은 (1281.0±457.4초 vs 1417.9±482.3초)로 앉은 자세일 때는 1084.3초(18.1분), 누운 자세일때는 1217.7초(20.3분)의 차이를 보여 줄자법보다 밴드법의 사용이 신속하다는 것을 확인하였다. 또한 전극 부착위치를 찾는데 영향을 줄 수 있는 교육과정 내의 뇌파 검사실습의 경험 유무와 피검자의 성별에 따른 차이에서도 밴드법은 줄자법보다 시간적인 차이가 적다는 것을 확인하였다. 본 연구에서 개발한 위치밴드를 사용한 줄자법을 사용하게 되면 대학의 교육과정에서 뇌파검사 실습시 애로사항이었던 전극 부착위치 찾는법을 신속하고 효율적으로 해결할 수 있다는 것을 확인하였고, 임상에서 신규 임상병리사들에게 교육하는데 적용도가 높을 것으로 사료된다. 다만 International 10~20 electrode system의 줄자법과 마찬가지로 전극 부착위치에 대한 정확성을 판정하는 기준에 대해서는 좀 더 연구가 필요할 것이다.

Electroencephalography (EEG) is used for the diagnosis of epilepsy and testing the brain function. Clinical technologists are responsible for recording EEG without artifacts in accordance with the international 10~20 electrode system. Training on these techniques requires practical education. In the case of EEG, however, it is difficult for trainees to find the correct location of the electrode. Therefore, this study compared the time spent to locate the electrode attachment between traditional tape and the newly developed band. The time spent for sitting position patients using the band (196.7±61.8s) was 1084.3 s faster than the tape (1,281.0±457.4s) (P<0.001). Furthermore, the spend time spent for lying position patients using the band (200.2±49.3s) was 1217.7s faster than the tape (1417.9±482.3s) (P<0.001). Measurements using the band showed fewer differences due to various factors, such as position, practical experience, and gender. The newly developed band can locate the correct electrode attachment position quickly and efficiently, which has been a difficult problem in EEG practical education. In addition, this band is expected to be applied widely by new clinical technologists in the clinical field. Nevertheless, more study will be required to verify the accuracy of the location of the attaching electrode.
