국내 의과대학 학생의 확장한 외상환자 선별 초음파 검사(eFAST)의 수행 능력에 대한 평가와 고찰

Abstract

Purpose: Emergency physicians usually perform ultrasoundexams for patients with multiple injuries. Extended focusedassessment with sonography for trauma (eFAST) can revealinjuries from chest to the abdomen immediately. However, inKorea, the curriculums of medical schools do not currentlyinclude eFAST. We have devised a study to assess the feasibilityof the eFAST exam in medical school students. Methods: This study was conducted in students in their fifthyear out of six years of medical school, over 11 weeks. Four Emergency Medicine specialists trained the studentsover 4 hours, tested the students, and conducted a questionnaire. Results: Average age of students was 25.9±2.6 years,and 24 were male and 20 were female. Mean success rateof 17 components on the eFAST exam was 95.9% (94.6%-97.4%). The success rate of transverse view of aorta, transverseview of bladder, lung sliding sign, and sea-shore signof both anterior chest walls was 100%, scanning the spleenand attaching the probe to a body surface were 75%,86.3%. Total time consumption was 449.0±22.2 seconds. The questionnaires showed that the eFAST exam for thesplenorenal recess, spleen, and left upper quadrant lungwas difficult. Conclusion: We found that medical students in Korea couldperform the eFAST exam by themselves after 4 hours education. In the future, these findings can be helpful in developmentof an eFAST education program for medical students.
