OBJECTIVES Concerns about radiation exposure for health care workers have increased in the last decade, along with the increased use of fluoroscopic imaging for surgical procedures. Recent literature suggests that surgeons with the least experience have higher exposure during surgery, and their perception of exposure may be lower. The purpose of this study was to examine the accuracy of orthopedic resident trainees' estimates of their exposure during fluoroscopy cases. MATERIALS AND METHODS Orthopedic resident trainees were surveyed after participation in various fluoroscopic orthopedic surgeries and asked to estimate the number of fluoroscopy exposures used. Their answers were compared against the actual number of exposures retrieved from the fluoroscopy machine. The perceived number of exposures was then compared to the actual number taken for junior residents in training year 1, 2, or 3 versus senior residents in training year 4 or 5. RESULTS Nineteen residents were surveyed, 13 of which were junior residents and six of which were senior residents. Of the 13 junior-level residents, total estimation was 441 exposures, versus 1411 actual exposures, an underestimation of over 69%. The six senior residents totaled 457 estimated exposures, compared to 645 actual exposures, for an underestimation of just under 30%. CONCLUSIONS In this survey study at a single institution, junior-level residents greatly underestimated radiation exposure compared to senior-level residents. Trainees should be aware that they grossly underestimate their exposure levels during procedures, and residency programs should emphasize fluoroscopic training early.

低估了骨科居民的透视透视。

目的在过去的十年中，随着越来越多的荧光镜成像用于外科手术，人们越来越担心医护人员的放射线。最近的文献表明，经验最少的外科医生在手术过程中的暴露程度较高，并且他们对暴露的感觉可能较低。这项研究的目的是检查骨科住院医师在透视检查过程中其暴露估计的准确性。材料与方法参加各种透视手术的骨科住院医师接受了调查，并要求他们估计所使用的透视检查的次数。将他们的答案与从荧光检查仪上获得的实际曝光次数进行比较。然后，将感知到的接触次数与培训第一，第二或第三年的初级居民与培训第四或第五年的老年居民的实际人数进行比较。结果调查了19位居民，其中13位为初级居民，六位为第二位。是老年人 在13位低级居民中，总估计人数为441人，而实际人数为1411人，低估了69％以上。六名高级居民的估计暴露总数为457，而实际暴露为645，低估了近30％。结论在单机构的这项调查研究中，与高级别居民相比，低级别居民大大低估了辐射暴露。学员应注意，他们在程序中严重低估了他们的暴露水平，
