Radiation exposure during trauma care has increased in recent years. Radiation risk to providers during the care of injured patients is not well defined. We aimed to gather environmental exposure data from dosimeters placed at fixed points in the trauma bay to act as surrogates for personnel radiation exposure during trauma team activations. Forty-four (44) radiation dosimeters were placed throughout a single trauma bay in a university level 1 trauma center. We analyzed shallow (SDE) and deep dose equivalents (DDE) over 6 months. We measured distance from the radiation source for each dosimeter. Four controls were included. We recorded patient injury and X-ray data for each patient. During the study period, 417 patients were evaluated in the trauma bay under study. Mean ISS was 14.3 (range 0-75). A total of 2,107 plain X-rays were taken, with a mean of 5.1 X-rays per patient (range 0-32). Extremity films were most often performed, followed by chest and shoulder films. No measurable dose was identified with the dosimeter controls. The majority (27, 68 %) of dosimeters registered the lowest doses (<1 mSv DDE). Five dosimeters revealed doses between 1 and 2 mSv DDE. Four dosimeters registered over 2 mSv DDE, with a mean DDE of 3 mSv. Distances of less than 5 ft from the radiation source had the highest DDE dose. Maximum annual occupational DDE dose is conventionally 50 mSv. None of the dosimeters registered DDE doses over 4.31 mSv during the study period, supporting low radiation risk to providers in the trauma bay.
近年来，创伤救治过程中的辐射暴露有所增加。在救治受伤患者过程中，医护人员面临的辐射风险尚未明确界定。我们旨在收集放置在创伤室固定点的剂量仪的环境暴露数据，以此作为创伤团队启动期间人员辐射暴露的替代指标。在一所大学一级创伤中心的单个创伤室中放置了44个辐射剂量仪。我们分析了6个月内的浅表剂量当量（SDE）和深部剂量当量（DDE）。我们测量了每个剂量仪与辐射源的距离。纳入了4个对照组。我们记录了每位患者的损伤情况和X线数据。在研究期间，在所研究的创伤室对417例患者进行了评估。平均损伤严重度评分（ISS）为14.3（范围0 - 75）。共进行了2107次普通X线检查，每位患者平均5.1次X线检查（范围0 - 32）。四肢X线片检查最为常见，其次是胸部和肩部X线片。剂量仪对照组未检测到可测量的剂量。大多数（27个，68%）剂量仪记录的剂量最低（DDE<1 mSv）。5个剂量仪显示的剂量在1至2 mSv DDE之间。4个剂量仪记录的DDE超过2 mSv，平均DDE为3 mSv。距离辐射源小于5英尺处的DDE剂量最高。传统上，职业年最大DDE剂量为50 mSv。在研究期间，没有剂量仪记录的DDE剂量超过4.31 mSv，这表明创伤室内医护人员面临的辐射风险较低。
