Abstract

Objective: Despite known occupational radiation risks, data on exposure during digital radiography (DR) or fluoroscopy-guided equine fracture repair are lacking. This study quantified radiation doses to a model surgeon's hand, lenses, thyroid, and gonads, and assessed protective effects of radiation-reducing surgical gloves and attenuating ointment.

Study design: Comparative, controlled, simulation-based study.

Animal/sample population: Anthropomorphic model.

Methods: Distal limb fracture fixation was simulated using a model with dosimeters at the region of the lenses, thyroid, gonads, drill-holding hand, and under a lead apron (fetal dose). Radiation was measured over 10 DR or 10 single-image fluoroscopy exposures, then repeated using radiation-reducing surgical gloves or ointment.

Results: All radiation doses were below occupational limits. Dosimeters placed at the level of the gonads (outside the gown) received the highest mean dose (DR: 6.87 ± 0.40 μSv; fluoroscopy: 0.98 ± 0.28 μSv), followed by thyroid (outside the gown) (DR: 2.60 ± 0.52 μSv; fluoroscopy: 0.48 ± 0.08 μSv), hand (DR: 2.02 ± 0.54 μSv; fluoroscopy: 0.32 ± 0.06 μSv) and lenses (DR: 1.25 ± 0.28 μSv; fluoroscopy: 0.23 ± 0.07 μSv). The lowest exposure was measured underneath the gown (fetal dose) (DR: 0.01 ± 0.01 μSv; fluoroscopy: 0.01 ± 0.01 μSv). DR exposure exceeded fluoroscopy at all sites (p < .001). Radiation-reducing surgical gloves significantly lowered hand dose (p < .001), whereas ointment had no effect (p = .54). Off-beam hand exposure from 10 images was approximately one-millionth of the annual dose limit.

Conclusion: Image-guided equine distal limb fracture fixation results in minimal hand radiation exposure, relative to other regions of the body, with DR producing higher doses than single-image fluoroscopy. Radiation-reducing surgical gloves significantly lower hand exposure during DR procedures.

Clinical significance: Radiation-reducing surgical gloves offer additional protection and are recommended during image-guided surgery. Whenever feasible, pulsed fluoroscopy should be preferred over DR.

马外科医生在模拟数字x线摄影和透视引导下远端肢体骨折固定期间的辐射暴露。

目的：尽管已知职业辐射风险，但在数字x线摄影（DR）或透视引导下的马骨折修复术中暴露的数据缺乏。本研究量化了模型外科医生手部、晶状体、甲状腺和性腺的辐射剂量，并评估了减辐射手术手套和减辐射药膏的保护作用。研究设计：比较、对照、模拟研究。动物/样本种群：拟人化模型。方法：采用在晶状体、甲状腺、性腺、握钻手和铅围裙下（胎儿剂量）设置剂量计的模型模拟远端肢体骨折固定。在10次DR或10次单图像透视照射下测量辐射，然后使用降低辐射的手术手套或药膏重复。结果：辐射剂量均低于职业限值。放置在生殖腺（衣外）水平的剂量计平均剂量最高（DR: 6.87±0.40 μSv，透视：0.98±0.28 μSv），其次是甲状腺（衣外）（DR: 2.60±0.52 μSv，透视：0.48±0.08 μSv）、手部（DR: 2.02±0.54 μSv，透视：0.32±0.06 μSv）和镜片（DR: 1.25±0.28 μSv，透视：0.23±0.07 μSv）。袍子下测最低暴露量（胎儿剂量）（DR: 0.01±0.01 μSv；透视：0.01±0.01 μSv）。结论：与身体其他部位相比，图像引导的马远端肢体骨折固定导致的手部辐射暴露最小，DR产生的剂量高于单图像透视。减少辐射的外科手套可显著降低DR过程中的手部暴露。临床意义：降低辐射的手术手套提供额外的保护，建议在图像引导的手术中使用。在可行的情况下，脉冲透视优于DR。

期刊介绍： Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
