Summary
Intraoperative fluoroscopy significantly increases surgeon radiation exposure, particularly to the hands. Implementing protective measures like shielding and reducing exposure time can mitigate these risks.
Area of Science:
- Medical Physics
- Surgical Safety
- Radiation Oncology
Background:
- Intraoperative fluoroscopy use is increasing, leading to significant surgeon radiation exposure.
- Public and patient radiation doses from diagnostic imaging are well-documented, but surgeon exposure requires specific attention.
- Surgeons face risks from primary beams and scatter radiation, especially to the hands.
Purpose of the Study:
- To highlight the substantial radiation exposure risks to surgeons during intraoperative fluoroscopy.
- To compare occupational radiation doses with established safety limits.
- To outline strategies for minimizing surgeon radiation exposure.
Main Methods:
- Review of radiation exposure data from intraoperative fluoroscopy (C-arm and mini C-arm).
- Comparison of estimated surgeon exposure to recommended yearly radiation limits for torso and hands.
- Identification and compilation of methods to reduce radiation exposure.
Main Results:
- C-arm devices deliver high radiation doses (1,200–4,000 mrem/min) to patients.
- Surgeon hand exposure can exceed previously estimated levels, even with mini C-arms.
- Estimated surgeon exposure can approach or exceed recommended yearly limits if not managed.
Conclusions:
- Surgeons are at significant risk of radiation exposure during procedures using intraoperative fluoroscopy.
- Effective radiation protection strategies are crucial for surgeon safety.
- Implementing measures such as increased distance, shielding, and optimized C-arm use can reduce exposure.
