Shields and garb for decreasing radiation exposure in the cath lab

摘要

INTRODUCTION: Decreasing radiation exposure of the cardiac catheterization laboratory staff is critical for minimizing radiation-related adverse outcomes and can be accomplished by decreasing patient dose and by shielding. Areas covered: protection from ionizing radiation can be achieved with architectural, equipment-mounted, and disposable shields, as well as with personal protective equipment. Expert commentary: Radiation protective aprons are the most commonly used personal protective equipment and provide robust radiation protection but can cause musculoskeletal strain. Use of a thyroid collar is recommended, as is use of 'shin guards', lead glasses and radioprotective caps, although the efficacy of the latter is being debated. Alternatives to lead aprons include shielding suspended from the ceiling and robotic percutaneous coronary intervention. Radiation protective gloves and cream can be used to protect the hands, but the best protection is to not directly expose them to the radiation beam. Devices that provide real time operator radiation dose monitoring can enable real time adjustments in positioning and shield placement, reducing radiation dose. Shielding can be achieved with architectural, equipment-mounted, and disposable shields. Equipment-mounted shielding includes ceiling-suspended shields, table-suspended drapes, and radioabsorbent drapes. Personal protective equipment and shielding should be consistently and judiciously utilized by all catheterization laboratory personnel.
