Mini C-Arm: Are the risks truly 'mini' to theatre practitioners?

Area of Science:

• Medical Imaging
• Radiation Safety
• Orthopaedic Surgery

Background:

• Mini C-Arm devices are increasingly used in orthopaedic and extremity surgeries.
• They are understood to minimize radiation exposure and scatter compared to conventional C-Arms.
• Concerns persist regarding occupational radiation exposure for staff routinely using these devices.

Purpose of the Study:

• To review current literature on cumulative radiation exposures associated with Mini C-Arm use.
• To evaluate risks for anaesthesia providers and other operating room personnel.
• To emphasize the importance of safety protocols despite potential radiation reduction.

Main Methods:

• Systematic literature review.
• Synthesis of existing studies on Mini C-Arm radiation exposure.
• Focus on occupational cumulative doses for surgical staff.

Main Results:

• While Mini C-Arms may reduce direct radiation and scatter, they do not eliminate risk.
• Anaesthesia providers, surgeons, and scrub practitioners face potential repetitive radiation doses.
• Staff remaining near the patient are particularly susceptible to scatter radiation.

Conclusions:

• Mini C-Arm use in surgery is not without occupational radiation risk.
• Appropriate shielding, safety protocols, education, and proper use are essential.
• Protecting healthcare workers from radiation hazards requires diligent adherence to safety measures.
