Summary based on

the abstract

What it found

• After adjustment for body mass index, patient air kerma was lower with the mobile C-arm than with the fixed C-arm.

  Key figures: 124.1 ± 142 vs. 173.3 ± 248.7 mGy, P = 0.025

• Effective dose to senior surgeons and operating room nurses did not differ between mobile and fixed systems.

• The trainee resident and nurse anesthetists recorded a higher effective dose on the external dosimeter with the mobile C-arm.

• The authors conclude the type of imaging system does not appear to affect staff exposure overall.

Limits to keep in mind

Nonrandomized groups with unequal sizes and a small staff-dose series (24 vs 76 patients); abstract only, with no staff dose values or country reported.
