Summary based on

the abstract

What it found

• Operator wrist dose was significantly higher with the right radial approach than the left radial approach.

  Key figures: 2.44±1.12 mSv vs 1±0.8 mSv, P=0.002

• No significant difference in monthly thorax dose between approaches.

  Key figures: 0.85±0.46 mSv right radial access (RRA) vs 1.12±0.78 mSv left radial access (LRA), P=0.33

• Thyroid and shoulder doses were similar between approaches.

  Key figures: thyroid 0.36±0.2 vs 0.34±0.3 mSv, P=0.87; shoulder 0.73±0.44 vs 0.94±0.42 mSv, P=0.27

• Thoracic dose under the lead apron was undetectable with both approaches.

• Fluoroscopy time did not differ between groups.

  Key figures: 369 s vs 362 s, P=0.58

Limits to keep in mind

Only three operators with monthly pooled dosimeter readings, limiting statistical power and generalisability; randomisation was of patients, not operators, and the country and centre are not stated in the abstract.
