Measuring scatter radiation exposure during coronary procedures

Quantification and Determinants of Occupational Xray Scatter Radiation Exposure of Operators and Assistants During Coronary Procedures - The Occupational SCAtter Radiation Registry

Observational Paracelsus Medical University · NCT04945538

This study looks at how much scatter radiation doctors and assistants get during heart procedures to see if new protective devices can help reduce their exposure.

What this trial studies

This observational registry collects data on scatter radiation exposure experienced by operators and sterile assistants during diagnostic and interventional coronary procedures. Using digital live dosimeters, the study records radiation exposure at specific anatomical locations and correlates this data with detailed X-ray exposure metrics and technical aspects of the procedures. The aim is to establish reference values for scatter radiation, identify factors that contribute to high exposure, and evaluate the effectiveness of advanced radiation protection devices in clinical settings.

Who should consider this trial

Good fit: Ideal candidates include patients scheduled for coronary angiography or percutaneous coronary interventions, both elective and acute.

Not a fit: Patients who are not undergoing coronary procedures or those who do not meet the inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance radiation safety protocols, ultimately reducing exposure for healthcare workers during coronary procedures.

How similar studies have performed: While there have been studies on radiation exposure in medical settings, this specific approach to systematically collect and analyze scatter radiation data is relatively novel.
