Zero-cost Radiation Protection Method to Reduce Radiation Exposure of Interventional Cardiologists During Transradial Percutaneous Coronary Procedures (FREEPADRAD Trial)
Sponsor: National and Kapodistrian University of Athens
Summary
Ionising radiation is a recognised occupational hazard in interventional cardiology. This prospective, randomised trial aims to evaluate the effectiveness of additional radiation protection by existing devices but with a different use, specifically the use of medical lead aprons (designed and used to be worn by the medical and nursing staff for radiation protection) covering the patient's lower abdominal and pelvic area during transradial coronary angiography and angioplasty. The intervention's efficacy will be assessed by measuring the reduction in operator radiation exposure and determining the impact of various clinical and procedural factors.

Interventions
Patient-Applied Pelvic Lead Shielding
The intervention involves the application of a triple-layer lead apron to the patient's lower abdominal and pelvic region during transradial coronary procedures. The apron measures 75 cm × 45 cm and is composed of three layers of 0.25 mm Pb-equivalent material. This protective shield is placed on the patient in addition to standard operator radiation protection measures. The primary goal of this intervention is to reduce scatter radiation exposure to the operator, thereby improving occupational safety in the catheterization laboratory. This approach leverages existing radiation protection materials in a novel configuration.
