Aims: The aim of this study was to compare different radiation protection drapes in terms of radiation dose absorbed by operators during right or left transradial procedures. Methods and results: Patients who underwent transradial coronary procedures were randomised initially into four groups: Group 1 (no drapes), Group 2 (drape on patient's arm), Group 3 (pelvic drape), Group 4 (combined arm and pelvic drapes). Subsequently, each group was further randomised to right or left radial access. The primary endpoint was the operator radiation dose at the thorax. A total of 452 procedures were included. The use of drapes was associated with a lower radiation dose compared to no drapes (8.6 μSv [4.1-17.9] Group 1, 5.8 μSv [3.4-13] Group 2, 3.6 μSv [2.1-6.9] Group 3, 3.7 μSv [1.9-10.3] Group 4, p<0.001). Among radiation protection drapes groups the radiation dose was significantly lower in Groups 3 and 4 compared to Group 2 (p<0.008). Compared to Group 1, the dose in Group 2 was significantly lower only in right radial procedures (p<0.008) whereas in Groups 3 and 4 the dose was significantly lower in both radial accesses (p<0.008). Conclusions: The use of radiation protection drapes during transradial coronary procedures is associated with a significantly lower radiation dose to operators, with the pelvic drape more effective than the use of a single arm drape.

Abstract

Aims: The aim of this study was to compare different radiation protection drapes in terms of radiation dose absorbed by operators during right or left transradial procedures. Methods and results: Patients who underwent transradial coronary procedures were randomised initially into four groups: Group 1 (no drapes), Group 2 (drape on patient's arm), Group 3 (pelvic drape), Group 4 (combined arm and pelvic drapes). Subsequently, each group was further randomised to right or left radial access. The primary endpoint was the operator radiation dose at the thorax. A total of 452 procedures were included. The use of drapes was associated with a lower radiation dose compared to no drapes (8.6 μSv [4.1-17.9] Group 1, 5.8 μSv [3.4-13] Group 2, 3.6 μSv [2.1-6.9] Group 3, 3.7 μSv [1.9-10.3] Group 4, p<0.001). Among radiation protection drapes groups the radiation dose was significantly lower in Groups 3 and 4 compared to Group 2 (p<0.008). Compared to Group 1, the dose in Group 2 was significantly lower only in right radial procedures (p<0.008) whereas in Groups 3 and 4 the dose was significantly lower in both radial accesses (p<0.008). Conclusions: The use of radiation protection drapes during transradial coronary procedures is associated with a significantly lower radiation dose to operators, with the pelvic drape more effective than the use of a single arm drape.
