Interventional cardiologists are exposed to radiation-induced diseases, partly due to patient's scatter radiation.
We sought to compare the radiation exposure (RE) of the cardiac catheterization room staff using SEPARPROCATH®, a novel radio-protective drape versus standard shielding equipment.
This was a two-step prospective, randomized pilot trial: first, in experimental conditions using a phantom model, and second, during cardiac catheterization. Primary end-point was operator RE corresponding to the ratio between operator cumulative dose (CD) and dose area product (DAP). Secondary end-points were nurse RE, operator and nurse CD, DAP, and fluoroscopy time.
A total of 51 patients were included. SEPARPROCATH® was associated with a lower operator RE (0.07 [0-0.19] vs. 0.37 [0.23-0.81] μSv/Gy.cm without SEPARPROCATH®, p value <0.0001) and lower nurse RE (0 [0-0.05] vs. 0.13 [0.03-0.28] μSv/Gy.cm , p value <0.0001) corresponding to an RE relative risk reduction of 81% and 99%, respectively. Similar reductions were observed for operator and nurse CDs. No difference was found in DAP (19 [11-29] vs. 14 [10-32] Gy.cm without SEPARPROCATH®, p value 0.81).
SEPARPROCATH® offers significant additional radioprotection to the operator and nurse during cardiac catheterization without affecting patient safety.
介入心脏病学家面临辐射诱导疾病的风险，部分原因是患者散射辐射。
我们旨在比较使用新型防辐射隔离服 SEPARPROCATH®与标准屏蔽设备时，心内科导管室工作人员的辐射暴露（RE）。
这是一项两步前瞻性随机试验：首先，在使用模型的实验条件下，其次，在心脏导管插入术期间。主要终点是操作员的 RE，对应于操作员累积剂量（CD）与剂量面积乘积（DAP）的比值。次要终点为护士 RE、操作员和护士 CD、DAP 和透视时间。
共纳入 51 例患者。SEPARPROCATH®与较低的操作员 RE（0.07 [0-0.19]与无 SEPARPROCATH®时的 0.37 [0.23-0.81] μSv/Gy.cm，p 值 <0.0001）和较低的护士 RE（0 [0-0.05]与无 SEPARPROCATH®时的 0.13 [0.03-0.28] μSv/Gy.cm，p 值 <0.0001）相关，RE 的相对风险降低分别为 81%和 99%。操作员和护士 CD 也观察到类似的降低。DAP 无差异（19 [11-29]与无 SEPARPROCATH®时的 14 [10-32] Gy.cm，p 值 0.81）。
SEPARPROCATH®在心脏导管插入术期间为操作员和护士提供了显著的额外辐射防护，而不影响患者安全。
