Effect of new radioprotective equipment on decreasing radiation of participants in percutaneous coronary interventional procedure

Background: The hazard of ionizing radiation to medical staff in Percutaneous Coronary Interventional procedure (PCI) is the largest among all interventional procedures and increasing, this phenomenon has received the attention of researchers in various countries. Radiation protective shielding equipment is an accepted effective measure, but protective performance is associated with poor applicability for diverse interventional procedures. The aim of this study attempted to develop new radioprotective shielding equipment for PCI and measure its effectiveness and applicability. Methods: This study established a radioprotective cabin for PCI and used fluoroscopy and cine modes of DSA machine to compare the effectiveness between the experimental group (radioprotective cabin) and control group (current normal radioprotection). A 231 radiation intensity data collected, dots were set around the standardized patient, 210 points were distributed on the vertical plane around the therapy bed, and 21 points were evenly distributed in the patient's thyroid, head, and gonadal area. Results: Based on cine modes, there were statistically significant differences between the 2 groups of the radiation intensities in the left plane, right plane, foot plane, head and face area, and the gonads area (Z=-6.645, -5.615, -6.204, -2.647, -2.882, P<0.05). Based on fluoroscopy modes, there were statistically significant differences between 2 groups of the radiation intensities in the left plane, right plane, foot plane, and gonads area (Z=-6.060, -5.083, -5.203, -2.887, P<0.05) Conclusion: The radioprotective cabin can effectively reduce the radiation intensity in the routine standing area and radiation-sensitive areas of the patient without affecting the operation, which can be strongly promoted in PCI procedure.
