the radiation dose of the first operator and second operator standing areas. Thus, solving the problem of high radiation dose to the second operator pointed out in this study, and at the same time, the cabin also reduced the radiation dose in the area at the end of the operating table. Combined with the fact that the area at the end of the operating table is the area with the lowest radiation dose as pointed out in this study( Liu et al., 2023). The effect of the cabin in reducing the radiation dose during cardiac catheterization interventions can be comprehensively explored in a follow-up study.
The results of the radiation dose analysis in this study provide radiation protection suggestions to operators and nurses, but more importantly, any radiation protection suggestions must be accepted and cooperated with by operators and nurses in order to achieve the best radiation protection effect, and this accepted and cooperation is related to the hospital’ s training and system, but due to the rapid updating of radiation protection measures in cardiac catheterization interventions, the training progress and system of most hospitals are relatively backward. resulting in less-thanoptimal radiation protection measures for operators and nurses( Bertho and Geryes, 2023). In the researcher’ s follow-up study, research on attitudes toward radiation protection in cardiac catheterization interventions will be prioritized.
5 Conclusion
In this study, the researchers investigated the radiation dose levels in various areas of the cardiac catheterization room during cardiac catheterization interventions. Our results showed that nurses should choose the area at the end of the operating table to stand during the intervention, as well as the equipment and supplies in the cardiac catheterization room should also be placed in this area to avoid higher radiation exposure for nurses. The radiation doses of the first and second operators remind us to pay more attention to the radiation exposure of the second operator, and to improve the radiation protection measures of the DSA machine in a timely manner, also in the cephalic( CRA 30 °) and left anterior oblique( LAO 45 °) positions, the operator needs to take additional measures to minimize the increase in radiation dose.
5.1 Limitation
The cardiac catheterization room in which this study was conducted is not generalized, and the different layouts of facilities in different cardiac catheterization room lead to possible differences in radiation dose from this study. In subsequent studies, the distribution of radiation dose in cardiac catheterization rooms with different layouts will be analyzed, and simulations will be used to explore the patterns, so that standards for the placement of cardiac catheterization room equipment supplies and standing areas for operators and nurses can be developed, and the probability of radiation-related occupational illnesses occurring in operators and nurses can be reduced.
