| Abstract:: |
| Objective To discuss the influence of the change in ceiling-mounted shield positions on the radiation doses to the first and second operators during percutaneous coronary intervention.Methods In this study, the entrance surface dose (ESD) rates were measured for the first and second operators at 125 cm and 155 cm height on different ceiling-mounted shield positions separately through transradial approach. Measurements were repeated 20 times for each position and T test was used for statistical analysis of dose rate arithmetic mean values. Results For the first operator, the effective dose values were obtained only on left foot position. The ESD rate values at ceiling-mounted shield position close to patient were higher than that close to operators (t125=46.9, t155=4.1, P<0.05). For the second operator, the ESD rate values on his foot position, right foot position, left anterior oblique position and right anterior oblique position at ceiling-mounted shield position close to the operator, were higher than that close to the patient separately (t125=11.9, 24.4, 11.2, 2.7, t155=16.1, 2.8, 14.4, 28.8, P<0.05). The ESD rate values on head position, left foot position, left head position at ceiling-mounted shield position close to the operator, were lower than that close to the patient (t125=-4.3, -2.4, -80.4, t155=-10.2, -6.7, -152.6, P<0.05). Conclusions The change in the ceiling-mounted shield positions gave rise to change in radiation dose to the operators. The changes in radiation doses caused by the changes in ceiling-mounted shield positions are different in various angiographic positions. Ceiling-mounted shield should be used in a reasonable way in agreement with different positions in percutaneous coronary intervention so as to effectively reduce operators radiation dose. |
