The effect of the bedside protection against different operators in percutaneous coronary intervention

Objective: To discuss the effect of the bedside shielding protection on the first and second operators against position radiation in percutaneous coronary intervention. Methods: The surface entrance dosage rate for the first and second operators at 125 cm height with and without radiation protection shielding (provided separately) were measured. The t-test was used for statistical analysis of arithmetic mean values of dosage rates. And the effect of bedside shielding protection was calculated. Results: The position radiation dosage rate at which the first operator exposed was significantly higher than that for the second in the case of no bedside protection (t = 97.1-2 263.0, P < 0.05), whereas the dosage rate at which the first operator (except for the left foot position) exposed was significantly lower than that for the second in the case of no bedside protection (t = -80.9-275.1, P < 0.05). The shielding effect of bedside protection on the first and second operators was in the range of 92.26%-99.36% and 27.83%-97.90%, respectively. Conclusions: The bedside protection may effectively reduce position radiation dose to patients and the use of bedside protection changed the trends in the dose distribution in operators' standing region. Attention should be focused on the radiation protection of the second operators in daily work by making full use of bedside protection. (authors)
