新型悬浮式防护服防X线辐射效果、可操作性和舒适性评价

A new suspension type of radiation-protective clothing: evaluation of its radiation-protective effect,maneuverability and comfortableness

目的 评估新型悬浮式防护服防X线辐射效果、可操作性和舒适性。方法 分别检测悬浮式防护服与普通防护服在第1、第2术者位置头部、胸部、腹部、下肢、足部辐射剂量率(μSv/h)。15名介入放射科医师先后穿普通防护服、悬浮式防护服参与模拟手术,对防护服可操作性及舒适性进行独立评分。结果 悬浮式防护服与普通防护服相比,明显降低了第1、2术者胸部、腹部、下肢部位射线剂量率(t=135.5~1 688.9,P<0.01),同时有效保护了头部、足部免受高辐射剂量伤害。悬浮式防护服可操作性评分虽低于普通防护服,但差异无统计学意义(Z=-1.826,P=0.103);舒适性评分明显优于普通防护服(Z=-3.482,P<0.000 1)。结论 与普通防护服相比,新型悬浮式防护服具有良好的整体防护性能和舒适性,且不影响手术操作。

Objective To evaluate the radiation-protective effect, maneuverability and comfortableness of a new suspension type of radiation-protective clothing. Methods The radiation dose rate （μSv/h） at the head, chest, abdomen, lower limbs and feet of both first and second operators when they wore suspension type of radiation-protective clothing and wore ordinary lead clothing were separately determined. Fifteen interventional radiologists participated in the simulated surgery, wearing ordinary lead clothing and suspension type of radiation-protective clothing in turn, and independently gave scores for the maneuverability and comfortableness of radiation-protective clothing. Results Compared with the ordinary lead clothing, the suspension type of radiation- protective clothing significantly reduced the radiation dose rate at the chest, abdomen, lower limbs of both first and second operators （t=135.5-1 688.9, P〈0.01）, meanwhile, it effectively protected the head and feet from high radiation dose injury. No statistically significant difference in maneuverability score between the suspension type of radiation- protective clothing and the ordinary lead clothing （Z=-1.826, P=0.103）, although the maneuverability score of the suspension type of radiation- protective clothing was lower than that of the ordinary lead clothing. The comfortableness score of the suspension type of radiation-protective clothing was remarkably higher than that of the ordinary lead clothing （Z=-3.482, P〈0.000 1）. Conclusion Compared with the ordinary lead clothing, the novel suspension radiation-protective clothing has excellent overall radiation-protective property and comfortableness, besides, the wearing of the novel suspension radiation-protective clothing will not affect the operative manipulation.
