摘要
目的 取出嵌入的贫铀弹片后 ,其周围组织中仍有高浓度的贫铀污染 ,研究何种取片方法能最低限度减轻这种污染 ,对减轻机体损伤有重要意义。方法 动物麻醉状态下手术植入贫铀片 ,10d后以各种不同的方法取出 ,分为常规手术组、术前 4%碳酸氢钠去污组、创口去污组、更换手术器械组、剪去周围组织组和综合法组 ,在取片后第 7、14、2 1天收集组织样本 ,测定铀含量。结果 以常规手术组组织铀含量最高 ,术前去污组、切口去污组和更换器械组次之 ,剪去周围组织铀含量下降较大 ,综合组最低。结论 综合应用各种方法实行手术 ,即术前 4%碳酸氢钠去污 +切口去污 +更换器械 +剪去周围组织效果最好 。
Objective To find out the best method for elimination of uranium contamination in rat tissues as low as possible by removal of shrapnel fragments. Methods Experimental rats were divided into six groups: route group, decontamination before surgery group, decontamination in incision group, changing surgical appliances group, removing tissues around group, and comprehensive method group. Uranium concentrations in tissues and fluids in all groups were measured at 7, 14, and 21 d after operation. The efficiency of decontamination by different methods was compared. Results The highest uranium concentration in tissues was found in the route group, but the lowest in the comprehensive method group, and the second lowest in removing tissues around group. Conclusion The comprehensive method is the best one in all of the surgical removal methods. The soft tissues around DU shrapnels should be removed if they are not critical organs.
