【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 ,可大大减少
[Abstract]:Objective after the embedded depleted uranium bomb is removed, there is still high concentration of depleted uranium contamination in the surrounding tissue. It is important to study which method can minimize the contamination and reduce the damage to the body. Methods after 10 days of operation, depleted uranium tablets were implanted in anesthetized animals. After 10 days, they were divided into conventional operation group, preoperative 4% sodium bicarbonate decontamination group, wound decontamination group, and surgical instrument replacement group. The tissue samples were collected on day 7, 1421, and the uranium content was determined by cutting off the surrounding tissue group and the comprehensive method group. Results the uranium content was the highest in routine operation group, followed by preoperative decontamination group, incision decontamination group and replacement instrument group. Conclusion the comprehensive application of various methods to perform surgery, that is, 4% sodium bicarbonate decontamination incision decontamination and replacement instrument scissors to remove the surrounding tissue is the best, can greatly reduce
