【摘要】 目的 探讨新型一体化携125I粒子双链胆道引流管(粒子引流管)治疗恶性梗阻性黄疸患者术后即刻辐射剂量率的监测与防护措施。方法 2017年9月至2020年9月,35例恶性梗阻性黄疸患者首次接受粒子引流管治疗,术后即刻监测手术侧、对侧在有无防护措施下0、15、30、45、60、75和90 cm处的γ射线辐射量率,并与天然本底测量值比较,进而提出针对性护理防护措施。结果 无铅衣防护状态下,术后手术侧γ射线辐射量率在0、15、30、45、60 cm 处分别为 24.5、13.0、7.2、2.7、1.7 μSv/h,对侧为12.8、4.3、1.7、1.8、1.7 μSv/h,在术侧60 cm处及对侧30 cm内,剂量率与天然本底有统计学差异(P<0.05)。而铅衣防护状态下,所有监测值均与本底值差异无统计学意义(P>0.05)。结论 梗阻性黄疸患者置入粒子引流管后,无铅衣防护状态下,在手术侧60 cm以外或手术对侧30 cm以外的距离操作为宜,可减少对医护人员的辐射。
