背景:回顾性调查口腔内手术室工作人员的散射辐射(SCR)暴露情况。
方法:在透视引导下的手术中,五个专业团体(泌尿外科医生[美国],外科护士[SN],外科助理护士[ASN],麻醉师[A],和麻醉护理[AC])在2023年7月至2024年2月之间,在铅围裙上的头部和胸部佩戴了实时剂量计(飞利浦DoseAwareSystem)。分析了SCR数据,并将其与程序和患者因素相关联。
结果:总计,进行了249次手术,包括86例逆行肾内手术和10例经皮肾镜取石术。美国胸部(USC)的SCR暴露中位数为38.81、17.20、7.71、11.58、0.63、0.23、0.12和0.15Microsievert(µSv),美国元首(USH),SN胸部(SNC),SN头部(SNH),胸部(AC),AC胸部(ACC),ASN胸部(ASNC),和ASN头(ASNH),分别。USC检测到的DAP和SCR剂量之间存在显着相关性,USH,SNC,SNH,AC,和ACC剂量计(p<0.05)。美国的中位胸眼转换因子(CECF)为2.11,SN为0.71。
结论:这项研究,使用实时剂量测定,是第一个评估人员在腔内泌尿外科职业SCR暴露的专家之一。它突出了大量的SCR暴露,表明存在职业健康危害,值得进一步调查。
BACKGROUND: To retrospectively investigate scatter radiation (SCR) exposure among staff in the endourology operating theatre.
METHODS: During surgeries under fluoroscopic guidance, five professional groups (urological surgeon [US], surgical nurse [SN], assistant surgical nurse [ASN], anaesthetist [A], and anaesthesia care [AC]) wore real-time dosimeters (Philips DoseAware System) on their head and chest over lead aprons between July 2023 and February 2024. The SCR data were analysed and correlated with procedural and patient factors.
RESULTS: In total, 249 procedures were performed, including 86 retrograde intrarenal surgeries and 10 percutaneous nephrolithotomies. Median SCR exposure was 38.81, 17.20, 7.71, 11.58, 0.63, 0.23, 0.12, and 0.15 Microsievert (µSv) for US chest (USC), US head (USH), SN chest (SNC), SN head (SNH), A chest (AC), AC chest (ACC), ASN chest (ASNC), and ASN head (ASNH), respectively. There was a significant correlation between DAP and SCR doses detected by USC, USH, SNC, SNH, AC, and ACC dosimeters (p < 0.05). The median chest-to-eye conversion factor (CECF) was 2.11 for the US and 0.71 for the SN.
CONCLUSIONS: This study, using real-time dosimetry, is among the first to assess staff occupational SCR exposure in endourology. It highlights a substantial SCR exposure, indicating an occupational health hazard that warrants further investigation.
