摘　　要：目的 构建CT增强检查中碘对比剂静脉外渗风险评估指标,以便降低静脉外渗的发生。方法 在文献检索基础上初步拟定风险评估指标,采用Delphi法进行两轮专家函询,完成评估指标的构建。结果 两轮专家函询积极性系数为100.00%、90.91%;权威程度系数分别为0.90、0.93;协调系数分别为0.425、0.447,具有统计学差异(均P<0.001),构建的碘对比剂静脉外渗风险评估指标包括4个一级指标及31个二级指标:患者个人因素(10个指标)、护士因素(3个指标)、碘对比剂因素(7个指标)及静脉注射相关因素(11个指标)。结论 本研究编制的评估指标经统计分析,函询结果 具有一定的可靠性、科学性,可为外渗风险评估管理实践提供指引,期望能有效预防碘对比剂静脉外渗的发生。Objective To develop risk indicators for venous extravasation of iodine contrast medium in contrast enhanced CT scan, in order to reduce the occurrence of venous extravasation. Methods On the basis of literature review, the said risk assessment system was formulated. Delphi method was used to conduct two rounds of expert consultations to complete the items for investigation.Results The enthusiasm coefficients of the two rounds of expert consultation were 100.00% and 90.91%;the authority coefficients were0.90 and 0.93;the coordination coefficients were 0.425 and 0.447, with statistical differences for all the three coefficients( P<0.001). The risk assessment system was composed with 4 Tire-1 indicators and 31 Tire-2 indicators. The indicators specifically covered personal factors of patients(10 indicators), factors of catheterisation by nurses(3 indicators), iodine contrast medium-related factors(7 indicators) and intravenous injection-related factors(11 indicators). Conclusions By statistical analysis, the results of consultation are reliable, scientific and practical. It provides guidance for the management of the risk assessment of extravasation and effectively prevents the occurrence of venous extravasation of iodine contrast medium.
