目的 探讨品管圈(Quality Control Circle, QCC)活动对降低造影剂外渗的效果观察。方法 根据QCC的方法和步骤,成立QCC小组,通过比较和分析QCC活动实施前后外渗率的变化,找出导致CT增强扫描前接受高压静脉造影剂注射外渗的主要原因,提出针对性的改进措施并分析其效果。结果 QCC活动实施前外渗率达0.17%,而实施后外渗率为0.07%,差异有统计学意义(P<0.05)。结论 开展QCC活动可降低CT增强扫描前造影剂外渗发生率,值得临床推广应用。

Objective To investigate the effect of quality control circle (QCC)activity on reducing contrast agent extravasation. Methods According to the steps and methods of the quality control circle, a QCC group was set up to compare and analyze the data before and after the implementation of QCC activities to find out the main reason for the extravasation of high-pressure intravenous contrast agent injection before CT enhanced scanning, and put forward targeted improvement measures to analyze its effect. Results The extravasation rate before QCC activity was 0.17%, and the extravasation rate after implementation was 0.07%, the difference was statistically significant (P <0.05). Conclusion Carrying out QCC activities may reduce the incidence of contrast agent extravasation before CT enhanced scanning, which is worthy of clinical application.
