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.

目的 对经皮冠状动脉介入(PCI)治疗术前高敏C反应蛋白(hs-CRP)水平进行测定,探究其与患者术后发生造影剂肾病相关性。方法 选取2011年4月—2013年5月在我院进行PCI手术疗的患者120例为实验对象。根据术前hs-CRP值分为3组:A组(hs-CRP<1 mg/L,n=56),B组(hs-CRP 1～3 mg/L,n=40)和C组(hs-CRP>3 mg/L,n=24)。观察各组术后造影剂肾病的发生情况以及探究其两者之间的相关性。结果 A、B、C组患者术后CIN的发生率分别为8.93%、22.5%和50.0%,经过统计学比较,差异有统计学意义(P<0.05)。患者术前hs-CRP水平年龄在75岁以上、男性、糖尿病、贫血、水化治疗均与CIN显著独立相关。C组MACE发生率均高于A组、B组(P<0.05)。结论 接受PCI手术治疗的患者,其术前hs-CRP水平与其术后CIN的发生具有一定的相关性,患者术前hs-CRP水平越高,术后更可能发生CIN,hs-CRP的水平可作为辅助CIN诊断的指标。
