目的：比较血管外渗探测技术在不同注射速率和不同穿刺部位下监测对比剂外渗的报警率结果，探讨该技术的临床应用价值。方法：收集接受CT增强扫描的5572例患者资料，将其分为常规增强扫描组和CTA成像组，注射速率分别为2～3 ml/s、4～6 ml/s，所有患者均使用血管外渗探测贴片，每组内穿刺针穿刺部位分为肘正中静脉处及腕关节头静脉起始处，血管外渗探测片平铺或卷铺于皮肤表面。比较不同组别血管外渗探测贴片对对比剂外渗监测报警率。结果：常规增强组中探测贴片平铺1165例，对比剂外渗报警3例；卷铺1921例，报警0例，差异有统计学(x2=4.952，P＜0.05)；CTA组中探测贴片平铺1426例，对比剂外渗报警6例；卷铺1060例，报警0例，差异有统计学意义(x2=4.471；P＜0.05)。探测贴片平铺时对对比剂外渗的监测效果明显优于卷铺。结论：血管外渗探测贴片可监测对比剂外渗的发生，合理、正确使用，有助于降低对比剂外渗发生率，减少对比剂外渗量。

Objective:To compare the alarm rates of contrast agent extravasation at different injection rate of contrast agent in different puncture site using extravasation detection technology ,discuss its clinical application value.Methods: About 5572 cases were underwent CT enhancement scanning from 2012.2-2012.10. All cases were divided into two groups according to the different rate of contrast agent injection: the first group is routine enhanced scanning group, the injection rate of the first group is 2-3ml/s, second group is CTA ,the injection rates is 4-6ml/s, all patients with vascular extravasation detection technology. The foregone groups were divided into two groups according to the different puncture site: the first group of the puncture site at cubital vein, vascular extravasation detection can be tiled on skin; second groups was located in the head start of wrist vein, extravasation detection sheet rolling and spreading on skin. Comparison of different groups of extravasation detection chip alarm rates for contrast agent extravasation monitoring.Results: In the contrast agent injection rate 2-3ml/s group, extravasation detection patch tiled in 1165 cases extravasation contrast alarmed in 3 cases, rolling and spreading in 1921 cases, alarmed in 0 cases, there was a significant difference in statistical analysis showed that among the two (x2=4.952,P<0.05) in the 4-6ml/s group, extravasation detection patch tiled in 1426 cases, 6 cases alarmed, 1060 cases of rolling and spreading, extravasation of contrast and alarm in 0 cases, there was a significant difference in statistical analysis indicated that two (x2=4.471,P<0.05). The detection effect of vascular extravasation detection patch was significantly better in tiling group.Conclusion: On the basic of reasonably and correctly applicate, extravasation detection patch can effectively monitor the contrast agent extravasation occurred, reduce the incidence of extravasation of contrast, decreased the amount of contrast medium extravasation.
