Abstract
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.关键词
