随着现代科学的不断发展,影像诊断仪器及技术也在不断改进、提高。放射学的检查方法尤其是造影检查越来越多,也更趋复杂。造影剂中用处广泛的含碘的离子造影剂是高渗性溶液。正常情况下静脉注射可有扩张血管的性质,大剂量注射后可导致血压和周围血管阻力下降,最严重的是个别人有过敏反应。因此对造影剂的显像质量、病人的安全性提出更高的要求,为保证该项检查的顺利进行,就造影剂使用前后如何预防过敏反应几个问题和护理同道们作一探讨。
With the continuous development of modern science, diagnostic imaging equipment and techniques are constantly improving and improving. Radiology examination methods, especially the more and more angiography, but also more complex. The most widely used iodine-containing contrast medium in contrast media is a hypertonic solution. Under normal circumstances may have the nature of intravenous injection of blood vessels, high-dose injection can lead to decreased blood pressure and peripheral vascular resistance, the most serious is that some individuals have allergic reactions. Therefore, the imaging quality of the contrast agent, the patient’s safety put forward higher requirements, in order to ensure the smooth progress of the inspection, on how to prevent allergic reactions before and after the use of contrast agents and fellow fellow for a discussion.
