CT增强扫描定位是指经静脉注入含碘有机化合物即造影剂同时进行CT扫描,其目的是增强病灶与周围正常组织对比,更清晰显示病灶的范围。由于CT增强扫描定位时注射速度快、压力大,造影剂浓度高,再加上肿瘤患者化疗后血管弹性差,血管阻力大,患者配合不够充分等原因,易造成造影剂外渗,引起局部肿胀、疼痛,甚至引起严重的并发症。本文对我科56例造影剂外渗患者的护理进行总结报告如下。
CT enhanced scan positioning refers to the intravenous injection of iodine-containing organic compounds that contrast agent CT scan at the same time, its purpose is to enhance the lesions compared with the surrounding normal tissue, more clearly shows the extent of lesions. Because CT enhanced scan positioning injection speed, pressure, high contrast agent concentration, coupled with cancer patients after chemotherapy poor vascular elasticity, vascular resistance, patients with inadequate and other reasons, easy to cause contrast agent extravasation, causing local swelling , Painful and even cause serious complications. This article 56 cases of our department of contrast media extracorporeal care nursing summary report is as follows.
