介入诊疗中提倡使用等渗性对比剂

影像诊断和介入治疗技术的快速发展使对比剂的临床应用越来越普遍,与对比剂相关的不良事件亦日益受到医学界的重视.对比剂肾病是临床最常见的对比剂相关不良事件,对比剂的神经毒性反应也开始受到临床医师的关注.等渗性对比剂的渗透压接近血浆,其安全性和耐受性较低渗性对比剂更好.因此,在临床工作中应提倡使用等渗对比剂,这对减少对比剂不良事件具有重要意义.

Recommendation to use iso-osmotic contrast medium in interventional treatment

With the rapid development of imaging diagnostic and interventional therapeutic techniques,the contrast medium(CM) has been used more and more common in clinical practice,and meanwhile more and more attention has been paid to the CM-related adverse events.Contrast induced nephropathy(CIN) is the most common CM-related adverse event,and CM-related neurotoxicity has already attracted the physicians’ attention.The osmotic pressure of the iso-osmotic contrast medium(IOCM) is quite the same as that of the plasma,and therefore its safety is higher than that of low-osmotic contrast medium (LOCM),the patient’s tolerance to IOCM is better than that to LOCM.For this reason,the use of IOCM should be strongly recommended in interventional procedures,which is of great significance to the reduction of the occurrence of CM-related adverse events.
