Monitoring the iodine dose

The administration of large amounts of iodinated contrast media can result in acute renal failure. Many diagnostic examinations, including pyelography, computed tomography and digital vascular imaging, require the injection of significant amounts of contrast media. Additionally, these examinations may be performed within 24-48 hours of each other, increasing the likelihood of a dose-induced acute renal failure. To avoid this complication, we have developed and implemented a system to monitor and control the patient's dose of iodine. This system effectively alerts individuals to the iodine dose the patient has received within the last 48 hours. The information is being used to compile a study concerning the relationship between iodine dose and the occurrence of acute renal failure.
