Development of Anaphylaxis Surveillance System for Iodinated Contrast Media at Suratthani Hospital

Abstract

This article focuses on a significant public health issue—the occurrence of allergic reactions to contrast media used in radiological examinations, which has shown an increasing trend alongside rapid advancements in medical technology. The objective is to develop an appropriate initial management system for patients experiencing severe allergic reactions to contrast media and to reduce subsequent complications. A multidisciplinary working group was established, consisting of physicians, pharmacists, nurses, and other related personnel, to monitor allergic reactions in two stages: before and after contrast administration. The results showed improved patient safety, with reductions in the incidence of renal failure and extravasation of contrast media. In conclusion, the use of nonionic iodinated contrast media (nonionic ICM) has significantly decreased the mortality rate from allergic reactions to only 0.1 per 100,000 patients. Therefore, the Radiology Department of Surat Thani Hospital has developed a comprehensive monitoring system for severe contrast media allergy to enhance efficiency and patient safety in clinical practice.
