Electronic Consultation Support System for Radiocontrast Media Hypersensitivity Changes Clinicians' Behavior

Electronic Consultation Support System for Radiocontrast Media Hypersensitivity Changes Clinicians' Behavior

PURPOSE Patients with a history of radiocontrast media (RCM) hypersensitivity can be overlooked, resulting in repeated reactions. Therefore, a consultation support system for RCM hypersensitivity has been in operation at Seoul National University Bundang Hospital since December 2011. We analyzed the effect of this system on physicians' practice. METHODS A retrospective study was conducted on ...

Radiocontrast media hypersensitivity in the Asia Pacific region

Radiocontrast media (RCM) is a major cause of drug hypersensitivity reactions as the medical application of RCM is increasing recently. RCM induced hypersensitivity reactions are considered as unpredictable type B reactions. Underlying mechanism of RCM induced hypersensitivity was previously regarded as nonimmunological mechanisms but recent studies suggest that immunological mechanisms could a...

The Effectiveness of Automatic Recommending System for Premedication in Reducing Recurrent Radiocontrast Media Hypersensitivity Reactions

BACKGROUND Non-ionic radiocontrast media (RCM) is rarely associated with hypersensitivity reactions. Premedication of patients who reacted previously to RCM with systemic corticosteroids and/or antihistamines can help reduce recurrent hypersensitivity reactions. However, premedication is still not prescribed in many cases for various reasons. This study aimed to determine the effectiveness of o...

Effectiveness of premedication for hypersensitivity reactions to radiocontrast media in one tertiary hospital

Results A total of 401 patients with a history of hypersensitivity reaction to RCM and were premedicated at re-exposure to RCM. Male was 177 (44.1%) and mean age was 55.83¡3⁄411.92 years. Most common hypersensitivity symptom was urticaria (259, 64.6%), followed by itching (36.7%), rash (21.4%) and angioedema (13.2%). Hypotension was reported in 9 (2.2%) and syncope 5 (1.2%). Systemic steroid wa...
