Title

Iodinated Contrast Media, Part 2: Managing Adverse Reactions (1 credit hours)

Abstract

Content in this module contains material previously published as the modules Iodinated Contrast Media, Pt 3: Managing Adverse Reactions. If you have already completed this module, you are not eligible to take this new course for CE credit.

The content of this course is applicable to all areas of healthcare. Regardless of the procedure, be it coronary angioplasty, colonoscopy or IV contrast studies, patients can experience adverse medical events. In all cases, patient management should commence with a thorough primary assessment and oxygenation. Once this is completed a decision can be made regarding further intervention. This course will explain appropriate interventions and drug protocols for patients who demonstrate such adverse reactions as abnormalities in blood pressure, cardiac complications, bronchospasm, allergic and pseudoallergic reactions, diabetic complications, and convulsive seizures. This activity is approved for Category A credits by the ASRT/Expiration date July 1, 2010.

This activity may be available in multiple formats or from different sponsors. The ARRT does not allow CE activities such as internet courses, home study programs or directed readings to be repeated for CE credit in the same or any subsequent biennium.

Author

Dan Becker, DDS

Dr. Becker received his bachelor of science in zoology from Ohio University in 1968 and his doctor of dental surgery from Ohio State University in 1972. Although Dr. Becker is a dentist, his interest always centered on academia and he began teaching biology at Sinclair Community College (Dayton, OH) as a part-time instructor in the autumn of 1972. He accepted a full-time faculty position in the Dental Hygiene department in 1976, but continued his teaching within the Biology department as well.

Dr. Becker's interest in pharmacology and anesthesia attracted him to Miami Valley Hospital where he became involved with their dental residency instructing dental residents and learning from mentors during rotations within departments of anesthesia and emergency medicine. During this time, he developed and taught courses in pharmacology and pathophysiology for nursing and other allied health programs until his teaching at Sinclair became entirely devoted to these subject areas. Currently he is a full professor at Sinclair Community College and Associate Director of Education at Miami Valley Hospital. He has published in numerous scientific journals and textbooks, and lectures extensively throughout the United States and Canada.

Objectives

After studying the information presented, the reader should be able to:

Explain the features of primary assessment and oxygen delivery that should be initiated for any adverse reaction to contrast media.
Recognize and describe appropriate emergency care interventions and drug protocols for patients who experience specific adverse events during contrast media studies.
