Contrast Media Extravasation: Manual versus Power Injector

Contrast media extravasation: manual versus power injector.

OBJECTIVE To compare the incidence and complications of extravasation of low-osmolar nonionic contrast media, injected manually and by the automatic power injector (API). SUBJECTS AND METHODS Three thousand five hundred and sixty patients underwent contrast-enhanced abdominal and thoracic computerized tomography scan in the Department of Clinical Radiology, Al-Amiri Hospital, Kuwait, between ...

Extravasation of Contrast Media

Extravasated iodinated contrast media are toxic to the surrounding tissues, particularly to the skin, producing an acute local inflammatory response that sometimes peaks in 24 to 48 hours. The acute tissue injury resulting from extravasation of iodinated contrast media is possibly related primarily to the hyperosmolality of the extravasated fluid. Despite this, the vast majority of patients in ...

MRI and CT contrast media extravasation

BACKGROUND This systematic review combines data from multiple papers on contrast media extravasation to identify factors contributing to increased extravasation risk. METHODS Data were extracted from 17 papers reporting 2191 extravasations in 1,104,872 patients (0.2%) undergoing computed tomography (CT) or magnetic resonance imaging (MRI). RESULTS Extravasation rates were 0.045% for gadolin...

Recognition and management of contrast media extravasation.

Intravenous contrast agents are frequent adjuncts used in diagnostic imaging. Despite the well-recognized complications of contrast media extravasation, its treatment remains an enigma to many. This article reviews the recognition, prevention and treatment options, with a summary of the contrast media extravasation policy implemented in our department.
