Bronchial vasodilatory response to ionic and nonionic contrast media.
It has recently been shown that bronchial arterial injection of conventional contrast medium causes a significant increase in bronchial blood flow (Qbr) and that this response is partially attenuated after infusion of N omega-nitro-L-arginine (L-NNA). However, the precise mechanism for this increase in Qbr is unknown. In this study we examined the effect of bronchial arterial injection of conve...
متن کاملNonionic contrast media: economic analysis and health policy development.
The replacement of old radiologic contrast media with supposedly safer but more expensive media has created a dilemma for radiologists and hospital administrators. To quantitate the nature of this trade-off we performed a cost-utility analysis using optimistic assumptions that favoured the new media. A complete conversion to the new media would result in an incremental cost of at least $65,000 ...
متن کاملBrain parenchyma penetration by intrathecal ionic and nonionic contrast media.
Metrizamide, a nonionic water-soluble contrast medium, has been shown to penetrate normal brain when injected intrathecally. Recently it was suggested that the complications following intrathecal metrizamide are directly related to the cerebral concentration reached. Metrizamide, both in experimental animals and clinically, is regarded as less neurotoxic than equivalent iodine concentrations of...
متن کاملTime to abandon nonionic contrast.
E very year, over 1 0 million Intravascular contrast examinations are performed In the United States. A typical dose of 200 mL of high-osmolality Ionic radiographic contrast costs approximately $8 (e.g. , diatrizoate, iothalmate, and others). In comparIson , low-osmolality nonionic contrast costs up to $ 1 70 for equivalent volumes (e.g. , iopamldol. iohexol. and others). If nonlonic contrast w...
متن کاملFrequency, outcome, and appropriateness of treatment of nonionic iodinated contrast media reactions.
OBJECTIVE The objective of our study was to evaluate the frequency, outcome, and appropriateness of treatment of adults with acute allergiclike reactions related to IV-administered nonionic iodinated contrast media. MATERIALS AND METHODS For IV injections of nonionic iodinated contrast media between January 1, 1999, and December 31, 2005, contrast reaction reports and medical records of patie...
