Brain 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 کاملBronchial 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 کاملInduction of ventricular arrhythmia by high and low osmolarity ionic and nonionic contrast media.
Studies that used prolonged contrast media infusion in canine arteries have generated controversy regarding the arrhythmogenic potential of low osmolarity, nonionic contrast agents. In order to establish the relative safety of these agents in the more typical setting of bolus injections, 4 ml intracoronary bolus injections of Hypaque-76 (n = 54), Iohexol-350 (n = 51), and Iohexol-140 (n = 51) w...
متن کاملComparison of side effects during cerebral computed tomography with a nonionic (iohexol) and an ionic (metrizoate) contrast medium.
Cerebral computed tomography was performed in 60 patients referred for pre- and postcontrast scanning. The patients were randomly sampled with a nonionic contrast medium, iohexol, and an ionic contrast medium, sodium metrizoate. No complications were seen, and the adverse effects, usually a feeling of warmth, were very minor with both contrast media, but iohexol caused less discomfort than sodi...
متن کاملAnaphylactic Shock Following Nonionic Contrast Medium during Caudal Epidural Injection
Caudal epidural injection is a common intervention in patients with low back pain and sciatica. Even though the complications of fluoroscopically directed epidural injections are less frequent than in blind epidural injections, complications due to contrast media can occur. We report a case of anaphylactic shock immediately after injection of an intravenous nonionic contrast medium (iohexol) du...
