[Prevention of adverse reactions to contrast media by means of general anesthesia?].

Adverse reactions to systemically administered contrast media are a threat to patients as well as the responsible physician. Non-ionic media produce less side effects due to the lower osmolarity and an advantageous chemical structure. Suggested prophylactic measures include the intravenous administration of H1- and H2-receptor blockers the administration of corticosteroids, sedatives and general anaesthesia. General anaesthesia not necessarily protects from a reaction to either ionic or nonionic compounds and bears its own risks.
