Ionic and Non‐Ionic Contrast Media: Current Practice in the Major Hospitals of Australia and New Zealand

Abstract

Major hospitals in Australia and New Zealand were surveyed to estimate the extent of conversion to non-ionic and/or low-osmolar media. The results indicate that conventional ionic media now comprise only approximately one-third of the total usage.

A Survey of Risk Factors for Adverse Reactions to Intravenous Contrast Media

“…The relative use of the two types of media in the patients surveyed (Table 3) indicates that there has been a further shift to the use of nonionic media since the survey of practice in May 1989 (Palmer 1989). At that time, the use of nonionic media was recorded in 60% of patients receiving intravenous contrast media in Australian hospitals.…”

“…guidelines (1986) and a survey of hospitals in May 1989 showed that conventional ionic media were being used in only 31% of patients. Total conversion had occurred in one third of hospitals (Palmer 1989).…”

A century of urinary tract radiology in Australasia

“…As the century draws to a close, the use of non-ionics is becoming universal in Australasia. 26 To reduce the expense of non-ionic contrast media, further studies on the optimal dosage for non-ionic urography were made and Eagar et aLZ7 in Christchurch and Keenan et a/. ** in Auckland have recommended modifications.…”
